Much progress has been made in digital microfluidic biochips (DMFB), with a great body of literature addressing low-cost, high-performance, and reliable operation. Despite this progress, security of DMFBs has not been adequately addressed. We present an analysis of a DMFB system prone to malicious modification of routes and propose a DMFB defense based on spatio-temporal randomized checkpoints using CCD cameras.
