Abstract: A method of managing filesystem elements between a user device and a network connected to the user device comprising: receiving a request related to a filesystem element operation over the network; performing the filesystem element operation; updating a local metadata file based on the operation; downloading an encrypted network metadata file including data of the filesystem on the network from the network to the user device. The method comprises decrypting the encrypted network metadata file on the user device with a network encryption key; and provided the network metadata stored in the network is newer than the updated local metadata file, merging the network metadata file stored in the network with the updated local metadata file to update the local metadata file. The method comprises encrypting the updated local metadata file on the user device with the network encryption key; and uploading the encrypted updated metadata file to the network.

Abstract: A method to configure a new IoT device using a smartphone with the IoT device configuration application/service installed. Once the user has added the configuration preferences after successful login to his account on the cloud service using secure communication channel (such as TLS), the user can scan the QR code printed on the device/paper shipped together with the device. After the QR code is scanned, the mobile application decodes the data contained in the QR code, verifies the digital signature, and automatically enables a Wi-Fi hotspot on the smartphone, based on the information retrieved from the QR code. Then, the mobile application informs the user to switch on the IoT device. Once the IoT device is turned on and boots completely, it connects to the hotspot on the smartphone using the default Wi-Fi SSID and PSK saved in its memory (the same as on the QR code).
