Abstract: The present invention provides a system and a method for biometric authentication using facial information to recognize users across different locations. Further, the system generates feature vectors based on the facial information and generates recognition metadata for the identification and categorization of users. The system utilizes a frame relay (FR) connect pipeline to provide a more economically efficient solution, enable locations with improper bandwidth, and support a large number of locations on the same hardware. The system uses an artificial intelligence (AI) engine for predicting one or more categorizations of the user based on the generated one or more recognition metadata.
