Identification system and method for identifying an object

An identification system for identifying an object, the identification system comprising:

• a plurality of sensing units for sensing a plurality of pressure values of a plurality of pressure points of a first object disposed on the plurality of sensing units;
• a storage module for storing a set of characteristic information of a second object;
• a computing unit electrically connected to the plurality of sensing units for choosing at least three maximum pressure values of at least three maximum pressure points from the plurality of pressure values of the plurality of pressure points after receiving the plurality of pressure values of the first object, so as to calculate a circumcenter reference point of a triangle formed by the at least three maximum pressure points to generate at least three distance characteristic values and at least three angle characteristic values corresponding to the at least three maximum pressure points, wherein each distance characteristic value corresponds to a distance between each maximum pressure point and the circumcenter reference point, and each angle characteristic value corresponds to an angle included between lines connecting two adjacent maximum pressure points and the circumcenter reference point;
• and
• an identification unit electrically connected to the storage module and the computing unit for comparing the set of characteristic information with the at least three distance characteristic values and the at least three angle characteristic values, so as to indentify whether the first object corresponds to the second object.
