A Comparative Analysis for Video Watermarking Techniques

Video Watermarking Techniques: A Review

Present era shows a rapid growth in the progress of digitization and creation of digital multimedia content. Image and Video makes up the majority component in digital multimedia content. The potential solution for protection and prohibiting copyright infringement of multimedia is only using digital watermarks. The characteristic of robustness, i. e. , sustainable capability to withstand agains...

A chaos-based video watermarking algorithm

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental ...

Two Novel Chaos-Based Algorithms for Image and Video Watermarking

In this paper we introduce two innovative image and video watermarking algorithms. The paper’s main emphasis is on the use of chaotic maps to boost the algorithms’ security and resistance against attacks. By encrypting the watermark information in a one dimensional chaotic map, we make the extraction of watermark for potential attackers very hard. In another approach, we select embedding po...

Digital Image Watermarking Techniques: A Comparative Study

Digital watermarking plays an increasingly important role for proving authenticity and copyright protection. The Internet is an ideal medium for selling digital goods it also makes redistribution of pirated files very easy. Digital watermarking can be used to insert invisible data into an object helping to track down pirate copies and to prove rightful ownership in a dispute. In this paper we p...
