For example, the cryptography can be used to prove the presence of a specific watermark in a digital object without compromising the watermark security.

Based on the above two types of watermarking schemes, current researches on watermark extraction can be categorized into two broad topics: watermark decoding [12, 13, 19] for the case of decoding the hidden message and watermark detection [16 18, 20 22] for the case of detecting the presence of a specific watermark.

For the latter case, the detection of the presence of a potential watermark in a specific feature space can lead to new attacks or to a better design of the watermarking pattern.

Passive attacks can have different objectives such as detecting the presence of a valid watermark or knowing the associated information being carried by it.
