A privacy mode control apparatus, comprising: a peripheral control circuit (180, 182, 184) comprising a peripheral enablement control interface (170, 172, 174) settable between an enabled state and a disabled state, the peripheral control circuit configured to: remove power from at least a portion of an associated peripheral to disable the associated peripheral from providing signals to processing circuits based on the peripheral enablement control interface being in the disabled state; and enable the associated peripheral to provide signals to processing circuits based on the peripheral enablement control interface being in the enabled state; and a processor configured to maintain a trusted execution environment and a general operating system that has restricted access to the trusted execution environment, the peripheral enablement control interface being communicatively coupled to the trusted execution environment and otherwise communicatively isolated from the general operating system, and the trusted execution environment being configured to: receive a privacy mode enable indicator having a state indicating either one of a first value and a second value; set the peripheral enablement control interface to a disabled state based on the state of the privacy mode enable indicator indicting the first value; and set the peripheral enablement control interface to an enabled state based on the state of the privacy mode enable indicator indicating the second value. a peripheral control circuit (180, 182, 184) comprising a peripheral enablement control interface (170, 172, 174) settable between an enabled state and a disabled state, the peripheral control circuit configured to: remove power from at least a portion of an associated peripheral to disable the associated peripheral from providing signals to processing circuits based on the peripheral enablement control interface being in the disabled state; and enable the associated peripheral to provide signals to processing circuits based on the peripheral enablement control interface being in the enabled state; and remove power from at least a portion of an associated peripheral to disable the associated peripheral from providing signals to processing circuits based on the peripheral enablement control interface being in the disabled state; and enable the associated peripheral to provide signals to processing circuits based on the peripheral enablement control interface being in the enabled state; and a processor configured to maintain a trusted execution environment and a general operating system that has restricted access to the trusted execution environment, the peripheral enablement control interface being communicatively coupled to the trusted execution environment and otherwise communicatively isolated from the general operating system, and the trusted execution environment being configured to: receive a privacy mode enable indicator having a state indicating either one of a first value and a second value; set the peripheral enablement control interface to a disabled state based on the state of the privacy mode enable indicator indicting the first value; and set the peripheral enablement control interface to an enabled state based on the state of the privacy mode enable indicator indicating the second value. receive a privacy mode enable indicator having a state indicating either one of a first value and a second value; set the peripheral enablement control interface to a disabled state based on the state of the privacy mode enable indicator indicting the first value; and set the peripheral enablement control interface to an enabled state based on the state of the privacy mode enable indicator indicating the second value.
