proportion of stamp A pattern detail in correct stamp registered and recorded in all system backgroundIs that
，
Wherein, the molecule is the total number of all pattern characters of the seal, m is the total number of all features currently scanned by the seal, each new scanning and determining a feature point, the value of m is increased by 1, the corresponding molecule determines whether to add 1 according to whether the pattern characters are present,the values of (2) will also iterate, achieving an iteration of the pattern properties,/->Registering certain pattern details scanned out by another correct seal recorded for the background of the system.
7. The method for encrypting the authenticity of the object seal by reverse verification of the stamp according to claim 6, wherein the method comprises the following steps: in the step S3, the method for calculating the coincidence between the stamps comprises the following steps: and (3) calculating the coincidence of the stamp A and all stamps in the pattern character, wherein the calculation formula of the coincidence X between the stamp A and the correct stamp is as follows:
，
the higher the coincidence X, the more similar the pattern details of the representative seal A and the correct seal are, the more likely the correct seal is recorded in the library.
