xvii, 297 pages : illustrations ; 24 cm. "Today, more than 80% of the data transmitted over networks and archived on our computers, tablets, cell phones or clouds is multimedia data images, videos, audio, 3D data. The applications of this data range from video games to healthcare, and include computer-aided design, video surveillance and biometrics. It is becoming increasingly urgent to secure this data, not only during transmission and archiving, but also during its retrieval and use. Indeed, in today's "all-digital" world, it is becoming ever-easier to copy data, view it unrightfully, steal it or falsify it. Multimedia Security 2 analyzes issues relating to biometrics, protection, integrity and encryption of multimedia data. It also covers aspects such as crypto-compression of images and videos, homomorphic encryption, data hiding in the encrypted domain and secret sharing." Biometrics and applications -- Protecting documents using printed Anticopy elements -- Verifying document integrity -- Image crypto-compression -- Crypto-compression of videos -- Processing encrypted multimedia data using homomorphic encryption -- Data hiding in the encrypted domain -- Sharing secret images and 3D objects. coordinated by William Puech.
