[comp.sys.mac] Hardware keys

davidd@ttidca.TTI.COM (David Dantowitz) (06/15/90)

One note in this thread mentioned the idea of using a hardware key
with each software product (as a method of adding a machine readable
serial number to a single CPU).

If low cost (unforgable) keys were available, would the accountability
of each copy lower the costs for software?  Current costs per unit are
in the vicinity of $30-$50 (U.S.).

Any thoughts on hardware keys?



One variation on this scheme was mentioned earlier: have users
subscribe to a local (network) service that provides access to
software.  The same service could authenticate a user and make an
appropriate charge to her account.  A 30 second call to an 800 number
wouldn't tie up a line, but would require that the user had a modem.

re: David Snearline's note

To provide for the student using the campus computers and perhaps one
own at home, the solution is to use a small ADB-type device that plugs
in easily.  (Such a device is on the market today, toward the $50
range and can be in series with the keyboard or mouse or at the end of
an ADB line.)

Yes, I would never support disk level protection -- too vunerable.

A better solution would be to use something built into EVERY CPU.  I
believe that every ETHERNET card has a UNIQUE address.  Some products
use this number as a protection against unauthorized use.
