When you get asked for identification upon entering a bar, the only information the bartender should have access to is your eligibility to buy alcohol. All other information on a typical driver's license or passport, such as the ID number, place of residence, and exact date of birth, are not relevant for this particular age verification. In almost all cases, a physical ID carries more information than what you want to share, since in most cases the requesting party is only interested in very specific elements of your identification. For example: Are you eligible to buy alcohol? What is your state of residence? Are you a citizen? Can you verify your home address? The requesting party is always interested in a set of information as opposed to all your personal information. Additionally, having a physical ID with you at all times is both inconvenient and carries a high probability of being misplaced or stolen, resulting in identity theft. We believe that digital identification can solve this issue of proving your identification without sharing any more details than are required.
Using Hedera Hashgraph, we have created the PrivacyProtect app to demonstrate how digital identification would work in the future. Users will need to provide identifying documents to a government agency (like the Department of Motor Vehicles) or any approved agency that can validate identity. The agency will use an app like PrivacyProtect to create a digital identification profile for the user, who will have complete control over what they want to share. Upon successful verification by the agency, the app will generate a unique set of QR codes for each user. This set of QR codes represents different identification attributes, such as age and proof of residence. The codes can be shared with the requesting party looking to verify a specific information about the user. To illustrate this with our earlier example, if a user needed to verify their age to enter a bar, the bartender would use the PrivacyProtect mobile/tablet app to scan the user’s QR code. On a successful scan, the app will display the users photo and a simple “yes” or “no” on the bartenders mobile app verifying if the user is eligible to buy alcohol.
