Description
Technical Field
The invention relates to the technical field of privacy communication, in particular to a USSD and two-dimensional code-based customized protection method for the safety and privacy of a user mobile phone.
Background
In the era of mobile internet, with the rapid development of electronic commerce, mobile phone numbers are more and more popular as a trade identity identifier. Unlike the prior art that the mobile phone number only flows between friends and colleagues, the mobile phone number in the electronic commerce needs to be provided for unfamiliar strangers, and the user does not have any knowledge about the strangers who can contact the mobile phone number of the user, so that the user has a great concern about exposing the mobile phone number to other people.
In fact, cases caused by exposure of personal mobile phone numbers are actually reported, and the following are two main types of influences; 1) exposure of sensitive information: because of the online shopping requirement, the information such as the name, the address, the mobile phone number, the Email mailbox and the like of the user is continuously exposed to the network shop, the express company and other third-party organizations, so that the original online shopping protective measures based on the information such as the name, the identification card number, the mobile phone number and the like of the user are weakened, and the potential safety hazard is greatly increased; 2) frequent information disturbance: with the increase of the online shopping times of the users, more and more shops, express delivery and third-party institutions grasp the communication contact way of the users for online shopping, and the users are bombarded with sales promotion information such as telephone calls, short messages, e-mails and the like, so that the daily work and life of the users are seriously affected.
The pain point of the user needs to be solved urgently:
1) individual user pain spots (sensitive information exposure, frequent information disturbance): because of business needs, information such as user mobile phone numbers and the like is continuously exposed to network shops, express companies and other various occasions, and potential safety hazards are greatly increased. As the number of electronic transactions of the user increases, the harassment of the user by calls and short messages increases day by day, and the daily work and life of the user are seriously influenced;
2) industry user pain point (protection of user privacy concerns industry development): service providers applying O2O in express industry, logistics industry and the like can master real hands of users
As personal users pay more attention to privacy, more users will avoid using O2O applications for their privacy protection. Protecting the user's real number from being leaked will become the key for the development of various O2O application services.
The chinese patent cn201711290949.x discloses a conversation method for protecting the privacy of a client, which comprises the following operation steps: the method comprises the following steps: the user A acquires a service two-dimensional code through a mobile phone verification code; step two: the service platform records the user data relation; step three: client B is in voice communication with user a. In the scheme, after the client B scans the code, the user A can be contacted by dialing the platform service number, and after the data relationship is established, the user B can contact the opposite side until the user B scans other users again and binds a new data relationship again. Thus, in actual operation, the platform service number is always occupied by the user A, and if the platform is applied to a large third-party platform, millions of platform service numbers, thousands of platform service numbers or even hundreds of millions of platform service numbers are needed; however, the number of users who carry out communication at the same time is greatly lower than that of users who want to use, so that serious communication service resource waste is caused by setting a large number of platform service numbers; moreover, as a requirement of security and privacy, the service number of the same platform used for a long time can cause invisible secondary leakage, and particularly, unnecessary troubles are caused to users who need to use the service number temporarily.

As shown in fig. 1, the method for protecting the security and privacy of the mobile phone of the user is performed according to the following steps;
step one, a called user sends a privacy protection request to a code-scanning call front desk through a client and sets a purpose prompt; the code scanning call front desk generates a two-dimensional code according to the request and based on the mobile phone number of the called user; the code scanning calling front desk forms a first mapping relation between the two-dimension code and the mobile phone number of the called user, forms a second mapping relation between the two-dimension code and the use prompting word, and stores the first mapping relation and the second mapping relation into a relational database; the code scanning calling front desk returns the two-dimensional code to the client of the called user; the called user applies the two-dimensional code as a contact way of conversation, voice or short message to a privacy protection scene. Setting effective time limits for the first mapping relation and the second mapping relation respectively; and after the effective time limit is expired, the code scanning calling front desk sends a request for removing the mapping relation to the relational database, and the relational database removes the first mapping relation and the second mapping relation. In order to repeatedly use the two-dimension code, after the effective time limit expires, the called user scans the two-dimension code expired by the called user through the client, the code scanning and calling front desk receives a reuse request, the mapping relation between the two-dimension code and the mobile phone number of the called user is regenerated, and the effective time limit of the mapping relation is reset; and the called user resets the usage prompt words through the client.
