Description
Technical Field
The invention relates to mobile internet authentication service, in particular to a service technical implementation scheme for confirming the ownership of a user number through voice calling.
Background
From the era of mobile internet, a mechanism for registering by using a mobile phone number as an account number is becoming popular. The reason is that the usage rate of the mobile phone is high, the number of the mobile phone is unique, and a way for the enterprise to contact the client is provided. Then, the account registration is performed using the mobile phone number, and it is necessary to determine that the mobile phone number registered by the user is the user himself at the beginning. The short message verification code can similarly determine whether the mobile phone number is owned by the user, namely, the mobile phone of the registered member receives a random verification code short message, and the user proves and determines the ownership of the mobile phone number to the service provider by inputting the content of the received verification code.
The short message verification code also highlights the following weaknesses in the increasingly popular application:
1. the plaintext transmission is intercepted and forwarded in the communication process, and the safety is lost. Along with the popularization of intelligent terminals, Trojan horses of mobile phones become rampant increasingly and are implanted into mobile phones of users through the development of fishing short messages. With the development of the black industrial chain of mobile commerce, the infection and the spread of trojans are very rapid, and the protection effect of the short message verification code on the safety is greatly weakened.
2. With the large-scale rectification treatment of the spam short messages conducted by the network side, the arrival rate and timeliness of the verification code short messages generally have certain problems; furthermore, the short message with the verification code is directly classified into a blacklist due to misjudgment of some safety software on part of the mobile phones of the users, and serious influence is caused on the service experience of the users.
3. The short message has the characteristic of single side, and a user receiving the short message cannot verify the final real source of the short message. With the excessive development of the short message marketing industry and the appearance of black industries such as pseudo base stations, number changing software and the like, a user doubts the authenticity of various short messages, and the reliability of the short messages sent by a single side is gradually reduced.
Because the existing user passive receiving type short message verification code mode has the defects, and in addition, the purpose of the verification code service is to confirm the ownership of the mobile phone number of the user, a mode of actively initiating a voice call by the user to verify the number can be designed, and the service flow is optimized to solve the problems in the development process of the user number verification service.
In order to verify the registration number provided by the user, the user to be verified can initiatively initiate a call to the number designated by the verification platform, and the verification platform judges whether the call is a real call initiated by the number to be verified through a verification algorithm so as to eliminate the possibility that the number to be verified is forged by number-changing software to initiate the call.
Chinese patent CN105915517A (a method for implementing voice verification code service) discloses a service technical implementation scheme for confirming the ownership of a user number by calling. According to the service design principle of the mobile communication network, only the international mobile subscriber identity IMSI is stored in the mobile phone SIM card, the temporary mobile subscriber identity TMSI temporarily allocated by the network corresponding to the international mobile subscriber identity IMSI is transmitted in the air interface, and the real mobile phone number is stored in the core network home location register HLR and the visitor location register VLR. The mobile phone number indicating the own identity to the opposite party by the user in the process of the external communication is added by the mobile switch after the user accesses the network. Therefore, all calls sent by the mobile network internal end office can be considered to be really dialed by the mobile phone of the user, so that the authenticity of the calling number of the user can be judged by adding the network call route analysis function in the verification process, and the complete number verification process is completed. However, this technique has disadvantages in terms of system complexity and verification accuracy in practical applications. Firstly, a method for analyzing and judging the media surface IP address of a calling side needs to introduce a signaling monitoring subsystem in a technical implementation scheme and acquire related calling signaling in a bypass mode, so that the complexity of the system is greatly increased; in addition, because the capacity expansion or adjustment of the device is frequent in the communication network, the change of the corresponding media side IP address of the calling side is also frequent, and if the corresponding whole network IP address table as the basis for judgment is not updated in time, the result accuracy of number verification is greatly influenced.
