Solution Overview

Problem

Data processing devices, such as portable storage devices, face challenges in balancing data security and user convenience, particularly when backing up data from memory cards, as existing security measures often require authentication input, slowing startup times and complicating quick data transfer.

Innovation Solution

A data processing device with a data storage section, authentication information storage, and an input section that allows reading of data only when authentication information matches, while permitting writing to an external storage device without authentication when inserted, and allowing registration of external devices for secure data access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication information input is required at startup to ensure data security, then data security is improved, but startup speed decreases and user convenience deteriorates

Engineering Contradiction:

Improvedata securityVSAvoidstartup speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent segments the authentication process into two distinct modes: a full authentication mode for reading data from the data storage section, and a simplified authentication mode for writing data from external storage devices. This segmentation allows the system to maintain security for sensitive operations while enabling quick data transfer for backup operations without requiring full authentication, thus resolving the contradiction between security and startup speed.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies different authentication requirements to different functional sections of the storage device. The data storage section (internal storage) requires full authentication for reading to ensure security, while the external storage device interface allows writing without authentication. This local differentiation of security measures allows the system to protect critical data while maintaining user convenience for backup operations.

Inventive Principle:

Principle #3Local quality

2Reliability

If authentication information input is required for reading data, then data security is improved, but ease of operation deteriorates during backup operations

Engineering Contradiction:

Improvedata securityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent divides authentication operations into segmented pathways: one requiring authentication information for reading from the data storage section, and another allowing direct writing from external storage devices without authentication. This segmentation enables users to perform backup operations easily while maintaining security controls for data access, resolving the contradiction between security and ease of operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system enables self-service backup operations where users can directly write data from external storage devices to the data storage section without requiring authentication input. The authentication mechanism automatically manages security for reading operations while allowing unrestricted writing operations, making the backup process as convenient as direct file transfer.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If no data security measure is taken, then ease of operation is improved, but data security deteriorates as data may be read by third parties

Engineering Contradiction:

Improveease of operationVSAvoidunauthorized data access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements local quality control by applying authentication requirements specifically to the reading operation of the data storage section while leaving writing operations from external devices unrestricted. This targeted security measure protects against unauthorized data access by third parties while maintaining ease of operation for legitimate backup operations, resolving the contradiction between security and usability.

Inventive Principle:

Principle #3Local quality

AI summary

A data processing device includes a data storage section that stores data; an authentication information storage section that stores first authentication information registered by a user; an input section that allows the user to input second authentication information; a first judgment section that permits reading of the data stored in the data storage section when the first authentication information matches the second authentication information, and does not permit reading of the data stored in the data storage section when the first authentication information does not match the second authentication information; a slot into which an external storage device can be inserted; and a writing admission section that permits writing of the data stored in an external storage device into the data storage section without input of the second authentication information when the external storage device is inserted into the slot.
