Mobile Content Distribution Using Embedded License Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in efficiently distributing electronic content to multiple mobile stations in a network environment due to copyright protection measures and the complexity of content distribution, leading to delayed adoption of new content and increased inconvenience for users.
Innovation Solution
The implementation of distribution management data (DMD) is added to electronic content, allowing one mobile station to store and duplicate licensed content for distribution to others, with each station determining operational permissions before use, ensuring copyright protection and simplifying the distribution process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic content is distributed through a central server system to multiple mobile stations, then copyright protection is maintained, but distribution efficiency is reduced and user convenience deteriorates
Solution Approach 1:
The patent segments the content distribution system into multiple independent mobile stations that can each store and distribute content locally. Instead of relying on a single central server, the system divides the distribution function across multiple nodes (mobile stations), allowing parallel distribution to multiple users simultaneously while maintaining copyright protection through embedded management data in each copy.
Solution Approach 2:
The patent introduces distribution management data as an intermediary mechanism embedded within the electronic content itself. This data structure acts as a mediator that carries copyright information and licensing terms, enabling automated copyright protection without requiring constant server intervention. The management data includes content identification, licensing information, and distribution control parameters.
2Reliability
If electronic content is distributed through a central server system, then copyright management is maintained, but the time required for content adoption increases
Solution Approach 1:
The patent implements preliminary action by embedding distribution management data directly into the electronic content during the initial distribution from the server. This pre-configured management data enables subsequent peer-to-peer distributions to occur automatically without requiring real-time server authorization. Mobile stations receive pre-authorized content that they can immediately share with others, dramatically reducing adoption time while maintaining copyright control through the embedded licensing information.
3Reliability
If electronic content is distributed through a central server system, then content licensing is controlled, but system complexity increases
Solution Approach 1:
The patent extracts the copyright management functionality from the central server and embeds it directly into the electronic content itself through distribution management data. This extraction eliminates the need for complex server-based authorization systems and inter-station communication protocols for licensing verification. Each mobile station independently validates and enforces licensing terms using the embedded management data, significantly simplifying the overall system architecture.

AI summary
Disclosed is a method and a system for efficiently distributing electronic content such as game software to a plurality of users in a mobile communication network or a system including a plurality of mobile stations, In order to distribute an electronic content to a plurality of mobile stations after one mobile station receives and stores the electronic content having a license or a copyright from a server or a system having content, the mobile station distributes duplicates of the electronic data to other mobile stations, In addition, when the distributed content is executed, each mobile station determines whether or not operational grant is permitted so as to use the electronic content, Furthermore, when the distributed electronic content is executed in each mobile station, the mobile station uses electronic content after determining whether or not a mobile station distributing the content permits operational grant.
