Description
FIELD OF THE TECHNOLOGY

Embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a method and system for detecting abnormal contact information and a server.


BACKGROUND OF THE DISCLOSURE

With development of communications technologies, communication between people becomes increasingly convenient. A contact list used for storing contact information is provided on many terminals. When a user needs to communicate with a contact or perform another operation on a contact, the user needs to find corresponding contact information in the contact list, and then performs a corresponding operation. In actual application, some contact information, that is, abnormal contact information, is often added to the contact list against the will of the user. The abnormal contact information is, for example, contact information that is added to the contact list by a third-party application installed on a terminal.


In a related technology, whether contact information is abnormal contact information is generally detected according to various rules preset in a rule base. A specific process includes: A terminal obtains, from a server, a rule base pre-established by the server. When new contact information is generated, the terminal analyzes a name, a telephone number, and the like in the contact information to detect whether the contact information matches information indicated by a rule in the rule base. If the contact information matches the information indicated by the rule in the rule base, it indicates that the contact information is abnormal contact information. For example, in a rule in the rule base, when a name of contact information is empty and a label of a telephone number of the contact information carries a special character such as “*”, it indicates that the contact information is abnormal contact information. The server regularly updates the rule base, and a rule is usually manually added or deleted according to experience.


During implementation of the embodiments of the present disclosure, the inventor finds that the foregoing technology has at least the following problem:


In the related technology, the rule base is established by the server according to a preset rule. Each time when the rule base is updated, a rule is manually added to or deleted from the rule base. A quantity of rules in the rule base is relatively small, and the rules are relatively monotonous. Therefore, the accuracy and efficiency of detecting abnormal contact information are relatively low.

DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following further describes the present disclosure in detail with reference to the accompanying drawings. The described embodiments are merely some but not all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure shall fall within the protection scope of the present disclosure.


Referring to FIG. 1, FIG. 1 is a schematic diagram of an implementation environment involved in an embodiment of the present disclosure. The implementation environment may include a server 110 and a terminal 120.


The server 110 may be one server, a server cluster that is formed by several servers, or a cloud computing center.


The terminal 120 may be any apparatus that has a network connection function and multiple application functions and includes a contact list of contact information, and is, for example, a smartphone or a tablet computer.


The server 110 may determine, according to contact information provided by the terminal 120, whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter, generate, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, a target filtering rule indicating a parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter, and then add the target filtering rule to a rule base to obtain an updated rule base. The terminal 120 detects the contact information in a local contact list according to a filtering rule in the updated rule base.


Referring to FIG. 2, FIG. 2 is a method flowchart of a method for detecting abnormal contact information according to an embodiment of the present disclosure. In this embodiment, a description is given by using an example in which the method is applied to the server 110 in the implementation environment shown in FIG. 1. The method includes:


Step 201: Obtain contact information provided by a terminal, where the contact information includes at least one communication attribute parameter, and a parameter characteristic of the communication attribute parameter is used for representing an attribute of a contact in communication.


Step 202: Determine whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter.


Step 203: Generate, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, a target filtering rule indicating a parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter.


Step 204: Add the target filtering rule to a rule base to obtain an updated rule base.


Step 205: Send the updated rule base to the terminal, so that the terminal detects abnormal contact information according to a filtering rule in the updated rule base.


In conclusion, according to the method for detecting abnormal contact information provided in this embodiment of the present disclosure, a server can obtain contact information provided by a terminal, determine whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter, and generate, when the preset communication attribute parameter in the contact information is an abnormal attribute parameter, a target filtering rule indicating a parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter, and add the target filtering rule to a rule base to obtain an updated rule base, so that the terminal detects abnormal contact information according to the updated rule base. Compared with a related technology for detecting abnormal contact information, a rule does not need to be manually added to a rule base, a quantity of rules in the rule base is increased, and rules become varied. Therefore, the accuracy and efficiency of detection are improved.


Referring to FIG. 3-1, FIG. 3-1 is a method flowchart of another method for detecting abnormal contact information according to an embodiment of the present disclosure. In this embodiment, a description is given by using an example in which the method is applied to the server 110 in the implementation environment shown in FIG. 1. The method may include:


Step 301: Obtain contact information provided by a terminal.


