Evaluation of Watermarking Techniques
Journal Title: INTERNATIONAL JOURNAL OF MATHEMATICS TRENDS AND TECHNOLOGY - Year 2012, Vol 3, Issue 2
Abstract
Now a days the copyright of multimedia and secrete information is very difficult to transfer across the internet multimedia objects must be compressed before transmitting the data. The JPEG compression is one of the most important criteria in watermarking issue. Watermarking, which belong to the information hiding technique? There is a lot of work begin conducted in different branches in this field,Stegnography is used for secret communication, whereas watermarking is used for content protection, copyright management, content authentication and tamper detection. We classify the techniques based on different domains in which data is embedded. Here we limit the survey to images only. However, making digital data accessible to others through networks also creates opportunities for malicious parties to make sailable copies of copyrighted content without permission of the content owner. Digital watermarking techniques have been proposed as a solution to the problem of copyright protection of multimedia data in network environments.

Existence of Solutions to Quasilinear Delay Differential Equations with Nonlocal Conditions
We prove the existence and uniqueness of mild and classical solution to a quasilinear delay differential equation with nonlocal condition. The results are obtained by using C0-semigroup and the Banach fixed point theorem...
Analysis of Queuing Model for Machine Repairing System with Bernoulli Vacation Schedule
In this paper, we consider a queueing model for machine repairing system with Bernoulli vacation schedule. The failure times, repair times and vacation times are all assumed to be exponentially distributed. In congestion...
