Abstract
A data processing device including a microcontroller and configured to communicate with at least one remote system distributed on a network. The data processing device and the remote system are adapted to store a plurality of parameters identifying a user account belonging to a subscriber. The data processing device comprises a one-time parameter comprising the active account attached to the device designed for a one-time use, and a permanent parameter identifying an account attached to the data processing device, the permanent parameter being deactivated. The one-time and permanent parameter are stored in the at least one remote system, and the microcontroller is programmed to: use the one-time parameter to logon to the network when the data processing device is switched on; and exchanges the one-time parameter with the permanent parameter, upon successful logon to the network, the permanent parameter becoming the permanent active account. The first device and the at least one remote system store a parameter identifying a current active account attached to a second data processing device to replace, and upon successful logon to the network, a program automatically stored in the fi…