The contact information includes at least one communication attribute parameter. A parameter characteristic of the communication attribute parameter is used for representing an attribute of a contact in communication, for example, a contact name, a telephone number, or an email address. For example, the parameter characteristic may include parameter content and a parameter label. The parameter content is content filled in the communication attribute parameter. For example, if the communication attribute parameter is a contact identifier, and the contact identifier is “Xiao Bai” in contact information, parameter content of the contact identifier is “Xiao Bai”. The parameter label is used for identifying the communication attribute parameter. The parameter label is usually preset and constant. For example, if the communication attribute parameter is a contact identifier, a parameter label of the communication attribute parameter is “contact identifier”. For another example, if the communication attribute parameter is an email address, the parameter label of the communication attribute parameter is “email address”.


The communication attribute parameter may be a parameter such as a contact name, a telephone number or an email address. It is assumed that current contact information A1 is: a contact name “Li Si”, a telephone number “13000012311”, and an email address “13000012311@163.com”. All communication attribute parameters of the contact information A1 are the contact name, the telephone number, and the email address. When the communication attribute parameter is the contact name, correspondingly, the parameter content is “Li Si”, and the parameter label is “contact name”. When to communication attribute parameter is the telephone number, correspondingly, the parameter content is “13000012311”, and the parameter label is “telephone number”. When the communication attribute parameter is the email address, correspondingly, the parameter content is “13000012311@163.com”, and the parameter label is “email address”.


After the contact information provided by the terminal is obtained, because the contact information includes communication attribute parameters, some communication attribute parameters may be used as the preset communication attribute parameter. For example, the preset communication attribute parameter may be a contact identifier and a communication number. In this embodiment of the present disclosure, a description is given by using an example in which the preset communication attribute parameter is a contact identifier and a communication number and the parameter characteristic includes parameter content and a parameter label. The contact identifier may be a contact name, or may be another identifier used for representing the contact. The communication number may be a telephone number, or may be another communication number corresponding to the contact.


Step 302: Detect whether parameter content of a contact identifier in the contact information is empty.


The contact identifier may be a contact name. Therefore, it may be detected whether parameter content of the contact name in the contact information is empty.


Step 303: If the parameter content of the contact identifier in the contact information is empty, detect whether a parameter label of a communication number in the contact information is a preset label.


The communication number may be a telephone number. It is assumed that current contact information A2 is: a contact name “”, a telephone number “13000012312”, and an email address “13000012312@163.com”. As can be seen, parameter content of the contact name in the contact information A2 is empty. Therefore, it may further be detected whether a parameter label of the telephone number in the contact information A2 is a preset label (that is “telephone number”). In this embodiment of the present disclosure, the preset label refers to a conventional label, and the conventional label generally does not carry a special character such as ˜, 190 , ^or &. Therefore, if the parameter label of the telephone number in the contact information carries, but is not limited to, the foregoing special character, it may be determined that the parameter label of the telephone number in the contact information is not a preset label. If the parameter label of the telephone number in the contact information does not carry the foregoing special character, it may be determined that the parameter label of the telephone number in the contact information is a preset label. For example, the parameter label of the telephone number in the contact information A2 does not carry a special character. Therefore, the parameter label is a preset label.


Table 1 shows a data structure and data content for storing contact information. The contact information is manually added by a user to a contact list on the terminal. Therefore, parameter content of a contact name in the contact information is not empty, and a preset communication attribute parameter in the contact information is not an abnormal attribute parameter. FIG. 3-2 shows a schematic diagram that the terminal displays the contact information in Table 1.

Table 2 shows a data structure and data content for storing the contact information A2. The parameter content of the contact name in the contact information is empty. Therefore, it needs to be detected whether the parameter label of the communication number in the contact information is a preset label.











TABLE 2





Contact name
Telephone number
Email address


















13000012312
13000012312@163.com










Step 304: If the parameter label of the communication number in the contact information is not a preset label, determine that the preset communication attribute parameter in the contact information is an abnormal attribute parameter.


It is assumed that current contact information A3 is: a contact name “”, a ^telephone number “13000012313”, and an email address “13000012313@163.com”. Because parameter content of the contact name in the contact information A3 is empty, the parameter label of the telephone number carries a special character “^”, and the parameter label of the telephone number is not a preset label, it is determined that a preset communication attribute parameter in the contact information is an abnormal attribute parameter. Table 3 shows a data structure and data content for storing the contact information A3. A server may detect, by reading the data content of the contact information, that the parameter content of the contact name in the contact information A3 is empty, and the parameter label of the telephone number carries a special character “^”.











