Zusammenfassung:An identification document which includes anti-counterfeiting features to provide tamper evidence in response to counterfeiting attempts includes an image receiving area having one or more fixed or variable items of information. In one embodiment, a pattern of material is embedded into the image receiving layer in the vicinity of the one or more fixed or variable items of information in a predetermined configuration. The embedded pattern is comprised of a solvent insoluble material such that attempted delamination of the document using solvents results in visually detectable tampering.
