Digital Credential System with Location and Time Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital content distribution systems focus primarily on initial access security, failing to monitor and enforce usage restrictions once access is granted, leading to potential misuse, copying, and sharing of restricted content.
Innovation Solution
Implementing a digital content delivery system that monitors usage signals and enforces access and usage restrictions by suspending or terminating access when misuse is detected, utilizing digital credentials with location and time-based restrictions, and embedding digital watermarks to track unauthorized copies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If initial user authentication is required before providing access to digital content, then access security is improved, but usage monitoring and enforcement capability deteriorates
Solution Approach 1:
The system performs preliminary actions by embedding usage restrictions and monitoring mechanisms into digital credentials before they are presented to users. The credential itself contains embedded logic that automatically enforces usage rules without requiring continuous system intervention, thus improving both security and monitoring capability simultaneously.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring usage signals from digital content and comparing them against predefined restrictions. When violations are detected, the system provides feedback by suspending or terminating access, creating a closed-loop control system that actively enforces usage policies rather than passively relying on initial authentication.
2Ease of operation
If digital content is made accessible to users, then ease of operation is improved, but risk of unauthorized use increases
Solution Approach 1:
The system applies dynamics by making access rights dynamic rather than static. Digital credentials contain time-based and location-based restrictions that automatically adjust access permissions based on current conditions. This allows content to be easily accessible when conditions are met while automatically restricting access when conditions are violated, thus maintaining ease of operation while reducing unauthorized use risk.
Solution Approach 2:
The system introduces digital credentials as an intermediary between the content delivery system and end users. These credentials act as smart contracts that encode usage restrictions and automatically enforce them, mediating between the need for easy content access and the need to prevent unauthorized use without requiring complex continuous authentication.
3Reliability
If digital credentials with location and time restrictions are implemented, then usage control is improved, but system complexity increases
Solution Approach 1:
The system applies segmentation by dividing usage control into discrete, modular components within digital credentials. Each credential contains specific time-based and location-based restriction modules that can be independently configured and enforced. This modular approach improves usage control while managing system complexity through standardized, reusable credential templates.

AI summary
A method for issuing digital credentials includes assigning a digital credential to a user account maintained by the digital content delivery system; receiving, from a mobile computing device associated with the user account, a first request for the digital credential; in response to receiving the first request: determining whether a current location of the mobile computing device is within a predetermined geographic distance of the selected exhibitor location, and determining whether a remaining amount of time until a scheduled start time of the selected scheduled presentation is less than a threshold amount of time; and in response to determining that either the current location of the mobile computing device is outside of the predetermined geographic distance of the selected exhibitor location or the remaining amount of time until the scheduled start time of the selected scheduled presentation is greater than the threshold amount of time, denying the first request.
