products for certification bodies

The integrated examination systems developed by infolearn are used by bodies, recognized by the European Union such as the certification body DIPLOMA, and KeyCert ( 2006 to 2009).

Infolearn's integrated examination system consists of the following applications: Admin, Base and Client.
  • Admin is a web application located at the following address:
  • The Base and Client are stand-alone applications which are installed on the computers of the examination center. Base is installed on a computer which is located outside of the examination class, and Client is installed on all the computers of the examination class.
  • These three applications communicate with each other either via LAN or via internet. The communication is encrypted using the RC4 algorithm. In addition, the communication with the Admin is done via the HTTPS protocol which provides additional security.
  • The examination process begins and ends from Admin.
  • The system has a question database (QDB).
  • All the applications fully support the Greek language or the language that is desired by the body.
  • The system architecture is the following:

Admin specifications

  • Admin is an online application. It is the basic application of the certification system.
