Steganographic Data Hiding using Modified APSO

Abstract

In this paper we are analy zing the steganographic data hiding using the least significant bit technique. This paper describes the particle swarm optimisation. The particle swarm optimisation algorith m is applied to the spatial domain technique. The improved algorith m called the accelerated particle swarm optimisation converges faster than the usual particle swarm optimisation and imp roves the performance. This paper also analyses the modified part icle swarm optimisation on the spatial domain technique which improved the PSNR and also reduced the computation time.
