Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing instant communication technologies lack robust encryption methods, allowing unauthorized access to confidential documents and personal information during file transfers over the Internet, posing a significant security risk.

Innovation Solution

A method and device for encrypting and decrypting data using eyeball information as a key, where user information is acquired, a key acquisition instruction is sent to a terminal to obtain eyeball information, and the data is encrypted and decrypted using this key, ensuring secure transmission and access only upon successful decryption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional file transfer methods are used without encryption, then ease of operation is improved, but security is worsened

Engineering Contradiction:

Improvefile transfer convenienceVSAvoiddata security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by capturing the user's eyeball information in advance before file transfer and using it to generate encryption keys. The eyeball information is captured when the user looks at the screen, and this pre-captured biometric data is then used to encrypt files before transmission, ensuring security without affecting the convenience of file sharing.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If encryption is applied to file transfers, then data security is improved, but device complexity is worsened

Engineering Contradiction:

Improvedata securityVSAvoidencryption system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by using the user's own eyeball information to generate both encryption and decryption keys. The system automatically captures eyeball data, processes it through algorithms to generate keys, and uses these keys for encryption and decryption operations. This self-contained approach simplifies the overall system architecture while maintaining high security standards.

Inventive Principle:

Principle #25Self-service

3Reliability

If eyeball information is used as encryption key, then security is improved, but ease of operation is worsened

Engineering Contradiction:

Improveencryption securityVSAvoiddecryption convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical authentication methods (passwords, physical keys) with a biological system - the user's eyeball information. Instead of requiring users to remember complex passwords or carry physical encryption keys, the system uses the unique physiological characteristics of the user's eyes to generate cryptographic keys, making the authentication process more natural and convenient.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An encryption method for data includes acquiring data to be encrypted and user information set relevant to the encryption, sending a key acquisition instruction to a terminal corresponding to the user information, receiving a key returned from the terminal corresponding to the user information, encrypting the data to be encrypted by using the key, and transmitting encrypted data to the terminal corresponding to the user information. The present disclosure can ensure the security of files transmitted over a network, which is convenient and fast and significantly improves the user experience.
