Content Srambling System
Abstract
Content Scramble System (CSS) is an encryption system used on some DVDs. It uses a weak, proprietary 40-bit encryption stream cipher algorithm. The system was introduced circa 1996.. The CSS key sets are licensed to manufacturers who incorporate them into products such as DVD drives, DVD players and DVD movie releases. Most DVD players are equipped with a CSS Decryption module. CSS key is a collective term for authentication key, disc key, player key, title key, second disk key set, and/or encrypted key ....etc

ABSTRACT

Chaos maps and chaotic systems have been proved to be useful and effective for cryptography. In our study, the two-dimensional logistic map with complicated basin structures and attractors are first used for image encryption. The proposed method adopts the classic framework of the permutation-substitution network in cryptography and thus ensures both confusion and diffusion properties for a secure cipher. The proposed method is able to encrypt an intelligible image into a random-like one from the statistical point of view and the hum ....etc

Efficient Frequency Domain Selective Scrambling of Digital Video at java

Abstract:
Multimedia data security is very important for multimedia commerce on the Internet such as video-on-demand and real-time video multicast. Traditional cryptographic algorithms/systems for data security are often not fast enough to process the vast amount of data generated by the multimedia applications to meet the real-time constraints. This paper presents a joint encryption and compression framework in which video data are scrambled efficiently in the ....etc

Project type: System project, tools
Project title: Data Scrambling tool
Abstract
Banks need to protect the identity of its customers. Therefore there is a need to mask all the confidential data, such as, customer name and address, required for its testing. Further masking has to be done in a way such that the integrity of the data in terms of check digits, range checks based on branch code / product types etc. is not lost.
The Data scrambling tool will mask the Production Data. The masked data will reside in a normalize ....etc

In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this communication, we propose a new approach for image encryption based on chaotic logistic maps in order to meet the requirements of the secure image transfer. In the proposed image encryption scheme, an external secret key of 80-bit and two chaotic logistic maps are employed. The initial conditions for the both logistic maps are derived using the external secret key by providing different weig ....etc
