The HAT is a privacy-preserving framework for transacting personal data between Internet apps and services and their users or customers. Applications that are built on the HAT store their users’ personal data in containerised databases that are owned and controlled by the users themselves i.e. the HAT Private ‘Microserver’ Data Account (PMDA). HAT-enabled applications then access that data through ‘data debits’ that give them access in return for the services they provide. Applications can ask for just the right data (e.g. location from 7am - 9am) for the right purpose (e.g. to understand commuting patterns), without HAT users providing identifiers or other information that would compromise their privacy.

The HAT code is publicly available on GitHub.
