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.

Such topics include, but not all, the followings. So, the requirement and the objective of watermarking and steganography are very opposite even if they belong to the same information hiding technique. The followings are some of the examples.
This is based on our security policy. While in steganography, the embedding capacity should be large enough. A shape-informative region consists of simple patterns, while a noise-looking region consists of complex patterns .
We intended to release this program for academic evaluation use. It is also reported that we can replace each noise-looking region with another noise-looking bpcw without changing the overall image quality.
In this case the data is passed through a [binary image conjugation transformation], in order to create a reciprocal complex representation.

In watermarking the “external data” is valuable, but the embedded data is not so valuable. B Complexity histograms of a non-compressed and a compressed steganogralhy in general Stteganography some examples. How the complexity histogram changes after the embedding operation.
If you are not a researcher, but are very much interested bpvs knowing what a steganography program is, then you can also download and use it for try. An illustration is here.
BPCS-Steganography – Wikipedia
From Wikipedia, the free encyclopedia. Details of the vessel image file format e. This form of steganography was proposed jointly by Eiji Kawaguchi and Richard O.
Views Read Edit View history. The Human visual system has such a special property that a too-complicated visual pattern can not be perceived as “shape-informative.
BPCS-Steganography and traditional image-based steganography The most steganpgraphy image-based steganographic algorithms are as follows. Bit-Plane Decomposition steganogrwphy a Multi-Valued Image A multi-valued image P consisting of n-bit pixels can be decomposed into a set of n binary pictures.
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. This page was last edited on 4 Juneat It is reported that two regions can be segmented by using a “black-and-white boarder length” based complexity measure .
BPCS-Steganography makes use of this nature of the human vision system. The embedding operation in practice is to replace the “complex areas” on the bit planes of the vessel image with the confidential data. It is downloadable from other page. References  Eiji Steganofraphy, et al: But, the embedded data can be fragile rather than robust.
BPCS-Steganography is absolutely different from traditional techniques. The most important feature is a large embedding capacity. Digital steganography can hide confidential data i. However, no change is npcs after embedding. Retrieved 3 April Nature of the human vision system and information embedding Each bit-plane can be segmented into “shape-informative” and “noise-looking” regions .
An image data not having this property will be an artificially processed data. It should be better destroyed by attacking than robust enough to stay long. C How the complexity histogram changes after the embedding operation. It replaces complex areas on the bit-planes of the vessel image with other complex data patterns i. Complexity histograms of a non-compressed and a compressed file in general See some examples.
