Design Considerations of Ex-post TETs for Credential Transparency
Ex-post Transparency-Enhancing-Technologies aim to help data subjects exercise their right to transparency by providing them with visibility on the sensitive data that is collected, processed, or disclosed to different agents. This project goes through the main design considerations when developing such a tool for digital credential systems, starting from custom-fit secure logging mechanisms, sanitization, querying, monitoring and auditing mechanisms, and external mechanisms that interact with the data subjects.
