The simplest thing is to encrypt the disk image. There are many disk encryption products on the market. For example, you could use PGP Disk. You'd make a master disk by creating a 500 (for example) Mbyte PGP Disk file, adding everything you want to it, closing it, then burning it onto a CDR. The user would put the CD in, mount the PGP Disk file (on the CD) in a pseudo-partition and have access to the data. For more information on this topic, visit these other searchSecurity resources:
