Fig. 1 is a flowchart of an identity authentication method based on a mobile phone number in an embodiment of the present application. The identity authentication method based on the mobile phone number can be applied to the scene that a user account logs in an application program, and can be realized on terminal equipment such as a mobile phone, a tablet, wearable equipment and the like. As shown in fig. 1, the identity authentication method based on the mobile phone number includes the following steps:
s10: the mobile terminal acquires the mobile phone number input by the user.
In an embodiment, when a user logs in a user account (especially, a first login scenario) in an application program, user identity authentication can be achieved by inputting a mobile phone number, so that the purpose of logging in the application program is achieved. Specifically, the mobile terminal may provide a text filling box on the display interface, and the user inputs the mobile phone number through the text filling box. Further, if the desensitization mobile phone number is stored in the mobile terminal, the known mobile phone number part can be displayed in a text filling box, and the user only needs to fill the mobile phone number of the desensitization part. The mobile terminal can not store the plaintext mobile phone number of the user locally, only part of the mobile phone number is input when the input of the mobile phone number of the user is finished, and the mobile phone number of the user can be well protected.
S20: and the mobile terminal carries out desensitization processing on the mobile phone number to obtain the desensitization mobile phone number.
Wherein the desensitization treatment may be pre-set. For example, the last four digits of the mobile phone number or the middle four digits of the mobile phone number are replaced by the good word, so that the effect of desensitizing the mobile phone number is achieved. By adopting the mobile phone number desensitization processing, the mobile phone number is not stored in the mobile equipment in a plaintext form all the time, and other equipment cannot directly acquire the plaintext mobile phone number from the mobile equipment, so that the confidentiality of the mobile phone number of the user can be improved.
S30: the mobile terminal sends a first request to the application server, wherein the first request is used for acquiring a first segment key.
In an embodiment, when the mobile terminal and the application server interact, the desensitization mobile phone number can be encrypted, so that the login security of the application program can be further improved. Specifically, the mobile terminal requests the application server to acquire the first segment key. The first segment key is distributed to the application server in advance. The concept corresponding to the first segment key is a second segment key, the second segment key and the first segment key are used for obtaining a new key after combination, and the desensitization mobile phone number is encrypted and decrypted by using the new key.
It is understood that the current encryption method generally assigns the same key to both the mobile terminal and the application server for encryption and decryption of data, and in the embodiment of the present application, the keys assigned to the mobile terminal and the application server are different from each other. The storage mode of the multi-section secret key can improve the transmission security of interaction data such as desensitization mobile phone numbers, and even if the section secret key of one of the mobile terminal or the application server is leaked, other equipment cannot decrypt the data encrypted by the first section secret key and the second section secret key of the encryption desensitization mobile phone numbers.
S40: the application server receives a first request sent by the mobile terminal, and sends a first segment key to the mobile terminal according to the first request.
In an embodiment, when the mobile terminal needs to encrypt data such as desensitized mobile phone number, the encryption cannot be completed only by the second segment key of the mobile terminal. After receiving the first request, the application program sends the first segment key to the mobile terminal, so that the mobile terminal can complete encryption of data such as a desensitized mobile phone number according to the first segment key and the second segment key.
S50: the mobile terminal receives a first segment key sent by the application server, and combines the first segment key with a second segment key by adopting a preset key combination algorithm to obtain an encryption and decryption key, wherein the second segment key is stored in the mobile terminal.
In an embodiment, the encryption and decryption keys are symmetric keys, that is, the same key is used for encryption and decryption. And the mobile terminal acquires the first segmented key and then combines the first segmented key with a second segmented key stored locally according to a key combination algorithm to obtain an encryption and decryption key. The key combination algorithm is predetermined by the mobile terminal and the application server, and the two parties use the same key combination algorithm, so that when the mobile terminal and the application server have encryption or decryption requirements, a segmented key stored by the other party and a local segmented key combination can be obtained, and data such as desensitized mobile phone numbers and the like are encrypted or decrypted after the encryption and decryption keys are obtained. Compared with the traditional encryption and decryption mode, the encryption and decryption key obtained by the mode is associated with the mobile terminal and the application server, and even if the segmented key in the mobile terminal or the application server is leaked, the mobile phone number of the user cannot be leaked. If the traditional mode is adopted, the mobile terminal and the application server respectively store the symmetric keys which can be directly used for encryption and decryption, and after the symmetric key of one party is leaked, the mobile phone number of the user is also cracked. The method and the device for encrypting the mobile phone number in the segmented mode can well improve the protection of the mobile phone number of the user.
S60: the mobile terminal encrypts the desensitization mobile phone number by adopting the encryption and decryption key to obtain the encryption desensitization mobile phone number.
