Source Code for Dynamic Pattern-Based Image Steganography (DPIS) Technique

DYNAMIC PATTERN BASED IMAGE STEGANOGRAPHY (DPIS) TECHNIQUE In this section Dynamic Pattern based Image Steganography technique (DPIS) was discussed in detail. The idea behind our technique is that dominant color or Significant color in a pixel should not suffer from data embedding while the insignificant color channel can be used for data embedding. Figure 1 and Figure 2 depicts the embedding and extracting process of DPIS. Major steps in the DPIS technique  Generate the random string of length say ‘N’ in terms of R, G and B. From the generated indicator sequence, choose the indicator channel and check whether the indicator channel is the lowest among the other channels. If Indicator is lowest, then skip the pixel from embedding else embed the data.  Choose the data channel from the remaining two channel  The number of bits to be embedded in data channel is determined at run time and it is not pre determined. At the extraction part, channel in which data is embedded is commuinicated in the LSB of Indicator channel.  The indicator sequence should be obtained from the embedding part.  If the LSB of Indicator channel is ‘0’, the channel follows immediately after the indicator is the data channel  If the LSB of Indicator channel is ‘1’ , the channel precedes the indicator is the data channel To extract the exact number of bits embedded in data channel we need to know  If the LSB of third channel is ‘0’, then three bits of data are embedded in data channel  If the LSB of third channel is ‘1’ , the four bits of data are embedded in data channel DPIS technique has been tested on different image category such as portrait, flower, nature, toys etc. Figure 3 to Figure 5 shows the Cover and Stego images generated through DPIS technique.
