Wireless Accessory Crowdsourced Location via Encrypted Key Relays

The patent introduces a server as an intermediary that receives encrypted location data from multiple electronic devices. This server acts as a mediator between devices that cannot directly communicate with each other or with the accessory, enabling location tracking without requiring the accessory to have wide area network capabilities. The server aggregates data from multiple sources to determine the accessory's location.

The patent replaces the traditional mechanical communication system (where the accessory would directly communicate with a tracking service via wide area network) with a cryptographic system. Location data is encrypted using the accessory's public key and transmitted through intermediate devices, substituting direct network communication with a cryptographic relay mechanism that works over peer-to-peer connections.

The patent applies preliminary encryption to location data before it is transmitted. The accessory's public key is used to encrypt the location information in advance, ensuring that even if the data is intercepted during transmission or storage, it cannot be read without the corresponding private key. This preliminary security measure protects the data throughout its lifecycle.

The patent implements selective decryption where only the authorized electronic device possessing the correct private key can decrypt and access the location data. Different devices have different decryption capabilities - the owner's device can decrypt, while other devices cannot. This creates local security zones where data is accessible only to authorized parties.
