Abstract :
As the extension of the least significant bits (LSB) steganographic algorithm, steganographic algorithm embedding in two least-significant bits (Two-LSBs for short) has some characteristics, such as visual imperceptibility, higher capacity and easy realization. A new steganalysis method is introduced to detect the existence of hidden message that are randomly embedded in LSB and the second significant bits (second-LSBs)of image pixels. It is proposed based on investigating the statistical characters of image data in LSB and the second significant bits with hidden message. It can estimate embedding rate and length of hidden message. The experiments present detection effect with different thresholds and embedding rates, and show the detection method is effective that detection rate is up to 90% when embedded rate is more than 20%.
