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 image is embedded with video by using LSB approach of steganography.
