Abstract

The embodiment of the invention provides a file encryption and decryption method, device and equipment. The method comprises: acquiring image data; determining face image features according to the image data; determining at least one of a facial action, a facial action sequence, expression information and gesture information according to the image data; and encrypting the to-be-encrypted file according to the determined face image features and the determined at least one of the face action, the face action sequence, the expression information and the gesture information. The method provided bythe embodiment of the invention is simple and convenient to operate and high in safety.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a file encryption and decryption method, device and equipment. Background technique [0002] Encrypting files can effectively protect user data security and personal privacy. With the continuous improvement of user security awareness, the demand for file encryption and decryption is also increasing. [0003] Existing file encryption is generally performed by character strings, and users need to input character strings in the process of encryption and decryption, which is cumbersome to operate, and the user experience is not good, and encryption by character strings is easy to crack and has low security. Contents of the invention [0004] Embodiments of the present invention provide a file encryption and decryption method, device, and equipment to solve the problems of low efficiency and low security of existing file encryption and decryption meth...
