Secure Data using 2-steps Encryption and Steganography to avoid Data theft.

Data Security is the most important concern in the terms of modern communicating era. Encryption is the best and the effective way to provide data security and privacy. Most of the modern encryption systems are based on only one step of encryption and decryption which have some drawbacks of data theft but in this application, we have used two step encryption and decryption for better security. In this application, we have used one custom encryption and decryption method and also Advance Encryption Standard. Advance Encryption Standard is based on a principle known as a substitution–permutation network, and is very use full in hardware and software. We have also used Steganography it is the technique which is used to hide the secret data into an ordinary or non-secret file to avoid detection. Steganography can be combined with encryption technique to provide an extra step for protection. In this application we can hide a secret message into an ordinary image and also do text encryption and decryption.
