Abstract: Provided is a method for establishing a secure connection from a chip to a network. The method comprises sending a connection request with a decentralized identifier address, sending a request for getting a decentralized identifier, sending, to the network, the decentralized identifier, sending, to the chip, an authentication request with data, and determining and sending, to the network, authentication data, and authenticating the chip. It further include sending, to the ledger, a request for getting subscription data associated with the decentralized identifier address, verifying, whether the decentralized identifier address is associated with a subscription wallet address or a subscription address in an operator wallet sending, to the network, associated subscription data, verifying whether valid, and establishing, when valid, a connection to the chip.

Abstract: The invention concerns a method for interacting between a handheld device and a machine. The handheld device has an Internet browser for interacting with a physical element that is part of the machine. The physical element is a smart card web server for establishing a near-field wireless connection with the handheld device when the handheld device is in proximity of the machine. The physical element communicates over the air with at least a distant server, the server being able to update the content of the physical element.

Abstract: In a method for backing up personal data of a wireless communications network subscriber, the data is saved in a mobile communications device and backed up in a server of the network. A first subset of data is prepared from a set to be saved by a SIM card and is transmitted to the server for backing up. In an asynchronous backup mode, after the transmission of a subset of data to be backed up on the server, the backup is delayed for a certain period of time in order to free the mobile device for the user, and the backup is resumed at the end of this period.

Abstract: In a method for saving personal data for a subscriber to a wireless communications network, the data is being memorized in a mobile communication station and saved in a network server by means of a first communication channel and in a first saving mode. A determination is made whether the mobile device may establish a second communication channel and/or has an other mode of saving. If so, communication is opened on the second channel and/or according to the other mode, and the data is saved by means of the second communication channel and/or the other mode.
