Counterfeit defenses built on paper have blind spots

Help Net Security

Overview

A recent study from the University of Maryland and North Carolina State University raises concerns about the effectiveness of paper-based counterfeit protection systems, specifically those using paper physically unclonable functions (PUFs). These systems authenticate products by relying on unique microscopic variations in the paper's surface. However, the research indicates that these systems can be disrupted or bypassed, potentially allowing counterfeiters to replicate products without detection. This finding is significant as it questions the reliance on paper PUFs in securing product authenticity, impacting industries that use these methods for anti-counterfeiting measures. The results suggest that companies need to reconsider their security strategies to address these vulnerabilities.

Key Takeaways

  • Affected Systems: Paper-based authentication systems, particularly those using paper PUFs.
  • Action Required: Companies should explore alternative authentication methods and improve existing paper PUF designs to enhance security.
  • Timeline: Newly disclosed

Original Article Summary

Counterfeit protection often leans on the idea that physical materials have quirks no attacker can copy. A new study challenges that comfort by showing how systems built on paper surface fingerprints can be disrupted or bypassed. The research comes from teams at the University of Maryland and North Carolina State University, and examines paper based physically unclonable functions, or paper PUFs, which rely on microscopic surface variations in paper to authenticate products. Paper PUFs have … More → The post Counterfeit defenses built on paper have blind spots appeared first on Help Net Security.
