Encoding and Decoding of File to Image

Abstract

The past decade has seen a rise in the field of image file processing techniques. By techniques, we mean image file transfer, compression etc. The techniques pertaining to an image file are more versatile than those to normal computer files. For example, many messaging mediums allow transfer of image files but have limited support for transfer of ordinary files. Therefore, the representation of a given file as an image will allow all the technologies specialized to image files to be applied to ordinary files. Presented in this paper are methodologies to encode any file as a bitmapped image and to recover the file from a given image. This methodology has promising applications in a wide variety of fields like cryptography, file compression etc.
