Apple released AIrTag since the release, everyone pays more attention to the anti-loss of items, Apple's Find My can find iPhone, Mac, AirPods, Apple Watch, today's Find My has not only been able to find Apple's devices, we first to understand the function of Find My.
- Share your location with friends and family
- Show your searchable device on the map
- Have specific devices play sounds, format, and more
- Add a new device
Find My workflow
1. After using the Find My app and a Find My peripheral connection, they negotiate a pair of key pairs. The Find My app holds the private and public keys; peripherals hold the public keys.
2. The peripheral, as a BLE beacon, constantly broadcasts a changing key (derived from the public key).
3, the surrounding Apple devices (iPad, iPhone, etc., can be other people's devices) after detecting this broadcast, will combine the key inside with their own positioning data, package and upload to the Apple server.
4. Find My app gets these positioning reports from the server and parses out the relevant positioning data.
In the future, Find My will be independently networked, and the addition of third-party devices will enrich the territory of Find My Network. Find My Network will provide third-party interfaces to provide better service. It will not compromise user privacy, and neither Apple nor third parties will know the specific location of the phone except for the user. Apple's Find My technology uses the Bluetooth wireless signal of Apple devices to create a network of devices to look for lost items, and they will work with third-party companies to create Find My Network anti-loss products.
Lenz Technology has many Bluetooth product solutions that use the Find My function.
