Abstract
Generally, this disclosure describes a system including a privacy aware DHCP service and a user device. The user device includes a trusted execution environment including a client privacy agent configured to request a first Internet Protocol (IP) address from a DHCP service and to determine a device privacy score based, at least in part, on a DHCP policy; memory comprising secure storage configured to store the first IP address; and communication circuitry configured to establish at least one connection between the user device and at least one entity over a network using the first IP address. The client privacy agent is configured to monitor communication activity over the connection(s), to update the device privacy score based, at least in part, on the communication activity, and to close the connection(s) if the device privacy score is outside an acceptable privacy score range, the acceptable privacy range bounded by a privacy threshold.
