A method of accessing data at a device, wherein the data is stored remotely from the device or in removable storage, comprises: sending a request from the device to access the data, the request including an identification code of a secure element or memory card associated with the device; verifying, based at least partly on the identification code, whether access to the data is to be allowed or denied; and allowing or denying the device access to the data accordingly. The data may be stored in a cloud computer system. The request to access data may also include a passcode or PIN or genetic or biometric information inherent to the user. The secure element or memory card may be a SIM, SE, TEE, micro SD, USB key or a smartcard. The entered PIN may be passed to the device SIM where the PIN is passed through an encryption algorithm which hashes the PIN with the SIM identification. Other inventions relate to providing to a user an invitation to access data with a verifiable code, registering a device with an access controller and allowing access to data only if at least one other device is already accessing the data. |
