Automated Flashing Device for Wireless Device Data Erasure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to effectively remove customer personal information (CPI) from electronic devices to prevent identity theft and ensure compliance with laws and industry standards when devices are returned or refurbished, as existing methods fail to ensure complete data erasure.
Innovation Solution
A system and method for flashing electronic devices, which includes a testing device with a processor and memory for executing a flashing application that detects and removes CPI, updates software, and reinstalls devices to a factory standard configuration, allowing for simultaneous processing of multiple devices from various OEMs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data erasure methods are used, then device processing is simple, but personal information may not be completely removed compromising security
Solution Approach 1:
The patent introduces a flashing device as an intermediary between the returned device and the processing system. This device contains a database of personal information locations specific to each device model and executes automated erasure procedures, ensuring complete data removal while keeping the overall system manageable through specialized intermediate hardware.
Solution Approach 2:
The flashing device automatically detects device models, retrieves appropriate erasure procedures from its database, and executes complete data removal without requiring manual intervention for each device. The system self-configures based on device identification, making the process both reliable and efficient.
2Productivity
If individual device processing is used, then each device receives attention, but processing time increases reducing productivity
Solution Approach 1:
The system pre-populates a database with device-specific personal information locations and erasure procedures for multiple device models. When a device is returned, the flashing device quickly identifies the model and retrieves the appropriate pre-configured erasure sequence, enabling rapid processing without sacrificing completeness or accuracy.
Solution Approach 2:
The flashing device is designed to handle multiple device models and types through a universal interface and database system. It can process different OEM devices using stored procedural knowledge for each model, allowing high-volume processing while maintaining model-specific erasure accuracy through centralized procedure management.
3Reliability
If comprehensive data erasure procedures are implemented, then security is improved, but processing complexity increases
Solution Approach 1:
The flashing device automatically performs device identification, procedure selection, and execution without requiring operators to manually configure erasure parameters for each device. The system self-manages the complex security procedures through automated detection and execution of model-specific erasure sequences from its database.
Solution Approach 2:
Complex erasure procedures are pre-configured in the database during system setup. Operators simply need to initiate processing, and the system automatically retrieves and executes the appropriate comprehensive erasure sequence for the detected device model, making complex security procedures as easy to operate as a single button press.
