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. 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. Steganographic file system Steganography detection. References  Eiji Kawaguchi, et al: So, if you are a researcher, you can use it free.
Invitation to BPCS-Steganography
It is reported that two regions can be segmented by using a “black-and-white boarder length” based complexity measure .
As far as the bcps of a natural image are concerned, complexity  of each bit-plane pattern increases monotonically from the MSB P 1 to the LSB P n. How you can outwit steganalysis It is practically impossible to make a compatible program with some given BPCS-Steganography program stegangraphy if the embedding and extracting operations look the same.
But, the embedded data can be fragile rather than robust. It protects the original data from alteration. 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.
Therefore, it is impossible for someone to steal it. BPCS-Steganography and traditional image-based steganography The most traditional image-based steganographic algorithms are as follows.
BPCS-Steganography makes use of this nature of the human vision system. Figure 1 illustrates a couple of PBC bit-planes of a true color sheganography i. General feature of the complexity histogram of a “natural image” bit-plane An example is here.
The external data is just a dummy. The most important feature steagnography a large embedding capacity. The embedding operation in practice is to replace the “complex areas” on the bit planes of the vessel image with the confidential data. This form of steganography was proposed jointly by Eiji Kawaguchi and Richard O.
Bbpcs 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. However, if you look carefully, two same-looking areas are entirely different in their sand particle shapes. So, the requirement and the objective of watermarking and steganography are very opposite even if they belong to the same information hiding technique. An issue arises where the data to strganography embedded appears visually as simple information, if this simple information replaces the complex information in the original image it may create spurious ‘real image information’.
All articles with unsourced statements Articles with unsourced statements from April An illustration is here. It replaces complex areas on the bit-planes of the vessel image with other complex data patterns i. When you want to implement your original BPCS-Steganography program, you need to tackle varieties of detailed algorithm before you start working on it. E Details of the vessel image file format e. It should be better destroyed by attacking than robust enough to stay long.
Conference VolumeNovember 01, From Wikipedia, the free encyclopedia. An image data not having this property will be an artificially processed data. BPCS-Steganography makes use of this property. In this case the data is passed through a [binary image conjugation transformation], in order to create a reciprocal complex representation.
Retrieved 3 April However, no change is observed after embedding. Complexity histograms of a non-compressed and a compressed file in general See some examples.
A General feature of the complexity histogram of a “natural image” bit-plane An example is here. This replacing operation is called “embedding. This page was last edited on 4 Juneat In watermarking the “external data” is valuable, but the tseganography data is not so valuable. Reference  and  are good articles to know the details of BPCS embedding algorithm.
Stegnography of the LSB planes look like random pattern. 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. BPCS-Steganography is absolutely different from traditional techniques. It is also reported that we can replace each noise-looking region with another noise-looking patterns without changing the overall image quality.
However, we haven’t heard of any report telling “We finally made it completely! It is downloadable from other page. This is based on our security policy.
