A Secret Key Generation Method Based on Nameplate Image Features

Abstract

The embodiment of the present invention discloses a secret key generation method of a secret key generation system based on nameplate image features. The method includes: step 100, receiving the initial nameplate image, and intercepting the template image according to the size of the initial nameplate image, keeping the initial nameplate The size of the image is the same as that of the template image; step 200, delineate the encryption area of ​​the initial nameplate image, and encrypt the pixel value of each pixel in the encryption area by self-convolution; step 300, encrypt the self-convolution in the encryption area The pixel value of each pixel point and the pixel point on the template image is double-convoluted and encrypted; step 400, the generated encrypted image after the second convolution is used as an encrypted nameplate image, printed and pasted on the product for use. This solution turns the simple text on the nameplate into invisible information, ensures the protection of the nameplate information by encrypting the nameplate, and overcomes the disadvantages that ordinary nameplates are easy to be cracked, copied, stolen, and counterfeited.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of nameplate encryption, and in particular to a key generation method of a key generation system based on nameplate image features. Background technique [0002] After the product is put on the market, it will be fixed on the product to provide users with information such as the manufacturer's trademark identification, brand distinction, and product parameters. The nameplate is also called the nameplate. The nameplate is mainly used to record some technical data of the manufacturer and rated working conditions. for proper use without damage to the equipment. The materials for making nameplates are divided into metals and non-metals: metals include zinc alloy, copper, iron, aluminum, stainless steel, etc., but aluminum is mainly used for production, because the processed nameplates are relatively high-end and durable. Does not rust. Non-metallic materials include plastic, acrylic o...
