Identity Escrow System for Selective Disclosure and Access Notification

The identity information is segmented into multiple components (e.g., name, address, date of birth, photo) that can be selectively disclosed. The system allows users to present only the specific attributes needed for verification (such as age proof) without revealing the complete identity profile, thus resolving the contradiction between verification reliability and information privacy.

The patent extracts only the necessary verification attributes from the full identity information and separates them from unnecessary personal details. By taking out only the required information (e.g., extracting age verification capability while leaving address and other sensitive data undisclosed), the system enables reliable verification without compromising privacy.

The system implements a feedback mechanism where escrow providers are notified when verifiers access identity information held in escrow. This notification feedback loop ensures users are informed about who accesses their information and when, maintaining accountability while preserving ease of access through the escrow service.

The escrow service acts as an intermediary between the user and the verifier. Instead of users directly storing and managing their own identity information, the escrow provider holds the information securely and mediates access requests from verifiers, thereby maintaining ease of access while introducing accountability through controlled and monitored access.

The system dynamically adjusts the level of information disclosure based on the specific verification requirements. Rather than a static disclosure policy, the system allows flexible, context-dependent disclosure where users can reveal different levels of detail (minimal information for low-risk verifications, more comprehensive information for high-risk verifications), thus balancing privacy with verification capability.

The patent changes the parameter of information disclosure from fixed to variable. Users can modify the disclosure parameters (e.g., disclosing only age instead of full birthdate, or providing additional attributes when needed) based on the verification context, enabling the system to adapt between privacy preservation and verification capability requirements.
