AlpVision extends Cryptoglyph tech into document security

AlpVision has produced a modified version of its Cryptoglyph technology that is designed to protect high-security documents from data leakage.

The Swiss company has already applied a different form of Cryptoglyph as a covert way to mark and protect pharmaceutical and other packaging from counterfeiting. The new version is visible and 'robust', however, serving as a deterrent to the misuse of confidential documents.

Like its parent technology, the new Cryptoglyph process requires no special ink or taggants - in fact it can be printed using a standard laser printer - and consists of a pattern of tiny little dots which resist multiple photocopy passes and can be read using a simple flatbed office scanner.

The dots "enable immediate identification of both the source and the recipient of the document, even if only a fraction of the document is available," said AlpVision in a statement.

AlpVision will present the document-protection form of Cryptoglyph in public for the first time at the CROSS Security Printing Conference being held in Kuala Lumpur, Malaysia, November 18-19.
