Story highlights

Tamil Nadu Police has launched Spectrum, a colour-coded system to profile, classify and monitor sexual offenders based on risk. Here's how it works.

Tamil Nadu Police has launched a new initiative called ‘Spectrum’ to track and monitor sexual offenders on the basis of their level of risk. Spectrum is an abbreviation for Sexual Offender Profiling, Evaluation, Classification, Tracking, Risk Assessment and Unified Monitoring System. According to TOI, the project covers 10 districts in the state's Southern Police Zone, Madurai, Tirunelveli, Thoothukudi(Tuticorin), Kanyakumari, Virudhunagar, Dindigul, Theni, Ramanathapuram, Sivagangai and Tenkasi. It is spearheaded by the South Zone Inspector General of Police.

According to Tamil Nadu Police, the region records 1500 to 2000 cases of sexual offence annually, including cases of marital rape or relationship or marriages where consent is present, while many of those include stalking, voyeurism, harassment and sexual trafficking.

What is Spectrum?

Spectrum collects comprehensive biometric data using Measurement Capturing Units. It organises offenders into specific colour categories to streamline police monitoring and investigation, based on the alleged offence and the likelihood of reoffending. The operational features of Spectrum have fingerprints, palm prints, iris scans, physical measurements, and high-resolution photographs of 15,000 individuals in cases ranging from stalking and harassment to rape and murder. It also enables digital surveillance of suspects' mobile devices and social media footprints.
