Assignee: ID R&D INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The method of claim 1, wherein computing the anti-spoofing confidence score comprises:
extracting, from the signal, a Fast Fourier Transform (FFT) feature and feeding said FFT feature to a first pre-trained deep neural network of the at least one pre-trained neural network to assign a first confidence score of the at least one confidence score to the signal;
extracting, from the signal, a Discrete cosine transform (DCT) feature and feeding said DCT feature to a second pre-trained deep neural network of the at least one pre-trained neural network to assign a second confidence score of the at least one confidence score to the signal;
applying a pre-trained deep convolutional network (DCN) of the at least one pre-trained neural network based on an end-to-end architecture to the signal to assign a third confidence score of the least one confidence score to the signal;
computing the anti-spoofing confidence score based on the first confidence score, the second confidence score and the third confidence score.
