The present invention relates to a method for preventing a verification flaw by controlling a session time and a session data traffic. More particularly, the invention relates to a technique whereby a networking equipment records a session time and a session data traffic of a terminal device trying to connect to the Internet through the networking equipment, and whereby the networking equipment cuts off connection with the terminal device when either the session time or the session data traffic exceeds its upper limit, in order to ensure that full network services are accessible to the terminal device only after the user completes a required verification process.
Spurred by the rapid development of computer networks, commercial Internet service providers have grown rapidly in recent years and, in addition to World Wide Web (WWW) services, have begun to provide such network services as network searching, online gaming, network banking, e-mail, digital file transfer through the File Transfer Protocol (FTP), the Bulletin Board System (BBS), and text-oriented communication through the Telnet protocol. Today, thanks to the widespread availability of such network services, people are used to acquiring all sorts of information through the Internet to meet the various needs in their daily lives or at work.
In light of the fact that computer networks have become indispensable tools for not a few, many public places provide access to wireless networks either on payment or free of charge. And from a consumer's perspective, “free wireless networking” has been a major factor in deciding whether or not to patronize a restaurant, coffee shop, hotel, or store. By providing free wireless networking, however, the owner of a place of business expects something in return. For instance, a shop providing free wireless network services may give preferential treatment (e.g., free food offering or a discount) to, and thereby encourage, those who “check into” the shop publicly via a social networking website such as Facebook, Twitter, or Plurk, with a view to the potential advertising effect.
Moreover, with the development of the concept of Big Data, more and more shops have learned to achieve success of advertisement by means of consumers' “network identities” on social networking websites. For example, a shop owner may know a consumer's interests and needs by the consumer's personal data on a social networking website and can therefore target the consumer for sales promotion. This is why many shops that provide free wireless networking require customers to complete a verification process (e.g., logging on to a Facebook account) before they can access free wireless networks. The verification process allows the shops to record the types of their customers so that sales strategies can be adjusted or advertisement, sent out whenever needed.
In order for a consumer to verify their network identify, a shop must create a walled garden in its networking equipment in advance, wherein the walled garden stores the address of a social networking website (e.g., Facebook). When a consumer's terminal device is connected to the networking equipment and requests access to network services, the networking equipment starts by allowing the terminal device to access only the social networking website whose address is stored in the walled garden. Then, the networking equipment requests the consumer to perform a verification process. The networking equipment will not make all its network functions available until a confirmation message indicating “verification completed” is received from the social networking website.
The foregoing verification process, however, has a flaw. If a consumer only needs to use the functions of that social networking website (e.g., browsing Facebook pages that are open to the public) but not the functions of other external networks (e.g., receiving or sending e-mails, or browsing a video website), he or she can do so without verification. The issue to be addressed by the present invention is to provide an easy-to-implement method that can prevent this flaw in verification effectively.
As stated above, even though a shop providing free network services may require its customers to complete a verification process before they are given full access to the services, one may still take advantage of the aforesaid flaw in verification and directly browse a social networking website without going through the verification process. In view of this, the inventor of the present invention put years of practical experience into extensive research, thorough evaluation, and repeated tests and finally succeeded in developing a method for effectively preventing the verification flaw by controlling a session time and a session data traffic as disclosed herein.
It is an objective of the present invention to provide a method for preventing a verification flaw by controlling a session time and a session data traffic. The method is applicable to a networking equipment that stores a list of verified terminal devices, a temporary permit list, a walled garden, an upper limit of time, and a data traffic quota, wherein the walled garden stores the social networking website address of at least one social networking website server. The networking equipment starts a verification process after receiving a request from a terminal device and determining that the media information of the terminal device has yet to be recorded on the list of verified terminal devices. The method includes the steps, to be performed by the networking equipment during the verification process, of: adding the media information to the temporary permit list, and starting to record a session time and a session data traffic, wherein the session time refers to the time for which the terminal device has been connected to the networking equipment while the session data traffic refers to the amount of data transmitted by the networking equipment to the terminal device; receiving a frame from the terminal device, and updating the session data traffic according to the amount of data in reply to the frame; sending the frame to the target address of the frame when, and only when, it is determined by the networking equipment that the session time does not exceed the upper limit of time, that the session data traffic does not exceed the data traffic quota, and that the target address of the frame corresponds to one of the at least one social networking website address in the walled garden; and receiving a confirmation message from the social networking website server corresponding to the social networking website address to which the target address of the frame corresponds, and recording the media information on the list of verified terminal devices to conclude the verification process. With the networking equipment monitoring the session time and session data traffic of the terminal device continually while the terminal device undergoes verification, the user of the terminal device is easily and effectively prevented from using the social networking website intended for verification without actually completing the verification process after the terminal device is connected through the networking equipment to the corresponding social networking website server.
The technical features, process flow, and objectives of the present invention can be better understood by referring to the following detailed description in conjunction with the accompanying drawings, in which:
The present invention provides a method for preventing a verification flaw by controlling a session time and a session data traffic. Referring to
The networking equipment 11 at least includes a processing unit 110, an ingress direction module 111, an egress direction module 112, and a storage module 114, wherein the processing unit 110 is provided therein with a captive portal module 113. When the terminal devices 12 are connected to the networking equipment 11, the networking equipment 11 can receive data through the ingress direction module 111 and send data through the egress direction module 112.
The storage module 114 of the networking equipment 11 stores a list of verified terminal devices T1, a temporary permit list T2, a walled garden T3 (including the website address of Facebook for example), an upper limit of time V1 (e.g., 5 minutes), and a data traffic quota (e.g., 10 MB). The walled garden T3 stores the social networking website address of at least one social networking website server 13 (e.g., 192.168.10.10).
