Blinded Data Exchange Protocol for Privacy and Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data communications technologies face a conundrum in protecting identity information while ensuring the veracity of the information source, as existing methods to hide identity often compromise trust in the received information.
Innovation Solution
A method and apparatus that utilize a third-party-managed protocol to facilitate data-based activities, including tokenization and encryption, to prevent substantive access to data information, ensuring privacy and trust through blinded information exchange and corroboration, using secrets unavailable to the coordinating network element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If identity information is hidden using prior art methods, then privacy protection is improved, but trust in the veracity of the information source deteriorates
Solution Approach 1:
The patent introduces a coordinating network element that acts as an intermediary to manage blinded information exchange. This intermediary facilitates data-based activities between parties while preventing substantive access to identity information, yet maintains trust through protocol-enforced corroboration mechanisms that verify information source authenticity without exposing identities.
Solution Approach 2:
The patent segments identity information from data information by using tokenization and blinding techniques. Identity information is represented as opaque tokens that cannot be substantively accessed or correlated, while data-based activities proceed using these segmented representations, thereby protecting privacy while maintaining verifiable trust through the protocol structure.
2Object-affected harmful factors
If tokenization and encryption are used to prevent substantive access to data information, then privacy protection is improved, but system complexity increases
Solution Approach 1:
The coordinating network element serves as a specialized intermediary that manages the complexity of tokenization and encryption operations. By centralizing protocol management in this intermediary, the system achieves strong privacy protection through blinded information exchange while containing complexity within a dedicated component rather than distributing it throughout the entire system.
Solution Approach 2:
The patent uses tokenization to create opaque representations (copies) of identity information that can be used in data-based activities without exposing the original sensitive data. These token copies enable privacy-protecting operations while maintaining the functional capabilities needed for verification and corroboration, thereby managing complexity through substitution rather than direct manipulation of sensitive information.
Data Source
AI summary
A third-party intermediary manages a protocol that prohibits the third-party intermediary from substantively accessing data content that, at least in part, underlies received protocol-compliant requests. By one approach, these teachings provide for preventing substantive access to data information that is included within the protocol-compliant request as one or more functions of data, parts of which data may be in tokenized or untokenized form, wherein the values of the functions are generated using secrets, at least one of which is unavailable to the third-party intermediary. By one approach, tokens comprised of data in tokenized form are generated using secrets, at least one of which is unavailable to the third-party intermediary.