TABLE 3





Contact name
{circumflex over ( )}Telephone number
Email address


















13000012313
13000012313@163.com










It is noted that in actual application, the parameter label of the communication attribute parameter may be represented by using letters. For example, “contact name” may be replaced by “name” for representation, “telephone number” may be replaced by “haoma” for representation, and “email address” may be replaced by “Email” for representation. In this embodiment of the present disclosure, the parameter label or the parameter content of the preset communication attribute parameter of the abnormal contact information carries a special character. For example “haoma” carries a special character, and becomes “^haoma”.


Step 305: Determine, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter.


The rule base is used for storing a filtering rule for detecting an abnormal contact. For example, the filtering rule may be: contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a parameter label of a communication number in the contact information carries a special character “^”. It is assumed that the current contact information A3 is: a contact name “”, a “^telephone number “13000012313”, and an email address “13000012313@163.com”. The parameter content of the contact name in the contact information is empty, and the parameter label of the telephone number carries a special character “^”, the preset communication attribute parameter is an abnormal attribute parameter, and the rule base stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a parameter label of a communication number in the contact information carries a special character “^”. Therefore, it is considered that the rule base stores a filtering rule indicating the parameter characteristic of the abnormal attribute parameter.


Step 306: Generate, if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter.


Using the contact information A3 in step 305 as an example, assuming that the current rule base does not store a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a parameter label of a communication number in the contact information carries a special character “^”, and stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a parameter label of a communication number in the contact information carries a special character “˜” or “#”, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter is generated according to the abnormal attribute parameter of the contact information A3, where the target filtering rule is that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a parameter label of a communication number in the contact information carries a special character “^”.


Step 307: Add the target filtering rule to the rule base to obtain an updated rule base.


The rule base is used for storing a filtering rule for detecting abnormal contact information. Therefore, if a quantity of filtering rules in the rule base is relatively small, and the filtering rules are relatively monotonous, an effect of detecting abnormal contact information is directly affected. The detection effect includes the length of a time used for detecting abnormal contact information and the accuracy of detecting abnormal contact information.


It is noted that the existing rule base is established by the server according to a preset rule. Each time when the rule base is updated, a rule is manually added to or deleted from the rule base. First, the contact information is manually analyzed, and then a filtering rule is extracted. Efficiency of manual analysis is relatively low, and timeliness is relatively short. In addition, filtering rules in the rule base are liable to errors. Moreover, each time of updating the rule base has highly repetitive operations.


In this embodiment of the present disclosure, a new filtering rule is generated in real time, and the rule base keeps being updated, so that a quantity of rules in the rule base increases and the rules are more varied. Therefore, abnormal contact information can be detected more efficiently. In particular, abnormal contact information that is generated by a third-party application installed on the terminal and is added to the contact list can be detected more efficiently. The third-party application is an application that is not originally installed on the terminal.


Step 308: Send the updated rule base to the terminal, so that the terminal detects abnormal contact information according to a filtering rule in the updated rule base.


After adding the target filtering rule to the rule base to obtain the updated rule base, the server sends the filtering rule in the rule base to the terminal. The terminal reads all contact information in the local contact list, and detects all the contact information according to the filtering rule.


Optionally, in this method, after the updated rule base is sent to the terminal, a rule deletion message sent by the terminal may further be received. The rule deletion message is used for indicating an invalid filtering rule, and the invalid filtering rule is a filtering rule that is in the updated rule base and is not used by the terminal within preset duration. The invalid filtering rule is then deleted according to the rule deletion message after the rule deletion message sent by the terminal is received.


For example, the updated rule base obtained by the server includes ten filtering rules. The server sends the updated rule base to the terminal. The terminal detects abnormal contact information according to the filtering rules in the updated rule base. If one of the ten filtering rules is not used by the terminal within one month, assuming that the filtering rule is G1, the terminal may use G1 as an invalid filtering rule, and send the rule deletion message to the server. After receiving the rule deletion message, the server determines that G1 in the updated rule base that is previously obtained is the invalid filtering rule. Therefore, the server may delete G1. In this way, the rule base is updated in real time by deleting the invalid filtering rule in time, so that the terminal can more efficiently detect abnormal contact information by using a filtering rule in the rule base. In addition, because an invalid filtering rule is deleted, space is further saved.


