Technological Approach to Address Deficiencies in UID (Aadhaar)

<i>In order to provide an official identity to every citizen of India, the Department of Information Technology, had proposed an idea of biometric enabled unique identification number (UID). The system preserves the personally identifiable information (PII) of millions of users on a centralized government database, supported by some legacy software, with numerous SPOF (single points of failures). Such a centralized system, containing PII, acts like a honey pot to hackers.</i><i>In a country where 2/3rd of the vulnerable citizens, do not have a bank account, but own a smartphone, echoes the possibility of a mobile based digital identity solution. The blockchain technology, by virtue of its key features like decentralization, persistency, anonymity and auditability, emerges as the most promising one amongst all.</i>
