First magnetic tunnel is divided into three regions, is followed successively by first area, second area, the 3rd region in order；
Respectively calculate three regions in each pixel magnetic signal intensity and；
If it is determined that the magnetic signal intensity of first area and with the magnetic signal intensity in the 3rd region and being all higher than second area
Magnetic signal intensity and, it is determined that the magnetic signal intensity of first magnetic tunnel, which meets, to impose a condition.
7. it according to the method described in claim 4, it is characterized in that, further includes：
If the bandwidth chahnel of at least one first magnetic tunnel is not in bandwidth given threshold regional extent, Huo,Suo
State the bandwidth chahnel of at least one first magnetic tunnel no more than second magnetic tunnel bandwidth chahnel or, it is described at least
The magnetic signal intensity of one the first magnetic tunnel is unsatisfactory for imposing a condition, it is determined that the bank note to be measured does not have the magnetic of genuine note
Property feature.
8. a kind of magnetic false-identifying device of bank note, which is characterized in that including：
Magnetic values detection module, for detecting the magnetic values in the magnetic detection region of bank note to be measured；
Magnetic tunnel acquisition module, for if it is determined that the magnetic values in the magnetic detection region meet the magnetic threshold value item of setting
Part, the then at least one magnetic tunnel included according to the Information of the bank note to be measured acquisition magnetic detection region；
Magnetic false distinguishing module, for the passage magnetic characteristic according at least one magnetic tunnel and/or different magnetic tunnels
Between passage magnetic characteristic difference, magnetic false distinguishing is carried out to the bank note to be measured.
9. a kind of ATM including memory, processor and stores the computer journey that can be run on a memory and on a processor
Sequence, which is characterized in that the processor realizes the method as described in any in claim 1-7 when performing described program.
10. a kind of computer readable storage medium, is stored thereon with computer program, which is characterized in that the program is by processor