Step two, the calling user acquires the two-dimensional code of the called user, scans and identifies the two-dimensional code, and sends a URL request to a code scanning and calling front desk according to the identification result; after receiving the URL request of the mobile phone of the calling user, the code-scanning calling front desk dynamically allocates an intermediate code number for the calling user according to the home position of the called user; and the code scanning calling front platform sends a binding service request to the intermediate number platform.
Step three, the intermediate number platform generates a number binding relation based on a calling user number-intermediate number-called user number binding service request sent by a code scanning calling front; storing code number binding relation to a relation database; setting a code number binding relationship and a two-dimensional code validation time limit; the calling user number-middle code number, middle code number-called user number are relayed and linked through a telecommunication core network; and the USSD service platform pushes a text prompt message to a calling page of the called user when the speech path between the middle code number and the called user number is accessed.
And as a specific visual scene, after the intermediate number platform successfully generates a code number binding relationship and stores the code number binding relationship in a relational database, the intermediate number platform feeds back a result to a code scanning and calling front desk, and the code scanning and calling front desk sends the intermediate code number to a mobile phone interface of a calling party for display and is used for the calling party to dial.
The specific application process of the usage hint here is as follows: after receiving ringing message of called user in the telephone channel of the intermediate number-called user number, the intermediate number platform sends the ringing message to the code-scanning calling front desk; the code scanning calling front desk inquires a relational database according to the first mapping relation and the second mapping relation to obtain a purpose prompt language set by the called user; after the code scanning call foreground obtains the purpose prompting words, a user prompting word sending request is sent to the USSD service platform, wherein the user prompting word sending request comprises a target mobile phone number and a pushed text; the USSD service platform finds the position of the called user according to the mobile phone number of the called user, and pushes the user prompt text message to the front end of the calling page of the called user terminal for displaying.
Here, the specific connection process of the speech path is as follows: the calling subscriber dials the intermediate number, and the speech path roams to the intermediate number platform through the network of the marketing business; after the intermediate number platform receives a calling user request for the intermediate number speech path, the intermediate number platform searches the number binding relationship in the relational database; initiating a request of the intermediate code number to the called user telephone channel; and the intermediate number platform controls the establishment of the speech paths between the calling user number and the intermediate number and between the intermediate number and the called user number, and completes speech path connection.
And step four, after the time limit for the code number binding relationship to be effective is expired, the code number binding relationship is released, and the intermediate code number dialing is forbidden.
In order to better avoid secondary information leakage caused by the two-dimensional code, the effective time limit of the first mapping relation, the second mapping relation and the code number binding relation is related to the number of the calling party, the intermediate code number and the number of the called party, which are communicated in the third step; and after the number of the penetration times is reached, the effective time limit expires. Certainly, the first mapping relation validation time limit is not less than the code number binding relation validation time limit or the second mapping relation validation time limit; therefore, the service cycle of the two-dimensional code can be guaranteed, and the conversation safety and privacy are protected.
Compared with the prior art, the invention can realize dynamic allocation of the intermediate code number, realize the requirement that hundreds of intermediate code numbers can serve tens of thousands of users, greatly reduce the stock of the intermediate code number and improve the utilization rate; meanwhile, the effective time limit of the mapping relation and the code number binding relation is set, so that secondary information leakage cannot be caused when the contact information is transmitted by using the two-dimensional code, namely the intermediate code number is used as a mobile phone connecting channel for a long time, and the requirement of seeking mobile phone safety and privacy protection in a short time range is not facilitated. The effective time limit is set to the mapping relation and the code number binding relation, so that the intermediate code number is not in the time limit for dialing the called user for a long time, the two-dimensional codes which are not used are invalid in sequence, the two-dimensional codes can be used for a poor time limit but have a time limit for each call, the requirement that the two-dimensional codes are scanned for multiple times in a certain period is met, and the call time for each dialing is limited. Therefore, compared with the prior art, the invention is dynamic, the intermediate code number is also dynamically distributed, and different intermediate code numbers can be used for each call, so that the effect of safety and privacy protection is greatly enhanced.
