Cybercrime investigators in Coimbatore say inconsistencies in access to Aadhaar-linked information are hampering efforts to trace offenders as online fraud cases rise across the country.

While banks and telecom companies are permitted to use Aadhaar details for KYC processes—such as opening bank accounts and verifying SIM cards—police say they do not have a direct legal route to access the same data for routine criminal investigations.

Under existing provisions, Aadhaar-related information can be sought only in limited circumstances, such as national security emergencies with approval from a senior Central government official, or through orders from a High Court judge. However, sensitive biometric data like fingerprints and iris scans are not disclosed due to security concerns.

Police say the restrictions lead to delays in cybercrime cases involving fake SIM cards, identity theft, online banking fraud and “digital arrest” scams, forcing investigators to rely on cooperation from multiple sectors including telecom operators and banks.

Cybersecurity expert Suchitra said Aadhaar-centric personal data theft is increasing, alleging that Aadhaar details are being sold on the dark web for as little as $5. She suggested creating a dedicated, secure police server and a special team with strict controls, with access limited to senior officials, and called for clearer, balanced policies on inter-department data sharing.
