A novel approach for dual layer security of message using Steganography and Cryptography

It is well known that the world is becoming more interconnected with the help of World Wide Web in distributed environment. Persons and Organizations want to share their valuable information over World Wide Web through internet in reliable and secure manner. The Steganography is an elegant strategy to pass on the private data to an approved beneficiary with the most solid wellbeing measure which prompts maintaining a strategic distance from the breaks of information security. These days the meaning of taking solid assurance measures in information correspondence medium has a difficult undertaking on account of security issues created by unapproved intercession. This introduction expects to provide another methodology dependent on a combination of Cryptography and Steganography system to hide the secret information into a cover object (Image, Text, Video etc.) with an improved level of security. In proposed methodology, the Elliptic Curve Cryptography (ECC) is used to encode the secret data and LSB Inversion method for embedding the scrambled information into a cover object. Proposed methodology based on two different techniques has achieved some fundamental characteristics known as information classification, respectability check, limit and heartiness which are the proof of successful execution of this proposed methodology. This new methodology strongly tried through a few steganalysis assaults like investigation of Chi-square, Visual and Histogram. Results show that stego picture has strong resistance power against all assaults.
