Scalable fragile watermarking for image authentication
IET Information Security, 2013 Semi‐fragile watermarks are used to detect unauthorised changes to an image, whereas tolerating allowed changes such as compression. Most semi‐fragile algorithms that tolerate compression assume that because compression only removes the less visually significant data from an image, tampering with any data that would normally be removed by compression ...
