Artwork authentication and transaction method and system based on digital signature

Abstract

The invention discloses an artwork authentication and transaction method and system based on digital signature. The method includes the following steps: a scanning device acquiring an image of an artwork, recording and marking the scanned positions of the artwork; acquiring the scanned positions of the artwork and the image of the artwork, and saving the scanned positions and the image of the artwork to a preset artwork database after acquiring the digital signature of an appraiser; on the basis of the scanned position of the artwork, the image of the artwork and the digital signature, generating a corresponding authentication code and an authentication 2D code; receiving the scanned image of the artwork, based on the authentication code or the authentication 2D code, invoking the artwork database and acquiring the image of an object artwork, calculating the similarity between the scanned image and the scanned image of the object artwork, and inputting the result of the authentication based on the result of the calculation. According to the invention, the method combines fingerprint scanning, high-precision laser scanning and digital signature, increases the level of anti-counterfeiting, can effectively identify the identity of an operator, clarifies the responsibility of the operator, simplifies operation procedures of a platform, and increases operation efficiency of the platform.

Description

technical field [0001] The invention belongs to the technical field of artworks, and in particular relates to a digital signature-based authentication transaction method and system for artworks. Background technique [0002] The existing artwork appraisal and filing platform needs to use instruments to collect information such as the fiber state of the work, the ink adhesion and smudge state, the molecular structure and element composition of the pigment, etc. in the links of "artist identification" and "artwork technology filing". Scientifically analyze the information of the artwork. After the authenticity of the artwork is identified by ophthalmology, X-ray fluorescence energy spectrometer, A200 portable microscope and other instruments are used to detect the fiber structure, molecular structure, and elemental composition of the artwork. DNA data, which includes the microscopic appearance and material composition data of the works, including text, pictures, images, sizes ...

AI Technical Summary

Problems solved by technology

The whole process utilizes very complex technology, uses a variety of expensive equipment, and requires the staff of the authentication and filing agency to conduct identification. The identification process is complicated, the work efficiency is low, the identification cost is too high, and the promotion is difficult; The authenticity cannot be determined, which makes the whole set of art authentication technical solutions lose their original meaning
