Multi-Terminal Biometric Authentication with Context Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods using biometric information, such as fingerprints, are vulnerable to unauthorized access as the information can be copied, leading to a need for enhanced reliability and security in authentication processes.
Innovation Solution
A method and apparatus that collect and combine biometric information from a first terminal with context information from a second terminal, performing authentication based on both types of information and using auxiliary authentication if the primary authentication fails, thereby increasing reliability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is performed using only biometric information from a single terminal, then the authentication process is simple and fast, but the reliability and security are insufficient because biometric information can be copied
Solution Approach 1:
The patent combines biometric information from a first terminal with context information from a second terminal to perform authentication. This merging of multiple information sources enhances authentication reliability by preventing unauthorized access through copied biometric data, while the systematic integration of these sources manages the overall system complexity
Solution Approach 2:
The patent introduces context information as an intermediary element that mediates between the biometric information and the authentication decision. This intermediary provides additional verification layers (location, time, device characteristics) that enhance security without requiring complete system redesign
2Reliability
If authentication requires multiple types of information from multiple terminals, then the security and reliability are enhanced, but the authentication process becomes more complex and time-consuming
Solution Approach 1:
The patent collects context information from the second terminal in advance of the authentication decision, preparing verification data (location, time, device characteristics) beforehand. This preliminary action allows the authentication process to proceed more efficiently by having verification data ready when needed
Solution Approach 2:
The patent divides the authentication process into separate information collection stages: biometric information collection from the first terminal and context information collection from the second terminal. This segmentation allows parallel processing of different information types, reducing overall authentication time while maintaining security
3Reliability
If authentication ends immediately when primary information is uncertain, then the process is efficient, but unauthorized access may occur; if auxiliary authentication is performed, then security is improved but user convenience decreases
Solution Approach 1:
The patent applies partial verification by using context information to supplement uncertain biometric authentication rather than requiring complete re-authentication. This partial action maintains security by adding verification layers while preserving user convenience by avoiding full authentication restarts for uncertain cases
Data Source
AI summary
The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A terminal is provided, which includes a sensing unit configured to collect authentication information; and a control unit configured to perform the authentication based on first authentication information and second authentication information, to control the sensing unit to collect third authentication information if it is determined that the authentication based on the first authentication information has succeeded and the authentication based on the second authentication information has failed, and to perform the authentication based on the third authentication information. Since the authentication is performed through a combination of biometric information and context information that are acquired from two or more terminals, reliability and security of the authentication can be heightened.