It is noted that “determine whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter” in step 305, and “if the rule base does not state the filtering rule indicating the parameter characteristic of the abnormal attribute parameter” in step 306 are optional steps. If the preset communication attribute parameter in the contact information is an abnormal attribute parameter, before the target filtering rule indicating the parameter characteristic of the abnormal attribute parameter is generated according to the abnormal attribute parameter, it may be first determined whether the rule base stores the filtering rule indicating the parameter characteristic of the abnormal attribute parameter. If the rule base stores the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, the target filtering rule does not need to be generated. If the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, the target filtering rule is then generated. In this way, it is ensured that no repetitive filtering rules exist in the rule base, so that the terminal can more efficiently detect abnormal contact information by using the rule base. In addition, space is further saved.


In conclusion, according to the method for detecting abnormal contact information provided in this embodiment of the present disclosure, a server can obtain contact information provided by a terminal, determine whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter, generate, if a rule base does not store a filtering rule indicating a parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter, and add the target filtering rule to the rule base to obtain an updated rule base, so that the terminal detects abnormal contact information according to the updated rule base. In addition, the server can delete an invalid filtering rule in time. Compared with a related technology for detecting abnormal contact information, a rule does not need to be manually added to or deleted from the rule base, a quantity of rules in the rule base is increased, and rules become varied. Therefore, the accuracy and efficiency of detection are improved.


Referring to FIG. 4, FIG. 4 is a method flowchart of still another method for detecting abnormal contact information according to an embodiment of the present disclosure. In this embodiment, a description is given by using an example in which the method is applied to the server 110 in the implementation environment shown in FIG. 1. The method may include:


Step 401: Obtain contact information provided by a terminal.


The contact information includes at least one communication attribute parameter. A parameter characteristic of the communication attribute parameter is used for representing an attribute of a contact in communication. For example, the parameter characteristic may include parameter content, and the parameter content is content filled in the communication attribute parameter. After the contact information provided by the terminal is obtained, because the contact information includes the communication attribute parameters, some communication attribute parameters may be used as the preset communication attribute parameter. For example, the preset communication attribute parameter may be a contact identifier and a communication number. In this embodiment of the present disclosure, a description is given by using an example in which the preset communication attribute parameter is a contact identifier and a communication number and the parameter characteristic includes parameter content. For details of step 401, refer to the description in step 301, and details are not described herein again.


Step 402: Detect whether parameter content of a contact identifier in the contact information is empty.


The contact identifier may be a contact name. Therefore, it may be detected whether the parameter content of the contact name in the contact information is empty.


Step 403: If the parameter content of the contact identifier in the contact information is empty, obtain a contact list provided by the terminal,


The contact list provided by the terminal includes the contact information. It is assumed that current contact information A2 is: a contact name “”, a telephone number “13000012312”, and an email address “13000012312@163.com”. Because the parameter content of the contact name in the contact information is empty, the contact list provided by the terminal is obtained.


Step 404: Count a total quantity of the contact information in which the parameter content of the contact identifier is empty in the contact list.


Using the contact information A2 in step 403 as an example, a total quantity of the contact information A2 in the contact list is counted.


Step 405: If the total quantity is greater than a preset quantity threshold, determine that the preset communication attribute parameter in the contact information is an abnormal attribute parameter.


For example, the preset quantity threshold may be equal to 50. If the total quantity that is counted in step 404 and is of the contact information A2 in the contact list is 100, it is determined that the preset communication attribute parameter in the contact information A2 is an abnormal attribute parameter.


Step 406: Determine, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter.


The rule base is used for storing a filtering rule for detecting an abnormal contact. For example, the filtering rule may be contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a total quantity of the contact information in which the parameter content of the contact identifier is empty in the contact list is 100. It is assumed that the current contact information A2 is: a contact name “”, a telephone number “13000012312”, and an email address “13000012312@163.com. The parameter content of the contact name in the contact information is empty, the total quantity of the contact information A2 is 100, the preset communication attribute parameter is an abnormal attribute parameter, and the rule base stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a total quantity of the contact information is 100. In this case, it is considered that the rule base stores a filtering rule indicating the parameter characteristic of the abnormal attribute parameter.


Step 407: Generate, if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter.


Using the contact information A2 in step 406 as an example, assuming that the current rule base does not store a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a total quantity of the contact information is 100, and stores a filtering rule contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a total quantity of the contact information is 70, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter is generated according to the abnormal attribute parameter of the contact information A2, where the target filtering rule is that contact information is abnormal contact information when parameter content of a contact identifier in the contact information is empty and a total quantity of the contact information is 100.


