Steganography is the art and science of hiding information by embedding data into cover media. In this paper we propose a new method of information hiding in digital image in spatial domain. In this method we use Plane Bit Substitution Method (PBSM) technique in which message bits are embedded into the pixel value(s) of an image. We first, proposed a(More)
In this paper, two new Manchester encoders based on transmission logic gates (TLG's), current sink inverter multiplexer (CSIM) and active N-MOS load inverter multiplexer were presented. Manchester encoding is a special case of binary phase-shift keying (BPSK), where the data controls the phase of a carrier (square wave) whose frequency is the data rate. The(More)
Security has become an important issue with the proliferation of digital communication. Multimedia sources such as images plays an important role in security of data communication. Data hiding technique can be used to implant secret data in host images where existence of data is undisclosed which reduces chances of unauthorized access. Some applications(More)
