How does space ID work?

Could you elaborate on how space ID operates in the realm of cryptocurrency and finance? I'm particularly interested in understanding its fundamental principles, the technologies it utilizes, and how it differs from traditional identification methods. I've heard it mentioned as a potential solution for secure and decentralized identification, but I'm curious about the nuts and bolts of how it actually functions. Could you explain the steps involved in setting up a space ID, the security measures it employs, and how it's being utilized in the finance industry today? Your insights would be greatly appreciated.
