Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices are vulnerable to unauthorized executable instructions, which can compromise their integrity and lead to loss of revenue for cellular carriers due to malicious or non-malicious software downloads, and existing solutions do not adequately detect or manage these threats effectively.
Innovation Solution
A system and method for managing executable instructions on wireless devices using a flexible authorization configuration, involving an authorization module that scans, detects, and manages unauthorized files, generating logs and reports, and enabling deletion or disabling of malicious files based on an authorization schema, with user manager oversight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If initial scan of downloaded application is performed, then detection speed is improved, but detection accuracy deteriorates because malicious intent cannot be fully detected
Solution Approach 1:
The patent performs preliminary scanning of downloaded applications to quickly identify obviously malicious files, then implements continuous monitoring of application operations to detect unauthorized actions. This two-stage approach combines fast initial detection with thorough ongoing verification, resolving the contradiction between detection speed and accuracy.
Solution Approach 2:
The system maintains continuous monitoring of application operations after initial download and scan. Instead of performing a single static analysis, the system continuously observes application behavior during execution, enabling detection of malicious intent that may not be apparent from initial scanning alone.
2Measurement precision
If comprehensive monitoring of application operation is implemented, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the monitoring system observes application operations, compares them against authorized actions, and triggers responses when unauthorized actions are detected. This automated feedback loop enables comprehensive monitoring without requiring constant human intervention, managing system complexity while maintaining high detection accuracy.
Solution Approach 2:
The system enables wireless devices to autonomously monitor and detect unauthorized executable instructions on their own devices. Each device performs self-monitoring and can automatically respond to threats, eliminating the need for external monitoring infrastructure and reducing overall system complexity while maintaining high detection capability.
3Adaptability or versatility
If third party applications are allowed, then device versatility is improved, but device security deteriorates due to potential malicious downloads
Solution Approach 1:
The patent introduces an authorization module as an intermediary between third-party applications and the device's executable environment. This module scans downloaded applications, monitors their operations, and enforces authorization rules, allowing versatile application installation while maintaining security through intermediate verification and control.
Solution Approach 2:
The system performs preliminary scanning and authorization checks on third-party applications before they can execute malicious code. By detecting and blocking unauthorized executable instructions in advance, the system prevents security breaches while still allowing legitimate third-party applications to enhance device versatility.
4Reliability
If unauthorized executable instructions are blocked, then device security is improved, but loss of information increases due to false positives
Solution Approach 1:
The patent replaces simple signature-based detection with behavior-based monitoring that observes actual application operations. Instead of blocking based on static characteristics that may cause false positives, the system monitors dynamic execution behavior and blocks only when unauthorized actions are actually observed, reducing false positives while maintaining security.

AI summary
Detection and management methods and apparatus for wireless devices (102) may include an executable instruction authorization module (114) operable to scan executable instructions on a wireless device, generate a log (120) indicative of a virus or otherwise unauthorized executable instructions based on a received authorization configuration (118), and forward the log to a user manager (108). The user manager may be operable to analyze the log and generate an authorization report (154) which may be viewable by an operator to determine the disposition of unauthorized executable instructions At least one of the executable instruction authorization module, the user manager, and the operator may be operable to generate a control command operable to delete, or otherwise disable, unauthorized executable instructions on the wireless device, or to restore the executable instructions on the wireless device
