Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric authentication methods do not provide a secure and efficient means for authenticating a user's presence at a workspace, particularly in hybrid hoteling models where room usage is dynamically scheduled.
Innovation Solution
A workspace management system utilizing a mobile user device with a LIDAR camera and a conferencing device with an electrochromatic bezel cover, where a three-dimensional object encoded with symbology is scanned to generate an authentication token, which is verified through a remote cloud server, enabling secure access to hardware resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional barcode scanning is used for authentication, then the system is simple to operate, but the security level is insufficient for hybrid hoteling models
Solution Approach 1:
The patent transitions from two-dimensional barcodes to three-dimensional objects with depth information. The 3D barcode object includes depth variations that encode additional authentication data, making it resistant to photocopying and unauthorized reproduction while maintaining compatibility with mobile device cameras and LIDAR scanners.
Solution Approach 2:
The patent replaces traditional optical barcode scanning with LIDAR (Light Detection and Ranging) technology. LIDAR uses laser beams to measure depth and create 3D point clouds, providing more secure authentication by capturing the physical depth structure of the 3D barcode object rather than just its 2D visual appearance.
2Reliability
If biometric authentication is implemented, then security is improved, but the system lacks efficiency for dynamic workspace scheduling
Solution Approach 1:
Users receive push notifications with authentication instructions before arriving at the workspace. The 3D barcode object is prepared in advance and displayed on a conferencing device, allowing users to authenticate quickly upon arrival without waiting for manual verification or complex biometric processing.
Solution Approach 2:
The authentication system allows users to independently complete the check-in process by scanning the 3D barcode object with their mobile device. The system automatically verifies authentication tokens and updates workspace availability without requiring administrative intervention, thereby improving check-in efficiency.
3Loss of information
If centralized scheduling systems are used, then room availability can be tracked, but user presence verification is insufficient
Solution Approach 1:
The system implements a feedback loop where the mobile device captures the 3D barcode object, extracts authentication tokens, and sends verification requests to the server. The server responds with authentication results that update the workspace management system in real-time, confirming user presence and automatically adjusting room availability status.
Solution Approach 2:
The patent introduces an intermediary authentication token system that bridges the gap between physical presence and digital record. The 3D barcode object serves as a physical intermediary containing encoded authentication data, while the server acts as a digital intermediary that verifies tokens and updates occupancy information, ensuring reliable presence verification.
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 in authenticating user presence, allowing controlled access to workspace resources while ensuring secure and reliable interaction with electronic devices.
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
Three-dimensional imagers, ubiquitously available on consumer-grade mobile user devices, sometimes known as light detection and ranging (LiDAR) sensors, can be used to capture point depth information of objects or an area by illumination with an optical beam and by analyzing the reflected optical beam.
Implementation Method 3
a conferencing device with an electrochromatic bezel cover, where a three-dimensional object encoded with symbology is scanned
Data Source
AI summary
A workspace management system includes a workspace. A conferencing device has a display screen within an outer enclosure. A controlled light transmission region formed in the outer enclosure selectively blocks light or allows light to pass. A three-dimensional (3D) object, in which information is encoded in accordance with a symbology that employs all three dimensions of features that comprise the 3D object, is located beneath the controlled light transmission region and thereby selectively hidden or revealed. A remote cloud server, communicatively coupled to a cloud network, includes a processor and nonvolatile storage. The processor, using instructions stored in the nonvolatile storage, generates an authentication token, encodes the authentication token in a QR-Code, transmits the code to the conferencing device, authenticates the authentication token received over the network from a user device, transmits instructions to the conferencing device to reveal the 3D object, and authenticates 3D object information received.
