It's not even really a "hash" in the sense that there's no predictable relationship of the outputs of similar inputs. The "hash" of my DNA is going to be far more similar to people in Seattle than to people in Tokyo, so it becomes far less meaningful to say my DNA matched and I was Seattle at the time.
- jimktrains2 7y agoHashes don't need to have large changes in output for small changes in input. A hash just transforms input data into a fixed space. For example, perceptual hash functions like Locality Sensitive Hashing (LSH) for text and pHash for images are designed so that small changes in input produce small to no change in output. Also, your DNA is an order of magnitude (or more) more similar to someone in Tokyo than it is different to someone in Seattle.
