Abstract

One of the extensively applied methods for well-secured communication is steganography, which is also referred to as secret writing. A variety of techniques such as the application of invisible ink and masking the secret text inside an inconspicuous text existed during the early days. Steganography helps to conceal information between the sender and intended recipient so that others are not aware of the message's presence in the information. Digital steganography applies to different media like executable files, images, audio and videos, text and games. This paper conducted a literature review on different algorithms for image steganography using LSB techniques. A suggestion was made to show how the LSB technique can be further enhanced.
