Solution Overview

Problem

Existing medical information systems face challenges in protecting patient personal information, as digital patient data is vulnerable to duplication and leakage, exposing sensitive information during transmission and storage.

Innovation Solution

A cloud-based medical image database method that separates medical and patient information data, encrypts patient information using blockchain techniques for secure transmission and storage, and decrypts it for secure diagnosis and consulting using big data processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If patient information data is transmitted and stored in medical information systems, then medical services can be provided efficiently, but personal information leakage and duplication risks increase

Engineering Contradiction:

Improvemedical service efficiencyVSAvoidpersonal information leakage risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent segments patient information into two distinct parts: personal identification information (PII) and non-personal identification information (non-PII). PII is encrypted and stored separately in a first database, while non-PII is stored in a second database. This segmentation allows medical services to access necessary information efficiently while protecting sensitive personal data from exposure during transmission and storage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mechanism - a unique patient identifier or code - that enables access to medical information without directly exposing personal identification information. This intermediary acts as a bridge between the need for efficient medical service delivery and the requirement for personal information protection, allowing authorized access while maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If patient personal information is separated and managed separately, then information security is improved, but system complexity increases

Engineering Contradiction:

Improveinformation securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the medical information system into distinct segments: a first database for encrypted PII, a second database for non-PII, and separate processing pathways for handling different types of information. This segmentation improves security by isolating sensitive data while managing complexity through clear separation of concerns and defined access protocols for each segment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies encryption transformations to personal identification information, changing its parameter state from plaintext to encrypted format. This parameter change enables secure storage and transmission while maintaining the ability to retrieve and use the information when needed, balancing security requirements with system usability without excessive complexity.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If blockchain encryption technique is used to encrypt patient information data, then data security and irreversibility are guaranteed, but processing time and computational resources increase

Engineering Contradiction:

Improvedata securityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies blockchain encryption selectively only to personal identification information that requires highest security protection, rather than encrypting all medical data. This partial application of encryption maintains strong security for sensitive PII while avoiding the computational overhead of encrypting entire datasets, thus reducing processing time and resource consumption for non-sensitive information.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent performs encryption of personal identification information in advance during data entry or initial storage, before the data needs to be accessed or processed. This preliminary encryption action ensures security is established upfront, allowing faster retrieval and processing of already-encrypted data without incurring decryption overhead during critical access operations.

Inventive Principle:

Principle #10Preliminary action
