Cryptanalysis aspects in 3-D watermarking
Résumé
3-D object security is increasingly brought to the attention of the public by the expansion of new multimedia technologies such as the 3-D printing. In the development of crypto-security systems of 3-D objects, we can identify two major directions represented by the cryptography and digital watermarking. A good security system has to be format compliant, has to preserve the original bit rate and, whenever possible, it should be reversible. Watermarking methodology has the advantage of ensuring that the embedded hidden message can be verified at any processing stage such as the transmission, storage and when visualizing the embedding media. In this paper, we review the previous work in 3-D security and analyze the crypto-security of a 3-D watermarking method which embeds information by mesh surface distortion minimization. Then, we discuss future avenues of research by presenting emerging applications.
