I believe what really nails the security for Applied is that they also manipulate the plant DNA with an integrated marker so it is more than just the raw DNA. I think it is their secret process which locks down the security. The PUF solution is not an add-on process in the marking stage because the bit train is already intrinsic to the device. The sequence is picked up before packaging and recorded instantaneously for electronic verification via a secure server access. While DNA marking cost is virtually negligent, it is the cost of post-scanner verification/authentication via lab testing that may be not practical for small companies. Also, remember the other trade-off, PUFs are limited to semiconductors with latches or SRAMs and therefore, currently device application is limited. In the end, I think we might see hybrid security measures using multiple technologies across the supply chain.
Douglas, thanks for your engaging article. I am not sure, however, whether it is a vote of confidence in the APDN technology that is currently available, or a preference for the PUF technology under development. You had mentioned you were going to meet with the Applied DNA Science team with regard to costs and timetable, any news there? By the way, I understand APDN is working with the College of Nanoscale Science and Engineering in an effort to intergrate their DNA tech within computer chips, here's a link to the video/press release FYI..http://cnse.albany.edu/Newsroom/NewsReleases/Details/12-01-17/UAlbany_NanoCollege_Applied_DNA_Sciences_Partner_on_Nanochip_Anti-Counterfeiting_Program.aspx Thanks again!

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
