Weaknesses of copyright marking systems

چکیده
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 possible benchmark to compare these systems on a fair basis. 1.1

One of the main problems of the creators of literary, scientific, artistic and cultural works in the country is the lack of observance of the related ethical rules and laws to the protection of copyright in connection with the public rights. Regarding to recent advances and developments, meanwhile explanation of the global sphere of the copyright, present study explores the current situation of...
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 کاملMarking Estimation of Petri Nets with Arbitrary Transition Labeling
In this paper we deal with the problem of estimating the marking of an arbitrary labeled Petri net system where two forms of nondeterminism may occur. Firstly, there may exist unobservable transitions, i.e., transitions labeled with the empty string. Secondly, there may exist undistinguishable transitions, i.e., two or more transitions sharing the same symbol taken from a given alphabet E may s...
متن کاملStudy on Copyright Authentication of Gis Vector Data Based on Zero-watermarking
GIS vector data is closely linked with the development of social economy and national defense, which is of high production cost and high precision, so the copyright protection of GIS vector data means a great deal and the copyright authentication of GIS vector data has become an increasingly complex topic. In recent years, researches about copyright protection of GIS vector data mainly focuses ...
متن کاملFlow Control for Continuous Petri Net Models of Hds : Stability Issues
This paper is about the flow control design of hybrid dynamical systems modelled with continuous Petri nets and described as a set of bilinear state space representations. The marking vector stands for the state space vector, where some places are observable and other are not. The transitions are divided into controllable ones and uncontrollable ones. Gradient-based controllers are investigated...
