Data Analytics for Electronic Monitoring

PROPRIETARY DATA ANALYTICS TOOLS

A key component of Sentinel DNA™, our comprehensive electronic monitoring platform, is a proprietary Point Pattern Analysis tool. This allows users to analyze a participant’s daily routine and quickly identify deviations that may indicate a compliance violation.

Using our GPS point capability, the SentinelDNA platform is able to accurately track and display a participant’s whereabouts 24/7. Although this is provided as part of our standard GPS tracking service, the key advantage PPA offers is that it will display, in detailed chart format, the periods of time when an offender was at a certain location. The software is then able to track which locations the participant frequented and the quantity/duration of those visits. This allows for easy determination between the regular routine stops by a participant and those derivations that may be in restricted locations.

As shown below in Figure 1, Point Pattern Analysis analyzes locations frequented by each individual participant enrolled in a program. Locations where a participant spends significant periods of time are identified and labeled as known locations and are depicted as such on DNA maps. For ease of review, the corresponding times spent at these locations are depicted on a bar graph. All known locations are identified with a unique color system, while locations that are new for the offender are color-coded in RED. To make the analysis of a participant’s activity easier, DNA allows users to add labels to the locations that a participant visits as part of their daily, weekly or monthly routine (e.g., work, church, counselor’s office, etc.).
