Image data transmitting and receiving method and camara terminal and server for image forgery detection in security camera system

摘要

In the present invention, instead of inserting a watermark into image data to be transmitted from a camera terminal of a security camera system, a hash code corresponding to the image data is generated based on data of a partial area of the image data, Channel to transmit the image data to the server, and to easily confirm whether or not the image data is forged or falsified by the server, and to a camera terminal and a server for transmitting and receiving image data through the image transmitting and receiving method, , It is possible to easily perceive the forgery and falsification of the image data without distorting the image data itself. Accordingly, it is possible to prevent an intentional attack by an unauthorized third party from damaging the contents of the image data, and it is possible to ensure that the image data received at the server is an original image without forgery.
