IPC: H04N21/845
Filed: 2021-03-10
Abstract: A blockchain-based image forgery preventing system comprises: an inputting unit; an image dividing unit; a hash extracting unit; and a storing unit. The inputting unit is configured to receive image information from a photographing device. The image dividing unit is configured to divide the image information into a plurality of pieces of unit image data. The hash extracting unit is configured to calculate each hash value of the plurality of pieces of unit image data. The storing unit records each hash value of the plurality of pieces of unit image data in data blocks on a blockchain network. Each of data blocks includes a hash value of a preceding data block and a hash value of the unit image data. A hash value of preceding unit image data for the unit image data corresponding to each data block among the plurality of pieces of unit image data is recorded in a preceding data block of each data block. When using an image storing system, image data such as a video file is divided for each a predetermined unit time (e.g., frame). By storing the hash value for each divided part as a chain form for each time in the data block on the blockchain network, forgery or manipulation of the image information can be prevented.
