Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing technologies do not provide adequate data security for portable data storage devices, allowing users to easily share downloaded digital data, thereby infringing on copyright and intellectual property rights.

Innovation Solution

A secure data transfer method is implemented where a unique first PSID parameter is associated with each portable data storage device, and a matching second PSID parameter is embedded in a rights object within a data file, ensuring that data can only be accessed if the PSID parameters match, thereby preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If data is made easily accessible and transferable to portable devices, then user convenience and ease of operation improve, but data security and intellectual property protection deteriorate

Engineering Contradiction:

Improveease of data transferVSAvoiddata security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The data file is segmented into multiple components: the actual data content, a rights object containing access control information, and a PSID parameter for device identification. This segmentation allows the data to be easily transferred while embedding security controls that restrict access to authorized devices only.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A rights object acts as an intermediary between the data and the portable data storage device. This rights object contains the second PSID parameter and control logic that mediates access requests, comparing the device's first PSID parameter against the embedded second PSID parameter to determine whether to grant access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If data can be freely copied and shared across multiple devices, then adaptability and versatility improve, but copyright protection and intellectual property rights worsen

Engineering Contradiction:

Improvedata portabilityVSAvoidunauthorized sharing

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The security mechanism applies local quality by binding the data access rights to a specific device's PSID parameter. The rights object embedded in the data file contains a second PSID parameter that must match the first PSID parameter of the specific portable data storage device, creating device-specific access control that allows portability while preventing unauthorized sharing.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system performs preliminary action by embedding the rights object with the second PSID parameter into the data file before transfer. This pre-configured access control mechanism is established in advance, so that when the data is transferred to a portable device, the security constraints are already in place and automatically enforced without requiring additional authentication steps.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If complex security measures are implemented to prevent unauthorized access, then data security improves, but device complexity and ease of operation worsen

Engineering Contradiction:

Improvedata securityVSAvoidsecurity mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The security mechanism implements self-service by embedding the control logic and PSID parameter comparison functionality directly into the portable data storage device. The device automatically performs the security check by comparing its first PSID parameter with the second PSID parameter in the rights object, without requiring external authentication servers or complex user verification processes.

Inventive Principle:

Principle #25Self-service

4Object-generated harmful factors

If PSID parameter matching is required for data access, then intellectual property protection improves, but ease of operation and user convenience worsen

Engineering Contradiction:

Improvecopyright protectionVSAvoiddata access convenience

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The PSID parameter matching mechanism operates transparently through self-service automation. The control logic embedded in the portable data storage device automatically compares the first PSID parameter (stored in the device) with the second PSID parameter (embedded in the rights object) without requiring user intervention. This automated process provides strong copyright protection while maintaining ease of operation for authorized users.

Inventive Principle:

Principle #25Self-service

AI summary

Techniques for transferring secured data from a vending device to a portable data storage device are described herein. The vending device receives a request from a user of the portable data storage device for digital contents to be stored on the portable data storage device and requests for a payment for the requested digital contents to be paid by the user. The vending device locates a first portable storage identification (PSID) parameter unique to the portable data storage device, and then generates a rights object including a second PSID parameter that is equal to the first PSID parameter to prevent the digital contents from being accessed at a data storage medium other than the portable data storage device. It is to be appreciated some or all of the above processing can be completed by a back-end device separate from the vending device.
