Methods and systems are provided for the secure entry and maintenance of data entered via a user input device. A computing device includes a secure processor coupled to one or more user devices. The user devices may be peripheral devices coupled to the secure processor via a wired connection such as a USB or PS/2 interface or via a wireless connection such as Bluetooth. A security boundary associated with the secure processor is established using hardware or cryptographic techniques. Input data received from the user device is stored within the security boundary. Additionally, the secure processor is configured to identify the user peripheral device coupled to the secure processor and to determine whether a request received to access the user peripheral device is allowable based on security policies defined for the user peripheral device.
