Safe step

Abstract

Court orders may require supervising agencies (probation, parole, pre-trial or law enforcement) to monitor a specific set of offenders using ankle bracelets. These ankle bracelets transmit the offender's GPS coordinates at regular intervals. The analysis of the offender's GPS data help: (1) detect unauthorized activities in real time and provide alerts to a community corrections officer, law enforcement dispatcher or a control center, and (2) mine for the offenders' suspicious behavior and predict probable future threats beforehand. Unauthorized activities include protecting geographically defined regions (e.g., school zones) in which the offender is not allowed to be present. Suspicious behaviors include the meeting of offenders with each other on a regular basis, possibly near restricted zones.
