India's Supreme Court has ruled that the nation's constitution gives its citizens a right to privacy, a decision that clouds the future of the country's Aadhaar biometric identification scheme.

Aadhaar will see every Indian citizen identified by a 12-digit number after a process that sees their faces photographed, along with a record taken of their irises and fingerprints. The scheme also requires that ID number to be provided to third parties like financial institutions. India's already made use of Aadhaar compulsory for e-government services, part of the country's modernisation drive.
