Aadhaar is an Orwellian project that is unconstitutional and deserves to be scrapped. But Supreme Court has been dragging its feet and giving unreasonable time to Indian government to force Aadhaar upon maximum number of Indians.
Once the biometric have been blocked and Aadhaar is delinked from all government and private services, ask UIDAI, Indian government and Supreme Court to destroy your biometric to prevent any future misuse of the same.
Cyber security of Aadhaar and its biometric database is very poor by design and implementation. It is better to safeguard you interests, including your civil liberties, than being sorry in future. So start blocking your biometric at UIDAI, delink Aadhaar from all services and demand for destruction of biometric from all places.
The Constitution of India and your Fundamental Rights empower you to take all these actions. Neither Indian government nor Supreme Court of India can restrict you from doing above mentioned three activities of blocking, delinking and destruction of biometric database of Aadhaar.
