It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims.
In order to facilitate description of embodiments, an application scenario of the embodiments in the present disclosure is simply introduced hereinafter. Referring to
It should be illustrated that the foregoing device categories are exemplary only, and are not restricted by the present disclosure.
In step S11, a user record of a user is acquired, the user record including an identity, position information, recording time and credit information of the user.
The identity of the user may be an IMEI (International Mobile Equipment Identity) of a terminal device of the user, an account number of the user, or the like. The position information may be represented by a GPS (Global Positioning System), or may be represented by a position of a base station or a WIFI (Wireless Fidelity) hotspot to which the terminal device of the user accesses. The credit information is personal credit information collected, collated and saved by a personal credit database established by a specific authority, and is used to provide credit report querying services for commercial banks and individuals, and provide relevant information services for monetary policy making, financial regulation and other functions set forth in laws and regulations.
In step S12, a region where the user locates is determined according to the position information in the user record.
In the present disclosure, one city or a bigger (or smaller) district may be divided into a plurality of regions, and the region where the user locates is one of the plurality of regions. The region may be divided according to the administrative region or be divided according to other manners, for example, be divided according to the business area. Because the business area has relatively concentrated population and strong liquidity, the effect of the security assessment in the present disclosure may be exerted to the maximum extent through dividing the region according to the business area.
In step S13, user records of all users in the region are acquired.
In step S14, a level of security of the region is calculated according to the user records of all the users in the region.
In step S15, the level of security is sent to the user.
The present disclosure determines the region where the user locates according to the user record, then calculates the level of security of the region according to user records of all users in the region, and sends the level of security to the user, thus solving the problem that the prior art cannot determine the level of security of the region where the user locates, and improving the security index of daily life of the user.
In step S20, a user record of a user is acquired, the user record including an identity, position information, recording time and credit information of the user.
The identity of the user may be an IMEI of a terminal device of the user, an account number of the user, or the like. The position information may be represented by a GPS, or may be represented by a position of a base station or a WIFI hotspot to which the terminal device of the user accesses. The credit information is personal credit information collected, collated and saved by a personal credit database established by a specific authority, and is used to provide credit report querying services for commercial banks and individuals, and provide relevant information services for monetary policy making, financial regulation and other functions set forth in laws and regulations.
In the present embodiment, the generating the user record of the user may include: acquiring the user information of the user, the user information including an identity, position information, and time corresponding to the position information of the user; and querying credit information of the user from a credit server according to the identity of the user; and generating the user record according to the identity, the position information, the time corresponding to the position information and the credit information of the user, the recording time in the user record being the time corresponding to the position information.
The credit server may be a server of a third party credit web site, the third party credit website is a website specially engaged in work of collecting, collating and analyzing enterprise and personal credit information, for example, Sesame Credit, and Xiaomi Credit.
The user record is simply and conveniently generated using the foregoing manner; moreover, and subsequent calculation demands may be ensured.
In the present embodiment, acquiring the user record of the user may include: receiving the user information sent by the terminal device of the user, the position information in the user information being GPS information.
Alternatively, acquiring the user record of the user may include: receiving the user information sent by an operator, the position information in the user information being the base station or WIFI hotspot to which the terminal device of the user accesses.
Alternatively, acquiring the user record of the user may include: acquiring the user information from an operator server periodically, the position information in the user information being the base station or WIFI hotspot to which the terminal device of the user accesses.
In step S21, when receiving a security assessment request sent by the user, the user record of the user is acquired, the security assessment request being configured to acquire the level of security of the region.
In other embodiments, the user may launch a security assessment service for the server. After the user launches the security assessment service, the server periodically acquires the user record of the user and carries out subsequent steps. The security assessment service is configured to periodically acquire the level of security of the region.
In step S22, a region where the user locates is determined according to the position information in the user record.
In the present disclosure, one city or a bigger (or smaller) district may be divided into a plurality of regions, and the region where the user locates is one of the plurality of regions. The region may be divided according to the administrative region or be divided according to other manners, for example, be divided according to the business area. Because the business area has relatively concentrated population and strong liquidity, the effect of the security assessment in the present disclosure may be exerted to the maximum extent through dividing the region according to the business area.
In step S23, user records of all users in the region are acquired.
Because the foregoing step S20 may be repeatedly performed for different users, a large number of user records may be generated, and the generated user records will be stored in the server. In step S23, the server finds the user records of all the users located in the region according to the position information and then acquires these user records.
In other embodiments, when acquiring the user record, recording time also needs to be considered except screening the position information, i.e., only partial user records of the region are acquired. For example, the user records of the region having the recording time within a preset range are acquired, wherein the present range may be one month, one week, or the like.
In step S24, the level of security of the region is calculated according to the user records of all the users in the region.
