Abstract: A micropattern detection-based method and system of performing an authentication of video of a person in order to authorize access to a secured resource is provided. The user provides image data in which they present a secondary computing device with a specially fabricated screen cover. The screen cover includes a plurality of micro-holes that collectively provide a unique micropattern. When the user adjusts a display setting, the micropattern, previously cloaked, becomes apparent as an arrangement of pinpoints of light. The system and method are configured to evaluate the image data to determine whether the micropattern is present. If a micropattern is present, the system determines the image is authentic and can verify an identity of the person. In some cases, the system can further be configured to automatically grant the person access to one or more services for which they are authorized.
