Security Access Device Using Dual Transmitter Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems face challenges such as user inconvenience due to frequent login requirements, difficulties in switching between devices, and risks of unauthorized access when a computer is left unattended, as they often rely on reentering login credentials and inactivity timeouts.
Innovation Solution
A security access device and method that uses a transmitter to send identification and authentication information to a remote apparatus, maintaining access as long as the identifier is validated, employing technologies like RFID, Bluetooth, and encryption certificates for secure communication, allowing seamless transitions between devices and reducing risks of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inactivity timeout periods are used to automatically log out users, then security is improved, but user convenience deteriorates due to frequent reauthentication
Solution Approach 1:
The system performs preliminary authentication by capturing biometric data (fingerprint, iris, or facial recognition) before the inactivity timeout period expires. This advance authentication ensures security is maintained while preventing the need for users to re-enter credentials during the timeout period, thereby resolving the contradiction between security and user convenience.
Solution Approach 2:
The biometric authentication system enables self-service by automatically verifying user identity through physiological traits without requiring manual credential entry. The system serves itself by continuously monitoring biometric data and maintaining authentication status, eliminating the need for user intervention during extended idle periods while preserving security.
2Reliability
If users must reenter login credentials when switching devices, then security is maintained, but productivity deteriorates due to time loss
Solution Approach 1:
The biometric authentication system provides universal access across multiple computing devices by storing and recognizing unique physiological traits that remain consistent across different machines. This multi-functional approach allows users to authenticate once and access any device in the network, maintaining security while eliminating the need to re-enter credentials on each device, thereby resolving the contradiction between security and productivity.
3Device complexity
If traditional login systems are used, then implementation simplicity is maintained, but security deteriorates due to vulnerability to unauthorized access
Solution Approach 1:
The system replaces mechanical authentication methods (keyboards, password entry) with biometric sensing technology that captures physiological traits such as fingerprints, iris patterns, or facial features. This substitution maintains ease of use by eliminating manual credential entry while dramatically improving security through the uniqueness and difficulty of replication of biological characteristics, thereby resolving the contradiction between system simplicity and security.

AI summary
A security system and method is provided. An embodiment includes a security access device that includes a first transmitter for transmitting authentication to a computer and a second transmitter for transmitting verification information to a computer. The first transmitter is typically active and consumes power from the access device, while the second transmitter is typically passive, and consumes less or nil power from the access device. When the security access device is initially brought proximal to the computer and activated, the authentication information is sent to the computer and the user is logged in. Periodically, the computer will query the passive transmitter for verification information, to ensure that the security access device is still proximal to the computer.
