Abstract: Encrypting and securely transmitting data between devices is disclosed. After a device obtains a request to purchase a prescription lens, including prescription data, to be inserted into a second electronic device, the prescription data is securely encrypted and transmitted to the lens manufacturer. The lens manufacturer may create a prescription lens and calibration data related to the lens. The calibration data can be encrypted and transmitted to a storage device for storage. The second electronic device can retrieve the encrypted calibration data from the storage device and utilize it to perform a full calibration of the device. The second electronic device can present images, in accordance with the calibration data, using a display through an optical path that include the prescription lens.

Abstract: The disclosed technology provides for secure data caching by an edge network for an electronic device. The secure data caching can be provided by including a personal edge network and a remote edge network in the edge network. The remote edge network may include storage nodes that are accessible by multiple users. The personal edge network may include devices that are associated with the electronic device and a user of the electronic device, and that have been enrolled as storage nodes of the personal edge network.
