A Score-Level Fusion of Fingerprint Matching With Fingerprint Liveness Detection
IEEE Access, 2020 Fingerprint-based recognition is widely deployed in different domains. However, the traditional fingerprint recognition systems are vulnerable to presentation attack, which utilizes an artificial replica of the fingerprint to deceive the sensors. In such

A Behavioral-Based Fingerprint Liveness and Willingness Detection System
Applied Sciences, 2022 Fingerprints have been used for decades to verify the identity of an individual for various security reasons. Attackers have developed many approaches to deceive a fingerprint verification system, ranging from the sensor level, where gummy fingers are ...

Complexity of Liveness in Parameterized Systems [PDF]
, 2019 We investigate the fine-grained complexity of liveness verification for leader contributor systems. These consist of a designated leader thread and an arbitrary number of identical contributor threads communicating via a shared memory.

Towards liveness detection in keystroke dynamics: Revealing synthetic forgeries
Systems and Soft Computing, 2022 While the accuracy of keystroke dynamics verification systems has traditionally been evaluated using a zero-effort attack model, the current trend is to recognize that such an approach is too optimistic.

Monoclonal antibodies that detect live salmonellae [PDF]
Applied and Environmental Microbiology, 1992 Nine immunoglobulin G and nine immunoglobulin M murine monoclonal antibody-producing hybridomas reactive with live Salmonella bacteria were obtained from several fusions of immune spleen cells and Sp2/0 myeloma cells. The antibodies were selected by the magnetic immunoluminescence assay. The monoclonal antibodies were reactive with serogroups A, B, C1,

Efficient Emptiness Check for Timed B\"uchi Automata (Extended version) [PDF]
, 2010 The B\"uchi non-emptiness problem for timed automata refers to deciding if a given automaton has an infinite non-Zeno run satisfying the B\"uchi accepting condition. The standard solution to this problem involves adding an auxiliary clock to take care of
