<-bug food My employer has decided to release a software package which management has decided must be copy protected. I have been asked to find a good copy protection method. An ideal method would: 1) Allow the user to make backup copies 2) Prevent the user from using more than one of the copies (or the original) at a time 3) Be suitable for mass production 4) Work on several MS-DOS machines with any format Specifically, it must work with: IBM PC PC-DOS 1.1, 2.0, and 2.1 Zenith Z100 Z-DOS 1.25 and 2.0 NEC APC MS-DOS 2.0 and 2.11 DEC Rainbow MS-DOS 2.0 5) Allow the user to place his operating system on the protected disk and make it bootable (must work with all flavors of MS-DOS) 6) Allow the user to run the programs from his hard disk There are several companies out there which sell copy protection schemes to software manufacturers. If anyone on the net could point me to one (or more) that they have heard good things about, I would greatly appreciate it. If there is sufficient interest in this subject, I will compile any suggestions I get and post them to net.micro. One final question before I go. One method I am currently looking at is called Prolok. It is sold by Vault Corp. in Westlake Village, CA. If anyone knows anything about this company, I would be especially interested in hearing from you. Thanks for your time. -- David Shanks ..!tektronix!ogcvax!metheus!cdi!shanks Teneron Corp.
