PROACTIVE LOSS PREVENTION SYSTEM
A method and system for Proactive Loss Prevention (PLP) System in venue and retail using wireless-based technology. Physical security measures are the first line of defense for protecting assets in any venue and retail spaces. These systems (e.g. Electronic Article Surveillance systems) are widely deployed in retail spaces. However, retail theft is still estimated at a multibillion dollar level on an annual basis in the US alone. This invention augments existing physical security systems to enable a proactive approach for suspect identification and subsequent presence alerting using a wireless local area network (WLAN) based system.
1 . A computer-implemented method comprising:
detecting, with a computer system, one or more mobile devices at a venue;
storing, with the computer system, a set of data, the set of data including a location of detection at the venue of the one or more mobile devices, a unique identifier of the one or more mobile devices, a time of detection at the venue of the one or more mobile devices, an identifier of a corresponding computing device at the venue that detects the one or more mobile devices, and corresponding distance of the one or more mobile devices from the corresponding computing device that detects the one or more mobile devices;
determining, with the computer system, an occurrence of an incident at the venue and a time and location of the occurrence of the incident, and notifying of said occurrence;
determining, with the computer system, a first set of computing devices associated with the location of the occurrence of the incident at the venue based on the notified occurrence of the incident, wherein the first set of computing devices are proximity recognition devices;
generating and storing, with the computer system, an event associated with the occurrence of the incident, the event including the time of occurrence of the incident and information regarding the one or more mobile devices;
determining, with the computer system, whether a first corresponding distance of the one or more mobile devices from the first set of computing devices at the time of the occurrence of the incident is less than a first threshold based on the set of data;
identifying, with the computer system, a first set of the one or more mobile devices corresponding to the event, wherein the first corresponding distance of the first set of the one or more mobile devices from the first set of computing devices at the time of the occurrence of the incident is less than the first threshold; determining, with the computer system, a second set of proximity recognition devices associated with a location of another occurrence of the incident;
generating and storing, with the computer system, another event associated with the other occurrence of the incident;
determining, with the computer system, whether a second corresponding distance of the one or more mobile devices from the second set of proximity recognition devices at the time of the other occurrence of the incident is less than a second threshold based on the set of data;
identifying, with the computer system, a second set of the one or more mobile devices corresponding to the other event, wherein the second corresponding distance of the second set of the one or more mobile devices from the second set of proximity recognition devices at the time of the occurrence of the incident is less than the second threshold;
identifying, with the computer system an intersection of the first set and the second set;
determining, with the computer system, at least one mobile device in the intersection to be a suspect device;
identifying, with the computer system, a suspect associated with the suspect device, wherein identifying the suspect includes associating visits of the one or more mobile devices to the venue with a plurality of images of persons visiting the venue to determine corresponding images of the suspect at the time of the occurrence of the incident and at a location proximate to the occurrence of the incident;
determining, with the computer system, a return of the suspect by detecting a re-visit of the suspect device; and
alerting, with the computer system, a venue operator of the return of the suspect and providing an image of the suspect to the venue operator.
