Biometric Authentication Device for Camera Lens Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional personal authentication systems using fingerprint sensors attached to lenses, such as camera lenses, face usability issues when the lens is temporarily lent or transferred, requiring operations like fingerprint data deletion and re-registration, which reduces convenience and operability.
Innovation Solution
An authentication device comprising an apparatus main body interface, a memory, a biosensor, and a processor that communicates with an apparatus main body to control a locking mechanism, allowing for secure and convenient personal authentication using biological information, enabling temporary use and transfer of usage authority without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint data is deleted and re-registered when lending or transferring a lens, then security is maintained, but usability and convenience decrease
Solution Approach 1:
The authentication system is divided into two independent components: the lens contains a fingerprint sensor for biometric data collection, while the authentication device stores and verifies the data. This segmentation allows the lens to be lent or transferred without requiring data deletion, as the authentication device maintains secure control over the biometric information.
Solution Approach 2:
The authentication device acts as an intermediary between the lens and the user. Instead of storing fingerprint data directly in the lens, the system uses the authentication device as a mediator to verify biometric data. This intermediary approach enables secure lending and transfer of lenses without compromising security or requiring data re-registration.
2Adaptability or versatility
If fingerprint sensor is attached directly to the lens, then authentication is integrated, but operational complexity increases for each use
Solution Approach 1:
The fingerprint sensor is extracted from the lens body and placed in a separate authentication device. The lens only needs to establish communication with the authentication device, which handles all biometric verification operations. This extraction simplifies the lens structure and reduces operational complexity while maintaining integration benefits.
Solution Approach 2:
The authentication device serves multiple functions: it stores biometric data, verifies fingerprints, manages lens authentication, and handles lending/transfer operations. This multi-functionality consolidates complex operations into a single device, reducing the operational burden on users while maintaining secure integration.

AI summary
According to an embodiment, an authentication device includes an apparatus main body interface, a memory, a biosensor, and a processor. The apparatus main body interface communicates with an apparatus main body controlling a locking mechanism. The memory stores therein biological information of a registrant. The biosensor acquires biological information The processor transmits information that an operator has been authenticated as the registrant with the biological information to the apparatus main body and controlles the locking mechanism, when the processor determines that the biological information acquired with the biosensor and the biological information of the registrant are pieces of biological information of the same person.
