Hi I would like some advice on a security issue. The proposed development requires that very sensitive information be housed in Flash files.

This of course will all be password-protected access to the flash files. Now the main issue is the flash file will be cached on the computer, which is a potential security issue. If an unauthorised person has access to the computer and leaks the contents of the file this will have legal ramifications.

Is there a way to secure it so this is not possible or would streaming the content be a possibility?

Open to all suggestions
