Testing methods for the efficiency of modern steganography solutions for mobile platforms

Cryptography and Steganography are two commonly used techniques in modern era for ensuring confidential and private communication. These techniques complete each other offering multiple layers of safety, enhancing digital information security. In this paper we analyze Smartsteg, which is a project that implements cryptography combined with steganography on mobile devices that run Android and Windows. We evaluate the performance of this project in terms of: interoperability, security, payload capacity, speed and robustness against steganalysis.
