Wearable Cloud Anchor Authentication for Shared Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems lack a mechanism for authenticating requests from devices or users via assistant devices in shared settings, such as dorm rooms or office buildings, leading to unauthorized control of devices like lights or music systems.
Innovation Solution
The system employs wearable devices with image sensors to detect cloud anchors, which provide identifiers for network access and authentication, allowing users to authenticate access to controllable devices within a physical environment using visual or audial requests, and stores images of authenticated users for future access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication mechanisms are used in shared settings, then device control is accessible, but unauthorized access and security vulnerabilities occur
Solution Approach 1:
The patent introduces cloud anchors as intermediary elements that mediate between the wearable device and the assistant device. The cloud anchor contains authentication credentials and acts as a secure intermediary that verifies the wearable device's location and authorizes access without requiring direct authentication between the wearable device and assistant device, thus maintaining security while enabling convenient access in shared settings
Solution Approach 2:
The patent replaces conventional mechanical authentication systems (physical keys, manual passwords) with an optical-based system using image sensors to detect cloud anchors. The sensor on the wearable device captures images or video of the cloud anchor, and image recognition algorithms automatically extract authentication credentials, substituting manual authentication mechanics with automated optical recognition
2Reliability
If cellular services are used for network access, then connectivity is maintained, but battery power is consumed rapidly
Solution Approach 1:
The patent changes the network communication parameter from cellular to Wi-Fi by extracting Wi-Fi credentials (SSID and password) from the cloud anchor. This parameter change allows the wearable device to switch from high-power cellular communication to lower-power Wi-Fi communication, significantly reducing battery consumption while maintaining network connectivity in the shared environment
3Reliability
If manual authentication methods are used, then security is maintained, but user experience and access speed are reduced
Solution Approach 1:
The patent implements preliminary action by pre-configuring cloud anchors with authentication credentials before the wearable device needs access. The cloud anchor is set up in advance with the necessary authentication information, so when the wearable device detects the cloud anchor, authentication occurs automatically without requiring the user to manually input credentials or wait for authentication processes, thus eliminating authentication time loss

AI summary
Systems and methods are described for authenticating devices. The systems and methods may include detecting, by a sensor on a wearable device, at least one cloud anchor that includes an identifier associated with a network and configured for a physical environment. In response to detecting that a location associated with the at least one cloud anchor is within a threshold distance of the wearable device and detecting that the wearable device has access to the at least one cloud anchor, triggering extraction of the identifier from the at least one cloud anchor. The systems and methods may also include joining the wearable device to the network based on a received authentication corresponding to the extracted identifier.
