Trust agents

A computer-implemented system for trust agents comprising:

• a storage comprising trust agent settings;
• sensors of a computing device adapted to generate signals;
• trust agents, each trust agent adapted to receive signals from one or more sensors including at least one hardware sensor, determine a trusted state or untrusted state based on the received signals from the sensors and the trust agent settings, and send an indication of the determined trusted state or untrusted state to a trust agent manager when the trust agent is enabled and to send an indication of the determined trusted state or untrusted state to the trust manager when the trust agent is disabled, each trust agent further adapted to be enabled and disabled independently of any other trust agent;
• the trust agent manager of the computing device adapted to receive the trust agent settings and store the trust agent settings in the storage, enable and disable any of the trust agents based on the trust agent settings, receive the indications of the determined trusted state or untrusted state from the trust agents which are enabled, and combine the indications of the determined trusted state or untrusted state to determine a security state, wherein the security state is a trusted state or an untrusted state, and;
• a security manager adapted to receive the security state from the trust agent manager, and enable at least one security measure based on the security state comprising enabling a lock screen of the computing device or disable at least one security measure based on the security state.

A system comprising:

• one or more computers and one or more storage devices storing instructions which are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• enabling two or more trust agents on a computing device;
• disabling one of the two or more enabled trust agents such that there are one or more enabled trust agents on the computing device;
• receiving a state determination from each of the one or more enabled trust agents, wherein the state determination indicates either a trusted state or an untrusted state, and wherein the state determination is based on signals received from at least one hardware sensor of the computing device;
• combining the received state determinations to determine a security state;
• and
• enabling or disabling, by the computing device, at least one security measure of the computing device based on the determined security state, wherein enabling at least one security measure comprises enabling a lock screen of the computing device.
