Apple introduced many interesting innovations at WWDC-2019. One of them was a new application «Locator» for iOS, iPadOS and macOS. The program combines the capabilities of services «Find iPhone» and «Find friends».
The application allows you to find out the location of friends and relatives, transfer your data and find missing devices. Besides, curious offline search option also appeared in Latitude. It allows you to find even devices that are turned off or in sleep mode.
How iPhone Offline Search Works, iPad and Mac
It is easy to understand the mechanism of searching for a device that works and finds it on the web. But what to do with the computer or smartphone turned off, which is no longer available? Apple tried to solve this issue using crowdsourcing. A special system has been created, which enables iPhone or iPad (even without a SIM card and internet connection) send information about your location to the world using Bluetooth. Naturally, this signal is encrypted with high quality. With this feature, you can even find a laptop with a closed cover.
When you turn on the lost device, it will immediately generate a special encrypted signal, which can be received by any Apple device that’s nearby. A complete stranger and a stranger can be a relay of coordinates. His device without the knowledge of the owner will catch a signal, will check its location and encrypt data about it using the public key received from the missing device.
Location information is encrypted so securely, what to locate a fellow, abiding lost (with Wi-Fi off or without a SIM card), only the second host device can. Apple emphasizes, that geolocation data of a lost device cannot be decrypted even by it, although this information gets to it on the server. The owner needs to activate the function «To find» and get that very encrypted message, which will reveal the location of the lost device.
