Abstract : This paper presents yet another attempt towards robust and secure watermarking. Some recent works have looked at this issue first designing new watermarking schemes with a security oriented point of view, and then evaluating their robustness compared to state-of-the-art but unsecure tech- niques. Our approach is, on contrary, to start from a very robust watermarking technique and to propose changes in order to strengthen its security levels. These changes in- clude the introduction of a security criterion, an embedding process implemented as a maximization of a robustness met- ric under the perceptual and the security constraints, and a watermarking detection seen as a contrario decision test. Our experimentations lead to, once again, a trade-off be- tween security and robustness. The technique is now per- fectly secure against attacks mounted during the second edi- tion of the BOWS challenge, but the price to pay is either a lower robustness against common image processing, either a bigger probability of false alarm.
