Abstract

The invention discloses a method and system for preventing a mobile terminal from being unlocked. The method comprises the following steps: A, transmitting fingerprint data input by a user in advance to a TEE TA to encrypt the fingerprint data, and then writing the encrypted fingerprint data in a RMPB storage region; B, when needing to be unlocked, receiving the fingerprint data input by the user at present, and acquiring the fingerprint stored in the RPMB storage region, and then decrypting the fingerprint data, comparing the fingerprint data input at present with the decrypted fingerprint data, and then judging whether to unlock according to a comparison result. By use of the method disclosed by the invention, the fingerprint data of the user is encrypted in advance and then written in the RMPB storage region, even though other person picks up the user mobile phone, the user important information cannot be stolen, and the equipment security of the mobile terminal is improved.

Description

technical field [0001] The invention relates to the field of terminal security protection, in particular to a method and system for preventing mobile terminals from being unlocked. Background technique [0002] With the development of mobile terminals and the mobile Internet, the fingerprint function is gradually becoming a standard configuration item for each mobile terminal; due to the specific specificity of the fingerprint, it brings convenience and quickness in unlocking and payment, replacing the trouble and trouble of traditional digital password input. insecurity. However, the current fingerprint unlocking still has a great risk of brute force cracking, so that important data may be exposed after the user loses the mobile phone. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide a method and system for ...
