Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an efficient way to control access and transfer of digital resources within a network to prevent misuse.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access controls and transfer restrictions are implemented on digital resources, then security and misuse prevention are improved, but system complexity increases
Solution Approach 1:
The patent combines multiple access control functions (authentication, authorization, time restrictions, transfer controls) into a single integrated smart contract system. The smart contract merges cryptographic validation, access policy enforcement, and transfer restrictions into one unified mechanism, reducing the need for separate security systems while maintaining comprehensive protection.
Solution Approach 2:
The smart contract implements self-service access control by automatically validating authentication credentials, checking access policies, and enforcing transfer restrictions without requiring manual intervention. The system autonomously evaluates requests against stored policies and executes appropriate actions, reducing operational complexity while enhancing security.
2Reliability
If authentication credentials and access validation are performed for each request, then access control reliability is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-storing access control policies, authentication credentials, and validation rules in the smart contract before actual access requests occur. This pre-preparation allows rapid retrieval and evaluation during request processing, reducing processing time while maintaining thorough validation.
Solution Approach 2:
The smart contract implements feedback mechanisms that cache authentication results and access validation outcomes. When similar requests are made, the system can quickly reference previous validation results, reducing redundant processing time while ensuring consistent and reliable access control decisions.

AI summary
A system is provided for implementing time-restricted access control to electronic digital resources. In some embodiments, the custom set of executable code used to generate the digital resource may provide granular control over access restrictions for accessing, viewing, and/or transferring the digital resource. Such access restrictions may include time duration restrictions, access frequency restrictions, data quality restrictions, and/or the like. In this way, the system may limit access to the digital resource in a secure manner.
