Automatic Mobile Messaging Authentication via Device Identifier

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless communications devices face data loss when users switch or wipe devices, especially in PIN messaging applications, due to the lack of server-based data backup, leading to password fatigue and insecure password reuse.

Innovation Solution

A method for automatic user identification and authentication using a unique device identifier and e-mail address, which creates a registration ID and authentication token, allowing devices to automatically register with a server and access backed-up data without requiring user input, thus preserving device data across device changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a server-based authentication system with user IDs and passwords is implemented, then data backup and recovery capability is improved, but password fatigue and security vulnerabilities increase

Engineering Contradiction:

Improvedata backup and recoveryVSAvoidpassword fatigue and security vulnerabilities

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The device automatically performs authentication with the server using its unique identifier without requiring user intervention. The system serves itself by using the device's inherent characteristics (unique identifier) as credentials, eliminating the need for users to manage passwords while maintaining reliable data backup and recovery capabilities.

Inventive Principle:

Principle #25Self-service

2Device complexity

If direct peer-to-peer communication is used in PIN messaging, then device complexity is reduced, but data loss occurs when devices are switched or wiped

Engineering Contradiction:

Improvecommunication architectureVSAvoiddata loss on device switch

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

A server is introduced as an intermediary between devices to enable data backup and recovery. The server stores data associated with device identifiers and facilitates data transfer when devices are switched or wiped, preventing information loss while maintaining relatively simple peer-to-peer communication architecture.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If automatic device identification and authentication is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improveautomatic authenticationVSAvoidauthentication system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The unique device identifier serves multiple functions: it acts as both a device identification marker and an authentication credential. This multi-functionality simplifies the overall system by eliminating the need for separate authentication mechanisms, achieving automatic authentication with minimal added complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Automatic identification and authentication of a user of a mobile application entails receiving from the wireless communications device a unique device identifier and an e-mail address corresponding to the wireless communications device, associating a registration identifier with the unique device identifier and the e-mail address, generating an authentication token, and communicating the authentication token and the registration identifier to the wireless communications device.
