Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current digital rights management systems for streaming content and services lack effective protection against unauthorized use and distribution due to the open nature of the Internet, failing to securely deliver and manage digital rights for global content delivery.

Innovation Solution

A digital rights management system that uses secure protocols like SSL/TLS to establish a private relationship between client devices and servers, validates certificates, and encrypts resource identifiers with dynamic encryption keys and hash values, hiding them from unauthorized access and controlling access entitlements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the Internet is used as an open network for global content delivery, then the opportunity to deliver content to a worldwide customer base is improved, but the ability to protect content from unauthorized use and distribution deteriorates

Engineering Contradiction:

Improveglobal content delivery capabilityVSAvoidunauthorized use and distribution

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system segments content access by creating distinct secure communication channels between clients and servers. Each client device establishes individual encrypted connections, dividing the open network into protected segments that prevent unauthorized access while maintaining global reach

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces certificate-based authentication as an intermediary mechanism between clients and servers. This intermediary validates identities and establishes trusted relationships, enabling secure content delivery across the open Internet without exposing content to unauthorized distribution

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If certificate validation and secure protocols are implemented, then content protection from unauthorized access is improved, but the complexity of the digital rights management system increases

Engineering Contradiction:

Improveunauthorized access protectionVSAvoiddigital rights management system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent implements universal certificate-based authentication that works across multiple platforms and devices. The same SSL/TLS protocol and certificate validation mechanism serves all client devices, reducing overall system complexity despite enhanced security requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses self-service mechanisms where client devices automatically perform certificate validation and establish secure connections without manual intervention. This automation reduces operational complexity while maintaining strong security protections

Inventive Principle:

Principle #25Self-service

AI summary

Managing digital rights of contents and services streamed to a client device, including: receiving and validating a certificate from the client device; enabling the client device to log into and communicate with a server using a secure protocol to establish a private relationship between the client device and the server; and transmitting a resource identifier to the client device using the secure protocol when the private relationship is established.
