Selective Verified Attribute Exchange via Biometric Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for information sharing between individuals in physical proximity lack verification and selective disclosure capabilities, as physical credentials are inflexible, difficult to alter, and prone to forgery, while verbal exchanges lack credibility.
Innovation Solution
Mobile computing devices securely transmit verified attributes using short-range wireless protocols, broadcasting biometric information verified by a trusted service, allowing contextual and selective sharing based on environment and recipient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical credentials (IDs, transcripts, bank statements) are used to verify attributes, then third-party verification of attributes is achieved, but the information cannot be selectively shared and all printed information is disclosed
Solution Approach 1:
The patent segments credentials into individual verifiable attributes (e.g., name, degree, employment history, financial status) that can be independently selected and shared. Instead of disclosing entire physical documents, the system extracts specific attribute claims and verifies them individually through cryptographic proofs, allowing selective disclosure while maintaining verification credibility.
Solution Approach 2:
The patent extracts specific attribute claims from complete credentials and separates them into discrete verifiable statements. Each attribute claim can be independently verified and shared without revealing other attributes. This extraction allows users to present only the necessary information for a given context while maintaining the integrity of the original credential verification.
2Reliability
If detailed credentials (transcripts, bank statements) are carried to provide comprehensive verification, then more attributes can be verified, but the credentials are difficult to alter or forge and present the same selective sharing difficulties
Solution Approach 1:
The patent creates digital copies of credential data in the form of structured attribute claims with cryptographic proofs. These digital representations can be easily transmitted and verified without requiring the physical credential documents themselves. The system uses verifiable credentials and zero-knowledge proofs to replicate the verification function of physical credentials while enabling digital selectivity and ease of management.
Solution Approach 2:
The patent transforms static physical credentials into dynamic digital attribute claims that can be selectively presented, updated, and managed programmatically. Users can dynamically choose which attributes to share based on context, and the system can automatically verify and validate attributes without manual intervention. This dynamic approach replaces rigid physical document handling with flexible digital credential management.
3Ease of operation
If verbal exchange of information is used, then information sharing is simple and quick, but there is no way to verify truthfulness and people may exaggerate or be dishonest
Solution Approach 1:
The patent introduces a trusted verification service as an intermediary that issues verifiable credentials and proofs. Instead of direct verbal claims between parties, the verification service mediates by providing cryptographic evidence that attests to the truthfulness of attribute claims. This intermediary layer maintains the simplicity of digital exchange while adding robust verification through third-party-issued verifiable credentials.
4Reliability
If physical credentials are used, then some attributes are verified, but the information is pre-printed and cannot be redacted or selectively shared based on context
Solution Approach 1:
The patent transforms static physical credentials into dynamic digital attribute claims that can be selectively presented based on context. Users can programmatically determine which attributes to share with which parties in different situations. The system supports contextual policies that automatically control attribute disclosure, enabling the same verified credentials to adapt to different social and professional contexts without requiring physical document manipulation.
Data Source
AI summary
A first mobile device securely transmits selected verified attributes concerning the corresponding user to a second mobile device. The first device broadcasts verified, signed biometric information concerning its user, and the user's public key. The second device confirms the received broadcasted biometric information, based on sensor input. For example, sensors on the second device generate images of the first user, who is physically proximate, and information gleaned from the images is compared to broadcasted biometric information. In response to confirming the broadcasted biometric information, the second device transmits a request to establish a secure channel, and both devices generate a session key. The first device selects specific verified attributes to provide to the second device, based on context, policy and/or user directive. The first device then encrypts the attributes using the session key, and transmits them to the second device. The second device receives and decrypts the attributes.
