The original communication number, the verification code corresponding to the original communication number and the new communication number are indispensable items. And developing the preset replacement platform according to the collected verification information required to be input by replacing the communication number of all the application programs. It should be noted that all the applications mentioned in this application do not really refer to all the applications existing in the market, but refer to applications that may have mobile phone number bindings or applications that have higher usage rate and mobile phone number bindings. Through the preset replacement platform, the communication numbers can be replaced uniformly and safely, and users only need to operate once on the preset replacement platform to input verification information, so that all application programs can complete the updating of the communication numbers.

It is noted that the default replacement platform may be present in the form of a module, e.g. present in a certain application program of interest, or it may be understood that the default replacement platform is part of a certain application program. In some cases, the preset replacement platform may exist in the form of an APP, for example, the APP may operate independently, or may also exist in the form of an applet (an applet corresponding to the preset replacement platform may be called by other applications).

Fig. 1 is a timing diagram illustrating a method for replacing a communication number according to an embodiment of the present application. As shown in fig. 1, the method comprises the following steps S101-S109. Steps S101 to S103, S109 are executed on the server side of the preset replacement platform, and steps S104 to S108 are executed on the server side of the target application program.

S101, a server side of a preset replacement platform receives and stores a number replacement request input by a user through a client side of the preset replacement platform, wherein the number replacement request comprises original communication numbers bound by all application programs on the client side, new communication numbers needing to be bound again and verification information needed for binding change.

It can be understood that, the user inputs all verification information, original communication numbers, new communication numbers and the like of the communication numbers of all the applications on the replacement client at one time through the client of the preset replacement platform. The input verification information comprises a verification code corresponding to the original telephone. Specifically, the method comprises the following steps: if a verification code acquisition instruction of a user is received, acquiring an original communication number input by the user through a client of a preset replacement platform; generating a verification code; sending the generated verification code to the client through the acquired original communication number; if receiving a submission instruction of a user, verifying whether the verification code input by the user in the submission instruction is consistent with the generated verification code and whether the verification code is valid; if the verification codes are consistent and valid, receiving verification information input by a user in the submitted instruction, and storing the received verification information; otherwise, the user is prompted to re-enter.

And S102, the server side of the preset replacement platform inquires an application program matched with the original communication number in a database of the preset replacement platform as a target application program according to the original communication number in the number replacement request.

It should be noted that the database of the server of the default replacement platform stores various applications bound to the communication numbers. The preset manner for the server of the replacement platform to obtain the various applications bound to the communication number may include the following manners. When a user uses a certain application program and needs to bind or input a communication number, after the server of the application program receives the communication number bound or input by the user, the server of the application program simultaneously sends the communication number and the corresponding application program information to a server of a preset replacement platform, and the server of the preset replacement platform stores the communication number and the corresponding application program information; if the server of the preset replacement platform is in timing to the server side of various application programs to acquire the message of the updated communication number; for example, the server of various application programs actively sends the updated communication number message to the server of the preset replacement platform at regular time. In this embodiment, a manner in which the server side of the preset replacement platform acquires the various applications bound to the communication number is not limited, as long as the preset replacement platform stores the communication number and information of the various applications bound to the communication number.

And the server side of the preset replacement platform inquires the matched application program bound with the original communication number in a database of the preset replacement platform according to the original communication number in the received number replacement request, and takes the inquired matched application program as a target application program. Namely, the application program with the binding relation existing in the inquired original communication number is determined as the target application program.

And S103, the server side of the preset replacing platform sends the number replacing request to the server side of the target application program so that the server side of the target application program replaces the original communication number with the new communication number according to the verification message.

In one embodiment, step S103 includes: and the server side of the preset replacement platform acquires the verification information corresponding to each target application program from the verification information according to the target application program, and sends a number replacement request comprising the verification information corresponding to the target application program to the server side of each target application program so that the server side of the target application program replaces the original communication number with the new communication number according to the verification information corresponding to the target application program, wherein the number replacement request does not comprise the verification information required by the change and the binding of all the application programs but comprises the verification information corresponding to each target application program. In this embodiment, the preset database at the server side of the replacement platform stores the types of the authentication information corresponding to each application program, such as one or more of a mailbox, an identity card, a fingerprint, a voiceprint, a face image, a gesture password, and a video with predetermined requirements. Acquiring the type of the verification information corresponding to each target application program from a database; acquiring the verification information corresponding to each target application program from the verification information (the verification information required by all application program change binding) according to the type of the verification information corresponding to each target application program; and sending the number replacement request to the server side of each target application program so that the server side of each target application program replaces the original communication number with a new communication number according to the corresponding verification information. The authentication information may vary from target application to target application. It can be understood that, if the type of the verification information required for changing the binding corresponding to the target application program a includes a face image, the verification information in the number replacement request sent to the target application program a includes the face image; and if the verification information type required by the binding change corresponding to the target application program B comprises the voiceprint, the verification information in the number replacement request sent to the target application program B comprises the voiceprint. In this embodiment, the server on the preset replacement platform automatically distributes the received verification information required for binding change of all the application programs to each target application program, and replaces the communication number according to the verification information corresponding to each target application program.

