Providing a truckload of documents as proof of identification can be a painful experience every time you want a loan or want to open an account in a bank. So what if a bank could automatically identify you every time you walk in for a service. This could soon be a reality thanks to Bengaluru-based start-up, Bitgram. The firm uses machine learning and blockchain technology to create what it calls 'SuperIdentity' — your digital DNA and what’s more, it also protects you from identity theft.
