Up to a point. Someone interested in monitoring what you do could still capture the display data and the data transmitted from whatever input devices you use. This is especially true if you plug this into a computer of uncertain provenance, but still potentially true for a monitor, TV, etc. It definitely seems like an improvement in security over just booting or running a VM from a secure flash drive, though.
