摘要： An object (10) to be checked has a scanning region (17) which contains a large number of magnetic elements (12) scattered at random. Each of the magnetic elements (12) is made up of an element main body formed of a high molecular material, and magnetic metal powder contained in the element main body. A processing apparatus (20) employed for checking whether or not the object (10) is authentic has a magnetic sensor (30) which is made up of a pair of MR elements (31,32) and a magnet (33). The MR elements (31,32) are arranged side by side in the direction in which the scanning region (17) is scanned. In the manufacturing process of the object (10), a detection signal which is based on variations in the output ratio between the MR elements (31,32) is produced, with the scanning region (17) of the object (10) being moved. The detection signal is converted into a cipher code, and this cipher code is recorded in a code indicator section. When the object (10) is checked for authenticity, a detection signal obtained by scanning the scanning region (17) is collated with the cipher code recorded in the code indicator section. When the detection signal and the cipher code agree with each other, the object (10) is determined as being authentic.

摘要： A number of bistable magnetic devices (12) are dispersed in a scanning region (13) of a checking object (10). Each bistable magnetic device (12) is formed of a nonmagnetic material which undergoes a drastic flux reversal attributable to the Large Barkhausen effect when subjected in succession to first and second external magnetic fields of opposite directions. A processing apparatus (21) comprises magnetic generators (31, 32) for generating magnetic fields of opposite directions, a transportation mechanism (26) for moving the checking object (10) at constant speed, and a coil (33) for detecting magnetic pulses, which are generated as the bistable magnetic devices (12) are subjected to the flux reversal, as changes of electromagnetic induction voltage. A detection signal for the scanning region (13) detected by the apparatus (21) is converted into a cipher code and then recorded in a code indicator section of the checking object (10). In checking the authenticity of the object (10), the detection signal obtained by scanning the scanning region (13) and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object (10) is real when the detection signal and the collation code correspond to each other.
