Patent ID: 7571465

Claim:
An information exchanging system comprising a plurality of information communication terminals that exchange information including a plurality of information elements; wherein, of the plurality of information communication terminals an information communication terminal that transmits the information comprises: a security-coupling level setting unit which is configured to set a security-coupling level of the plurality of information elements; a dividing rule setting unit which is configured to set a dividing rule for dividing the information elements into a plurality of sets of loosely coupled information elements, based on the security-coupling level set by the security-coupling level setting unit; a dividing unit which is configured to divide the information elements into the plurality of sets of loosely coupled information elements, based on the dividing rule set by the dividing rule setting unit, wherein a security-coupling level of each of said sets of loosely coupled information elements is lower than the security-coupling level of the information elements prior to division; and a transmitting unit which is configured to transmit the plurality of sets of loosely coupled information elements divided by the dividing unit, and the dividing rule set by the dividing rule setting unit, and wherein, of the plurality of information communication terminals an information communication terminal that receives the information comprises: a receiving unit which is configured to receive the plurality of sets of loosely coupled information elements, and the dividing rule; and a re-structuring unit which is configured to re-structure the information from the plurality of sets of loosely coupled information elements, based on the dividing rule received by the receiving unit; wherein the information communication terminal that transmits the information further comprises: a naming rule setting unit which is configured to set a naming rule for assigning separate names to the information elements instead of their original names; a separate-name setting unit which is configured to assign separate names to the information elements instead of their original names, based on the naming rule set by the naming rule setting unit; and a naming rule transmitting unit which is configured to transmit the naming rule set by the naming rule setting unit, and the information communication terminal that receives the information further comprises: a naming rule receiving unit which is configured to receive the naming rule; and a name changing unit which is configured to change the separate names of the information elements to their original names, based on the naming rule received by the naming rule receiving unit.
