Abstract: A method for ensuring that a computer readable information is authentic, including: generating a public key associated with the computer readable information, hashing the computer readable information to obtain a hashed computer readable information, encrypting the hashed computer readable information with a private key to create a digital signature, wherein the hashed computer readable information and the digital signature are stored on a block of a blockchain, authenticating the user computing device in response to a request from the user computing device to download the computer readable information, transmitting the public key and the digital signature to an authenticated user computing device, and instructing the authenticated user computing device to decrypt the digital signature using the public key to obtain the hashed computer readable information, and download the hashed computer readable information to the authenticated user computing system to retrieve the computer readable information.
