With the ever increasing amount and variety ofdata to be stored and transmitted in various mediums,the specification of security which has to beestablished at various levels of medium access and theaccompanying issues of authentication andauthorization has become a critical factor. Varioussteganographic, watermarking and data-embeddingalgorithms have usually manipulated the actual data inorder to either hide any coveted information or toprovide some level of access control over the medium.The mediums are usually images, video, audio etc.,wherein specific portions or the overall space isusually 'corrupted' with 'significant' data. This paperis an attempt to bring out the significance of thesteganographic techniques that are employed ininformation processing algorithms for data security. Itdeals with the problem of data security, focusingmainly on images, and tries to state the variousproperties and characteristics that the steganographicalgorithms should possess. The paper also highlightsthe technique of masking used in the conventionalsteganographic LSB algorithms and in its variants.
