A smart ring designed to prevent loss and a method for preventing loss.

Abstract

This invention discloses an anti-loss smart ring and an anonymous anti-loss method, belonging to the field of smart wearable technology. The smart ring includes a ring body and a built-in main control unit, a low-power wireless communication module, a wear detection module, a prompt module, and a power module. The ring automatically recognizes the off-hand state through wear detection, and sends an encrypted broadcast signal after being removed from the hand. It supports two modes: stand-alone near-field search and anonymous crowdsourced retrieval via the network. In network mode, third-party mobile terminals only anonymously report location-related information, and the cloud only sends the location to the owner's terminal. This invention achieves automatic anti-loss, encrypted transmission, dual-mode retrieval, and privacy protection, solving the problems of small retrieval range, poor privacy, and high power consumption of traditional anti-loss devices. It is suitable for various smart rings and other wearable devices.

Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to a BLE-based anonymous anti-loss smart ring and an anonymous anti-loss method. Background Technology

[0002] Existing smart rings or wearable anti-loss devices generally suffer from the following problems: 1) The anti-loss function relies on proximity alerts from the bound terminal; once the device is out of Bluetooth range, it cannot be retrieved. 2) Broadcast signals are unencrypted, making them vulnerable to illegal eavesdropping and tracking, posing privacy and security risks; 3) Crowdsourcing may leak third-party device information, resulting in insufficient protection of user privacy; 4) It cannot automatically identify the wearing / unwearing status, resulting in high power consumption and frequent false alarms.

[0003] Existing technologies struggle to simultaneously achieve low power consumption, automatic anti-loss, short-range search, wide-area crowdsourced retrieval, and anonymous privacy protection. Therefore, there is an urgent need for an anonymous anti-loss smart ring solution that balances security and practicality. Summary of the Invention

[0004] I. Purpose of the Invention This invention overcomes the shortcomings of existing wearable anti-loss devices, such as limited retrieval range, poor privacy protection, insecure broadcast signals, high power consumption, and high false alarm rate. It provides an anonymous anti-loss smart ring based on BLE and an anonymous anti-loss method, which realizes automatic off-hand detection, encrypted broadcasting, single-machine close-range search, and anonymous network crowdsourcing retrieval. While improving the anti-loss retrieval rate, it strictly protects the privacy of the owner and third-party users. II. Technical Solution

[0005] (1) Product Plan An anonymous anti-loss smart ring based on BLE includes a ring body, which has a built-in main control unit, a low-power wireless communication module, a wear detection module, a prompt module, and a power module.

[0006] The wear detection module is used to identify whether the ring is being worn; when it is detected that the ring is not being worn, the main control unit controls the low-power wireless communication module to enter the anti-loss broadcast mode and periodically send encrypted broadcast signals.

[0007] The smart ring supports two retrieval modes: Standalone retrieval mode: Paired terminals directly receive broadcasts to enable nearby retrieval prompts; Network retrieval mode: After the ring is marked as lost, mobile devices within the same ecosystem anonymously scan and report the information to the cloud, and the cloud will only push the location to the owner.

[0008] Furthermore, the wear detection module employs at least one of contact or non-contact detection methods.

[0009] Furthermore, the broadcast signal is encrypted, and only the owner and the cloud can decipher it.

[0010] Furthermore, third-party terminals only anonymously report signals, time, and location, without carrying device identifiers.

[0011] Furthermore, the prompting module includes at least one of sound, vibration, and light prompts.

[0012] Furthermore, the owner's terminal can determine distance and provide proximity alerts based on signal strength.

[0013] (2) Methodology A method for anonymously preventing loss of a smart ring, including the following steps: 1) The ring uses a wear detection module to identify whether it has been removed from the hand; 2) Automatically sends encrypted broadcast signals after being released from the device; 3) The owner's terminal can locate the property at close range in standalone mode; 4) If the ring marker is lost, the loss information will be published in the cloud; 5) Third-party mobile terminals anonymously scan and report broadcast information; 6) The cloud sends the location to the owner, enabling wide-area retrieval.

[0014] Furthermore, third-party terminals do not parse broadcast content; they only upload it anonymously.

[0015] Furthermore, it automatically switches to stand-alone mode at close range to improve search accuracy. III. Beneficial Effects

[0016] 1. Automatic anti-loss when not in hand, low power consumption and no false alarms: The broadcast is only activated when the device is detected to be out of hand, which greatly reduces power consumption and improves battery life.

[0017] 2. Encrypted broadcasting to prevent tracking and eavesdropping: The broadcast content is encrypted and cannot be deciphered by unauthorized devices, protecting the owner's location privacy.

[0018] 3. Dual-mode retrieval, searchable both near and far: use stand-alone mode for precise searching at close range, and use anonymous crowdsourcing mode to expand the search scope at long range.

[0019] 4. Complete anonymity, protecting third-party privacy: Third-party devices only report information, do not upload their own IDs, do not leak privacy, and have higher user acceptance.

[0020] 5. Simple structure and easy to mass-produce: Based on a universal BLE and wear detection solution, it is low in cost and adaptable to various smart ring structures.

[0021] 6. Comprehensive patent protection: Dual patent rights for product and method, one patent protects the entire system, providing the widest range of protection. Detailed Implementation

[0022] Example 1: Smart Ring Structure 1) The ring body contains a main control unit, a BLE communication module, a wear detection module, a sound / light prompt module, and a battery.

[0023] 2) The wear detection module determines whether the wearer is wearing the item via capacitive touch.

[0024] 3) Once the detection is removed, the BLE module begins sending encrypted broadcast packets.

[0025] 4) When the owner's mobile phone approaches, it receives the signal in standalone mode and triggers the ring to vibrate.

[0026] 5) If the ring is outside the immediate vicinity, the user can mark it as lost in the app and enter network mode.

[0027] 6) After other user devices anonymously scan the encrypted broadcast, they upload their location and signal information to the cloud, which only pushes it to the owner.

[0028] Example 2: Anonymous Anti-loss Method Flow 1) The ring's wearing status is monitored in real time; 2) Automatically enables encrypted BLE broadcasting after the device is removed from the user's hands; 3) The owner can directly locate the item by ringing the doorbell within Bluetooth range; 4) The owner initiates a lost item marker, and a lost item task is sent from the cloud; 5) Third-party devices anonymously scan and upload location information; 6) Locations are aggregated in the cloud and then sent only to the property owner; 7) Automatically switches back to single-player mode for accurate positioning when the owner approaches.

[0029] This embodiment is only a preferred solution. Under the concept of this invention, conventional replacements for detection methods, encryption methods, prompting methods, and network networking methods all fall within the protection scope of this invention. Attached Figure Description
