Detachable Storage Device Partition Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current USB memory devices lack robust security measures, allowing unauthorized access and data theft, as they can be easily cracked using brute force attacks and do not provide secure partitioning for different types of data, leading to potential exposure of sensitive information.
Innovation Solution
A detachable storage device with a user interface that requires a user code for authorization, which is entered offline before connecting to a digital device, ensuring that only authorized access is granted to specific storage partitions, using circuitry to encrypt and decrypt data and prevent unauthorized copying or access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single USB memory device stores multiple types of data (accounting, human resources, etc.), then data mobility is improved, but security is worsened because any employee with access can view all data types
Solution Approach 1:
The storage device is divided into multiple encrypted partitions, each storing different types of data (e.g., accounting, human resources). Each partition has its own unique encryption key, allowing selective access to specific data types while maintaining overall data security on a single portable device.
2Reliability
If password protection is implemented on USB memory devices, then data security is improved, but ease of operation is worsened due to brute force attacks and complex access procedures
Solution Approach 1:
The user enters the password offline (before connecting to the host computer) through the device's built-in interface. This preliminary authentication action ensures that only authorized users can access the device, and the host computer never exposes sensitive data to potential attacks.
Solution Approach 2:
The USB memory device itself acts as an intermediary authentication mechanism, requiring password entry through its own interface before allowing data access. This mediates the security requirement without burdening the host computer's security systems.
3Adaptability or versatility
If data is transmitted through networks, then data mobility is improved, but security is worsened due to interception risks and transmission errors
Solution Approach 1:
The invention extracts data from network transmission and stores it locally on portable USB memory devices. This eliminates the need for vulnerable network transmission while maintaining data accessibility, as users can carry encrypted data securely on physical devices.
4Ease of operation
If multiple password attempts are allowed, then ease of operation is improved, but security is worsened as attackers can systematically crack passwords
Solution Approach 1:
The device implements preliminary anti-action by locking the storage partitions after a predetermined number of failed password attempts. This prevents attackers from systematically cracking passwords while still allowing legitimate users reasonable access flexibility.

AI summary
A detachable storage device can comprise a memory, circuitry, and a user interface. The memory may comprise a storage partition. The circuitry may be configured to authorize access to the storage partition to a digital device when the detachable storage device is coupled to the digital device based, at least in part, on a user code. The user interface may be configured to receive the user code while the detachable storage device is within a detached state and provide the user code to the circuitry to allow access to the storage partition.
