Solution Overview

Problem

Conventional cryptography methods rely on text-based methods for generating and communicating encryption keys, which are cumbersome and inconvenient, requiring physical interaction with a keyboard.

Innovation Solution

A gesture-based system that uses sensor information, such as image and depth information, to recognize public and private gestures, allowing for the generation and distribution of encryption keys, and authorizes access to resources based on these gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If text-based methods are used to generate and communicate encryption keys, then security can be maintained, but user convenience and ease of operation deteriorate due to requiring physical keyboard interaction

Engineering Contradiction:
Improveuser convenienceVSAvoidinteraction complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical keyboard input system with a gesture-based recognition system using sensors (e.g., camera, depth sensor) to detect and interpret user gestures in 3D space. This substitution eliminates the need for physical keyboard interaction while maintaining security through gesture verification, directly resolving the contradiction between ease of operation and security requirements

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces gesture recognition technology as an intermediary between the user and the encryption key generation system. Instead of direct keyboard input or complex authentication, users perform gestures that are captured by sensors and translated into cryptographic operations, simplifying the user experience while preserving security through the gesture-key association

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If conventional text entry methods are used for key communication, then security can be ensured, but productivity and efficiency deteriorate due to the burdensome process

Engineering Contradiction:
Improvekey generation efficiencyVSAvoidtime for key communication
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces time-consuming text entry and key communication processes with instantaneous gesture recognition and verification. The gesture-based system allows users to generate and exchange encryption keys through simple physical movements that are immediately captured and processed by the sensor system, dramatically improving productivity and eliminating time losses associated with traditional text-based key management

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent enables preliminary gesture-based key generation to occur before actual secure communication is needed. Users can pre-generate and store encryption keys associated with specific gestures, so that when secure communication is required, the keys are already prepared and ready for immediate use, reducing time loss and improving overall productivity

Inventive Principle:
Principle #10Preliminary action

AI summary

A secure communication method including obtaining sensor information of at least one user, the sensor information comprising one or more of image information and depth information; recognizing at least one gesture in accordance with the sensor information of the at least one user; determining whether each of the recognized at least one gesture is a public gesture or a private gesture in accordance with a zone where the gesture was performed, the zone being selected from a plurality of zones; and authorizing access to a resource when it is determined that the at least one gesture is determined to be the public gesture or the private gesture.
