Biometric Access Control for Ransomware Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current countermeasures against ransomware often compromise between convenience and reliability, with existing methods either degrading system convenience or posing risks due to high processing loads and management burdens for key information.
Innovation Solution
An unauthorized access detection system that uses a storage apparatus to store access destination data and a control apparatus to detect access requests, suspend unauthorized access, and perform authentication based on biometric information to control access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If confirmation screens are presented to seek user confirmation when unintended programs run, then security awareness is improved, but convenience for computer operation is degraded due to excessive confirmation requests
Solution Approach 1:
The patent introduces an intermediary authentication mechanism using biometric information (fingerprint, iris, or face recognition) that acts as a mediator between the security confirmation requirement and user operation. Instead of requiring repeated manual confirmations, the system uses biometric verification to authenticate users once, allowing seamless access without degrading convenience while maintaining security awareness.
2Reliability
If encryption processing and decryption processing are performed on suspected ransomware files, then detection capability is improved, but processing load increases significantly
Solution Approach 1:
The patent extracts and stores only the essential access destination information (file path, name, size, modification date) in a database rather than performing complete encryption/decryption processing on all suspected files. This extraction approach allows the system to detect and track ransomware activity using minimal data processing, significantly reducing processing load while maintaining detection capability.
3Reliability
If key information files and signature information are used for access control, then authentication reliability is improved, but management burden of confidential information increases
Solution Approach 1:
The patent implements a self-service authentication mechanism where the system automatically performs biometric verification and access control decisions without requiring manual management of complex key information files or signature information. The authentication process is automated and transparent to users, eliminating the management burden of confidential information while maintaining high authentication reliability through biometric data verification.
Data Source
AI summary
To detect an unauthorized access easily, conveniently, and reliably, an unauthorized access detection system stores data indicating an access destination of an unauthorized access to be detected, detects an access request, determines whether an access source indicated by the access request matches an access source stored in advance and also whether an access destination indicated by the access request matches the data stored, suspends an access to the access destination requested by the access request if it is determined that the access source indicated by the access request matches the access source stored in advance and also that the access destination indicated by the access request matches the data stored, receives an input of biometric information from a user, performs authentication based on the biometric information inputted, and controls the suspended access according to a result of the authentication.