Step 408: Add the target filtering rule to the rule base to obtain an updated rule base.


The rule base is used for storing a filtering rule for detecting abnormal contact information. Therefore, if a quantity of filtering rules in the rule base is relatively small, and the filtering rules are relatively monotonous, an effect of detecting abnormal contact information is directly affected. The detection effect includes the length of a time used for detecting abnormal contact information and the accuracy of detecting abnormal contact information.


Step 409: Send the updated rule base to the terminal, so that the terminal detects abnormal contact information according to a filtering rule in the updated rule base.


After adding the target filtering rule to the rule base to obtain the updated rule base, the server sends the filtering rule in the rule base to the terminal. The terminal reads all contact information in the local contact list, and detects all the contact information according to the filtering rule.


Optionally, in this method, after the updated rule base is sent to the terminal, a rule deletion message sent by the terminal may further be received. The rule deletion message is used for indicating an invalid filtering rule, and the invalid filtering rule is a filtering rule that is in the updated rule base and is not used by the terminal within preset duration. The invalid filtering rule is ten deleted according to the rule deletion message after the rule deletion message sent by the terminal is received. The rule base is updated in real time by deleting the invalid, filtering rule in time, so that the terminal can more efficiently detect abnormal contact information by using the rule base. In addition, because an invalid filtering rule is deleted, space is further saved.


It is noted that “Determine whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter” in step 406, and “if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter” in step 407 are optional steps.

Referring to FIG. 5, FIG. 5 is a method flowchart of yet another method for detecting abnormal contact information according to an embodiment of the present disclosure. In this embodiment, a description is given by using an example in which the method is applied to the server 110 in the implementation environment shown in FIG. 1. The method may include:


Step 501: Obtain contact information provided by a terminal.


The contact information includes at least one communication attribute parameter. A parameter characteristic of the communication attribute parameter is used for representing an attribute of a contact in communication. For example, the parameter characteristic may include parameter content and a parameter label. The parameter content is content filled in the communication attribute parameter, and the parameter label is used for identifying the communication attribute parameter. After the contact information provided by the terminal is obtained, because the contact information includes the communication attribute parameters, some communication attribute parameters may be used as the preset communication attribute parameter. For example, the preset communication attribute parameter may be a contact identifier and a communication number. In this embodiment of the present disclosure, a description is given by using an example in which the preset communication attribute parameter is a contact identifier and a communication number and the parameter characteristic includes parameter content and a parameter label. For details of step 501, refer to the description in step 301, and details are not described herein again.


Step 502: Detect whether parameter content of a contact identifier in the contact information is preset content.


It is assumed that current contact information A4 is: a contact name “Wang Wu &&” a ^telephone number “11000012314”, and an email address “13000012314@163.com”. As can be seen, parameter content of the contact name in the contact information A4 is “Wang Wu &&”. The preset content in this embodiment of the present disclosure refers to conventional content, and the conventional content generally does not carry a special character such as “or &&. Therefore, if the parameter content of the contact name in the contact information carries, but is not limited to, the foregoing special character, it may be determined that the parameter content of the contact name in the contact information is not preset content. If the parameter content of the contact name in the contact information does not carry the foregoing special character, it may be determined that the parameter content of the contact name in the contact information is preset content. The parameter content of the contact name in the contact information A4 carries a special character. Therefore, the parameter content is not preset content.


Step 503: If the parameter content of the contact identifier in the contact information is not preset content, detect whether a parameter label of a communication number in the contact information is a preset label.


The communication number may be a telephone number. It is assumed that the current contact information A4 is: a contact name “Wang Wu &&”, a ^telephone number “13000012314”, and an email address “13000012314@163.com”. As can be seen, the parameter content of the contact name in the contact information A4 is not preset content. Therefore, it may further be detected whether a parameter label of the telephone number in the contact information A4 is a preset label. In this embodiment of the present disclosure, the preset label refers to a conventional label, and the conventional label generally does not carry a special character such as ˜, #, ^ or &. Therefore, if the parameter label of the telephone number in the contact information carries, but is not limited to, the foregoing special character, it may be determined that the parameter label of the telephone number in the contact information is not a preset label. If the parameter label of the telephone number in the contact information does not carry the foregoing special character, it may be determined that the parameter label of the telephone number in the contact information is a preset label. For example, the parameter label of the telephone number in the contact information A4 carries a special character. Therefore, the parameter label is not a preset label.


