A fingerprint USB drive was introduced before. It should be very safe and able to ensure that the data within the USB drive is not stolen. However, there is a downside: this fingerprint USB drive can only be used by yourself, others cannot use it. And it's unclear how much of an issue there would be in terms of technical implementation, or whether the cost would be too high, in which case, it would be difficult to popularize and apply. The password USB drive introduced today should also be pretty good. Only people who know the PIN can open this USB drive. If someone tries to forcibly crack it to steal data, it will automatically destroy all the data inside. Of course, you don't have to worry about forgetting your PIN because you can get everything back online, and it also has a backup PIN available for use. However, the price is not low, at $99.
