Title: STEGANOGRAPHY AND VISUAL CRYPTOGRAPHY IN COMPUTER FORENSICS Page Link: STEGANOGRAPHY AND VISUAL CRYPTOGRAPHY IN COMPUTER FORENSICS - Posted By: smart paper boy Created at: Monday 29th of August 2011 12:30:28 PM	steganography cryptography er diagram combine, steganography forensics, latest cse ppts on computer forensics, data flow diagram online payment system using steganography and visual cryptography, powerpoint presentation on visual cryptography, seminar report of computer forensics topic, documentation visual cryptography,
Presented By: MELVIN PAUL ABSTRACT Recently, numerous novel algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency. This paper discusses and compares the two methodologies. Some similarities and differences are presented, in addition to discussing some of the best known algorithms for each. Lastly, an idea for a possible algorithm which combines the use of both steganography and visual cryptography is suggest ....etc [:=Read Full Message Here=:]

Cheating Prevention in Visual Cryptography (Java) IEEE Transactions on Image Processing, Vol. 16, No. 1 Abstract: Visual cryptography (VC) is a method of encrypting a secret image into shares such that stacking a sufficient number of shares reveals the secret image. Shares are usually presented in transparencies. Each participant holds a transparency. Most of the previous research work on VC focuses on improving two parameters: pixel expansion and contrast. In this paper, we studied the cheating problem in VC and extended VC. We co ....etc [:=Read Full Message Here=:]

Abstract Visual cryptography is a popular solution for image encryption. Using secret sharing concepts, the encryption procedure encrypts a secret image into the so-called shares which are noise-like secure images which can be transmitted or distributed over an untrusted communication channel. Using the properties of the human visual system to force the recognition of a secret message from overlapping shares, the secret image is decrypted without additional computations and any knowledge of cryptography. Visual cryptographic solutions ope ....etc [:=Read Full Message Here=:]
