Embodiment approach

[0098] First enable the video recording function, and the user can choose whether to encrypt the video code stream; if not, the code stream will be directly stored in PS package form. If it is encrypted, select the face input source, which can include the local image of the encrypted device and the camera preview image. After selecting the face input source, start the face recognition algorithm, pass the face image input from the input source into the face recognition algorithm, and perform face modeling. Face modeling can support up to 256 face inputs. After the modeling is completed, the face recognition algorithm returns the modeling data, which can be stored in the form of the above structure. Then store the structure in the video code stream to obtain the encrypted code stream.

Abstract

The embodiment of the invention provides a code stream encryption and decryption method and device, and the method comprises the steps: storing face data in a code stream, i.e., carrying out the encryption of the code stream through the face data, thereby enabling a user not to need to memorize a secret key, and improving the convenience. Besides, when the code stream is decrypted, the face data to be verified is matched with the face data in the code stream, if the matching is successful, the decryption is successful, that is, the code stream is verified through the face data, and compared with a secret key, the safety of the face data is higher.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a code stream encryption and decryption method and device. Background technique [0002] In order to improve security, in some cases, the recorded code stream needs to be encrypted. In related solutions, the code stream is mostly encrypted by means of AES (Advanced Encryption Standard, Advanced Encryption Standard). This encryption method needs to provide a key for the user, and the key is usually very complicated and easily forgotten by the user, which brings great inconvenience to the user. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a code stream encryption and decryption method and device to improve convenience. [0004] In order to achieve the above purpose, the embodiment of the present application provides a code stream encryption method, including: [0005] Obtain face data and code str...