Step 504: If the parameter label of the communication number in the contact information is not a preset label, determine that a preset communication attribute parameter in the contact information is an abnormal attribute parameter.


If the parameter label of the telephone number in the contact information A4 in step 503 is not a preset label, it is determined that the preset communication attribute parameter in the contact information A4 is an abnormal attribute parameter.


Step 505: Determine, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter.


The rule base is used for storing a filtering rule for detecting an abnormal contact. For example, the filtering rule may be: contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “*” and a parameter label of a communication number in the contact information carries a special character “^”. It is assumed that the current contact information A4 is: a contact name “Wana Wu &&”, a ^telephone number “13000012314”, and an email address “13000012314@163.com”. The parameter content of the contact name in the contact information A4 carries a special character “&&”, the parameter label of the telephone number carries a special character “^”, the preset communication attribute parameter is an abnormal attribute parameter, and the rule base stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a parameter label of a communication number in the contact information carries a special character “^”. Therefore, it is considered that the rule base stores the filtering rule indicating the parameter characteristic of the abnormal attribute parameter.


Step 506: Generate, if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter.


Using the contact information A4 in step 505 as an example, if the current rule base does not store a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a parameter label of a communication number in the contact information carries a special character “^”, and stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “*” and a parameter label of a communication number in the contact information carries a special character “^”, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter is generated according to the abnormal attribute parameter of the contact information A4, where the target filtering rule is that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a parameter label of a communication number in the contact information carries a special character “^”.


Step 507: Add the target filtering rule to the rule base to obtain an updated rule base.


Step 508: Send the updated rule base to the terminal, so that the terminal detects abnormal contact information according to a filtering rule in the updated rule base.


Optionally, in this method, after the updated rule base is sent to the terminal, a rule deletion message sent by the terminal may further be received. The rule deletion message is used for indicating an invalid filtering rule, and the invalid filtering rule is a filtering rule that is in the updated rule base and is not used by the terminal within preset duration. The invalid filtering rule is then deleted according to the rule deletion message after the rule deletion message sent by the terminal is received. The rule base is updated in real time by deleting the invalid filtering rule in time, so that the terminal can more efficiently detect abnormal contact information by using a filtering rule in the rule base. In addition, because an invalid filtering rule is deleted, space is further saved.


It is noted that “Determine whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter” in step 505, and “if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter” in step 506 are optional steps. It is ensured that no repetitive filtering rules exist in the rule base, so that the terminal can more efficiently detect abnormal contact information by using the rule base. In addition, space is further saved.


In conclusion, according to the method for detecting abnormal contact information provided in this embodiment of the present disclosure, a server can obtain contact information provided by a terminal, determine whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter, generate, if a rule base does not store a filtering rule indicating a parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter, and add the target filtering rule to the rule base to obtain an updated rule base, so that the terminal detects abnormal contact information according to the updated rule base. In addition, the server can delete an invalid filtering rule in time. Compared with a related technology for detecting abnormal contact information, a rule does not need to be manually added to or deleted from the rule base, a quantity of rules in the rule base is increased, and rules become varied. Therefore, the accuracy and efficiency of detection are improved.


Referring to FIG. 6, FIG. 6 is a method flowchart of a method for detecting abnormal contact information according to another embodiment of the present disclosure. In this embodiment, a description is given by using an example in which the method is applied to the server 110 in the implementation environment shown in FIG. 1. The method may include:


Step 601: Obtain contact information provided by a terminal.


The contact information includes at least one communication attribute parameter. A parameter characteristic of the communication attribute parameter is used for representing an attribute of a contact in communication. For example, the parameter characteristic may include parameter content, and the parameter content is content filled in the communication attribute parameter. After the contact information provided by the terminal is obtained, because the contact information includes the communication attribute parameters, some communication attribute parameters may be used as the preset communication attribute parameter. For example, a preset communication attribute parameter may be a contact identifier and a communication number. In this embodiment of the present disclosure, a description is given by using an example in which the preset communication attribute parameter is a contact identifier and a communication number and the parameter characteristic includes parameter content. For details of step 601, refer to the description in step 301, and details are not described herein again.


Step 602: Detect whether parameter content of a contact identifier in the contact information is preset content.


For details of step 602, refer to the description in step 502, and details are not described herein again.


