Patent number: 8594652
Abstract: A method for a mobile communication device to indicate activity associated with an operating domain includes establishing a plurality of operating domains for the mobile communication device each operating as an independent virtual machine. The method also includes providing a trusted indicator at the mobile communication device for indicating activity associated with a high-side domain. The method also includes providing an input on the mobile communication device for switching from a low-side domain to the high-side domain. The method also includes providing a trusted element for the mobile communication device that is independent of either the high-side domain or the low-side domain. The trusted element may be configured to receive a signal from the input for switching from the low-side domain to the high-side domain and to perform user authentication for switching from the low-side domain to the high-side domain.
