We often store important and confidential files in pen drives or flash storage devices for transferring/sharing data. Although convenient, there remains a concern regarding misplacing these storage devices that can go into wrong hands and create problems, so we need special storage devices, which we can securely save and share our files. There is several software available in the market that allow us to encrypt and lock our files but they require a certain ‘know-how’ for installation in the laptops and PCs, which will be used with the flash drive. Also available are some flash devices that work on fingerprint or password authentication. However, these require installation of special drivers in a PC and only support Windows 10 or 8 but not Linux. Therefore, we have decided to make a smart flash storage device that is based on fingerprint authentication and works without installing any software or drivers in a PC. Using Bluetooth serial terminals, a user’s fingerprint or password authentication is done via an app on a phone. This concept project can be used for developing a reliable smart flash storage solution.
