Hi: This is an interesting problem and I don't know if there is currently an answer however maybe Dux. could have a feature that would lock the document but in such a way where you could Braille but you couldn't edit copy or export. That way the only function that would be left is actual Braille production. -----Original Message----- From: duxuser-bounce@xxxxxxxxxxxxx [mailto:duxuser-bounce@xxxxxxxxxxxxx] On Behalf Of George Bell Sent: April 1, 2005 10:38 AM To: duxuser@xxxxxxxxxxxxx Subject: [duxuser] Re: Security issue Hi Eakachai This is a very difficult problem indeed. May I ask what country you are from? One possible solution that springs to mind is to perhaps zip the files up, but zip with a password. Students would then apply to you for a password. However, this would not stop a student passing on the unzipped documents. Depending on your country's laws, you might be able to make a clear statement of copyright, and additionally make it clear that anyone copying the material for financial gain would be liable to prosecution. However, you would then require to actually prosecute a few offenders in order to send a real message out. Does anyone else have any ideas?

I'm facing with a crucial problem regarding security and copyright. Commonly, I can't upload original *.dxb files on my official website. We prefer to convert all files into *.brf and ignore graphics braille unavoidably. Now we still confront a problem that some NGOs in my country who are currently coping with education for visually impaired students. We discover that they copy our files and remove my publishing text in order to claim for their profit. Once I was advised to run the header text separately for the odd and even pages. For example, header text on the left hand side may say "the title of the book", while the right hand say "published by my office name". This solution is not possible in Duxbury. Please give us some advices the way we can deal with this problem. With my best regards Eakachai _____ This Message has been scanned for viruses by McAfee Groupshield.
