Therefore, this paper presents a secure USB mechanism that prevents leakages of authentication data and does not compare authentication data for smart human care services, which have been a fundamental problem of existing flash drives. As such, there is growing demand for a more powerful secure USB flash drive to solve these fundamental problems. However, it has been continuously reported that the secure USB flash drive, which protects data through the adoption of a wide range of security technologies in wide-ranging ways, cannot assure data security because of implementation and environmental vulnerabilities, eavesdropping, unlock commands, and reverse engineering. The secure USB flash drive was developed to improve the security of the conventional USB flash drive, which is vulnerable to leakages of internally stored data caused by extortion, loss, etc.
