Data Processing Apparatus Activation Control via Removable Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data processing apparatuses face security issues as anyone with the password can activate the device, compromising data security.
Innovation Solution
A data processing apparatus is designed with a storage module for secret data, an acquisition module for removable media ID data, a generation module for authentication data, and verification modules to ensure only authorized users can activate the device by matching authentication and random keys stored on both the device and removable media.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password-based activation is used, then ease of operation is improved, but data security deteriorates
Solution Approach 1:
The activation authentication is segmented into two independent parts: a password input mechanism and a removable medium verification mechanism. The password handles user identity verification while the removable medium with stored authentication data handles device authorization. This segmentation allows each component to specialize in its function, maintaining ease of operation through password input while improving security through hardware-based authentication that cannot be replicated by password knowledge alone.
Solution Approach 2:
A removable medium serves as an intermediary carrier between the user and the data processing apparatus. It stores authentication data and random keys that mediate the activation process. The medium acts as a physical token that the user must possess (not just know), creating a two-factor authentication system where the intermediary object bridges the gap between user convenience and security requirements.
2Device complexity
If only password verification is implemented, then device complexity is reduced, but reliability of activation control deteriorates
Solution Approach 1:
Authentication data and random keys are preliminarily stored on the removable medium before the activation process occurs. This preliminary action of pre-loading security credentials onto the medium allows the activation control to be more reliable without adding complex real-time generation or verification systems during the actual activation moment. The heavy security computation is done in advance and stored, simplifying the activation process while maintaining high reliability.

AI summary
According to one embodiment, a storage stores secret data, first identification data, and a first random key. A generation module generates first authentication data from the secret data, first identification data, and second identification data of a removable medium. A first verification module determines whether the first authentication data and second authentication in the removable medium are identical. A second verification module determines whether the first random key and a second random key in the removable medium are identical, if the first and second authentication data are identical. An activation module activates the data processing apparatus if the first and second random keys are identical.
