cf the pdf speca:
Creator: If the document was converted to PDF from another format, the name of the PDF processor that created the original document from which it was converted.
Producer: If the document was converted to PDF from another format, the name of the PDF processor that converted it to PDF.
so changing that is kind of cheating.

Dear Hans,
Thanks for the reference. Just to clarify, I only do this for VERY FEW documents I make, not all.
In some cases, I need to keep the author of the document unidentifiable for purposes of security, since otherwise, people who know how to look for metadata can easily identify that I am the author given the small # of people using ConTeXt. In my department at university I am the only one using it as far as I know. The 'IKTS-VTR' values above are just an abbreviation for my lab/course.
I bet that clever students can trace that down -)
Anyway, since it is not good practice, I will try to make do without this. in that case you probably need to hide more .. (when you process with \nopdfcompression at the top you can look in the pdf, i.e. compression is not encryption
one thing you can do is make a copy of lpdf-xmp.lmt and wipe all tricky values and then use that to make a format but if security is important, maybe better is to use "qpdf" to encrypt the file (you can then also prevent editing for instance) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
