Digital Watermarking is a data hiding technique where an information or message is hidden inside a signal transparent to the user. This method is used for copyright protection of digital media. Watermarking differs from encryption in a way that in the former case a general user is allowed to access, view and interpret the signal but cannot claim the ownership of the content, whereas in case of encryption the very access to the signal itself is denied. Watermarking is thus more popular than encryption where the content generator wants the genera ....etc

ABSTRACT
Cryptography techniques aim to achieve security in communications by enciphering data. Unlike cryptography, the term Steganography refers to a set of techniques designed to provide covert communication between partners by embedding additional information into an unsuspicious communication. As a field of Steganography, the purpose of digital image watermarking (DIW) is to embed additional information into an image. This information can be later on used for copyright protection, authentication or security control purposes. In order to ....etc

DWT Based Blind Digital Video Watermarking Scheme for
Video Authentication




INTRODUCTION

Video is a three-dimensional array of color pixels. Two
dimensions serve as spatial (horizontal and vertical) directions of
the moving pictures, and one dimension represents the time
domain . Digital video offers a number of advantages over
analog video, including the ease of sharing and storage, no
degradation of data quality when replicated, easy and inexpen ....etc

Multimedia encryption Background
• Multimedia data (images, videos, audios, etc.) is being used more and more widely, in applications such as video-on demand, video conferencing, broadcasting, etc.
• In order to maintain privacy or security, sensitive data needs to be protected before transmission.
• Encryption Technique
 Transforms the data from the original form ....etc
