140:, negated bitwise, and multiplied by 4. The weakness was that the hash function was stored in the firmware, so it could be completely understood and replicated. The PV2 used a better challenge and response mechanism. It was better not because it used a longer key (128 byte challenge, 128 byte response), but because the hash function was not stored algorithmically in firmware. Theoretically, the response could not be mathematically related to the challenge and the only correlation between the two could be a record saved in the manufacturer's database (which authorized processing systems would have to access to read pictures from the camera). In practice, though, only a few challenge/response pairs have been seen in the wild.

Public announcement of how to transform the single-use camera into a reusable camera, paired with the very low camera price, immediately created high demand for the Dakota
Digital. So Ritz began pulling the Dakota Digital out of its stores after learning of the hack, and the original camera soon

When introduced, the Dakota
Digital sparked massive interest, primarily due to its price tag: US$ 10.99. At the time, a digital camera of similar low-end resolution and functionality was in the $ 40–$ 70 range. The reason for the low price was that the Dakota Digital was a
