According to Janice Meraglia at Applied DNA Sciences, one of the companies that offer DNA authentication, DNA tagging is pretty much clone proof. The DNA sequence data is held in a database that is accessible only to laboratory staff, unlike the open databases used for traditional parts IDs. Cloners also don’t have access to an essential element of the DNA tagging process: the primer required to start the chain of DNA formation. Primers are small, custom-built sequences of DNA to which other specific sequences of DNA attach; they basically help DNA sequencing tools find the start of the DNA chain.

The downsides of DNA tagging are its expense and how long it takes for authentication. Right now, the list price of a single test is $250, according to Meraglia; this cost drops when an organization signs on for a regular supply-chain testing program. And, she says, the company is working on test equipment that could be used at a parts purchaser’s location to reduce the time lag, turning tests around in under an hour.

These issues have kept the technique from becoming widely adopted, but some U.S. government agencies have already begun to tag critical electronic parts. Meraglia thinks the technology will soon move into the financial services industry to verify critical parts of its infrastructure, such as the routers that move data.
