This paper focused on the fact that common face recognition technologies, such as door control or mobile phone unlocking, can know the users identity in advance. This paper proposes that when the users identity is provided, the performance of face antispoofing can be improved by using the already registered users image. To implement this, the same feature extractor is applied to the registered image and the current image, and then the concatenated result is applied to a binary classifier that classifies it into live or spoofing. It was confirmed that the accuracy was improved by 3%p compared to the existing method that uses only the current image.
