摘要：

Image authentication is one of the security checks to detect any forgery or malicious manipulations, which may have occurred due to insecure transmission. An effective scheme is proposed in this paper which can detect the tampering and also it supports the image compression. A digital signature corresponding to the image will be transmitted along with the image itself. Receiver will regenerate the signature corresponding to the received image and if both the signatures match, it means there is no tampering of data and the received image is authentic (or original). As it allows lossy compression techniques therefore matching is done by setting some threshold value. For example with 10% tolerance if both hash files match up to 90% the image will be considered as authentic.
