Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication methods for hardware devices lack the same level of security and efficiency as traditional password-based methods, particularly in dynamically scheduled workspace environments.
Innovation Solution
A system utilizing a three-dimensional authentication object encoded with data, readable by LiDAR, and a bezel cover that switches between visible and concealed modes, combined with a mobile user device application, security camera, and networked workspace scheduling server, to authenticate user presence and access hardware resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional password-based authentication methods are used for hardware devices, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication with optical field-based authentication using LiDAR technology. The system uses laser scanning to read three-dimensional authentication objects, transforming the authentication mechanism from manual password entry to automated optical scanning and verification.
Solution Approach 2:
The patent introduces three-dimensional authentication objects with depth information encoded in multiple dimensions. Unlike traditional two-dimensional barcodes, these 3D objects contain authentication data distributed across height, width, and depth, requiring volumetric scanning by LiDAR to fully capture and verify the authentication information.
2Ease of operation
If three-dimensional authentication objects are always visible, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent implements a dynamic concealment system where the bezel cover can switch between transparent and opaque states. The cover remains opaque during normal operation to conceal the authentication object, and only becomes transparent when authentication is required and properly triggered, providing both security and accessibility at different times.
Solution Approach 2:
The system performs preliminary verification steps before revealing the authentication object. The mobile device must first present valid credentials to the conferencing device, which then triggers the bezel cover to become transparent, allowing the LiDAR scanner to read the authentication object. This preliminary action ensures only authorized users can access the authentication data.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security and efficiency by providing secure, multi-factor authentication using three-dimensional data objects, ensuring only authorized users can access workspace resources.
Implementation Method 1
A commonly used technique to determine the distance to each point on the target involves projecting an optical beam towards the target, followed by the measurement of the round-trip time, i.e., Time-of-flight (ToF), taken by the optical beam as it travels from the source to target and back to a detector adjacent to the source.
Implementation Method 2
In one embodiment, the conferencing device 400 includes a electrochromic bezel 401 configured to selectively conceal a LIDAR readable three-dimensional object 403
Data Source
AI summary
A workspace management system includes a networked workspace scheduling server. A conferencing device has a three-dimensional authentication object encoded with data that is read using light detection and ranging (LIDAR) and disposed behind a bezel cover. The bezel cover has at least a visible mode and a concealed mode. Upon the bezel cover being in a visible mode, the three-dimensional authentication object is visible to a LIDAR scanner, and upon the bezel cover being in a concealed mode, the three-dimensional authentication object is not visible to the LIDAR scanner. At least one security camera is configured to capture an image of the three-dimensional authentication object of the conferencing device. A mobile user device has an application installed thereon. A form authentication token associated with the mobile user device and encoded in the three-dimensional authentication object is retrievable by the application.
