A smartphone is adapted, through software modifications, to provide multiple operating domains or domains that provide differing levels of security and reliability. Each operating domain is isolated from the others. Detection of unauthorized modification is provided in some embodiments. Cross domain activity notification is provided in some embodiments.

Multiple domain smartphone

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.

Cross domain notification

A commercial off-the-shelf smartphone is adapted, through software modifications only, to provide multiple operating domains or domains that provide differing levels of security and reliability. Each operating domain is isolated from the others. Detection of unauthorized modification is provided. Cross domain activity notification is provided.
