Personal Digital Library Manager for Cross-Device Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital object distribution systems are often proprietary and vertically integrated, limiting user flexibility and security, as they require specific equipment and file formats, making it difficult for users to access digital content across different devices and platforms, and are vulnerable to piracy due to cumbersome DRM-based security measures.
Innovation Solution
A method and system that uses personal reading right data as the basis for management, distribution, security, and invoicing, allowing users to access digital objects across multiple devices by storing identification data locally and generating personal reading rights, which are managed by a cloud-based library, enabling seamless access and use of digital content without the need for direct storage on the user's device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM-based security measures are used to protect digital objects, then security against piracy is improved, but user flexibility and ease of access across different devices deteriorates
Solution Approach 1:
The system segments the digital object protection mechanism by separating the encrypted digital object from the decryption key. The digital object is encrypted with a key that is segmented and stored across multiple trusted authorities, requiring collaboration between multiple parties to access the content. This segmentation allows secure distribution while enabling flexible access through authorized combinations of key fragments.
Solution Approach 2:
The patent introduces trusted authorities as intermediaries between the content distributor and the user's device. These authorities hold fragments of the decryption key and act as mediators that verify device trustworthiness before releasing key fragments. This intermediary layer enables both security (through verified trust) and flexibility (through authorized access on multiple devices).
2Device complexity
If proprietary distribution systems with specific file formats are used, then control over digital content from creation to distribution is improved, but interoperability between different equipment and platforms deteriorates
Solution Approach 1:
The system implements universality by enabling a single encrypted digital object to be accessed on multiple different types of devices through the use of trusted authorities. The decryption mechanism is designed to work across different platforms and equipment types, allowing the same protected content to be universally accessed wherever trusted authorities are present, thus achieving multi-functionality without sacrificing security.
3Reliability
If DRM files with access keys are provided only upon proof of purchase, then digital rights management is improved, but ease of operation for users deteriorates
Solution Approach 1:
The system performs preliminary action by pre-distributing fragments of the decryption key to multiple trusted authorities before the actual content access is needed. When a user makes a legitimate purchase, the authorities that already hold key fragments can quickly verify the purchase and provide access without requiring complex real-time key generation or distribution. This preliminary distribution of key fragments significantly simplifies the access process while maintaining security.

AI summary
The present invention relates to a method for providing at least one digital object (01, 02, 03) to a user (U) having a first digital reading device (T1) on which identification data (ID), containing at least one piece of identification information related to the user (U), is locally stored, said method comprising: a step of generating, by means of a management server (20), the rights to read personal read rights data (DLP01, DLP02, DLP03); a step of sending the personal read rights data (DLP01, DLP02, DLP03) to a personal digital library manager (30); and a step (S30) of authenticating the user by means of identification data (ID). The present invention also relates to the corresponding providing system (10).
