Abstract

In health information systems in general a significant part of the stored data is of a confidential nature. An adequate protection is thus of vital importance. In most terminal based information systems the access protection is based on a password that the authorized user has to offer to the system when he tries to access it. In general there is a password for each individual user; two strategies can be distinguished:
  1. A.

    The system generates the passwords periodically.

     
  2. B.

    The user can choose his own password and ca]i be forced to change it periodically.
