System for authenticating image based on blockchain and hash encryption technique and method thereof

摘要

The present invention discloses an image authentication system and method based on a block chain and hash encryption technology. That is, the present invention extracts meta information from an image captured in a photographing terminal, generates a hash value using the image, registers the extracted meta information and the generated hash value in a blockchain server, and provides a specific image in the user terminal. In the case of requesting verification for a specific image based on the hash value related to, the verification function is performed by comparing the hash value related to the related image registered in the blockchain server with the hash value requested from the user terminal, and providing the verification result. , It is possible to increase user satisfaction by providing an efficient verification function for the image.
