Facial recognition frictionless access control

An access control method, comprising:

• detecting, by a camera of at least one computing device of an access control system, an image regarding a subject;
• enabling, by a data communications device of the at least one computing device, communication with a mobile device associated with the subject;
• maintaining by a database of the at least one computing device, facial information regarding a plurality of subjects;
• executing, by a processor of the at least one computing device, an identification algorithm to identify a subject based on the detected image and the facial information maintained by the database;
• identifying, by the processor, at least one additional subject based on the detected image;
• determining, by the processor, movement information regarding the subject and the at least one additional subject;
• performing, by the processor, one or more second factor authentication processes;
• determining, by the processor, 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 a likelihood of risk of tailgating;
• and
• granting, by the processor, access to the at least one additional subject via the access point based on the permission and whether one or more of the identification algorithm or the one or more second factor authentication processes are determined be successful.
