Wong and Memon =-=[20]-=- use the security of a proven cryptographic hash function for a block-wise independent digital watermarking scheme to work against the counterfeiting attack.

Kim, Real-Time Blind Watermarking Algorithm and its Hardware Implementation for Motion JPEG2000 Image Codec, in: Proceedings of the 1stWorkshop on Embedded Systems for Real-Time Multimedia, 2003, pp.

On the contrary, security received little attention in the watermarking community.

the security of the watermarking ..

We list the typical applications which requires a secure watermarking technique.

Second, Strict Authentication Watermarking with JPEG Compression (SAW-JPEG) uses the same principal as SAW, but is able to survive some degree of JPEG compression.

Watermarking schemes for authentication purposes are characterized by three factors namely security, resolution of tamper localization, and embedding distortion.

The iterative approach of IWE can prevent the potential removal of a watermark in the JPEG recompression process.

In this paper we examine the security of the Yeung-Mintzer authentication watermarking technique and show that it is vulnerable to different types of impersonation and substitution attacks whereby an attacker is able to either create or modify images that would be considered as authentic.

efg's Image Processing: Algorithms

Experimental results show that embedded watermarks using the proposed techniques can give good image quality and are robust in varying degree to JPEG compression, low-pass filtering, noise contamination, and print-and-scan.

This system is capable of enhancing the security during the transmission of medical images through a wireless channel, in two ways: initially by using the default IEEE 802.11 security, WEP and additionally by applying DFRFT domain digital watermarking to the medical images before transmitting them through the wireless channel.
