Remote Security Control for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional security systems for portable communication terminals rely on passwords, which are often easy to guess or forget, and do not function if no password is set, leaving them vulnerable to unauthorized access when stolen or lost.
Innovation Solution
A security system comprising a control device and portable communication terminal that includes a user instruction accepting unit, authenticating unit, and security program to protect information, allowing remote protection and cancellation of data through internet or wireless communication, using a ASP to manage user registration and process flags for secure information protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password is used to protect information in a portable communication terminal, then the information can be protected from unauthorized access, but the password becomes vulnerable to trial-and-error guessing by illegitimate users
Solution Approach 1:
The system performs preliminary actions by remotely activating protection functions and downloading security programs to the terminal before the user physically possesses it. This ensures that when the terminal is stolen or lost, protection is already in place, eliminating the need for the user to remember complex passwords while maintaining security.
Solution Approach 2:
The invention introduces a control device as an intermediary between the user and the terminal's security system. This control device remotely manages protection functions, authenticates users, and distributes security programs, thereby eliminating direct password dependency while maintaining reliable information protection.
2Reliability
If no password is set in conventional security systems, then the system does not function to protect information, but setting a password makes the system vulnerable to trial-and-error attacks
Solution Approach 1:
The terminal's security system operates autonomously by executing downloaded security programs that automatically activate protection functions. The system self-manages authentication through the control device without requiring user-configured passwords, thus maintaining security while avoiding password-guessing vulnerabilities.
3Reliability
If remote protection activation is implemented through a control device, then information security is enhanced, but the system complexity increases due to additional components like ASP and communication interfaces
Solution Approach 1:
The control device serves multiple functions: it authenticates users, activates protection functions, downloads security programs, and manages terminal security remotely. By consolidating these functions into a single multi-functional system, the patent reduces overall system complexity while maintaining enhanced security capabilities.
