COMMUNICATION SYSTEM, COMMUNICATION TERMINAL COMPRISING VIRTUAL NETWORK SWITCH AND PORTABLE ELECTRONIC DEVICE COMPRISING ORGANISM RECOGNITION UNIT

摘要

The communication terminal (2) of a communication system (1) comprises a virtual network switch (22) which can alter the destination of data being transmitted/received between the communication terminal (2) and a network (5 ) forcibly, wherein data is transmitted/received between the network (5) and t he communication terminal (2) through a portable electronic device (3). Various functions, including a security function, can be supplemented by providing t he function of software mounted on the portable electronic device (3) itself to the communication terminal (2). Even if a communication terminal connected directly with the network is not provided with such functions as VPN, firewa ll or virus check, high-safety communication can be ensured utilizing these security ensuring means mounted on the portable electronic device.
