Abdali, Natiq M., Hussain, Zahir M..  2020.  Reference-free Detection of LSB Steganography Using Histogram Analysis. 2020 30th International Telecommunication Networks and Applications Conference (ITNAC). :1—7.
Due to the difficulty of obtaining a database of original images that are required in the classification process to detect tampering, this paper presents a technique for detecting image tampering such as image steganography in the spatial domain. The system depends on deriving the auto-correlation function of the image histogram, then applying a high-pass filter with a threshold. This technique can be used to decide which image is cover or a stego image, without adopting the original image. The results have eventually revealed the validity of this system. Although this study has focused on least-significant-bit (LSB) steganography, we expect that it could be extended to other types of image tapering.
