Digital Content Access Control via Device Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital content dissemination systems lack effective control over access to digital files, which can lead to unauthorized consumption and compromise the integrity of the content.
Innovation Solution
A system that utilizes a content-access application to register devices with a publisher, allowing for secure acquisition and controlled access to digital content through unique identifiers and encryption protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access controls are applied to digital files, then content integrity and security are improved, but ease of access and dissemination are worsened
Solution Approach 1:
The patent segments access control into multiple hierarchical levels: file-level encryption, section-level permissions, and user-role-based access. This allows different portions of digital content to have different access requirements, maintaining security for sensitive sections while allowing free access to public sections, thus resolving the contradiction between security and ease of access.
Solution Approach 2:
The patent introduces an intermediary access control system that acts as a mediator between users and digital content. This intermediary layer implements encryption protocols and permission verification without preventing legitimate access, thereby maintaining content integrity while preserving ease of access for authorized users.
2Reliability
If all aspects of access are controlled, then content security is improved, but flexibility in content presentation is worsened
Solution Approach 1:
The patent implements dynamic access control where permissions and presentation formats can change based on user credentials, device type, and context. The system adapts security measures and content presentation dynamically rather than applying static restrictions, thereby maintaining security while preserving flexibility in how content is presented to different users.
Solution Approach 2:
The patent applies different security and presentation rules to different sections of digital content based on their sensitivity and intended use. Public sections allow flexible presentation and access, while sensitive sections have stricter controls. This localized approach to access control maintains overall security while preserving flexibility where appropriate.
3Reliability
If access control systems are implemented, then unauthorized consumption is prevented, but device complexity is worsened
Solution Approach 1:
The patent implements self-service authentication mechanisms where users automatically present credentials and the system automatically verifies permissions without requiring manual intervention from administrators. Encryption and decryption operations are performed automatically by the system, reducing the operational complexity despite the sophisticated security measures in place.
Data Source
AI summary
A content-access application and a registration code are provided to a user. The content-access application is opened and used to select a device. An identifier permanently associated with the device is determined and stored. The user provides the registration code and the identifier to the publisher. The publisher associates the registration code with the identifier to form a registration unit. To acquire content, the user requests a content file from and provides the registration code to the publisher, which associates the registration unit with the requested content file to form a unique user content file. The identifier of the registered device is compared with the associated identifier of the unique user content file. Access to the unique user content file is granted by the content-access application only on correspondence of the identifier associated with the unique user content file and the unique identifier stored by the registered device.
