This study deals with constructing and implementing new algorithm based on hiding a largeamount of data (image, audio, text) file into color BMP image. We have been used adaptive imagefiltering and adaptive image segmentation with bits replacement on the appropriate pixels. These pixelsare selected randomly rather than sequentially by using new concept defined by main cases with theirsub cases for each byte in one pixel. This concept based on both visual and statistical. According to thesteps of design, we have been concluded 16 main cases with their sub cases that cover all aspects of theinput data into color bitmap image. High security layers have been proposed through three layers tomake it difficult to break through the encryption of the input data and confuse steganalysis too. Ourresults against statistical and visual attacks are discussed and make comparison with the previousSteganography algorithms like S-Tools. We show that our algorithm can embed efficiently a largeamount of data that has been reached to 75% of the image size with high quality of the output. |
