Selective image authentication tolerant to JPEG compression

A watermark application in the integrity maintenance and verification of associated images is considered. There is a great advantage of watermark use in the context of conventional authentication since it does not require additional storage space for supplementary metadata. However JPEG compression, being a conventional method to compress images, leads to breaking of exact authentication. The usage of occuring selective authentication, tolerant to JPEG compression, is proposed. This technique is based on execution of Zernike moments. The performance evaluation of the proposed method depending on a compression factor is estimated. Simulation results show a good efficiency of this approach, including resistance to malicious attacks rather important within the frame of Security and Privacy in Future Generation Services topics.