In an implementation manner of the embodiment, calculating the level of security of the region according to the user records of all the users in the region may include: calculating a security factor of the region according to the user records of all the users in the region, the security factor being configured to characterize the level of security of the region; sorting the security factor of the region and security factors of a plurality of preset regions in a descending order, the plurality of preset regions being regions within a preset range of the region where the user locates; and when the security factor of the region where the user locates is one of the top N security factors, determining that the level of security of the region where the user locates is low; and when the security factor of the region where the user locates is one of the last M security factors, determining that the level of security of the region where the user locates is high, M and N being positive integers.
The preset range may be divided by district or by distance, for example, a region which is in the same district as the region where the user locates, or within 10 km from the region where the user locates.
When a city or an urban area includes more regions, the foregoing manner may be employed to calculate the level of security of the region. This calculation method selects regions with high and low degrees of security according to the ordering positions of the security factors, which may remind the user of the relative level of security of the region in the entire city or urban area.
For example, security factors in four regions A, B, C and D of city I are 90, 70, 68 and 50 respectively, and the descending order of the security factors is: A, B, C, D. The top 1 (i.e., the foregoing N) region among the four regions is selected as the region with low level of security, i.e., region A; and the last 3 (i.e., the foregoing M) regions among the four regions are selected as the regions with high degrees of security, i.e., regions B, C and D. Certainly, in the present embodiment, the level of security of the region may be divided into more levels except employing high and low levels to represent the level of security of the region, for example, excellent, good, middle and poor, which are exemplary only and not restrictive of the present disclosure.
Moreover, in the foregoing implementation manner, the security factors may also be sorted in an ascending order.
In another implementation manner of the present embodiment, calculating the level of security of the region according to the user records of all the users in the region may include: calculating a security factor of the region according to the user records of all the users in the region; and when the security factor of the region is greater than a preset value, determining that the level of security of the region is low, and when the security factor of the region is less than or equal to the preset value, determining that the level of security of the region is high.
Compared with the previous manner, this manner is to calculate an absolute level of security, which has a stronger warning effect. The preset value may be set according to actual needs.
For example, in four regions A, B, C and D of city I, the security factors are 90, 70, 68 and 50 respectively, wherein the preset value is 75, then the region A is determined to be the region with low level of security, and the regions B, C and D are determined to be the regions with high level of security.
In the foregoing two implementation manners, calculating the security factor of the given region according to user records in the given region may include: finding out bad credit records from the user records of all the users in the region; and calculating the security factor of the region according to the found bad credit records.
The bad credit record is also called a bad faith record (blemished credit), for example, a bank customer has a late repayment record due to some reasons after applying a loan; at this moment the credit information in the user record is namely a bad credit record.
In the foregoing implementation manner, the security factor of the region is determined by using the credit information. The credit information is used for judging the credibility of one person all the time, while the person with lower credibility usually has higher criminal probability, and the level of security of the region where the user locates is determined by all the users active in the region; therefore, the accuracy of determining the level of security by finding out the bad credit records from the user records of all the users in the region is high.
In embodiments of the present disclosure, the manner identical to that of the region is also employed in a plurality of preset regions for calculating the security, which will not be elaborated herein.
The calculating the security factor of the region according to the found bad credit records may include: acquiring recording time of each of the bad credit records; determining a coefficient corresponding to the recording time of the bad credit record, the coefficient corresponding to the recording time changing from small to big with the recording time being closer to the current time; and calculating a sum of the coefficients corresponding to the recording time of the found bad credit records to obtain the security factor of the region.
For example, there are 100 bad credit records among the user records of all the users in the region D, wherein the recording time of 50 bad credit records is 5 hours ago, the recording time of 25 bad credit records is 1 hour ago, and the recording time of 25 bad credit records is within 1 hour. Accordingly, the coefficients corresponding to the recording time (5 hours ago, 1 hour ago and 1 hour) are respectively 0.2, 0.6 and 1; therefore, the security factor=50*0.2+25*0.6+25*1=50. Certainly, the coefficients corresponding to the recording time herein are exemplary only and are not restrictive of the present disclosure.
In addition, during calculation, the coefficient corresponding to the recording time of the bad credit record is employed for calculation. The farther the recording time from the current time is, the less the probability of the user still in a given region currently is, and therefore the smaller the influence on the level of security is. This calculation method is similarly beneficial for improving the accuracy of the level of security.
In step S25, the level of security is sent to the user.
The above-mentioned step of sending the level of security to the user may include: pushing the level of security of the given region to the terminal device of the user in a form of short message or in other message forms.
In other embodiments, the level of security may be judged before conducting the step S25, and the level of security is sent to the user only when the level of security is low, thus reminding the user of self-protection.
The present disclosure determines the region where the user locates according to the user record, then calculates the level of security of the region according to user records of all users in the region, and sends the level of security to the user, thus solving the problem that the prior art cannot determine the level of security of the region where the user locates, and improving the security index of daily life of the user.
