Abstract

The present invention provides a data processing method and apparatus. The method includes the following steps that: an ROI region in a monitoring image is determined; concealment processing is performing the ROI region in the monitoring image, so that a first image and a second image can be obtained; JPEG encoding is performed on the first image, and the first encoded image is made to be carried in the frame field of a JPEG code stream; JPEG enhancement encoding is performed on the second image, the second encoded second image is made to be carried in the APP field of the JPEG code stream, and the APP field is encrypted; and the JPEG code stream is sent to a decoding side device. With the data processing method and apparatus of the invention adopted, it can be ensured that authorized users and unauthorized users can view different monitoring images.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a data processing method and device. Background technique [0002] In video surveillance systems, security issues are becoming increasingly important. The security of the video surveillance system includes device access security, user access security, code stream transmission security, storage security, and so on. From this point of view, the picture transmission and storage in the video surveillance system must also be safe. The so-called picture security means that even if the pictures transmitted and stored in the video surveillance system are obtained by criminals, the important information in the pictures cannot be seen, but the unimportant information in the pictures can be seen. [0003] At present, the more common way to ensure the security of pictures is to mosaic the main identity part (such as face) of a specific object in the picture, so that the viewer c...
