A novel Android based Mobile application as a virtue of covert communication for concealing information in the Speech signal

The era of Multimedia communication and its application on Mobile devices have gained momentum with the onset of Android platform. Here we have considered Speech signal as the cover signal to hide the sensitive data in it. We can develop the same application on the Android platform using its IDE (Integrated Development Environment); one such is provided by Eclipse. The proposed approach is quite crucial in military-warfare conditions, as well in the defense related Information Communication. The covert nature is the desirable feature which denies an unauthorized user from mining sensitive information or claiming the ownership of music in case of water-mark embedding.
