A Simple Approach on Image Authentication Watermarking

An ideal watermarking scheme is a technique of embedding secret information into the image in order toauthenticate the image. This helps in detecting The integrity of the image. Here a block based Watermarking technique has been sed. A Fuzzy C means based algorithm is used here to Watermark and authenticate the image Experimental result here show that it can detect maximum modification and it c...

Watermarking for Image Authentication

A data embedding method is proposed for image authentication based on table look-up in frequency domain. A visually meaningful watermark and a set of simple features are embedded invisibly in the marked image, which can be stored in the compressed form. The scheme can detect and localize alterations of the original image, such as the tempering of images exported from a digital camera.

Multi-resolution Image Authentication Watermarking Based on Progressive Image Transmission

In this paper, a watermarking for multi-resolution image authentication is proposed. The most important image content with progressive characteristic is taken as the authentication code. The authentication code is then embedded/extracted according to multi-resolution image coding. The experimental results show the validity of the proposed scheme. The significant tampering can be detected firstl...