Step 603: If the parameter content of the contact identifier in the contact information is not preset content, obtain a contact list provided by the terminal.


The contact list includes the contact information. It is assumed that current contact information A5 is: a contact name “Zhang Wu &&”, a telephone number “13000012315”, and an email address “13000012315@163.com”. Because the parameter content of the contact name in the contact information is not preset content, the contact list provided by the terminal is obtained.


Step 604: Count a total quantity of the contact information in which the parameter content of the contact identifier is not preset content in the contact list.


Using the contact information A5 in step 603 as an example, the total quantity of the contact information A5 in the contact list is counted.


Step 605: If the total quantity is greater than a preset quantity threshold, determine that a preset communication attribute parameter in the contact information is an abnormal attribute parameter.


For example, the preset quantity threshold may be equal to 50. If the total quantity that is counted in step 604 and is of the contact information A5 in the contact list is 100, it is determined that the preset communication attribute parameter in the contact information A5 is an abnormal attribute parameter.


Step 606: Determine, if the preset communication attribute parameter in the contact information is an abnormal attribute parameter, whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter.


The rule base is used for storing a filtering rule for detecting an abnormal contact. For example, the filtering rule may be: contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “*” and a total quantity of the contact information in which the parameter content of the contact identifier carries a special character “*” in the contact list is 100. The parameter content of the contact name in the contact information A5 in step 605 is not preset content, the total quantity is 100, the preset communication attribute parameter is an abnormal attribute parameter, and the rule base stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a total quantity of the contact information in which the parameter content of the contact identifier carries a special character “&&” in the contact list is 100. Therefore, it is considered that the rule base stores the filtering rule indicating the parameter characteristic of the abnormal attribute parameter.


Step 607: Generate, if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter.


Using the contact information A5 in step 606 as an example, assuming that the current rule base does not store a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a total quantity of contact information in which the parameter content of the contact identifier carries a special character “&&” in the contact list is 100, and stores a filtering rule that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a total quantity of the contact information in which the parameter content of the contact identifier carries a special character “&&” in the contact list is 70,a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter is generated according to the abnormal attribute parameter of the contact information A5, where the target filtering rule is that contact information is abnormal contact information when parameter content of a contact identifier in the contact information carries a special character “&&” and a total quantity of the contact information in which the parameter content of the contact identifier carries a special character “&&” in the contact list is 100.


Step 608: Add the target filtering rule to the rule base to obtain an updated rule base.


Step 609: Send the updated rule base to the terminal, so that the terminal detects abnormal contact information according to a filtering rule in the updated rule base.


Optionally, in this method, after the updated rule base is sent to the terminal, a rule deletion message sent by the terminal may further be received. The rule deletion message is used for indicating an invalid filtering rule, and the invalid filtering rule, is a filtering rule that is in the updated rule base and is not used by the terminal within preset duration. The invalid filtering rule is then deleted according to the rule deletion message after the rule deletion message sent by the terminal is received. The rule base is updated in real time by deleting the invalid filtering rule in time, so that the terminal can more efficiently detect abnormal contact information by using the rule base. In addition, because an invalid filtering rule is deleted, space is further saved.


It is noted that “Determine whether a rule base stores a filtering rule indicating a parameter characteristic of the abnormal attribute parameter” in step 606, and “if the rule base does not store the filtering rule indicating the parameter characteristic of the abnormal attribute parameter” in step 607 are optional steps. It is ensured that no repetitive filtering rides exist in the rule base, so that the terminal can more efficiently detect abnormal contact information by using the rule base. In addition, space is further saved.


In conclusion, according to the method for detecting abnormal contact information provided in this embodiment of the present disclosure, a server can obtain contact information provided by a terminal, determine whether a preset communication attribute parameter in the contact information is an abnormal attribute parameter, generate, if a rule base does not store a filtering rule indicating a parameter characteristic of the abnormal attribute parameter, a target filtering rule indicating the parameter characteristic of the abnormal attribute parameter, according to the abnormal attribute parameter, and add the target filtering rule to the rule base to obtain an updated rule base, so that the terminal detects abnormal contact information accordion to the updated rule base. In addition, the server can delete an invalid filtering rule in time. Compared with a related technology for detecting abnormal contact information, a rule does not need to be manually added to or deleted from the rule base, a quantity of rules in the rule base is increased, and rules become varied. Therefore, the accuracy and efficiency of detection are improved.
