Digimarc security-class watermarking solutions offer an interconnected system of security features and anti-counterfeiting solutions. Brand owners and document issuers can effectively combat duplication, piracy and diversion of products or value documents. The core of Digimarc security-class watermarking technology is a method of placing machine-readable data into images. This embedded data, or digital watermark, is imperceptible to the human eye, but can be detected by Digimarc security-class readers loaded with patented software. Once embedded, digitally watermarked materials deliver unequaled protection.
