Pseudonymous Reputation via Chained Endorsers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems find it difficult to track and enforce negative reputation for service accounts, as users can easily create new accounts to avoid accountability.
Innovation Solution
A pseudonymous reputation system using a chain of endorsers, where each user registers with a unique identifier that maintains their history across service providers without revealing personal information, allowing recognition of repeat users while preserving privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users register new accounts to avoid negative reputation, then user privacy is protected, but reputation tracking reliability deteriorates
Solution Approach 1:
The patent introduces pseudonymous identifiers as intermediaries between users and service providers. These identifiers enable reputation tracking without exposing personal information, as they serve as mediators that link user actions to reputation records without revealing identity. The pseudonymous identifiers are generated through cryptographic processes involving endorsers, creating a bridge that maintains both privacy and accountability.
Solution Approach 2:
The patent creates copies of user identity in the form of pseudonymous identifiers that can be used for reputation tracking. Instead of using real personal information, the system generates pseudonymous copies that fulfill the function of identifying users for reputation purposes while preserving their actual privacy. These pseudonymous copies can be transferred and verified across different service providers.
2Loss of information
If pseudonymous identifiers are used for registration, then user privacy is preserved, but account creation complexity increases
Solution Approach 1:
The patent segments the account creation process into distinct phases: first, users obtain pseudonymous identifiers through endorsers without immediate service provider involvement; second, these identifiers are used for service registration. This segmentation allows privacy protection to be handled separately from service-specific registration, reducing the perceived complexity at any single point in the process.
Solution Approach 2:
The patent performs preliminary action by having users obtain pseudonymous identifiers and endorsements before actual service registration. This preliminary setup phase separates the complex cryptographic operations from the service-specific registration, so users deal with privacy-preserving mechanisms once before encountering service providers, rather than facing complexity at each registration point.
Data Source
AI summary
Techniques are disclosed to provide enforceable pseudonymous reputation through chained endorsers. In various embodiments, a request associated with a chained endorsement operation is received via a communication interface. A client identity information is extracted from the request. Data comprising or associated with the client identity information is combined with a secret value. A one-way transform of the combined value is performed. A result of the one-way transform is returned to a client with which the chained endorsement operation is associated.
