Publication number: 20230419058Abstract: A computer-implemented system and method for entity tracking and identification is provided. A tracker associated with an entity is tracked. Communication is continuously attempted between the tracker and a tracking device associated with an individual in custody of the entity. During one of the attempted communications, an absence of the tracker is determined by identifying a time of the attempted communication and applying a time threshold to the time for the attempted communication. The absence of the tracker is identified when no communication has been established with the tracking device within the time threshold. The entity is classified as missing when the absence of the tracker is determined.Type: ApplicationFiled: May 26, 2023Publication date: December 28, 2023Inventors: Felicia Linn, Ramkumar Abhishek, Ashish V.
