MOBILE DEVICE SECURITY

摘要

A method of securing a mobile wireless telecommunication device to prevent or restrict access to data stored in the device. The method comprises firstly registering the device with a network-based server in respect of a given user. In the event that said user wishes to prevent or restrict access to data stored on the device when the user does not have access to the device but has access to an alternative communication device, the following steps are carried out. The user is authenticated, via said alternative communication device, to an IP Multimedia Subsystem network, and, on the basis of such authentication, the user is allowed to access the server and send to the server an instruction to lock said mobile wireless telecommunication device.
