Devanagari text embedding in a gray image: An offbeat approach

Abstract

Steganography is a tool which helps in hiding information that plays a crucial role in many ways and in many lives. With the advent of the Internet, information exchange is possible in many languages other than English. This technology eventually carries with it a disadvantage which is the loss of security and privacy of information. Steganography an insipid medium, is one such way to ensure privacy. Steganography plays a vital role in securing the secret data. In this paper, a different approach is chosen for encoding Devanagari (Hindi) Text in the cover image. This approach of hiding Devanagari (Hindi) and English Text in an alternate manner is very efficient and simple to use. This paper describes a duplet algorithm, one for encoding and another for decoding. The image parameters are calculated by this proposed methodology, which proves that this process is more efficient and innovative.
