You need DRM software... I have tried Locklizard, it looks very good... and very expensive too. I am still thinking there may be a cheaper alternative... but I think it is unlikely to find a Gnu version of those programs... ok, I know free software doesn't mean absence of copyright, but I *feel* Gnu people would focus the subjet in a different way... it's not something I can express with words, just a "feeling". What locklizard does, it is to encrypt the document, lets say, a pdf file, which now can only be open with a special (free) viewer... basically, a pdf viewer with other functions (FileOpen, another DRM company, uses a pluging for adobe acrobat reader). The viewer checks for a user ID in the computer (which is sent to the user, and I don't know how do it identifies the computer... but supposedly, it can't be copied to another computer), and then connects to an internet hosted database, checks the user rights to access the document, and then grant or deny the document. It can be configured to restrict some rights, or everything, and also the frequency (for each document) the reader checks the current status of the user, in the online database. They have solutions for websites too, but I don't know how does it work. I write this just to see if this is what you need... and maybe somebody will say: "hey, you are wrong, there are free software alternatives for that". Best Regards P.S: sorry for the off topic, I don't intend to keep on the subject, unless it returns to gpg, or unless other people is not against this subject. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQEcBAEBCAAGBQJIdeywAAoJEMV4f6PvczxAVJYH/189egiTEFAa2Zq+WFF3lKps 3+uuhwvPkq3sVin+wraQbE/YUeDtEnZvbnPk0LDF+q0xLDn4i5GS/tVDxZBYWA5k GterPmFCLPBhQSUR3BxojdMjZFQC7NIWVLOGhiKXlhgJnLHZ+KSRONI7xkJ98Zkm W/He+xo79SC8tJYbBW1fSVYenhiE0Thq4b/wHzuCi/9sTQOeVfssCpK6uAp5hdRG fmJZcYhjkXjh1rQwdDrAmp2mCaNMc+4y3fKjfZEjcG5gWnvEF+4sX3nj/oL3GXx/ 1FYLoa+HMvtkLb/ECk3EwxgNoQ/RPzloH6kXw8ZM+KuzQ16/VlDovYoBiGm9zC0= =xWM5 -----END PGP SIGNATURE----- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
