Weaknesses of copyright marking systems
1. ABSTRACT Hidden copyright marks have been proposed as a solution for solving the illegal copying and proof of ownership problems in the context of multimedia objects. We show that the first generation of systems does not fulfil the expectation of users through a number of attacks that enable the information hidden by them to be removed or otherwise rendered unusable. We also propose a possib...
متن کاملEvaluation of Copyright Marking Systems
Hidden copyright marks have been proposed as a solution for solving the illegal copying and proof of ownership problems in the context of multimedia objects. Many systems have been proposed, but it is still difficult to have even a rough idea of their performances and hence to compare them. So we first describe some general attacks on audio and image marking systems. Then we propose a benchmark...
متن کاملAttacks on Copyright Marking Systems
In the last few years, a large number of schemes have been proposed for hiding copyright marks and other information in digital pictures, video, audio and other multimedia objects. We describe some contenders that have appeared in the research literature and in the field; we then present a number of attacks that enable the information hidden by them to be removed or otherwise rendered unusable....
متن کاملELEMENTAL MARKING OF ARlHROPOD PESTS IN AGRICULroRAL SYSTEMS: SINGLE AND MULnGENERAnONAL MARKING
Use of elemental markers to study movement of arthropod pests of field crops is reviewed. Trace elements, rubidium (Rb) and cesium (Cs), have provided a nondisruptive method of marking natural adult populations via developmental stage consumption of treated host plants. Multigenerational marking occurs with the transfer of elemental markers from marked adults to reproductive products, including...
متن کاملThe Evolution of Case Systems for Marking Event Structure
Case has fascinated linguists for centuries without however revealing its most important secrets. This paper offers operational explanations for case through language game experiments in which autonomous agents describe real-world events to each other. The experiments demonstrate (a) why a language may develop a case system, (b) how a population can self-organize a case system, and (c) why and ...
