Object anti-counterfeiting method and system

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 u