In one embodiment, the encryption desensitization mobile phone number is obtained by encrypting with an encryption and decryption key. On the side of the application server, the desensitization mobile phone number can be obtained after the encryption and decryption key is used for decrypting the encrypted desensitization mobile phone number.
S70: and the mobile terminal sends the second segment key and the encryption desensitization mobile phone number to the application server according to the acquired mobile phone number calling instruction.
The mobile phone number calling instruction refers to an instruction related to calling a mobile phone number of a user. If the application program login identity authentication is completed, the user account needs to call the mobile phone number when logging in, and the user can trigger a mobile phone number calling instruction through login operation. It can be understood that the mobile terminal does not locally store a plaintext mobile phone number, and the calling of the mobile phone number in this embodiment refers to calling of an encryption desensitized mobile phone number. Correspondingly, in order that the application server can decrypt the encryption desensitization mobile phone number sent by the mobile terminal, the mobile terminal correspondingly sends a second segment key stored locally when sending the encryption desensitization mobile phone number, so that the authentication of application program login is completed according to the desensitization mobile phone number obtained after decryption.
S80: and the application server receives the second segment key and the encryption desensitization mobile phone number sent by the mobile terminal.
S90: and the application server combines the second section key and the first section key by adopting a preset key combination algorithm to obtain an encryption and decryption key.
In an embodiment, the application server uses a key combination algorithm the same as that of the mobile terminal to combine the received second segment key with the first segment key locally stored by the application server, so as to obtain the encryption and decryption key. It can be understood that the generation of the encryption and decryption key is combined with the second segment key at the mobile terminal side, so that the acquisition of the encryption and decryption key is associated with the mobile terminal and the application server, and both of them need to complete the encryption and decryption of data under the cooperation of the other. In the embodiment of the application, the mode that the encryption and decryption keys are generated by combining the mobile terminal and the application server together provides a good safe environment for the transmitted desensitized mobile phone number, and the privacy protection on the user plaintext mobile phone number can be further improved by desensitizing and encrypting.
S100: the application server decrypts the encrypted desensitized mobile phone number by adopting the encryption and decryption key to obtain the desensitized mobile phone number.
S110: and the application server completes identity authentication according to the desensitization mobile phone number.
In an embodiment, the application server obtains the desensitization mobile phone number sent by the mobile terminal, and the identity authentication can be directly completed by using the desensitization mobile phone number according to an identity authentication scene, such as an identity authentication scene in which an application program initially logs in, the application program logs in, and the application program logs in but does not currently log in, or the identity authentication can be completed by obtaining a plaintext mobile phone number from the application server through the desensitization mobile phone number.
In the embodiment of the application, a first segment key and a second segment key are set in the application server and the mobile terminal by adopting a segment encryption mode. When the identity authentication based on the mobile phone number is carried out, the interaction of the mobile terminal and the application server is utilized, so that the first segment key and the second segment key are combined to obtain the encryption and decryption key in the interaction process, the encryption of the desensitization mobile phone number by the mobile terminal is completed by the encryption and decryption key, and the encryption and desensitization mobile phone number is decrypted by the application server. When the user completes the identity verification of the application program, the mobile terminal side can avoid the plaintext mobile phone number, and even if the data is intercepted, the plaintext mobile phone number cannot be obtained through decryption from the data. According to the method and the device, the security of personal hiding of the user can be improved when the identity authentication of the application program is completed based on the mobile phone number.
Further, before step S10, that is, before the mobile phone number input by the user is acquired, the method for authenticating an identity based on a mobile phone number further includes the following steps:
s11: the mobile terminal generates an encryption and decryption key.
In one embodiment, the encryption and decryption keys may be pre-generated. The encryption and decryption keys are symmetric keys and are randomly generated according to different time periods. It can be understood that the encryption and decryption keys are not fixed and can be set to change along with the change of time, so that a plurality of different encryption and decryption keys are allowed to exist, and thus, the protection of the mobile phone number of the user can be further improved.
S12: the mobile terminal divides the encryption and decryption key into a first section key and a second section key by adopting a preset key section algorithm, wherein the preset key combination algorithm is determined according to the preset key section algorithm.
In one embodiment, the predetermined key combination algorithm corresponds to a predetermined key segmentation algorithm. The key segmentation algorithm is determined first, and then the key combination algorithm is determined according to the key segmentation algorithm. It is to be understood that when it is set how to divide the encryption/decryption key into the first segment key and the second segment key, a key combination algorithm for combining the first segment key and the second segment key into the encryption/decryption key may be determined accordingly.
S13: the mobile terminal sends the generation time of the encryption and decryption key, the generation device identification and the first segment key to the application server.
The generation device identifier is an identifier that uniquely identifies a device that generates the encryption/decryption key.
