A Novel Information Security Scheme by Creptic Video Stegnography

With a successive development of multimedia technology more and more data not only generated but also transmitted too, in several fields some of them are military fields, medical fields etc which should secure their information therefore security and privacy both are important. In this paper a description of a system where video and document files both are important and should be secure. This system give an idea for successfully achieve secure information and efficient communication. We make a combination Stegnography and Cryptography for achieving efficiency (in terms of encryption speed, security and stream size) and flexibility (Platform), It is a challenge or future scope for researches. stenograph video with text(Using Least significant bit algorithm) then applying any multimedia encryption algorithm over stegno-data, so receiving end perfrom reverse operation to decrypt the information.
