Cloud Multipass proposal
There is a huge redundancy in handling personal information. Every service provider asks for an ID, proof of address, bank details etc. For many people all those details are already stored in their email accounts or smartphone-related storage. What happens is the data is unnecessarily replicated to badly managed business storages of all kind. This also keeps alive lots of redundant IT support businesses.
Large cloud providers together with governments should form a consortium to unify such PII storage types, so the PII can be kept in one or few user-chosen *special provider* storages. Typically those would be Google, Apple, Amazon, Microsoft, but could be other providers certified for well managed security and to stimulate competition. Existing solutions such as Google Drive, S3 etc can be the basis for the service.
Non-provider businesses will not store PII, only basic identifiers, like business-related account number, email and phone number. Each business has to register to access PII super-storage with access logged and users notified on each access. Businesses will pay reasonable fees for each access, which will be a monetary motivator to limit excessive usage, but also will pay for service maintenance. Any business can upload necessary additional data to the storage, but cannot access it later without user authorization. Users will be able to authorize over the smartphone. Documents can have hashes and time stamp to avoid content manipulation.
Identify theft can be eliminated by immediate comparison of personal IDs across consortium providers. For example, instantly alerting if someone uses your passport photo to open an account in your name. Well, intelligence services might dislike the idea for impossibility to issue fake IDs.
