Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices, particularly smartphones, are vulnerable to malware and malicious communications, which can lead to unauthorized access, data theft, and other security threats, as existing protection measures are insufficient.
Innovation Solution
A comprehensive security system for mobile devices that includes features such as validation of SMS senders, protection against fake base stations, data encryption, SOS messaging, and user data deletion, along with anti-virus and anti-spam modules to control third-party applications and detect unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive security validation features are implemented (SMS sender validation, base station verification, application control), then security protection capability is improved, but device complexity increases
Solution Approach 1:
The security system is divided into multiple independent modules: SMS validation module, base station verification module, application control module, and data protection module. Each module handles specific security tasks independently, allowing comprehensive protection while maintaining manageable system complexity through functional segmentation.
Solution Approach 2:
The patent introduces intermediary validation mechanisms such as SMSC number verification for SMS authenticity, base station coordinate verification for location authenticity, and security module intermediaries that stand between applications and system resources. These intermediaries add validation layers without requiring complete system redesign.
2Reliability
If multiple security validation features are added (SMS validation, base station verification, application monitoring), then security protection is improved, but processing time increases
Solution Approach 1:
The system performs preliminary validation by pre-verifying SMS sender numbers against authorized lists, pre-validating base station coordinates before connection, and pre-approving applications before installation. This preliminary action prevents malicious entities from entering the system, reducing the need for continuous complex monitoring during operation.
Solution Approach 2:
The patent replaces complex continuous monitoring mechanisms with simpler verification methods: substituting continuous application behavior analysis with initial installation validation, and substituting real-time communication monitoring with periodic base station verification. This substitution reduces processing overhead while maintaining security effectiveness.
3Reliability
If data protection features are implemented (encryption, data deletion, access control), then data security is improved, but ease of operation decreases
Solution Approach 1:
The security module operates autonomously to manage data protection: automatically encrypting sensitive data, autonomously deleting malicious applications, and self-managing access control lists. This self-service approach provides strong data security while minimizing user intervention requirements, thereby maintaining ease of operation.
Solution Approach 2:
The system creates and manages copies of security-critical data: maintaining copies of authorized SMS sender numbers, copies of approved application lists, and copies of base station coordinates for verification. These copies enable rapid validation without requiring users to manually manage security data, preserving ease of operation while ensuring data security.

AI summary
System for protecting a mobile device against malware or harmful communications via calls and SMSs. A security module for a personal mobile device protects the device (and the user) against malicious communication, unauthorized access to resources and user private data, and against other security threats. The security module includes a combination of some or all of the following features: control of third-party applications, validation of the SMS sender's number, protection against fake contact name of the SMS sender, collection of data about fraudulent and spam SMS messages, robust sending of SOS SMSs and SOS e-mails with geographic coordinates of the mobile device, verification of validity of the base station, deletion of user data from a mobile device remotely, locking of a phone until the password is entered and filtering calls and SMS messages.
