Digital rights management ( DRM) is the management of legal access to digital content. Various tools or technological protection measures ( TPM ), [ 1] such as access control technologies, can restrict the use of proprietary hardware and copyrighted works. [ 2] DRM technologies govern the use, modification and distribution of copyrighted works ...
Copy-evident document. Copy-evident documents have features that make it detectable that a copy is not the original. In security printing, various methods such as void pantograph are used to create patterns that are hard to copy exactly and when copied inexactly produces an easily detectable image. This can include halftone screens that are ...
