Abstract
A system and method for a privacy mode are disclosed. A trusted execution environment and general operating system that has restricted access to the trusted execution environment are maintained on a processor. A privacy mode command indicating either one of a first value and a second value is received. A peripheral control interface, which is communicatively coupled to the trusted execution environment and otherwise communicatively isolated from the general operating system, is disabled when the privacy mode enable indicator has the first value and is enabled when the privacy mode enable indicator has the second value. An associated peripheral is disabled from providing signals to processing circuits when the peripheral control interface is in the disabled state and enabled to provide signals to processing circuits when the peripheral control interface is in the enabled state.
