and carrying out user analysis on the user code to obtain a mobile phone number corresponding to the user code.
In detail, the request types include: a login permission request, a register account request, an unsubscribe request, etc.
Further, the preset mobile phone number library is a number record of a target company for an existing user, for example: the mobile phone number collection of registered users of a certain target company and the mobile phone number collection of consumed users of a certain target company.
In detail, the preset mobile phone number library may also be used for storing the mobile phone number of the user by a certain target company according to different service types, for example: a company has a new user mobile phone number library and a consumed mobile phone number library, and the preset mobile phone number library may also be used by a target company to store the mobile phone number of a user according to a time type, for example: a user in one mobile phone number library within one year, a user in two years, and a user in more than three years are in one mobile phone number library; the retrieval in a preset mobile phone number library according to the request type means that a certain target company classifies the mobile phone numbers of the users, and the numbers are screened in the preset mobile phone number library.
In detail, the user code refers to that the identifiers of different mobile phone numbers in the preset mobile phone number library are different, for example: the small and clear mobile phone number is represented by '1A', the preset mobile phone number library has a set of storage rules, and the request type and the user code contained in the mobile phone number can be converted by using the storage rules.
In detail, since the registered user cannot exist in the consumed user, the retrieval is performed in a preset mobile phone number library according to the request type, which is beneficial to accelerating the acquisition of the user code and improving the retrieval speed of the user code.
And S2, giving multi-channel verification authority to the terminal according to the mobile phone number and a preset encryption algorithm to obtain the number verification authority of the terminal.
In the embodiment of the invention, the multi-channel verification authority is given to the terminal so as to determine the authority of the terminal, wherein the multi-channel verification is used for being beneficial to improving the verification accuracy and preventing the omission of the authority compared with the common single verification.

In detail, the verification channel refers to the strength of the authority acquired by the mobile phone number, and the authority white list is all authority forms that the mobile phone number can have.
In detail, the preset encryption algorithm is an algorithm for giving authority to the mobile phone number, that is, the authority on the authority white list can be changed into a unique identifier readable by a computer through the path algorithm, the unique identifier is an authority key of the available authority, and the available authority can be generated from the authority key through an inverse operation of the preset encryption algorithm, that is, the authority key and the available authority are in a one-to-one correspondence relationship, and the two form a relationship through the preset encryption algorithm.
Further, the reason why the terminal is configured with the authority according to the authority key is that the available authority represented by the authority key is uniquely determined, and the number verification authority of the terminal can be generated through the authority key.
In this embodiment of the present invention, the encrypting the available permission on the permission white list based on a preset encryption algorithm to obtain the permission key of the available permission includes:

wherein, a 1 ，a 2 ，a 3 ，a 4 ，a 4 Is a constant in a finite field, x is an independent variable, and y is a dependent variable.
In detail, the preset encryption algorithm may be an elliptic encryption algorithm, which is a public key encryption system and is a calculation difficulty of forming an elliptic discrete logarithm on an Abel addition group by using rational points on an elliptic curve, and has a major advantage that it uses a smaller key than other methods in some cases, for example: another advantage of elliptical encryption algorithms, which provide a comparable or higher level of security than RSA encryption algorithms, is that bilinear mappings between groups can be defined.
In detail, the private key is the number of the base point with the order, and the private key is one key applied to an asymmetric encryption algorithm and is matched with another key for encryption and decryption, which is called a public key. Each key performs a one-way processing of the data, the function of each being exactly the opposite of the other, one for encryption, the other for decryption, the public key being made public by its owner, while the private key must be kept secret, when a secret message is sent, the sender must encrypt the data using the public key of the recipient, and once encrypted, only the recipient can decrypt it using its private key.

In detail, the preset interface identifier is used to determine whether the short message can pass through an interface, for example: the feasibility filtering may be filtering of spam messages, that is, messages added to the blacklist by the user cannot identify the preset interface identifier, and thus cannot pass the feasibility verification.
Further, the combined filtering comprises: and domain name verification and feasibility filtering are carried out, and the combined filtering can ensure that the target short message is the short message required by the user, so that the short message screening accuracy is improved.
In detail, the time configuration of the secondary short message is to verify the effective time of the short message subsequently.
And S4, carrying out validity screening on the target short message according to a preset time interval to obtain a valid short message of the target short message.
