Embodiment Construction

[0062] Such as figure 1 As shown, an improved encryption method based on comprehensive identification includes the following steps:

[0063] S1. Pre-store the decryption information of the mobile terminal, the decryption information includes the voiceprint information, fingerprint information and password information of the legal user; set the decryption authority weight of each decryption information and the decryption information combination.

[0064] Optionally,

[0065] In the step S1:

[0066] The decryption authority weights of each decryption information and combination of decryption information are as follows: the weight of voiceprint information is 1.5, the weight of fingerprint information is 1.5, the weight of password information is 1, and the weight of combination of voiceprint information and fingerprint information is 3. The weight of the combination of voiceprint information and password information is 2.5, the weight of the combination of fingerprint informa...

Abstract

An improved encryption method and system based on comprehensive identification. S1, pre-store the decryption information of the mobile terminal, the decryption information includes the voiceprint information, fingerprint information and password information of the legal user; set the decryption authority weight of each decryption information and the combination of decryption information; S2, set the validity period of each decryption information ; S3, monitor any one or more of the voiceprint information, fingerprint information and password information on the mobile terminal in real time; S4, monitor any one of the voiceprint information, fingerprint information and password information matching the decrypted information When one or more types are used, it is judged whether the decryption information and the validity period of the combination of decryption information are within the validity period. Operation instruction, execute the decryption operation according to the decryption operation instruction, otherwise the user will be prompted that the decryption cannot be performed. The invention also provides an improved encryption system based on comprehensive identification.

Description

technical field [0001] The invention relates to the technical field of information encryption, in particular to an improved encryption method and system based on comprehensive identification. Background technique [0002] With the increasingly perfect functions of mobile terminals, the role played by mobile terminals in people's daily life is becoming more and more important. At the same time, the security of mobile terminals and privacy issues of users are getting more and more attention. At present, most mobile terminals support the encryption function, including the encryption function for the screen of the mobile terminal, such as the current password lock screen function; the encryption function for the files in the mobile terminal, such as the current album and photo album encryption function wait. [0003] However, the existing encryption passwords cannot be used universally on mobile terminals, nor can they meet the different encryption requirements of different fil...
