Facial recognition frictionless access control

A method comprising:

• receiving, from a camera, an image of two or more subjects approaching an access point;
• identifying a subject based on the image;
• identifying at least one additional subject based on the image;
• determining movement information regarding the subject and the at least one additional subject;
• determining a likelihood of risk of tailgating by the at least one additional subject based on information specifying whether the subject is expected to be accessing an access point at a particular time period, and whether the subject will be accompanied by one or more unknown subjects;
• determining whether the at least one additional subject has permission to move through an access point based on the subject, the at least one additional subject, the movement information, and the likelihood of risk of tailgating;
• and
• permitting or denying access movement of the subject or the at least one additional subject through the access point based on whether the at least one additional subject has permission.

A non-transitory computer-readable device having instructions thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• receiving, from a camera, an image of two or more subjects approaching an access point;
• identifying a subject based on the image;
• identifying at least one additional subject based on the image;
• determining movement information regarding the subject and the at least one additional subject;
• determining a likelihood of risk of tailgating by the at least one additional subject based on information specifying whether the subject is expected to be accessing an access point at a particular time period, and whether the subject will be accompanied by one or more unknown subjects;
• determining whether the at least one additional subject has permission to move through the access point based on the subject, the at least one additional subject, the movement information, and the likelihood of risk of tailgating;
• and
• outputting, via an alarm device, an indication of a tailgating event based on the at least one additional subject not having permission.
