Dual-Password Authentication for Emergency Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems for mobile terminals lack the ability to effectively protect users from coercive situations, such as theft or kidnapping, where unauthorized financial transactions or communications can occur, as they do not provide a means to convey emergencies or display alternative processing information.
Innovation Solution
A method and system for a mobile terminal that uses a password to activate special services, including financial transactions or communications, by comparing input passwords with stored normal and emergency passwords, and performing emergency networking processes or displaying virtual process information when the emergency password is entered, thereby enabling emergency notifications and secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication systems using smart cards or banking chips are implemented, then security for financial transactions is improved, but the system cannot protect users in coercive situations such as theft or kidnapping
Solution Approach 1:
The patent segments the authentication system into multiple password types (normal password and emergency password) stored in the UICC. This segmentation allows the system to handle different situations differently - normal transactions use the normal password while emergency situations can be signaled through the emergency password, resolving the contradiction between maintaining security and enabling emergency response
Solution Approach 2:
The patent changes the parameter of password functionality by introducing dual-password support in the UICC. The emergency password serves as a parameter change that transforms the authentication system from a single-function security mechanism into a multi-functional system that can both authenticate normally and signal emergencies, thereby improving adaptability without compromising the core security function
2Reliability
If emergency notification functionality is added to convey subscriber emergencies, then user safety in coercive situations is improved, but the system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the mobile terminal itself to perform emergency notification without requiring external emergency servers or additional authentication infrastructure. The terminal uses its existing communication capabilities and the emergency password mechanism to autonomously send emergency notifications, thus improving user safety while avoiding increased system complexity
Solution Approach 2:
The patent makes the existing mobile terminal components multi-functional. The UICC not only performs authentication but also stores emergency passwords and triggers emergency notifications. The messaging system serves both normal communication and emergency notification purposes. This universality allows emergency functionality to be added without proportionally increasing system complexity
3Reliability
If virtual process information is displayed to show normal processing during emergencies, then user security is improved by preventing unauthorized transactions, but information accuracy may be compromised
Solution Approach 1:
The patent applies preliminary anti-action by displaying virtual process information that shows normal processing is occurring, which prevents thieves from knowing that an emergency state has been triggered. This misleading information protects the user by preventing the thief from interrupting or altering the process, as they believe normal transactions are proceeding while actually emergency notifications are being sent

AI summary
A security service providing method using a mobile terminal password and a mobile terminal thereof. A normal password and an emergency password are stored in a smart card in advance. When a password for using a special service is input by a mobile terminal user, the input password is compared with the normal password and the emergency password. When the input password corresponds to the normal password, a special service requested by the user is provided. When the input password corresponds to the emergency password, a predetermined emergency process is performed. According to the emergency process, an emergency message is transmitted to the outside through a predetermined emergency networking process, predetermined virtual process information is displayed, or an abnormal process message for indicating unavailability of provision of the requested special service is displayed to the mobile terminal. Therefore, security is guaranteed and reliability is provided to the user who uses a special service through a mobile terminal by providing an emergency process performance function to the limited function of the password used for identification and authentication.
