Solution Overview

Problem

Users of handheld mobile devices face inconvenience due to repetitive login requirements when switching between multiple applications, leading to delays in tasks such as online shopping and financial transactions.

Innovation Solution

A system that generates a master token with a quality score during initial strong authentication, allowing sub-tokens to be created for each app, which can skip or shorten the login process by leveraging the security provided by the initial login, enhancing user convenience and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each app requires its own login process, then security is maintained for each application, but user convenience deteriorates due to repetitive logging in when switching between multiple apps

Engineering Contradiction:
ImprovesecurityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the login authentication into a master token component and app-specific sub-token components. The master token contains user authentication credentials, while sub-tokens are generated for each app and contain references to the master token along with app-specific parameters. This segmentation allows the system to maintain security verification for each app while enabling automatic authentication through the sub-token mechanism, eliminating repetitive login requirements.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple login processes are required for multiple apps, then each app's security is ensured, but time efficiency deteriorates due to delays when switching between apps

Engineering Contradiction:
ImprovesecurityVSAvoidtime efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements preliminary action by generating the master token once during initial user authentication and storing it on the device. When the user launches multiple apps, sub-tokens are automatically generated using the pre-stored master token, eliminating the need to perform the full login process repeatedly. This preliminary authentication setup significantly reduces time latency when switching between apps while maintaining security through the master-subtoken verification mechanism.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If a master token system with sub-tokens is implemented, then user convenience improves by skipping login processes, but device complexity increases due to token management mechanisms

Engineering Contradiction:
Improveuser convenienceVSAvoidtoken management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the master token as a multi-functional credential that serves all authenticated apps on the device. Rather than implementing separate authentication systems for each app, the master token provides universal access authorization, while sub-tokens handle app-specific parameters. This universal approach simplifies the overall system architecture despite the introduction of token management, as it replaces multiple independent login processes with a single unified authentication mechanism.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

Methods and systems allow a user to log in to a device so that a number of apps become accessible on the device without the user repeatedly logging in to each different app as the user launches multiple apps. A mechanism of providing a master token with a quality score and providing sub-tokens for each app that can use the sub-token and the score quality to evaluate the level of security provided by the initial login allows each app to skip its own login process and provides a level of enhanced efficiency and convenience for the user. A method includes authenticating a user; creating a master token on the user device; creating a sub-token of the master token for an app launched on the device; the app skipping the login process of the app in response to the sub-token so that the app proceeds directly to validating a transaction.
