Solution Overview

Problem

The increasing number of connected devices, such as smartphones, tablets, and wearables, leads to cumbersome and tedious repeated login procedures, as users need to authenticate each device individually, which is inefficient and frustrating.

Innovation Solution

A method where a primary communication device recognizes a successful login and extends it to secondary devices by comparing physiological data captured by sensors on both devices, allowing credentials to be shared wirelessly without requiring users to re-enter login information on each device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If repeated login procedures are required for each communication device, then security authentication is maintained, but user convenience and operation time are deteriorated

Engineering Contradiction:
Improvesecurity authenticationVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces physiological data as an intermediary element that bridges the primary communication device and secondary devices. The primary device captures physiological data, transmits it to secondary devices, and uses it as a mediator to enable automatic credential sharing, thereby maintaining security while improving convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service authentication by automatically comparing physiological data between devices and sharing credentials without requiring manual user intervention for each device login. The system serves itself by automatically determining authentication status and transferring credentials.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual authentication is performed on each device, then security is ensured, but time consumption and operational efficiency are worsened

Engineering Contradiction:
Improveauthentication securityVSAvoidauthentication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The primary communication device performs preliminary capture and processing of physiological data during the initial login. This preliminary action enables subsequent automatic authentication on secondary devices without requiring repeated manual authentication, thereby reducing time loss while maintaining security.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical manual authentication process with an automated physiological data comparison system. Instead of requiring users to manually enter credentials on each device, the system automatically compares physiological data and transfers credentials, substituting manual operations with automated electronic processes.

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

3Measurement precision

If physiological data is captured and compared on each device, then authentication accuracy is improved, but device complexity and data processing requirements are worsened

Engineering Contradiction:
Improveauthentication accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the physiological data capture and comparison functions into a coordinated system where the primary device handles initial data capture and processing. By combining these functions and sharing the processed data with secondary devices, the system achieves high authentication accuracy without requiring each individual device to independently perform all complex processing operations.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method at a primary communication device for participating in log-in of a secondary communication device is suggested, where, upon recognizing a successful log-in of the primary communication device, a request for extended log-in to the secondary communication device is received from the secondary communication device. In response an instruction to initiate the requested extended log-in is transmitting to the secondary communication device. After having received physiological data, associated with the user of the secondary communication device and captured by at least one sensor of the secondary communication device, from the secondary communication device, and after the primary device has captured corresponding physiological data via the body of the use, the first physiological data is compared with the physiological data provided from the secondary device for determining whether there is a match between the compared physiological data. In case of a match at least one credential, required by the secondary communication device for extending said log-in to the secondary communication device, is transmitted to the secondary communication device, whereas no credential is transmitted to the secondary device in case no match is determined.
