Look seriously at both Ray's SQL solution and Mark's Data-At-Rest-Encryption. The latter is a UV 10.2 enhancement. -Original Message- From: Ray Wurlod Sent: Thursday, November 29, 2007 1:59 PM If you were to convert the file into an SQL table, then you can grant SELECT privilege (or not) at the individual column level.

Augusto, Can you change your application to use OPENPATH rather than OPEN. This does not require a VOC entry just a path.

You would assign a password to the key - users who have the password can see the data. You have to be on a later release of UV or UD. Also, you can not encrypt a field that is indexed. Alternatively it may be easier to simply not show the data to users who shouldn't see it. It will depend on your application environment, etc. --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Need to partially hide a file
One approach would be to set up separate accounts for privileged vs. non-privileged users. That would give you two VOC files, and the paths to the data could be different for some or all of the files. Another approach is the following: In UniData this could be done by using environment variables, and assigning the variable with different values for some users than for others. For example: F @ENVVAR/PRIVATEFILE D_PRIVATEFILE User A (privileged) could have it set to C:\private. User B could have it set to . I don't know how much trouble that is to set up for windows users though. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Augusto Alonso Sent: Wednesday, November 28, 2007 1:46 PM To: u2-users@listserver.u2ug.org Subject: [U2] Need to partially hide a file Hi all.

RE: [U2] Need to partially hide a file
Augusto, sort of along the same line of thinking as Dave ... play with the user's logon as soon as they login... Modify your LOGIN VOC item so that it: a) Checks a Data Security flag for that specific user [ @logname = Item ID in DSA.Flags file] b) Open the Cust.Secure.Data file to a named common in a short program if they have clearance c) If they don't have clearance Open the Cust.Skinny.Data file to the same file name in the named Common The named common will follow the user to whatever account they logto (if you log them around in the app or if they can Logto). Downside: You will have to modify the code where you are opening this file in the App, since it will already be opened. BTW - This approach should meet PCI compliance, and others, since you are making a positive grant of access based on the User logon (rather than role based or menu based security). I would check the language of the controlling standard - sometimes they hint at the approach they want you to take.

Thanks Baker. Your suggestion is very wise, but the downside is too hard.

Re: [U2] Need to partially hide a file
I'm not sure this would work, but what if you created the file as a distributed file with 2 parts: part1 = 'public' data, part2 = 'secure' data. Those without security clearance would open just part1 and those with security clearance would open the distributed file which would give them access to both part files. How you do that in coding shouldn't be too difficult especially if you use named commons, I think. This is kind of a hybrid approach I just thought of based on the other suggestions. Also, some of the law we have would require the two partfiles to reside on different disks... HTH, Karl quote who=Augusto Alonso Thanks Baker.
