05 Jul 2022 --- Researchers at Purdue University, US, are developing an edible “security tag” embedded into medicine to expose counterfeiters. The tag acts as a digital fingerprint for each drug capsule or tablet, using an authentication technique called “physical unclonable functions” – or PUF – which was originally developed for information and hardware security. PackagingInsights speaks to Young Kim, associate professor at Purdue University’s Weldon School of Biomedical Engineering, about the need for security tags for the pharmaceutical market. “The need for advanced authentication and anticounterfeit technologies for pharmaceutical products is ever-growing as the practices of medication counterfeiting become increasingly advanced during the COVID-19 pandemic,” says Kim.
