Problem • Counterfeiting of physical contents (e.g., Microsoft products, currency, Yeni Raki) • Current technique: Mostly relies on expertise of field investigators, assisted by conventional methods (e.g., holograms) • Goal: A more reliable technique, that yields 1. Information on content authenticity 2. Information on content origins for forensics analysis
Proposed Approach • Include a pictorial “invisibly watermarked” logo on physical products (paper, boxes, CD’s, etc.) • Embed identification data of the product ID (e.g., shipment information, customer ID), to be decoded reliably under printing & scanning (robust image watermarking) • Tamper detection & attack classification if the examined item is forgery (fragile image watermarking)