In one embodiment, step S103 includes: and sending the number replacement request to a server side of the target application program, so that the server side of the target application program extracts verification information corresponding to the target application program according to the verification information, and replaces the original communication number with the new communication number according to the verification information corresponding to the target application program. In this embodiment, the verification message sent to the server side of each target application includes verification information required for changing the binding of all applications, and thus, after the target application receives the verification information required for changing the binding of all applications, the verification information corresponding to each target application is obtained from the verification information required for changing the binding of all applications according to the verification information pre-stored in the database of the target application, and the communication number is changed according to the verification information corresponding to each target application. In this embodiment, after receiving the verification information required by all the application program change bindings, the target application program automatically obtains the verification information corresponding to the target application program from the verification information.

And sending the number replacement request to a server corresponding to the target application program. If there are a plurality of target applications, the target applications may be sent to a plurality of servers of the target applications at the same time, or may be sent to the servers of the target applications one by one.

And S104, the server side of the target application program receives the number replacement request.

And S105, the server side of the target application program extracts the original communication number, the new communication number and the verification information corresponding to the target application program in the number replacement request. The verification information corresponding to the target application program includes other verification information except the verification code, such as one or more of a mailbox, identification card information (including an identification card picture and an identification card number), a fingerprint, a voiceprint, a face image, a gesture password, a video with a predetermined requirement, and the like. If a certain target application program only changes the communication number according to the verification code, the verification information corresponding to the target application program is null.

If the verification information required for modifying and binding all the application programs is automatically allocated, that is, the verification information in the number change request includes the verification information corresponding to the target application program, in this step, "the server of the target application program extracts the original communication number, the new communication number and the verification information corresponding to the target application program" in the number change request, that is, "the server of the target application program obtains the original communication number, the new communication number and the verification information corresponding to the target application program".

If the verification information required for changing and binding all the application programs is not processed, that is, the verification information in the number change request includes the verification information required for changing and binding all the application programs, in this step, "the server side of the target application program extracts the original communication number, the new communication number and the verification information corresponding to the target application program in the number change request", which is understood to be that the verification information corresponding to the target application program is automatically extracted from the verification information required for changing and binding all the application programs. In this way, the server side of the target application program extracts the original communication number, the new communication number and the verification information corresponding to the target application program in the number replacement request.

S106, searching the verification information prestored in the original communication number according to the extracted original communication number, and judging whether the extracted verification information corresponding to the target application program is consistent with the verification information prestored in the original communication number.

Specifically, according to the extracted original communication number, inquiring verification information prestored in the original communication number in a database of a target application program; matching the extracted verification information corresponding to the target application program with the verification information prestored in the original communication number; and judging whether the extracted verification information corresponding to the target application program is consistent with the prestored verification information corresponding to the original communication number.

And S107, if the verification information corresponding to the target application program is consistent with the pre-stored verification information corresponding to the original communication number, replacing the original communication number in the target application program with a new communication number.

It should be noted that, if the verification information corresponding to the target application program is empty and the verification information prestored in the original communication number does not exist, it is determined that the verification information corresponding to the target application program is consistent with the prestored verification information. It can be understood that when many application programs change the telephone number, only the original communication number (some of the communication numbers also include verification codes and the like) and the new communication number need to be input, and thus, corresponding verification information does not exist.

The method comprises the steps of replacing an original communication number in a target application program with a new communication number, and the steps of unbinding the original communication number and binding the new communication number.

And S108, after the replacement is finished, sending a message of successful replacement to a server of a preset replacement platform, and if the verification information corresponding to the target application program is inconsistent with the pre-stored verification information corresponding to the original communication number, sending a message of failed replacement to the server of the preset replacement platform.

