Decryption method and device

Abstract

The embodiment of the invention provides a decryption method and device. The method is applied to a first terminal, the first terminal performs data interaction with a second terminal, the first terminal is provided with a key database, the second terminal is provided with a face recognition data database, the face recognition data database includes one or more sets of face recognition data, and each set of face recognition data respectively has keys with an association relationship. The decryption method includes the following steps: when the first terminal enters a decryption mode, sending akey acquisition request to the second terminal; receiving a key sent by the second terminal, wherein the key is matched by the second terminal from the face recognition data database; matching the key with the key database; and if a match item exists, decrypting the first terminal by using the key. According to the embodiment of the invention, the decryption of the first terminal can be implemented in the case that a user does not input a password, the cumbersome operation that the user inputs the password can be eliminated, and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a decryption method and a decryption device. Background technique [0002] With the development of science and technology, the storage capacity of computing devices, such as computers and smart phones, is increasing, and users can store more and more data, but correspondingly, user privacy is becoming more and more important. [0003] In practical applications, in order to protect their privacy, users usually encrypt their devices by setting a password to prevent others from using their devices. However, this method has two disadvantages: [0004] 1. The user needs to enter the password every time, and the operation is cumbersome; moreover, if the user forgets the password, the device cannot be decrypted; [0005] 2. If others know the password, they can also decrypt the device without the user's knowledge, which is less secure. Contents of the invention...
