Image watermarking via wavelet approach and face biometrics

In this paper, we consider a new highly-performing system to establish the intellectual property of a file by using advanced Information Fusion (IF) techniques based on Face Biometrics (FB) and Wavelet Multiresolution Analysis (WMA). IF is used in different depending on the fact that it can be a textual file, an image or multimedial; indeed, the further step consists in creating blue biometric codes with different watermarking mechanisms based on: i) face features, ii) wavelets and wavelet packets respectively. It seems clear that such a system can be useful for all that concerns files/contents distributed online for what regards both the intellectual property and the access/modification/use of information. At the end we also show a new method, based on information entropy, to track the access and use of a specific file by different users. Indeed, thanks to our approach we can also know the sequence of the users.