If the original communication number in the target application program is successfully replaced with the new communication number, namely the replacement is successful, the server side of the target application program sends a message of successful replacement to a server of a preset replacement platform, and if the verification information corresponding to the target application program is inconsistent with the pre-stored verification information corresponding to the original communication number, a message of failed replacement is sent to the server of the preset replacement platform. If the corresponding verification information is inconsistent with the pre-stored verification information, the operation of the user is not considered.

And S109, receiving a message of successful or failed replacement returned by the server of the target application program by the server of the preset replacement platform.

Therefore, the messages of successful replacement and identification of replacement received by the server end can be displayed on the client end of the preset replacement platform, so that a user can conveniently know which application programs are successful in replacing the communication numbers and which application programs are failed in replacement.

In an embodiment, before the step of replacing the original communication number in the target application program with a new communication number, the server side of the target application program further executes the steps of: sending confirmation information of replacing the communication number to a client corresponding to the original communication number; and if the confirmation information sent by the client corresponding to the original communication number is received, replacing the original communication number in the target application program with a new communication number. Thus, it is further ensured whether the communication number is to be replaced by the user, and the security of replacing the communication number is improved.

In an embodiment, after the original communication number of the target application is replaced with a new communication number, the server side of the target application further performs the following steps: and sending the replaced new communication number and application program information (which can be application identification information and the like so as to be convenient for the server side of the preset replacement platform to identify) corresponding to the target application program to a server of the preset replacement platform, so that the server of the preset replacement platform stores the replaced new communication number to update the information in the database. Therefore, the data in the database of the preset replacement platform is updated in real time.

In the embodiment, the original communication numbers which are bound by all the application programs and input by the client of the preset replacement platform, the new communication numbers which need to be bound again and the verification information needed for changing the binding are received, and all the target application programs matched with the original communication numbers are inquired in the database according to the original communication numbers, so that all the target application programs replace the original communication numbers with the new communication numbers in the verification information. Therefore, the server of the preset replacement platform automatically performs communication number replacement on each target application program by inputting the verification information of all the application programs at one time. The communication numbers of the target application programs can be modified at one time, the efficiency of replacing the communication numbers is improved, the problem that the communication numbers cannot be replaced due to the fact that the communication numbers of one part of the application programs are not replaced in time while the communication numbers of the other part of the application programs are not replaced in time is solved, and user experience is improved.

Fig. 2 is a timing diagram illustrating a method for changing a communication number according to another embodiment of the present application. As shown in fig. 2, the method comprises the following steps S201-S213. Steps S201 to S204, S206 to S207, and S213 run on the server side of the preset replacement platform, and steps S205 and S208 to S212 run on the server side of the target application program.

S201, a server side of a preset replacement platform receives and stores a number replacement request input by a user through a client side of the preset replacement platform, wherein the number replacement request comprises original communication numbers bound by all application programs on the client side, new communication numbers needing to be bound again and verification information needed for binding change.

S202, the server side of the preset replacement platform inquires an application program matched with the original communication number in a database of the preset replacement platform as a target application program according to the original communication number in the number replacement request.

S203, the server side of the preset replacement platform generates a pair of public key and private key through an asymmetric encryption algorithm.

The asymmetric encryption algorithm generates a pair of secret keys, namely a public key and a private key, in the using process, the public key is used for encryption, and the private key is used for decryption. Asymmetric algorithms such as the RSA algorithm. It should be noted that the pair of public and private keys generated are different for different target applications.

And S204, the server side of the preset replacement platform sends the generated private key to the server side of the target application program.

S205, the server side of the target application program receives a private key sent by a server of a preset replacement platform.

And S206, the server side of the preset replacing platform encrypts the number replacing request by using the generated public key to obtain first encrypted data.

In one embodiment, the steps include: and the server side of the preset replacement platform acquires the verification information corresponding to each target application program from the verification information required by the change and binding of all the application programs in the number replacement request according to the target application program, and encrypts the number replacement request comprising the verification information corresponding to the target application program by using the generated public key to obtain first encrypted data, wherein the number replacement request is not the verification information required by the change and binding of all the application programs but the verification information corresponding to each target application program. In this embodiment, the authentication information required for all the applications to change the binding is automatically allocated, so that the data before encryption corresponding to each target application may be different.

In an embodiment, the verification information in the number change request in this step is the verification information required by all the applications to change the binding, so that the data before encryption corresponding to each target application is identical.

