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.

It protects the original data from alteration. Digital steganography can hide confidential data i.
Invitation to BPCS-Steganography
BPCS-Steganography is absolutely different from traditional techniques. An image data not having this property will be an artificially processed data.
However, we haven’t heard of any report telling “We finally made it completely! The external data is just a dummy. Most of the LSB planes look like random sgeganography. References  Eiji Kawaguchi, et al: When you want to implement your original BPCS-Steganography program, you need to tackle varieties of detailed algorithm before you start working on it.
A General feature of the complexity histogram of a “natural image” bit-plane An example is here. Retrieved from ” https: In watermarking the “external data” is valuable, but the embedded data is not so valuable. Details of the vessel image file format e. This bpcz because the embedded data is secret.
It should be better destroyed by attacking than robust enough to stay long.
All articles with unsourced statements Articles with unsourced statements from April General feature of the complexity histogram of a “natural image” bit-plane An example is here. This replacing operation is called “embedding. How the complexity histogram changes after the embedding operation. An illustration is here.
As far as the Web version “Qtech-HV v” is concerned, we set up a “90 days validity” mechanism on the embedding part of the program. Complexity histograms of a non-compressed and a compressed file in general See some examples.
BPCS-Steganography – Wikipedia
B Complexity histograms of a non-compressed and a compressed file in general See some examples. Reference  and  are good articles to know the details of BPCS embedding algorithm.
Steganographic file system Steganography detection. It is reported that two regions can be segmented by using a “black-and-white boarder length” based complexity measure . 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.
While in steganography, the embedding capacity should be large enough. Conference VolumeNovember 01, Graphical User Interface knowledge to make a “user-friendly” program.
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.
Nature of the human vision system and information embedding Each bit-plane can be segmented into “shape-informative” and “noise-looking” regions .
This form of steganography was proposed jointly by Eiji Kawaguchi and Richard O. A shape-informative region consists of simple patterns, while a noise-looking region consists of complex patterns .
In this case the data is passed through a [binary image bpcx transformation], in order to create a reciprocal complex representation.
Figure 1 illustrates a couple of PBC bit-planes of a true color image i.
