Decentralized Access Control for Cloud Services

A method of issuing a digital certificate comprising:

• receiving, by a certificate issuer system, a digital certificate request from a user device associated with a user;
• receiving, by the certificate issuer system, from the user device, permission to access user information associated with the user and stored in an identity provider system;
• upon accessing the identity provider system, receiving, by the certificate issuer system, the user information from the identity provider system;
• creating, by the certificate issuer system, a digital certificate associated with certificate information comprising:
• identity information selected from the user information, a unique public key, a location associated with a distributed ledger system, and checksum algorithm information specifying a checksum algorithm;
• calculating, by the certificate issuer system, a checksum of the certificate information based on the checksum algorithm;
• transmitting, by the certificate issuer system, authenticity information associated with the digital certificate to the location to thereby cause the authenticity information to be recorded on the distributed ledger system,
• wherein the authenticity information comprises the checksum and the public key;
• and
• transmitting, by the certificate issuer system, the digital certificate to the user device to thereby cause the digital certificate to be stored in a memory of the user device.
