Frame code based blind fingerprint scheme of anti-CTP attack

CTP attack involves the cropping,translation and pasting attack.This paper provides a frame code based blind fingerprint scheme of anti-CTP attack.This scheme deals with the fingerprint information by fingerprint scrambling and frame coding techniques,which improve the information security and make the synchronization information bind with fingerprint.Additionally,the scheme of image slicing based multi-version embedment and image based effective slicing position extraction is presented.This scheme is robust against the CTP attack.The extraction of fingerprint information does not need any auxiliary information and can resist the normal image operation effectively.
