Solution Overview

Problem

Remote document execution faces challenges such as security risks due to network information transfer, network bottlenecks, inadequate identity verification, and limitations in executing documents across different geographical locations in real-time.

Innovation Solution

An augmented reality system using head-mounted displays and biometric verification engines to create transfer tokens for secure and efficient remote document execution, allowing identity confirmation and digital signatures across networks without prior knowledge of network services, and enabling real-time or delayed authentication and document execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If information is transmitted across a network for remote document execution, then document execution is enabled remotely, but security risks and network bottlenecks increase

Engineering Contradiction:

Improveremote document executionVSAvoidnetwork security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent extracts the essential authentication and execution data from the complete document information, creating compact transfer tokens that contain only the necessary biometric verification and gesture authentication data. This extraction eliminates the need to transmit large amounts of document data across the network, thereby reducing security risks and network bottlenecks while maintaining remote document execution capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system segments the document execution process into distinct phases: local biometric verification, gesture capture, token generation, and token transmission. By dividing the process into segments, the patent enables secure local processing of sensitive data and minimal network transmission of only essential authentication tokens, resolving the contradiction between remote execution and network security

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If complete document information is transmitted across the network, then remote document execution is enabled, but network bandwidth is consumed and bottlenecks occur

Engineering Contradiction:

Improveremote document executionVSAvoiddata transmission volume

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential authentication elements (biometric data and gesture information) from the complete document package, creating minimal transfer tokens. This extraction principle reduces data transmission volume from megabytes of document data to kilobytes of authentication tokens, eliminating network bottlenecks while preserving remote execution functionality

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs preliminary local processing of document data, biometric verification, and gesture capture before transmission. By completing these actions locally in advance, the patent eliminates the need to transmit large volumes of processed data across the network, thereby reducing data transmission volume while enabling remote document execution

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If traditional network transfer methods are used, then document execution is enabled, but security risks from data transmission increase

Engineering Contradiction:

Improvedocument executionVSAvoidsecurity risks

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and transmits only minimal authentication tokens containing biometric verification results and gesture data, rather than transmitting complete document information. This extraction approach minimizes the attack surface for security risks while maintaining document execution capability, as the transmitted tokens cannot be used to reconstruct the original document

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system introduces transfer tokens as an intermediary between the local device and remote server. These tokens mediate the authentication process by carrying essential verification data without exposing sensitive document information or biometric data, thereby reducing security risks associated with direct data transmission

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An augmented reality user device includes a display, a physical identification verification engine, a gesture confirmation engine, and in interface. The display overlays a virtual file document onto a tangible object. The physical identification verification engine receives biometric data for a witness and confirms the witness's identity. The display displays a gesture motion from the signor. The gesture capture engine captures a gesture motion from the witness. The gesture capture engine generates a witness digital signature based on the captured gesture motion from the witness. The gesture capture engine generates a witness transfer token, the witness transfer token comprising the witness digital signature based on the captured gesture from the witness and the witness identity confirmation token. The interface communicates the witness transfer token to a server.
