Large-scale steganalysis using outlier detection method for image sharing application

摘要: In past several years so many steganalysis techniques are emerged but none of them not efficient for real world image sharing applications where millions images transmitted. small scale individual detected suspicious payload. Here uses a different approach to determine most prolific steganographer who sends large volume secret data in the network. A new technique is introduced out number users, each user transmits numerous images. this method steganalytic features extracted from image, distance between users calculated and finding outlier deviate majority other users.
