Mobile Authentication Using Entry Coordinates and Input Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Password authentication systems in mobile terminals face security issues due to direct exposure of passwords, and requiring complex passwords complicates user convenience by necessitating additional memorization.
Innovation Solution
A method and apparatus for providing a combined authentication service that considers entry coordinates and input patterns when a user enters a password, allowing the user to maintain their existing password by verifying the entered numbers, coordinates, and patterns, while also optionally incorporating fingerprint information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password authentication system is used in mobile terminals, then authentication can be performed, but security is compromised due to direct exposure of passwords
Solution Approach 1:
The patent adds spatial dimension to password authentication by requiring users to enter passwords within specific coordinate ranges on the display screen. The authentication is performed by verifying both the entered password and the entry coordinates, transforming a one-dimensional password check into a two-dimensional verification process that includes position information.
Solution Approach 2:
The patent changes the authentication parameters from solely password-based to a composite parameter system including password, entry coordinates, and input patterns. By modifying the authentication parameters to include spatial and temporal characteristics, the system enhances security without requiring users to change their passwords.
2Reliability
If complex passwords are required to strengthen security, then security is improved, but user convenience deteriorates due to additional memorization requirements
Solution Approach 1:
The system automatically captures entry coordinates and input patterns during the normal password entry process without requiring additional user actions. The authentication mechanism serves itself by utilizing the inherent data generated during password input, eliminating the need for users to memorize or input additional complex information.
Solution Approach 2:
The patent transforms the authentication system to use existing user behavior data (entry coordinates and input patterns) as authentication parameters. This allows the system to enhance security using naturally occurring user input characteristics rather than requiring users to adopt more complex passwords or authentication methods.
3Ease of operation
If existing passwords are maintained without change, then user convenience is preserved, but authentication security is insufficient
Solution Approach 1:
The patent adds spatial verification dimension to the existing password authentication process. By requiring verification of entry coordinates in addition to the password itself, the system enhances security while allowing users to continue using their existing passwords without any changes.
Solution Approach 2:
The system pre-establishes coordinate ranges and input patterns during password setup, then uses these predetermined parameters for verification during authentication. This preliminary configuration allows the system to enhance security through additional verification parameters without requiring users to change their passwords.
Data Source
AI summary
Disclosed herein are a method and apparatus for providing a combined authentication service. Combined authentication information is set by acquiring an entry window location and authentication characters from a user, an entry window including the entry keypad is displayed at the entry window location, entry information including entry characters and entry coordinates is acquired from the user via the entry window, and combined authentication is performed by verifying the entry characters and the entry coordinates, thus strengthening the security of authentication of a mobile terminal while maintaining the user's existing password. Further, if a region to which the password entry coordinates are to be mapped is selected when the user sets a password, authentication is performed by additionally considering mapping coordinates in addition to the password even if the user enters the password into the existing password entry window, thus strengthening the security of password authentication.
