Abstract
Many image watermarks have been proposed to protect intellectual property in an age there digital images may be easily modified
and perfectly reproduced. In a fragile marking system, a signal (watermark) is embedded within an image such that subsequent alterations to the watermarked image can be detected
with high probability. The insertion of the watermark is perceptually invisible under normal human observation. These types of
marks have found applicability in image authentication systems.
In this paper we discuss fragile marking systems and their desirable features, common methods of attack, and survey some recent marking systems.
