This system requirement directs the researchers towards the watermarking algorithms which provide security, authentication, imperceptibility and robustness.
The issues of interest are: image quality after watermark embedding, robustness of authentication bits to JPEG compression, authentication sensitivity to malicious manipulation such as crop-and-replace, as well as widely-used but not directly oriented image processing methods such as low pass and median filtering, noise, brightness and contrast change, etc.
By integrating beat-based segmentation, mid-level chroma feature, and fuzzy authentication, we obtain high robustness against acceptable operations and fragility under malicious modifications at the same time.
The law does not specify particular methods of preprogramming passwords or generating means of authentication, nor does it specify robustness, such as minimum complexity requirements, for passwords.
The same should be ascertained for better robustness of security and authentication even if the watermarked image experiences geometrical or any non-geometrical attacks.
We identify Zernike moments of the image to generate feature vector and demonstrate its good robustness and discriminative capability for authentication.
The proposed protocol for key management ensures security in the form of authentication, integrity, confidentiality, protection against replay attacks, and robustness across reboots.
Or Samsung is not entirely confident in the robustness of its own facial biometric authentication systems — which have previously been shown to be pretty trivially fooled.
While the latter properties are prohibitive for the use of JPEG2000 PBHash in the content search scenario, these specific robustness limitations are less critical for authentication purposes.
We aim to investigate the potential possibility of using gestures as a signal for biometric system and the robustness of the proposed multimodal user authentication system.
Based on the robustness to distortions, these schemes can be classified into complete authentication and content authentication.
