摘要：

In this paper we show that a recently proposed fragile watermarking scheme by Rawat et al. does not detect and localize tampering, therefore cannot be used for authentication applications. The problem lies in that the scheme embeds an authentication code into the LSBs of pixels without taking into consideration the image content. To overcome this issue the authentication should be combined with the first seven bits of the image pixels, and in this paper a revision in this sense is proposed.
