Glossary

Key: A key is a secrecy necessary to identify a mark. In the principal models of watermarking, it as well makes it possible to register the mark as lira or to remove it. This is why it must remain secret. The protocols setting up this type of marking at symmetrical key utilize the use of third of confidence, guards of the key.

Cryptology : to transform data, which it acts of information or signals, using secret conventions or to carry out the opposite operation of this transformation with or without secret convention

Fingerprinting: The fingerprinting is an application of the watermarking in which the mark (the print then is said) varies from one person to another. In the case of a diffusion of illegal copies, one can thus find the people whose specimen of the medium is at the origin of the fraud.

Rights Went back Dictionary - Dictionary to rights : aim at defining an organized list of terms corresponding to granted rights, while envisaging the possibility of managing different significances according to the legislation.

Rights Expression Language-- Language expressing the rights : aim at defining the granted rights, the recipient, the resource concerned and the conditions for application.

Steganography: The steganography is the science which consists in hiding information in any medium so that only a user provided with the adequate secrecy can find this information.

Tattooing: A process of marking utilizes two concepts: tattooing and the extraction. Tattooing is the stage where the mark is encrusted on the medium.

Traceability: This Anglicism indicates the possibility «of tracing» a culprit : when a reasonable coalition of size people agree to break a safety (cryptographic or of marking), one wants to identify at least one of the members of this coalition.

Watermarking : Process which consists in hiding in a file a code of property quantified to guarantee the royalties in particular and/or to limit his use. It supplements or replaces the encoding of the type DRM.
