Dynamic Imaging, a New Jersey software company founded in 1993, develops CorreTrak, a mobile app for jail management. To help correctional officers verify inmate identities more reliably, Dynamic Imaging integrated FaceMe® SDK into CorreTrak, enabling facial verification through the mobile devices officers already carry.
Correctional officers routinely verify inmate identities as people move between cells and facility areas. RFID wristbands provide a quick way to check identity, but they verify the band, not the person wearing it. If a wristband is transferred to another inmate, the scan may not reveal the discrepancy. Scanning also requires officers to be within close proximity of inmates.
The safety risks are significant. From 2015 to 2019, correctional workers experienced nonfatal workplace violence at an average annual rate of 149.1 incidents per 1,000 workers, more than 18 times the rate for all workers, according to the Bureau of Justice Statistics.¹
Dynamic Imaging needed a way to verify identities by face, make results available to supervisors and monitoring staff in real time, and screen visitors against approved lists within CorreTrak
With FaceMe SDK integrated into CorreTrak, officers can capture an inmate's face using a mobile device and verify the person's identity in real time. Results appear on a live dashboard, allowing supervisors and monitoring staff to follow verification activity as it happens.
CorreTrak also supports visitor screening against approved lists, including visitors such as attorneys and family members. When someone attempting to visit an inmate is not on the applicable list, the app alerts the officer.
FaceMe SDK supports iOS, Android, and Windows, allowing facial verification to fit into CorreTrak rather than requiring a separate application. In the on-premises configuration, a Windows-based server handles face enrollment and matching, while officers use their mobile devices to capture faces and submit verification requests. The enrollment database remains on the server rather than being stored on officers' phones.
FaceMe achieves a 99.83% true accept rate in 1:1 face comparison at a 1-in-1,000,000 false match rate.
Integrating FaceMe into CorreTrak gives correctional facilities a way to verify inmates by face instead of relying solely on wristband scans. Officers can check identities using their existing mobile devices, while supervisors gain visibility into verification activity and staff can flag visitors who are not on approved lists.
By bringing facial verification into a jail management app, Dynamic Imaging makes identity checks a more direct part of routine corrections workflows.
