Abstract
A method for enhancing detection of fraudulent authentication data is provided that includes obtaining within a window of time from one or more sensors a plurality of signals. Each signal includes data for a biometric modality of a person. Moreover, the method includes determining whether the biometric modality data in the obtained signals was captured contemporaneously. If so, a feature vector is computed for the biometric modality data in each of the plurality of signals, each feature vector is encoded into a corresponding qubit register using an encoding algorithm, and a multi-qubit entangled state is generated from the qubit registers. An entanglement indicator value is also generated for the multi-qubit entangled state and the entanglement indicator value is compared against a threshold value. When the entanglement indicator value satisfies the threshold value, the obtained biometric modality data is determined to be of a live person.
