Secure Image Hiding Algorithm using Cryptography and Steganography
Hemlata Sharma · IOSR Journal of Computer Engineering · 2013
In the present scenario, any communication of internet and networks application requires security.Lots of data security and data hiding algorithms have been developed in the last decade.Cryptography and steganography are the two major techniques for secret communication.In this paper,the secret image is first encrypted by using BLOWFISH algorithm which has very good performance and is a most powerful technique compared to other Algorithms. Now this encrypted imageis embedded with videoby using LSB Approach of steganography. Our proposed model gives two layers of security for secret data, which fully satisfy the basic key factors of information security system that includes: Confidentiality, Authenticity, Integrity and Non - Repudiation.
