Method of host-directed illumination and system for conducting host-directed illumination

An authentication computer system for detecting user liveness comprising:

• a processor;
• and
• a memory for storing data, said authentication computer system being associated with a network and said memory being in communication with said processor and having instructions stored thereon which, when read and executed by said processor cause said authentication computer system to:
• transmit an illumination instruction to a computing device, the illumination instruction comprising a plurality of illumination instructions that each cause illumination to be applied for a different wavelength;
• receive a plurality of images included in a sequence of discrete images, each discrete image being captured by the computing device while illumination is applied to the face of a user in accordance with the illumination instruction;
• recognize reflections in the plurality of images, the reflections resulting from the applied illumination;
• and
• determine the facial image data was taken of a live person based on the reflections.

A method for detecting user liveness comprising:

• capturing, by a computing device, facial image data of a user as a sequence of discrete images, each discrete image being captured while illumination is applied to the face of the user in accordance with an illumination instruction comprising a plurality of illumination instructions that each cause the applied illumination to be for a different wavelength;
• recognizing, by the computing device, reflections in a plurality of the images, the reflections resulting from the applied illumination;
• and
• determining, by the computing device, the facial image data was taken of a live person based on the reflections.

A computing device for detecting user liveness comprising:

• a display screen;
• a processor;
• and
• a memory configured to store data, said computing device being associated with a network and said memory being in communication with said processor and having instructions stored thereon which, when read and executed by said processor cause said computing device to:
