Application Programming Interface (API) - a software interface used for interaction between the application and the operating system.    

BIOS   - the Basic Input/Output System is an OS-independent software designed for hardware operation support. An essential set of routines in a PC, which is stored on a chip and provides an interface between the operating system and the hardware.
BIOS Setup Utility - the utility for managing BIOS settings.   

COM-port - PC serial communication port.   

International Organization for Standardization (ISO) - International Organization for Standardization    

IRDA-port - s
tandard port for infrared data transmission and printing developed by the Infrared Data Association.   

ISO 7816 - l
ist of requirements to the readers' physical properties and smart card data exchange protocols.   

Key Storage Device (KSD) - the device used to store key information. The KSD may be a smart card, USB token, USB Drive etc. Dekart Logon uses the KSD to store user account data and user's biometric identifier. The KSD may be PIN code protected.
Microsoft Windows Installer (MSI) - the Microsoft Windows Installer (MSI) is a new installation service, enabling efficient installation and configuration of applications. For example, if an installation is unsuccessful, the installer restores the original state of the computer. MSI is built into Windows 2000 and Windows Millennium, and is freely available as a redistributable file for Windows 95/98 and NT 4.0.   

PCMCIA-port   - t
he port conforming with the PCMCIA specifications (Personal Computer Memory Card International Association)   

Personal Computer/Smart Card (PC/SC) - s
mart card readers' specifications supported by Dekart Logon.    

- t
he Personal Identification Number is used to confirm the authorization to access the data stored on the hardware key.    

PS/2-port -
the port used to connect the keyboard and the mouse to the PC.

Universal Serial Bus (USB)
- the Universal Serial Bus can be used to connect and disconnect peripheral devices without opening the PC case and even without shutting down the computer. The USB automatically detects these devices and configures the corresponding software.   

Authentication    -
his is a control process checking the authenticity of the user's identity, i.e. this process checks whether the user is the person he claims to be.   

Biometric Authentication
- user authentication based on verification of specific physical characteristics of the user by means of special biometric equipment. Biometric authentication can be based on verification of fingerprints, iris, voice, and other specific characteristics of human body.   

One-Factor or Standard Authentication
- a process controlling the authenticity of the user identity by standard means of the OS on the basis of a single factor: Something You Know – the user name and password.   

Two-factor Authentication
- a process controlling the authenticity of user's identity on the basis of the two following factors: "Something You Have – for example, the KSD device" and "Something You Know — for example, the user name and password, PIN-code".    

Three-factor authentication
- a process controlling the authenticity of the user's identity on the basis of the three following factors: "Something You Have – for example, the KSD", "Something You Know — for example, the PIN code", "Something You are – for example, the user's BIO ID".   

KSD monitor
- a
subsystem of Dekart Logon used to ensure additional computer security. It controls whether the Key Storage Device is available in the key reader or the USB port and locks the computer access when the key is removed.   

- a
software designed to control data input/output and interface, the applications/OS and the device connected to the PC.   

Identification -
control process using a unique identifier to determine whether the specific user is known to the system.   

   - a special process resulting in user authentication into the OS according to the user name and the password. After successful completion of this process, the user gains access to the OS according to the rights granted to that user.   

Smart Card
- a plastic card with an embedded microchip including the secured memory block with special hardware implementing the encryption algorithms — techniques for secret information encrypting/decoding. The smart card is connected to the computer by means of a special device — the smart card reader.   

Smart Card Reader
- this is a device used to operate smart cards. The reader can be both internal (connected as a standard 3,5" floppy disk drive) and external (connected by means of one of the following ports: COM, PS/2, USB, PCMCIA, IRDA, etc.)   

Strong Login
- this is a login process supplemented with strong authentication means, for example, the means of Dekart Logon.   

Screen Saver
- this is a dynamic or a static picture appearing on the PC screen after the key strokes or mouse movement have not been detected for a certain amount of time. It is used for two purposes: to save the screen from discoloration and prevent the computer from an unauthorized access.
