Attribute Management System for Online Transaction Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face issues with providing unnecessary personal information during online transactions, as receiving entities often request excessive data, and there is a lack of assurance that provided attributes are accurate, leading to potential mishandling of private information and repetitive data entry across different entities.
Innovation Solution
An attribute management system where a user's attributes are verified and stored by an attributes server, which determines the necessary attributes required for a specific online transaction based on a policy associated with the receiving entity, ensuring only required information is shared and maintaining accuracy through authentication and verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a receiving entity requests multiple user attributes to complete an online transaction, then the entity can process the transaction, but the user's private information may be mishandled and unnecessary data is collected
Solution Approach 1:
The patent extracts only the necessary attributes required for transaction processing from the complete set of user attributes, separating essential data from unnecessary information. The attribute management system identifies and provides only the minimum required attributes to the receiving entity, eliminating exposure of irrelevant private information.
Solution Approach 2:
The patent introduces an attribute management system as an intermediary between the user and the receiving entity. This mediator verifies user attributes, determines which attributes are necessary for the transaction based on policy, and selectively provides only those required attributes to the receiving entity, thereby protecting user privacy while enabling transaction processing.
2Reliability
If a user provides attributes for each new online transaction with a new receiving entity, then the transaction can be completed, but the user experiences repetitive data entry burden
Solution Approach 1:
The patent performs preliminary verification and storage of user attributes in the attribute management system before actual transactions occur. User attributes are verified once and stored securely, so that during subsequent transactions, the system can quickly retrieve and provide the necessary attributes without requiring users to re-enter data each time.
Solution Approach 2:
The patent creates a universal attribute management system that serves multiple receiving entities and multiple transactions. The verified user attributes stored in the system can be reused across different transactions with different receiving entities, eliminating the need for repetitive data entry while maintaining transaction completion capability.
3Reliability
If a receiving entity requests user attributes, then the entity can process the transaction, but the entity is often unable to ensure that attributes provided by a user are accurate
Solution Approach 1:
The patent implements a feedback mechanism where user attributes are verified against trusted sources or previous verification results before being provided to the receiving entity. The attribute management system checks the accuracy and validity of attributes, ensuring that only verified and accurate information is transmitted, thereby resolving the issue of unreliable attribute data.
Data Source
AI summary
A first server device receives a request for attributes, of a user, from a second server device associated with a receiving entity. The first server device determines whether the receiving entity is entitled to receive the attributes, and authenticates an identity of the user. The first server device also identifies the attributes based on the identity when the receiving entity is entitled to receive the attributes, and transmits the identified attributes to the second server device.