When any of the terminal devices 12 is connected to the networking equipment 11, a request for access to the network services provided by the networking equipment 11 is sent by the terminal device 12 to the networking equipment 11. Upon receiving the request, the networking equipment 11 determines whether the media information (e.g., the media access control address, or MAC address) of the terminal device 12 is already recorded on the list of verified terminal devices T1. If, referring to
Conversely, if it is determined by the networking equipment 11 that the media information of the terminal device 12 (e.g., “00-90-27-10-30-25”) is not on the list of verified terminal devices T1, the networking equipment 11 will start a verification process and guide the following process flow to the captive portal module 113. Hereinafter, a detailed description of the method of the present invention, or more particularly of the steps to be performed by the networking equipment 11, is provided with reference to
(301) To begin with, the networking equipment 11 adds the media information to the temporary permit list T2 and starts recording a session time and a session data traffic. The session time refers to the time for which the terminal device 12 has been connected to the networking equipment 11. The session data traffic refers to the amount of data transmitted by the networking equipment 11 to the terminal device 12.
(302) After that, the networking equipment 11 receives a frame from the terminal device 12 and updates the current session data traffic according to the amount of data in reply to the frame (i.e., the amount of data the networking equipment 11 has sent to the terminal device 12 in reply to the frame, e.g., 2 MB).
(303) The networking equipment 11 determines whether the session time exceeds the upper limit of time V1. If yes, the networking equipment 11 stops the ongoing process, cuts off the connection between the networking equipment 11 and the terminal device 12, and removes the media information of the terminal device 12 from the temporary permit list T2; if no, step (304) is performed.
(304) The networking equipment 11 determines whether the session data traffic exceeds the data traffic quota V2. If yes, the networking equipment 11 stops the ongoing process, cuts off the connection between the networking equipment 11 and the terminal device 12, and removes the media information of the terminal device 12 from the temporary permit list T2; if no, step (305) is carried out.
(305) The networking equipment 11 determines whether the target address of the frame corresponds to any social networking website address in the walled garden T3. If no, the networking equipment 11 stops processing the frame; if yes, the process continues to step (306).
(306) The networking equipment 11 sends the frame to the target address through the Internet 10. If any data are sent by the networking equipment 11 to the terminal device 12 during steps (303) to (305), the networking equipment 11 will update the session data traffic in real time.
(307) The networking equipment 11 receives a confirmation message from the social networking website server 13 corresponding to the social networking website address to which the target address corresponds. Then, the networking equipment 11 completes the verification process by recording the media information on the list of verified terminal devices T1. When the terminal device 12 sends another frame to the networking equipment 11 at a later time, the networking equipment 11 will skip the determination steps described above and relay the frame instantly, allowing the terminal device 12 to connect to the network server 14 (e.g., an e-mail server, a video website server, or the like) freely through the networking equipment 11 and the Internet 10.
As the networking equipment 11 monitors the session time and session data traffic of the terminal device 12 continually while the terminal device 12 is under verification, the user of the terminal device 12 is kept from using the social networking functions of the social networking website server 13 (which is intended for verification in the first place) indefinitely without performing the required verification process after the terminal device 12 is connected to the social networking website server 13 through the networking equipment 11. This ensures that the networking equipment 11 will not provide network services to the user of the terminal device 12 without collecting the latter user's personal data in return, and the verification flaw of the prior art is thus prevented. Instead of determining “whether a frame is intended for verification”, the method of the present invention limits the networking functions according to the “session time” and the “session data traffic” and is therefore easy to perform and effective in controlling the networking functions of an “unverified terminal device 12” as a way to protect the networking equipment 11 from overloading.
It should be pointed out that the networking equipment 11 in this embodiment does not determine whether the target address of the frame corresponds to any social networking website address in the walled garden T3 until it is determined that the session time does not exceed the upper limit of time V1 and that the session data traffic does not exceed the data traffic quota V2. In practice, however, the three determination steps (303) to (305) may be carried out in an arbitrary order. In other words, the networking equipment 11 may determine whether the target address of the frame corresponds to any social networking website address in the walled garden T3 before comparing the session time and the session data traffic with their respective criteria. In any case, the networking equipment 11 sends the frame to the target address only when the requirements of all the three determination steps are satisfied.
In this embodiment, referring back to
Continued from above, the networking equipment 11 may store a plurality of upper limits of time V1 and a plurality of data traffic quotas V2 that correspond to the social networking website addresses of the plural social networking website servers 13 respectively. For example, the upper limit of time V1 and the data traffic quota V2 are “5 minutes and 15 MB” when the verification process is performed through Facebook, and “2 minutes and 12 MB” when the verification process is performed through Plurk. After receiving the request of the terminal device 12, the networking equipment 11 finds the upper limit of time V1 and the data traffic quota V2 corresponding to the social networking website address in the request in order to carry out the various determination steps in the verification process and thereby precisely control the networking functions to be allocated to the terminal device 12.
To better prevent the aforesaid flaw of the verification process, step (305) may include the networking equipment 11 directly discarding the frame upon determining that the target address of the frame does not correspond to any social networking website address in the walled garden T3. After discarding the frame, the networking equipment 11 may further find from the walled garden T3 the social networking website address of the social networking website server 13 through which the user of the terminal device 12 chose to verify the terminal device 12 at the very beginning (e.g., to verify through Facebook). Then, the networking equipment 11 obtains a verification page from the social networking website server 13 and sends the verification page to the terminal device 12. If the user of the terminal device 12 tries to use other networking functions (e.g., connecting to a video website) than the verification function before the required verification process is completed, the networking equipment 11 will ignore any such request and redirect the terminal device 12 to the verification page provided by the foregoing social networking website server 13 instead (e.g., display the login page of Facebook).
While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
