The invention discloses an object anti-counterfeiting method and
system. The method comprises the following steps of: firstly, setting a
label on an object to be anti-counterfeited, wherein the
label is provided with uniqueness; reading image information displayed by the uniqueness
label when anti-counterfeiting
verification is carried out, and encrypting the label by utilizing a private key to generate a
signature file; encoding the
signature file to generate an anti-counterfeiting code so as to set the anti-counterfeiting code on the object to be anti-counterfeited; obtaining anti-counterfeiting information on the object to be anti-counterfeited through an image capturing device on a user terminal device when the truth and false of the object to be anti-counterfeited need to be verified; decoding the anti-counterfeiting code to obtain the
signature file; and decrypting the signature file according to public key information corresponding to the private key to obtain and display the image information of the uniqueness label. By adopting the object anti-counterfeiting method and
system, the anti-counterfeiting effect can be improved.
