Data security plays an important and integral part in communication technology. The demand for data security remains as high as ever as technologies evolve, especially in this era of rapid changing technology. A method of securing data can be seen steganography, which is the art of hiding data. This paper proposes for two algorithms, which are Least Significant Bit (LSB) and Peak Signal to Noise Ratio (PSNR), to be combined and utilized together to create an Android based Digital Steganography Application. As such, the contributions in this paper will benefit the field of data security particularly in the mobile environment as to the implementation of the two algorithms.
