authentication

Biometrics
The use of a personal feature—e.g., face, hand, fingerprint, signature, voice, iris, or other highly specific indicator—to verify a person’s identity, and restrict access to private information to authorised persons.

Informatics
Confirmation of a user's identity, generally through a user name and password.

authentication

Biometrics The use of a personal feature, eg, face, hand, fingerprint, signature, voice, iris, or other highly specific indicator to verify a person's identity, and restrict access to information to authorized persons; confirmation of a user's identity, generally through user name and password or biometric characteristics. See Biometrics. Cf Authorization.

The detailed processes of the improved copy-move forgery detection algorithm based on DCT are as follows:
All the images used in the experiments are from the Columbia image-splicing detection evaluation dataset built by Ng and Chang [21], which is intended for testing digital image forensics, or from CoMoFoD, a database for copy-move forgery detection built by Tralic et al.
The three measures are used to evaluate the performance of the copy-move image forgery detection method.
Hence, for the next experiments, we will use Zernike moment of order 10 to analyze the performance of the Curvelet transform and the Wavelet transform in forgery detection in other different perspectives.
Thus, keypoint based forgery detection techniques become unsuccessful if copied and pasted regions do not accommodate keypoints.
Figure 6(c) illustrate the result of SIFT, SURF, and sORB based forgery detection methods in the literature.

In forgery detection, a new hash value is computed from the operated multimedia content, and compared with the stored one.
In this paper, copy-move forgery detection is performed through the DCT and Gaussian RBF kernel PCA using the squared blocks.
It is important that all technologies - including those that have not been applied or tested in production systems -- be evaluated for use in applications that support check forgery detection," Backenroth said.
