Allowing consumers to identify counterfeit goods is a tricky and expensive problem, as many security measures such as holograms might be easily mimicked by counterfeiters. A new nanoscale printing technique, however, allows researchers to create labels that reveal a "watermarked" image when breathed upon by the consumer. The labels are scalable and durable, and can be applied to many surfaces, yet are beyond the hands of those who might try to mimic them to fool consumers. ..
