• The problem solved:  Traditional identifiers used for internal networks and the Internet, or extensions of these (password, fingerprint, etc.) are always stored in the computer. Because of this they may be stolen, changed. PASYS does not store the password on the computer, so the password cannot be stolen or changed.
  
• Definition:  PASYS (Personal Authentication System) is a personalised computer network / Internet access system in which the user’s access code is known to no one else other than the user. So even the system administrator is not able to abuse it.
  
• Introduction:  

  The system administrator constructs the computer system always assuming that behind the user identifier (login name, user name) there is a member of the organisation authorised to and identified by it. In order to ensure this identification in every network operation system the user name is protected by a password. The password that protects the user identifier is always on the server providing access, it can be accessed and changed using system administrator authorisation. (The most frequent form of “Social Hacking" is phoning the system administrator saying “I’ve forgotten my password”, who then changes it, even against the security regulations.)

  The PASYS access system does not identify on the basis of a user name – password pair. PASYS examines and accepts an electronically signed and encrypted access request, ensuring with this that the identity of the person initiating the access request is certified in accordance with the act on electronic signatures. As PASYS access can not be simulated even with administrator’s authorisation acquired on the server, so with the comparison of the server containing the data and PASYS it can be determined about every access or attempted access whether the person authorised used the system or not. Even if the system administrators of PASYS and the protected server containing the data work together they are not able to simulate the access of a third party. Handling PASYS access information does not require special IT knowledge, so it can be handled by any reliable member of the organisation.
