Researchers have made a new type of watermark that remains invisible until a person’s breath reveals it. Engineers envision the technology being used as labels to fight the sale of counterfeit goods.
"One challenge in fighting counterfeiting is the need to stay ahead of the counterfeiters," said Nicholas Kotov, a University of Michigan chemical engineering professor who led the team that created the labels, in a statement. ”You can verify that you have the real product with just a breath of air.”
