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.

An issue arises where the data to be embedded appears visually as simple information, if this simple information replaces the complex stegznography in the original image it may create spurious ‘real image information’.

Therefore, it is impossible for someone to steal it. However, we haven’t heard of any report telling “We finally made it completely!

This is based on our security policy. We intended to release this program for academic evaluation use. How the complexity histogram changes after the embedding operation. The Human visual system has such a special property that a too-complicated visual pattern can not be perceived as “shape-informative.


Graphical User Interface knowledge to make a “user-friendly” program. Such topics include, but not all, the followings. Details of the vessel image file format e.

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. Nature of the human vision system and information embedding Each bit-plane can be segmented into “shape-informative” and “noise-looking” regions [2][3].

BPCS-Steganography is absolutely different from traditional techniques. A General feature of the complexity histogram of a “natural image” bit-plane An example is here. This replacing operation is called “embedding. All articles with unsourced statements Articles with unsourced statements from April It replaces complex areas on the bit-planes of the vessel image with other complex data patterns i.

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.

BPCS-Steganography – Wikipedia

P R4 is mixed with both shape-informative and noise-looking regions. A shape-informative region consists of simple patterns, while a noise-looking region consists of complex patterns [3].

However, no change is observed after embedding. An image data not having this property will be an artificially processed data.

It protects the original data from alteration. Views Read Edit View history.


Digital steganography can hide confidential data i. The external data is just pbcs dummy. In watermarking the “external data” is valuable, but the embedded data is not so valuable. This is because the embedded data is secret. Steganography Steganography tools Steganographic file system Steganography detection. Retrieved 3 April The followings are some of the examples. 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.
