JumpDrive writes "I have been presented with a problem recently, which I know others have probably faced. During the last month, one of our customers accused us of providing another customer with their specification. So the question arose: how do we, or can we trace documents and find if they are being opened or used somewhere where they weren't intended. We don't want to be restrictive, because at times, we have people all over the place, but if one of our documents were opened in a foreign country, that would arouse suspicions. Most of our documents are made with MS office suite, and I have been thinking of working on a macro to ping a server, but that would require the user to enable the macros, and it would also require the insertion into about 1000 documents. But it's been difficult for me to find a solution that doesn't prevent someone in Omaha from opening a document for legitimate use and is not a solution that can easily be disabled or hacked around."
