Abstract
The invention relates to the field of biometric authentication, in particular to the field of anti-spoofing. The disclosure relates to methods, apparatuses, devices, material information and computer elements for authorizing a user of a device to perform at least one operation that requires authentication.
Claims30
A device for authenticating a user of the device, wherein the device includes at least one image processor and at least one neural network processor, the device comprising:
- at least one image processor configured to provide one or more pattern light image(s) and to manipulate the one or more pattern light image(s);
- at least one neural network processor configured to authenticate the user based at least on extracted material information from the manipulated pattern light image(s) and an authentication process executed at least in part by the at least one neural network processor;
- wherein the extraction of material information from the manipulated pattern light image(s) is performed by the at least one image processor or the at least one neural network processor.
A method for authenticating a user of a device, wherein the device includes at least one image processor and at least one neural network processor, the method comprising:
- providing one or more pattern light image(s) to the at least one image processor and manipulating the one or more pattern light image(s), wherein the manipulation is executed at least in part by the at least one image processor;
- extracting material information from the manipulated pattern light image(s);
- authenticating the user based at least on the extracted material information and an authentication process executed at least in part by the at least one neural network processor.
An apparatus for authenticating a user of a device, wherein the device includes at least one image processor and at least one neural network processor, the apparatus comprising:
- at least one image processor configured to provide one or more pattern light image(s) and manipulate the one or more pattern light image(s);
- material extractor configured to extract material information from the manipulated pattern light image(s);
- at least one neural network processor configured to authenticate the user based at least on the extracted material information and at least in part execution of an authentication process e.g. for authorizing the user to perform at least one operation on, in relation to and/or triggered by the device that requires authentication.
