Yes, I agree on passwords since the characters are the same every time. Does every iris scan produce the same hash though?

- solumunus 1y agoDoes your iris change between scans? I assume not.
- shaftway 1y agoDoes it need to be exactly the same? I assume it's a perceptual hash with a liveness check.
- kurikuri 1y agoThis feels like a flippant response. The question you responded to was ‘would the hash of the iris would be the same?’ It isn’t as if you’ll get an identical image of the iris every time, and hashes tend to behave chaotically for even slightly different values. If we compare this to something like password salting and hashing, it isn’t clear how we can maintain the constant salted hash value if we swap the password for a digital representation of a person’s iris.
- schwartzworld 1y agoDidn’t say literally the same thing. Obviously it would be more complex. but I’d assume a fair amount of consistency between scans. How else would you compare at all?
