Digital Wallet Tiered Document Access via Credential Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital wallets lack secure and efficient mechanisms for tiered access to sensitive documents, often relying on binary authentication methods that do not adequately manage varying levels of document sensitivity.
Innovation Solution
A digital wallet system that generates a document package with a subject document and authentication stamp, allowing users to access different portions of the document based on credential levels, providing minimal, intermediate, or full access depending on user authentication, and enabling secure transfer of document portions to external entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If binary authentication methods are used in digital wallets, then the system is simple to operate, but it cannot adequately manage varying levels of document sensitivity
Solution Approach 1:
The patent segments document access into multiple portions (first portion, second portion, etc.) that can be selectively disclosed based on credential levels. The authentication system is also segmented into multiple credential levels (first level, second level, etc.), allowing progressive access to document portions without requiring full authentication for all information.
Solution Approach 2:
The patent adds a new dimension to authentication by introducing multiple credential levels beyond simple binary authentication. This creates a hierarchical structure where authentication strength determines the extent of document access, transforming a one-dimensional yes/no authentication into a multi-dimensional system with varying degrees of access.
2Ease of operation
If full document access is provided to authenticated users, then user convenience is improved, but document security is compromised
Solution Approach 1:
The patent applies local quality by providing different levels of access to different portions of the same document based on the user's credential level. Instead of uniform full access or uniform no access, the system selectively discloses specific document portions (first portion, second portion, etc.) matched to the authentication strength, ensuring each user receives appropriate access without excessive information.
3Reliability
If multiple authentication levels are implemented, then document security is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamics by making the document disclosure dynamic and adaptive based on the user's credential level. The system automatically adjusts which document portions are disclosed without manual intervention, transforming a static all-or-nothing access model into a dynamic system that responds to authentication strength.
Solution Approach 2:
The system performs self-service by automatically determining the appropriate document portion to disclose based on the credential level provided. The digital wallet system autonomously matches authentication strength with document access rights without requiring manual configuration or intervention, simplifying the user experience despite the complex underlying security architecture.
Data Source
AI summary
A digital wallet system comprises a document originator server and a user device. The document originator server is configured to generate a subject document including a first portion and associate an authentication stamp to form a document package. The document originator server is further configured to send the document package to a user. The user device corresponds to the user. The user device is configured to receive the document package and store the document package in a digital wallet. The user device is further configured to receive, from the user, a request to access the subject document, as well as a credential indication. The user device will provide, to the user, access to only said first portion of the subject document based upon a credential level of the credential indication.
