Diptee D. Lad, Prof. Sindhu M. We are the use of cryptographic and spreading sensitive information with outsiders. The method for steganographic techniques for hiding the data. Cryptography is data encryption and decryption are achieved in two parts the information hiding skill; there is more than one algorithm Symmetric encryption and Asymmetric encryption [4].

Part of the Lecture Notes in Computer Science book series LNCS, volume Abstract The abstract should summarize the contents of the paper and should Steganography is a technique to hide secret information in some other data we call it a vessel without leaving any apparent evidence of data alteration. All of the traditional steganographic techniques have limited information-hiding capacity. This is because the principle of those techniques was either to replace a special part of the frequency components of the vessel image, or to replace all the least significant bits of a multi-valued image with the secret information.

Our new steganography uses an image as the vessel data, and we embed secret information in the bit-planes of the vessel. This technique makes use of the characteristics of the human vision system whereby a human cannot perceive any shape information in a very complicated binary pattern. This process is experimental and the keywords may be updated as the learning algorithm improves. This is a preview of subscription content, log in to check access. Preview Unable to display preview.

Published26 Mar Abstract Bit-plane complexity segmentation BPCS steganography is advantageous in its capacity and imperceptibility. The important step of BPCS steganography is how to locate noisy regions in a cover image exactly. The regular method, black-and-white border complexity, is a simple and easy way, but it is not always useful, especially for periodical patterns. Run-length irregularity and border noisiness are introduced in this paper to work out this problem. Conjugation operation is applied to convert simple blocks into complex ones. The higher the bit-plane is, the smaller the complexity is.

Steganography

A typical vessel is a color image having Red, Green, and Blue color components in a multi-bit data structure. The general scheme of steganography is shown in the other page where we will also refer to a file camouflage technique in brief. Eason in It can embed confidential information in vessel data which is typically a true color image bit BMP format and sometimes in an 8-bit indexed color image. Embedding actually, replacing is made on the bit-planes of the image.
