A simple yet efficient solution for secured data exchange - Hiding encrypted text in an image file
Lawrence Wu, Penn P. Wu · Advances in intelligent systems research/Advances in Intelligent Systems Research · 2013
Hiding encrypted text in an image file can possibly be a feasible solution to small-office-home-office (SOHO) and personal use for data and file transmission across digital networks. In this paper, the au-thors propose a simple, low-cost, but effi-cient algorithm to (a) convert a text (short or lengthy) to a byte array with a simple encryption mechanism, (b) append the byte array to an existing image file as hidden content without changing the orig-inal viewable image, and (c) retrieve and decode the encrypted text with a reverse algorithm and required keys. The authors also discuss the algorithm with Windows application created based on the proposed algorithm.
