J. Luo, Student Member, IEE, K. R. Pattipati, Fellow, IEE, P. K. Willett, Senior Member, IEE, and F. Hasegawa, Member, IEE
Abstract
A Probabilistic Data Association (PDA) method is proposed in this letter for multiuser detection over synchronous code-division multiple-access (CDMA) communication channels. PDA models the undecided user signals as binary random variables. By approximating the inter-user interference (IU ....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

Hi,

I need some details regarding 'Wireless CDMA/GMS based Data Transmission'.
Basically a document/article explaining how it works practically and which are the products already available in the market.
What kind of data can be transmitted through this technology.?
Any technical limitations i may face later while using this in my project?

This is regarding a project which i want to work for my final year which is in the initial state.

Thanks in advance,
ZBasheera ....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

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
