What is Stego Image

In this smart age, smart gadgets with internet connectivity have become necessity of modern life. While enjoying these facilities one must count the security of their private or confidential information. With due time, a lot of cryptographic methods have been developed for enforcing security. On the other hand, with the advancement of technologies the intruders and hackers have also developed their skills and tools. Therefore, many times we fail to protect our information. To get rid of this situation, the developers have to focus on some other method besides cryptography. Steganography can be considered as the solution to overcome this problem, as it is the technique which conceal the existence of any secret information in a usual media file. Moreover, inclusion of biometric with steganography enhances the security level, as biometric systems are dominating the field of authentication nowadays. Here, various techniques of steganography, biometric and steganography using biometrics will be discussed. Finally present scenario of steganography using Biometrics will be demonstrated.
