Auditory Cryptography Security Algorithm With Audio Shelters

Audio Steganography and Security Using Cryptography

Security is as strong as the weakest link. Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper. This paper presents the technique for the above requirement. In the proposed method, we use Steganography technique where secret message is embedded within a carrier audio file and the existence of message is hidden from the...

Advance cryptography algorithm for improving data security

Information security is the process of protecting information. It protects its availability, privacy and integrity. Access to stored information on computer databases has increased greatly. More companies store business and individual information on computer than ever before. Much of the information stored is highly confidential and not for public viewing. In this paper I have developed a new c...

An Enhanced Symmetric Key Cryptography Algorithm to Improve Data Security

This work uses enhanced symmetric key encryption algorithm, in which same structure of encryption and decryption procedure algorithm is used. In conventional encryption methods the key for encryption and decryption is same and remain secret. The algorithm uses key generation method by random number in algorithm for increasing efficiency of algorithm. The algorithm use key size of 512 bits for p...

Enhancement of Security in Visual Cryptography System using Genetic Algorithm

Visual Cryptography (VC) is a special type of encryption technique where an image or document is encrypted by breaking it down into shares. These shares are then printed on transparencies. Decryption is done by superimposing the shares. Thus one can visually decode the secret image without computation. However, this property makes VC insecure as a third party can easily retrieve the secret info...
