The Public Eye

In 2011, the Indian government launched a massive programme to collect the iris patterns and fingerprints of all of its 1.2 billion citizens within three years. The numbers associated with the project are staggering. To date, more than 540 million people have enrolled in the optional programme, with one million more joining every day across 36,000 stations operated by 83 agencies. Each new iris pattern must be checked against every other pattern in the database to detect and prevent duplication: this equates to almost 500 trillion iris comparisons each day. Apart from its scale, what makes UIDAI (Unique Identification Authority of India) different is its purpose. It is not a security exercise or a means to control national borders, but a social development programme whose stated aim is ‘to give the poor an identity’.


The algorithms that make iris recognition possible have been developed in the University of Cambridge laboratories. The algorithms, which were patented in 1994 and have been licensed to several companies around the world over the past two decades, are still the basis of all significant iris recognition deployments. The question of whether anyone has the right to be anonymous has been debated for hundreds of years, but it is just as relevant today as it was in the 18th century. The thought of large-scale data collection by governments is a cause for concern: digital identity schemes in the UK and elsewhere have been scrapped due to questions around data protection and the right to anonymity. But in India, anonymity is a huge problem. Just 4% of Indians have a passport, and fewer than half have a bank account.
