Comparision of cipher.

Thus, our system proves to be very useful for the overall development of our technologies. Steganography has its place in security. Hiding a message with steganography methods reduces the chance of a message being detected.

There are an infinite number of steganography applications. This paper explores the art of steganography. Steganography does not only include the digital images but also the other media (files such as video, binaries; other media such as communication channels via audio, the list can go on and on).

Thus, we have designed a software which really has a very good application in real world. It will be notable feature as this system is very easy and customizable makes it useful to wide variety of the users for Security purposes.

Conclusion:

Thank you!!!
