Solution Overview

Problem

Conventional mobile phones using physical subscriber identification cards, such as SIM and UIM cards, are vulnerable to theft and misuse, leading to security risks and complications in deregistration processes when lost.

Innovation Solution

A fingerprint-based communication terminal and method that uses a fingerprint processing module to collect and process fingerprint information, obtaining a corresponding phone number through a network, allowing secure communication without the need for physical identification cards, enabling direct communication using a fingerprint phone number bound to the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a physical subscriber identification card (SIM/UIM card) is used in a mobile phone, then the phone can be used for communication, but the card can be easily copied and embezzled, leading to security risks

Engineering Contradiction:

Improvecommunication securityVSAvoidcard copying and embezzlement risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical physical card system with a biometric fingerprint recognition system. Instead of using a physical SIM/UIM card that can be copied or stolen, the system uses fingerprint sensors to capture and verify unique biological characteristics, storing encrypted fingerprint data in a secure chip. This substitution eliminates the vulnerability of physical cards while maintaining communication functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the identification parameter from physical card characteristics (which can be replicated) to unique biometric fingerprint parameters. The fingerprint template is extracted and stored as encrypted data, making it impossible to copy or emulate. This parameter change fundamentally addresses the security issue by using an immutable biological characteristic instead of a replicable physical object.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If a physical subscriber identification card is used, then the phone can be registered and communicate, but when the phone is lost, the user cannot deregister the phone in time, allowing lawbreakers to steal fees or cheat relatives and friends

Engineering Contradiction:

Improvephone registration and communicationVSAvoidderegistration time after phone loss

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent implements a real-time feedback mechanism where the authentication server continuously monitors and verifies fingerprint authentication status. When a phone is reported lost or the user initiates deregistration, the server immediately updates the authentication status and notifies relevant networks, preventing further unauthorized usage. This real-time feedback system eliminates the time delay inherent in traditional card-based deregistration processes.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system enables self-service functionality where the user can immediately deregister or lock the phone through fingerprint authentication without needing to visit service centers or wait for manual processing. The biometric verification allows the user to independently control phone registration status, eliminating the time loss associated with traditional deregistration procedures.

Inventive Principle:

Principle #25Self-service

3Reliability

If a fingerprint processing module is added to eliminate physical cards, then security is enhanced, but the device complexity increases

Engineering Contradiction:

Improvecommunication securityVSAvoidterminal structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the fingerprint sensor, processing unit, and secure storage chip into an integrated authentication module that works seamlessly with the existing communication infrastructure. The fingerprint processing functions are combined with the phone's existing processor and memory systems, avoiding the need for completely separate independent components. This integration minimizes the increase in device complexity while achieving enhanced security.

Inventive Principle:

Principle #5Merging (Combining)
