New Rapid And Secure Steganography Algorithm Using Chaotic Sequence And Based-On Steerable Pyramid

Steganography is tremendous field of research in the area of information hiding. The aim of steganography is concealing a message within ordinary message in order that the ordinary message remains seemingly changeless. Major challenge in steganography is achieving to a method with high security, high capacity, and high imperceptibility. Also, speed of embedding process of the steganography algorithms is another challenge that has been neglected in most of previous works. In this paper we propose a novel secure and rapid steganography algorithm that covers a collection of advantages of former methods. The most important features of our algorithm are: increasable capacity, reliable security, quickness and proper imperceptibility. For obtaining to these features we exploited steerable pyramid and chaotic sequence for embedding secret message bits.
