Another angle: in chemistry, "Ni" is the symbol for Nickel, but that seems unrelated. Maybe "SSN" as Semiconductor Storage Node or Silicon Semiconductor Network? But why "i999"? That's unclear.

I'll start by breaking it down. "S" could stand for various things: Security, System, Standard. "S" again—maybe Service System Number? Then "Ni"—maybe Nickel, or a placeholder for a letter.
