Transactional Artifact Access Control Against Compromised Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital content access control systems are vulnerable to unauthorized access due to compromised security tokens, leading to unauthorized users gaining access to digital content, despite transactional relationships.
Innovation Solution
Implementing a fraud detection system that utilizes transactional history artifacts and derived artifacts to authenticate users, where transaction history data modifies credentials and verifiers, ensuring only authorized users can access digital content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service providers implement digital rights management techniques with security tokens to control access to digital content, then access control capability is improved, but system vulnerability to unauthorized access increases when tokens are compromised
Solution Approach 1:
The patent implements dynamic credential verification by continuously updating transactional artifacts (credentials and verifiers) based on transaction history. Instead of static security tokens, the system generates new credentials for each transaction attempt, making compromised tokens useless for future unauthorized access attempts. This dynamic approach resolves the contradiction by maintaining strong access control while eliminating the vulnerability of static token compromise.
Solution Approach 2:
The system incorporates feedback mechanisms by using transaction history to modify and update credentials and verifiers. Each successful or attempted transaction feeds information back into the system, which then updates the transactional artifacts. This feedback loop ensures that access control decisions are based on current, validated transaction patterns rather than static tokens, preventing unauthorized access while maintaining reliable control.
2Reliability
If service providers require users to enter into transactional relationships with compensation requirements, then digital content protection is improved, but user access convenience deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-establishing transactional relationships and storing transaction history artifacts before actual content access is needed. Credentials and verifiers are generated and validated in advance based on compensation requirements and user authorization. When users need to access content, the verification process uses these pre-computed artifacts, eliminating the need for repeated compensation transactions and improving convenience while maintaining protection.
Solution Approach 2:
The system implements self-service by enabling automated credential verification using stored transactional artifacts. Once the initial transactional relationship is established with compensation, the system automatically generates and validates credentials for subsequent access requests without requiring manual intervention or repeated payment processes. This self-service mechanism maintains strong protection while significantly improving user access convenience.

AI summary
Methods and systems are provided for use with digital data processing systems to control or otherwise limit access to networked resources based, at least in part, on transactional artifacts and/or derived artifacts. The transactional artifacts and/or derived artifacts are processed based on transactional relationships between devices within the digital data processing systems.
