Diff(Y-Y′)=0.01。
According to picture, contrast the similarity of algorithm calculated fingerprint:
a*diff(finger_pic_0-finger_pic_0),b*diff?finger_pic_end-finger__pic_end)=0.001)。
Can obtain thus:
Diff (vector[1], vector[1] ')=[A*0, B*0.01, C*0.001], when A=B=C=1/3, can obtain:
Diff=1/3*(0)+1/3*(0.01)+1/3*(0.001)=0.00367。
When another one people N inputs same password, obtain vectorial array vector[1] ":
Vector[1] "=[Character (" point ")], Y ", Z " }
Diff(vector[1 correspondingly], vector[1] ")=A*[diff (Character (" point ")-Character (" point "))]; B*[dfii (y-y3)]; C*[a*diff (finger_pic_0-finger_pic_0_d), b*diff (finger_pic_end-finger_pic_end_3)] }
Same method can obtain:
Diff (vector[1] ', vector[1] ")=[A*0, B*0.543, C*0.78], when A=B=C=1/3, can obtain:
Diff=1/3* (0)+1/3* (0.543)+1/3* (0.78)=0.441, visible N input point similarity is greater than the similarity of M.
