This post made me wonder if this could be the origin of the checksum or certain checksum algorithms. A few minutes googling haven't led to any dates, so does anyone know what the history of the checksum is?
- pjc50 9y agoThe Luhn algorithm dates to 1960 and is still in use on credit cards: https://en.wikipedia.org/wiki/Luhn_algorithm https://en.wikipedia.org/wiki/Luhn_algorithm
- mikegerwitz 9y agoI can't say what the history specifically of checksums are off the top of my head, but error correction/detection dates back to at least the 1940s. Hamming(7,4) was created in 1950. Edit: Wikipedia: https://en.wikipedia.org/wiki/Error-correcting_code https://en.wikipedia.org/wiki/Error-correcting_code
