Image-based replication sift paste tamper detection algorithm first extracted sift feature, using a hybrid programming method for extracting sift online offer, then sift feature matching with RANSAC algorithm eliminate mismatch right, and finally with the segment will copy and paste the original block and block matching connect the dots. This calculation algorithm is resistant to various processing operations, such as rotation, scale scaling, adding noise and the like and several combinations.
