Abstract: The staggering growth in communication technology and the usage of internet allows the huge transfer of data over it but because of various security threats data can be tampered by the intruders. Various cryptography techniques are developed for secure transmission over the internet, another practical approach of hiding secret information from intruders over the web is Steganography. Steganography is a technique of hiding covert data inside an image. Various techniques are discussed below for hiding data and each of them have some of their own limitations. This paper comprises of four sections. Section 1 gives a brief introduction about Steganography. Section 2 Steganograpy Techniques, Section 3 Analysis of Steganography Techniques, Section 4 Conclusion and future scope.
Keywords: Steganography, Techniques, technology usage of internet.
