There are plenty of ways to protect data inside a flash drive, like using a special software, a password, or some kind of encryption method, but the most original idea is to use a lock.

On top of previously mentioned feature, it can also be used to lock other gadgets that have a USB interface, like a mouse, keyboard, memory card reader, etc. As long as the jack connector measures 4mm of thickness and 11.5mm in length, it is all good.

The locking combination consists of 3 numbers, and to reset the combo you just need to press a small button with a needle, that is, when the lock is open.

Insert USB male jack with the indented metal side up and change the numbers to lock the USB device.

The USB Dial Lock is priced at $11 and available online.
