BPCS Steganography. The goal of steganography is to hide a message in plain sight. BPCS is a method to embed a message in an image by replacing all. Principle of BPCS-Steganography. (Bit-Plane Complexity Segmentation Based Embedding). (KIT-STEGROUP). BPCS-Steganography (Bit-Plane Complexity Segmentation Steganography) is a new steganographic technique invented by Eiji Kawaguchi.

A General feature of the complexity histogram of a “natural image” bit-plane An example is here. Details of the vessel image file format e. Watermarking and Steganography Watermarking is a technique to embed some symbol data or evidence data in some valuable data such as an image, voice, music, video clip, etc. This is based on our security policy. Graphical User Interface knowledge to make a “user-friendly” program.
BPCS-Steganography – Wikipedia
So, the requirement and the objective of watermarking and steganography are very opposite even if they belong to the same information hiding technique.
But, the embedded data can be fragile rather than robust. An issue arises where the data to be embedded appears visually as simple information, if this simple information replaces the complex information in the original image it sfeganography create spurious ‘real image information’. An illustration is here.
The followings are some of the examples.
Invitation to BPCS-Steganography
Nature of the human vision system and information embedding Each bit-plane can be segmented into “shape-informative” and “noise-looking” regions . Retrieved from ” https: How you can outwit steganalysis It is practically impossible to make a compatible program with some given BPCS-Steganography program even if the embedding and extracting operations look the same.
Steganography Steganography tools Steganographic file system Steganography detection. A shape-informative region consists of simple patterns, while a noise-looking region consists of complex patterns . If you are not a researcher, but are very much interested in knowing what a steganography program is, then you can also download and use it for try.
It should be better destroyed by attacking than robust enough to stay long. Bit-Plane Decomposition of a Multi-Valued Image A multi-valued image P consisting of n-bit pixels can be decomposed into a set of n binary pictures. However, if you look carefully, two same-looking areas are entirely different in their sand particle shapes.
The most important feature is a large embedding capacity. We intended to release this program for academic evaluation use. As far as the Web version “Qtech-HV v” is concerned, we bpce up a “90 days validity” mechanism on the embedding part of the program. BPCS-Steganography is absolutely different from traditional techniques. The Human visual system has such a special property that a too-complicated visual pattern can not be perceived as “shape-informative.
Reference  and  are good articles to blcs the details of BPCS embedding algorithm.
Therefore, it is impossible for someone to steal steagnography. Conference VolumeNovember 01, However, we haven’t heard of any report telling “We finally made it completely! It is also reported that we can replace each noise-looking region with another noise-looking patterns without changing the overall image quality. From Wikipedia, the free encyclopedia.
The embedding operation in practice is to replace the “complex areas” sheganography the bit planes of the vessel image with the confidential data. How the complexity histogram changes after the embedding operation.
As far as the bit-planes of a natural image are concerned, complexity  of each bit-plane pattern increases monotonically from the MSB P 1 to the LSB P n. The external data is just a dummy. This page was last edited on 4 Juneat In this case the data is passed through a [binary image conjugation transformation], in order to create a reciprocal complex representation. Complexity histograms of a non-compressed and a compressed file in general See some examples.
Retrieved 3 April When you want to implement your original BPCS-Steganography program, you need to tackle varieties of detailed algorithm before you start working on it. While in steganography, the embedding capacity should be large enough. Utilize the quantization error of the vessel image for a place to hide secret data However, all these methods have a relatively small data hiding capacity. P R4 is mixed with both shape-informative and noise-looking regions.
It is downloadable from other page. Views Read Edit View history. Such topics include, but not all, the followings. B Complexity histograms of a non-compressed and a compressed file in general See some examples. References  Eiji Kawaguchi, et al: This is because the embedded data is secret. It replaces complex areas on the bit-planes of the vessel image with other complex data patterns i.
BPCS-Steganography makes use of this nature of the human vision system. It protects the original data from alteration. E Details of the vessel image file format e.
