A blind steganalysis algorithm for JPEG images
Lei Hu · Electronic Design Engineering · 2012
A blind steganalysis algorithm for JPEG images was proposed.The algorithm calculates a total of 15 characteristic parameters from each JPEG image,and using LS-SVM classifier to classify cover and stego images,which can apply to blind steganalysis.The experiments results show that,the algorithm has good performance in both detection rate and computation speed,and it is also reliable to steganalysis for all kinds of JPEG images steganography.
