Random Mosaic: Securing Hardware with Beans, Lentils, and Rice
2025-09-25
This paper introduces Random Mosaic, a novel physical security method. Traditional tamper-evident techniques are easily bypassed. The authors explore threats like supply chain attacks and Evil Maid attacks, analyzing existing methods (tamper-evident seals, glitter nail polish). They propose a new approach using colored beans, rice, etc., to create a unique, easily-verifiable mosaic pattern that detects unauthorized access. This simple, inexpensive method, combined with vacuum sealing, is suitable for short-term and long-term storage and shipping. The paper also introduces the Blink Comparison app for image comparison.
