Abstract: Digital security threats to computers or smartphones exist in the form of viruses, spywares, or phishing/hacking activities. Smartphone devices, with knowledge of our mobile numbers, have thus become targets of cyber attacks and identity theft. Despite this risk, our personal mobile numbers are collected by many online and offline entities to grant us access to their services and amenities. We propose here a blockchain based solution which provides a virtual ID in lieu of a privacy-aware user’s mobile number. This virtual-ID could then be used for typical services. The solution further consists of a decentralized Android app, blockchain nodes hosted on volunteers’ smartphones which run Ethereum-style smart contracts for typical tasks on the system. Users begin by registering in the app to generate such a virtual ID for a period of their convenience. This proposal contributes to greater privacy awareness towards their IDs that consumers regularly trade-off in favour of behavioural analytics, marketing messages or worse.
