System and method of vetting data

A method for managing access rights in a system including a first processor, a second processor, and an output device, the method comprising:

• at a rights enforcement device coupled to the first processor and the second processor:
• monitoring access of the first processor and the second processor to a hardware-implemented buffer access flag that grants access to the first processor to write data to an output data buffer in the output device;
• performing a hardware-based enforcement of a read-write permission of the second processor to the hardware-implemented buffer access flag;
• and
• performing a hardware-based enforcement of a read-only permission of the first processor to the hardware-implemented buffer access flag.

A system for vetting data comprising:

• an output device including an output data buffer;
• a first processor and a second processor coupled to the output data buffer, wherein the first processor writes output data to the output data buffer and notifies the second processor that the output data has been written to the output data buffer;
• and
• a hardware-implemented buffer access flag coupled to the first and second processors and to the output device, wherein the hardware-implemented buffer access flag grants access to the first processor to write the output data to the output data buffer, wherein the second processor has a permission to set the hardware-implemented buffer access flag and the first processor has a read-only permission to the hardware-implemented buffer access flag.
