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.

Digital steganography can hide confidential data i. Most of the LSB planes look like random pattern. 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.

B Complexity histograms of a non-compressed and a compressed file in general See some 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.

We intended to release this program for academic evaluation use. BPCS-Steganography makes use of this property. An image data not having this property will be an artificially processed data. When you want to implement your original BPCS-Steganography program, you need to tackle varieties of detailed algorithm before you start working on it. 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.

Invitation to BPCS-Steganography

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. All articles with unsourced statements Articles with unsourced statements from April Stebanography, we haven’t heard of any report telling “We finally made steganograpgy completely! Views Read Edit View history. It replaces complex areas on the bit-planes of the vessel image with other complex data patterns i.


The Human visual system has such a special property that a too-complicated visual pattern can not be perceived as “shape-informative.

Figure 1 illustrates a couple of PBC bit-planes of a true color image i. BPCS-Steganography makes use of this nature of the human vision system. This page was bpsc edited on 4 Juneat A General feature of the complexity histogram of a “natural image” bit-plane An example is here. By using this site, you agree to the Terms of Use and Privacy Policy.

It is downloadable from other page. BPCS-Steganography and traditional image-based steganography The most traditional image-based steganographic algorithms are as follows.

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. However, if you look carefully, two same-looking areas are entirely different in their sand stegnaography shapes.

It should be better destroyed by attacking than robust enough to stay long.

Steganographic file system Steganography detection. Retrieved 3 April So, the requirement and the objective of watermarking and steganography are very opposite even if they belong to the same information hiding technique.

Such topics include, but not all, the followings. Graphical User Interface knowledge to make a “user-friendly” program.

It is also reported that we can replace each noise-looking region with another noise-looking patterns without changing the overall image quality.


Complexity histograms of a non-compressed and a compressed file in general See some examples. The steganogdaphy data is just a dummy.

References [1] Eiji Kawaguchi, et al: While in steganography, the embedding capacity should be large enough. P R4 is mixed with both shape-informative and noise-looking regions. The embedding operation in practice is to replace the “complex areas” on the bit planes of the bbpcs image with the confidential data.

This is because the embedded data is secret. C How the complexity histogram changes after the embedding operation. But, the embedded data can be fragile rather than robust. BPCS-Steganography is absolutely different from traditional techniques. blcs

The most important feature is a large embedding capacity. Nature of the human vision system and information embedding Each bit-plane can be segmented into “shape-informative” and “noise-looking” regions [2][3].

Retrieved from ” https: Conference VolumeNovember 01, The followings are some of the examples.


General feature of the complexity histogram of a “natural image” bit-plane An example is here. Steganography Steganography tools Steganographic file system Steganography ateganography. Therefore, it is impossible for someone to steal it. E Details of the vessel image file format e. How the complexity histogram changes after the embedding operation.

As far as the bit-planes of a natural image are concerned, complexity [2] of each bit-plane pattern increases monotonically from the MSB P 1 to the LSB P n.
