Contents based Still-Image Protection Method using Seam Carving Algorithm

This paper proposes a new contents-based still image protection method which includes a copyright message. The existing method uses random number generator for contents vector generation. Since the existing method is able to select less important pixel, Authentication failure error rate increases in case of authenticating attacked image. In this paper, contents vector consisting of important pixels using energy value by Seam Carving algorithm is used instead of random pixel selection method when creating contents vector from original image. The experimental results show over 90% great performance from cropping attack while show performance from most attacks similar to existing algorithm.
