Kidnap of AI / how to rescue it promptly?

AI’s learning exchanges massive data with SSDs and then stores it in NL-HDDs. Ransomware attack on such storage devices is a risk of kidnaping AI. In Japan (2024), 49% couldn’t be recovered within 1 month. Is 1 month termination in business operation acceptable? It might appear easy to recover manipulated data in data systems using timestamp and a supervising list of which data is stored in which storage device. Crackers manipulate not only data but also the supervising list. If we manually fix the manipulated supervising list, term to recovery will get longer as the number of storage devices increases. Device identification in each storage device may protect the supervising list from manipulation. In a hierarchy of device identification, there are device certificates and manufacturing records in OTP, and PUF, from the bottom. Because of a big remuneration from AI’s kidnapping, an easy solution with OTP makes nonsense. Implementation of PUF into each storage device may cost. We propose Physical Cyber Authentication (PCA) to ensure the same security level as PUF with easy and cheapest implementation like software and with no victim of robustness to temperature change.
