Doorbell Access Control Using Two-Factor Device Proximity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems and access control systems fail to authenticate devices and access credentials with two factors before taking action, which can lead to unauthorized access.
Innovation Solution
A doorbell device initiates a state change of an access control device or control panel using two-factor authentication, verifying that a first device is proximate to a second device and validating access credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two-factor authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The doorbell device acts as an intermediary that receives access credentials from a first device and verifies their validity before initiating state changes. This intermediary role allows the system to implement two-factor authentication without requiring the access control device itself to be overly complex, as the verification logic is centralized in the doorbell device.
Solution Approach 2:
The authentication process is segmented into distinct components: the first device provides access credentials, the doorbell device verifies validity and checks proximity of the second device, and only then initiates the state change. This segmentation allows each component to have focused functionality, reducing overall system complexity while maintaining security.
2Ease of operation
If access credentials are validated without two-factor authentication, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The doorbell device performs preliminary verification of access credentials and proximity checks before allowing any state changes to occur. This preliminary action ensures that only authorized users with valid credentials and proper device proximity can access the system, maintaining ease of operation for legitimate users while preventing unauthorized access.

AI summary
Systems and methods of a doorbell device initiating a state change of an access control device and/or a control panel responsive to two-factor authentication are provided. Such systems and methods can include the doorbell device receiving first access credentials from a first device, determining whether the first access credentials are valid, and determining whether the first device has been authenticated with two factors by determining whether an indication of two-factor authentication of the first device has been received from the first device or by soliciting and validating second access credentials from a second device. When the first access credentials are valid and the first device has been authenticated with the two factors, the doorbell device can transmit a state change command to the access control device that controls access to a secured area associated with the doorbell device and/or the control panel that monitors the secured area.
