Abstract

The invention discloses an image data transmission method and device and an image data receiving method and device. The method comprises the following steps: encoding target frame image data to obtainan initial code stream corresponding to the target frame image data, the target frame image data being image data to be transmitted; encrypting the header information of the initial code stream to obtain encrypted header information; obtaining a digital signature of the initial code stream through the encrypted header information; and adding the digital signature to the initial code stream to obtain a target code stream, and sending the target code stream to a data receiving end. According to the invention, the technical problem of low reliability of an image data transmission mode in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of image data processing, in particular to an image data transmission method and device, and an image data receiving method and device. Background technique [0002] At present, wireless image transmission products mainly encode the image data collected by the S terminal (data collection terminal) through WIFI, and then transmit it to the R terminal (data receiving terminal) for decoding and display. During the encoding and decoding process, the captured images are usually encoded using a preset encoding protocol, such as H264 encoding protocol, progressive encoding, and so on. The encoding process is: in the process of data transmission, a frame of data is collected at the S terminal for encoding, and then the encoded data is sent to the R terminal for decoding and display. In this process, if the data transmission channel is hijacked by others, and then the encoded code stream of other image data ...
