Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current secured storage devices with DRM protection mechanisms prevent authorized users from transferring protected digital content from one SSD to another, forcing users to maintain multiple SSDs for new content while keeping old content, which is inconvenient and inefficient.

Innovation Solution

A system and method that employs a third party to establish a virtual secure channel between source and destination SSDs, allowing the third party to read and write protected digital data while ensuring eligibility and security, thereby enabling the transfer of multimedia content with associated DRM rights and authentication details.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If DRM protection mechanisms are implemented in secured storage devices, then digital content security is improved, but authorized users cannot transfer protected content from one SSD to another

Engineering Contradiction:

Improvedigital content securityVSAvoidcontent transfer capability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a third party as an intermediary that facilitates the transfer of protected digital content between SSDs. The third party establishes secure communication channels with both the source and destination SSDs, enabling authorized users to transfer content while maintaining DRM protection. This mediator approach resolves the contradiction by allowing transfers through a trusted intermediate entity that verifies eligibility and manages the transfer process securely.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If users purchase new SSDs for additional storage, then storage capacity is improved, but users must maintain multiple SSDs to preserve old content

Engineering Contradiction:

Improvestorage capacityVSAvoidnumber of SSDs to manage

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent enables users to copy protected digital content from one SSD to another through the third party intermediary. Instead of being forced to maintain multiple SSDs simultaneously, users can create authorized copies of their content on new SSDs while the original content remains protected on the source device. This copying mechanism allows users to consolidate their storage into a single SSD while preserving access to all content.

Inventive Principle:

Principle #26Copying

3Reliability

If strict DRM policies are enforced on SSDs, then content protection is improved, but authorized transfers between SSDs are blocked

Engineering Contradiction:

Improvecontent protectionVSAvoidauthorized transfer flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The third party acts as a trusted mediator that understands and enforces DRM policies while facilitating authorized transfers. The intermediary verifies the eligibility of both source and destination SSDs, ensures proper authentication, and manages the transfer process in compliance with DRM rules. This approach maintains strict content protection while enabling flexible authorized transfers that would otherwise be blocked by rigid DRM enforcement.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A third party is configured to establish a virtual secure channel between a source SSD and a destination SSD via which the third party reads protected digital data from the source SSD and writes the protected digital data into the destination SSD after determining that each party satisfies eligibility prerequisites. An SSD is configured to operate as a source SSD, from which protected data can be copied to a destination SSD, and also as a destination SSD, to which protected data of a source SSD can be copied.