In one embodiment, the encryption and decryption keys are associated with a generation time and a generation device identification. After the mobile terminal sends the first segment key, the generation time of the encryption and decryption keys and the generated equipment identification to the application server, when the transmitted data needs to be encrypted and decrypted subsequently, the corresponding first segment key can be determined according to the generation time of the decryption keys and the displacement of the generated equipment identification, so that the encryption and decryption keys can be obtained by changeably and accurately combining the first segment key and the second segment key locally stored by the mobile terminal, and the encryption and decryption of the data such as the encryption desensitization mobile phone number and the like can be completed by adopting a plurality of different encryption and decryption keys.
Further, the above process of generating the encryption and decryption keys may also be implemented by the application server side, which is not limited herein, as long as both the application server and the mobile terminal determine the distribution of the first segment key and the second segment key.
Further, in step S10, sending the first request to the application server specifically includes the following steps:
the mobile terminal sends a first request comprising the generation time of the encryption and decryption key and the generation equipment identification to the application server, so that the application server determines a preset key combination algorithm and a first segment key according to the generation time of the encryption and decryption key and the generation equipment identification.
In an embodiment, the first request includes a generation time of the encryption and decryption key, a generated device identifier, and the application server may determine a first segment key corresponding to the generation time and the generated device identifier, and a corresponding preset key combination algorithm. It can be understood that this manner can support multi-key management, and the mobile terminal determines that the second segment key includes the generation time and the generation device identifier of the encryption and decryption key corresponding thereto, so that the corresponding encryption and decryption key can be generated by selecting the first segment key corresponding to the second segment key one to one and the preset key combination algorithm. By adopting the key management mode, even if the second section key of the mobile terminal and the first section key of the application server are leaked at the same time, the corresponding encryption and decryption keys cannot be obtained because the corresponding relation between the first section key and the second section key and the preset key combination algorithm is uncertain.
In the embodiment of the application, the generation of the encryption and decryption keys is associated with the generation time and the generation equipment identification, and the situation that a plurality of encryption and decryption keys exist simultaneously is supported. The encryption and decryption keys are generated into the corresponding first segment key and the second segment key by adopting a preset segment key segmentation algorithm, so that the mobile terminal and the application server can respectively store the segment keys for generating the encryption and decryption keys, and the security of data transmission such as desensitization mobile phone numbers can be improved.
Further, in step S50, combining the second segment key with a preset key combination algorithm to obtain an encryption/decryption key, specifically including the following steps:
s51: and the mobile terminal numbers the characters in the first segmented key and the characters in the second segmented key.
In one embodiment, the first segment key and the second segment key are character strings composed of characters. The characters of the first and second segment keys may be numbered separately in string order. For example, the character string of the first segment key is denoted as "shmfbnogr", then s may be denoted as [1,1], and h may be denoted as [1,2], where 1 in [1,2] denotes the first segment key and 2 denotes the occurrence position of the character in the first segment key. By analogy, the second segment key can also complete character numbering in this way.
S52; and the mobile terminal determines the combination operation of the numbered characters according to a preset key combination algorithm, and combines the first segment key and the second segment key to obtain the encryption and decryption key.
The key combination algorithm is obtained according to a key segmentation algorithm, and represents the processing of characters in the first segmentation key and the second segmentation key. Specifically, the key combination algorithm may specifically be to connect the first segment key and the second segment key (the first segment key is arranged in front), and then mutually alternate the characters with even-numbered appearance positions between the first segment key and the second segment key according to the order to obtain the encryption and decryption key. For example, if the string of the first segment key is denoted as "shmfbnogr" and the string of the second segment key is denoted as "lkdjspjno", the encryption/decryption key "skmjbponrlhdfsnjo" can be obtained according to the combination algorithm described above.
In steps S51-S52, a specific implementation manner is provided in which the first segment key and the second segment key are combined to obtain the encryption and decryption keys, and the second segment key and the first segment key are stored in the mobile terminal and the application server, respectively, so that the effect of segment encryption is achieved, and the security of personal hiding of the user can be improved when the authentication of the application program is completed based on the mobile phone number.
Further, in step S110, namely, the identity authentication is completed according to the desensitization mobile phone number, the method specifically includes the following steps:
s111: and when the mobile terminal logs in the application program and is not in the login state at present, the application server decrypts the token by adopting the encryption and decryption key to obtain the desensitization mobile phone number to be verified and the identity information to be verified.
The token is specifically a token, and is a piece of temporary information used for login authentication of a mobile terminal user account, and the token may include an encryption desensitization mobile phone number and other encrypted to-be-authenticated identity information.
In one embodiment, when the mobile terminal is in a login state, identity authentication can be directly completed through a token; when the mobile terminal logs in the application program and is not in the login state currently, the token can be used for assisting in completing identity authentication.
