Edible silica tags could help prevent counterfeiting of medicines

17 June 2009

Cellular Bioengineering, Inc. (CBI) is developing a novel technology that can help prevent not only counterfeit medicine and other consumables, but can also be used in a wide range of often-counterfeit goods from airplane parts, great works of art, currency, electronic components, high value added ingredients, to cosmetics and luxury goods.

CBI's TruTag presents a breakthrough in the fight against counterfeit medicine, food, and consumer goods. The tags are made of the highest purity silica, rendering them biologically inert and edible. Each tag contains a custom-manufactured 'spectral signature' chosen from over one trillion possibilities. The unique choice of tag signature and product combination is the TruTag key to confirming the authenticity of the product, yet each tag costs less than a penny.

"The ability to authenticate and track individual pills is an exciting and potentially valuable tool in the effort to fight counterfeit pharmaceuticals," said Paul Kocher, Founder and Chief Scientist, Cryptography Research, Inc.

"I believe CBI is breaking ground on a new modality of safety, assurance and information essential for consumers and the US Government," said Admiral Thomas Fargo USN (Ret), Former Commander US Pacific Command. "This project has the potential to save lives and make a significant contribution towards the safety and authentication of wide ranging goods and products."

Ten percent of all drugs sold worldwide are counterfeit according to US FDA estimates. Annual global trade in counterfeit goods is estimated to be $600 billion and growing. Counterfeit goods and drugs pose a real threat to consumer safety as well as to companies whose brands are compromised and profits stolen.

At present, the primary means of tracking and verifying is through packaging and labeling. However, technologies such as radio-frequency identifiers (RFIDs) are not amenable to direct tagging of small or consumable items. The cheapest RFIDs are also relatively expensive at 7 to 15 cents each.

Package-based security is also inherently weak since the valued product is not the package, but the item contained. CBI is developing TruTag technology with the award of a co-operative agreement from the US government to help combat counterfeit drugs, and has established collaboration with Silicon Kinetics, Inc. of San Diego, California and its porous silicon labs in Maui.