And S207, the server side of the preset replacement platform sends the first encrypted data to the server side of the target application program.

S208, the server side of the target application program receives first encrypted data sent by a server of a preset replacement platform.

S209, the server side of the target application decrypts the first encrypted data by using the private key to obtain the original communication number, the new communication number, and the verification information corresponding to the target application.

If the verification information required by the binding change of all the application programs is automatically distributed, namely the verification information in the number change request only comprises the verification information corresponding to the target application program, the server side of the target application program can directly obtain the original communication number, the new communication number and the verification information corresponding to the target application program after decrypting the first encrypted data by using the private key.

If the verification information required for changing and binding all the application programs is not processed, that is, the verification information in the number change request includes the verification information required for changing and binding all the application programs, after the server side of the target application program decrypts the first encrypted data by using the private key, the verification information corresponding to the target application program needs to be automatically extracted from the decrypted data. Thus, the original communication number, the new communication number and the verification information corresponding to the target application program are obtained.

Since the server side of the target application program has correct private key data, only the correct private key can decrypt the first encrypted data encrypted by the public key of the key pair. And if the other terminals do not have the private key, the first encrypted data cannot be decrypted. And the safety of the information is ensured by using the key pair. Such as at least securing the authentication information transfer process.

S212, after the replacement is finished, a message of successful replacement is sent to the server of the preset replacement platform, and if the pre-stored verification information is inconsistent with the verification information obtained by decryption, a message of failed replacement is sent to the server of the preset replacement platform.

If the pre-stored verification information is inconsistent with the verification information obtained by decryption, the operation is not the operation of the user or the operation of the user, and the corresponding verification information is subjected to conditions such as modification or inaccurate verification information input in the transmission process. For security reasons, the communication number is not replaced.

S213, receiving the message of successful or failed replacement returned by the server of the target application program.

It should be noted that, in this embodiment, the same steps or the same noun descriptions as those in the embodiment of fig. 1 are referred to the corresponding descriptions in the embodiment of fig. 1, and are not repeated herein.

The original communication number, the new communication number, the verification information corresponding to the target application program and the like are relatively private data. Therefore, the embodiment encrypts the number verification request (the number verification request comprises the original communication number, the new communication number, the verification information corresponding to the target application program and the like) by using the asymmetric encryption algorithm, so that the safety of the verification information is ensured, and the safety of information transmission is improved.

Fig. 3 is a timing diagram illustrating a method for changing a communication number according to another embodiment of the present application. As shown in fig. 3, the method comprises the following steps S301-S317. Steps S301 to S305, S310 to S311, and S317 are executed on the server side of the preset replacement platform, and steps S306 to S309, and S312 to S316 are executed on the server side of the target application.

S301, a server side of a preset replacement platform receives and stores a number replacement request input by a user through a client side of the preset replacement platform, wherein the number replacement request comprises original communication numbers bound by all application programs on the client side, new communication numbers needing to be bound again and verification information needed for binding change.

And S303, generating a pair of public key and private key by the server side of the preset replacement platform through an asymmetric encryption algorithm.

S304, the server side of the preset replacement platform encrypts the identification information of the target application program through a message digest algorithm to obtain second encrypted data.

And the database of the preset replacement platform stores the identification information of the target application program corresponding to the original communication number. Identification information refers to information that can identify an application. The main characteristic of the message digest algorithm is that no key is needed in the encryption process, the encrypted data cannot be decrypted, and the same ciphertext (encrypted data) can be obtained only by inputting the same plaintext data (data to be encrypted) and performing the same message digest algorithm. It should be noted that different target applications correspond to different identification information, and the second encrypted data obtained by encrypting the corresponding identification information by the different target applications are different.

It should be noted that the order of step S303 and step S304 is not limited strictly, and in other embodiments, step S304 may be executed first, and step S303 may be executed.

S305, the generated private key and the generated second encrypted data are sent to the server side of the target application program.

S306, the server side of the target application program receives the private key and the second encrypted data sent by the server of the preset replacing platform.

Data generated according to a message digest algorithm is hardly or cannot be decrypted. The third encrypted data is generated by the server side of the target application program according to the same message digest algorithm, and the second encrypted data is generated and sent by the server side of the preset replacement platform. If the second encrypted data is consistent with the third encrypted data, the identification information of the application program is consistent with the identification information stored in the preset replacement platform, and meanwhile, the network is relatively safe, and at least the second encrypted data is completely safe.
