TL;DR: In this article, the authors present an approach for implementing biometrics-based authentication in a portable device, which includes a microprocessor, a non-volatile memory coupled with a fingerprint authentication module controlled by the microprocessor.

TL;DR: In this article, an authentication system includes a first storage, a ROM and a microcontroller and verifies the password of a host, and upon receiving the password from the host the microcontroller loads and executes the authentication algorithm to verify the password with the hard coded authentication sequence.

TL;DR: A portable data storage device includes a USB controller (2), a master control unit (7) and a NAND flash memory (9) device as discussed by the authors, which uses a memory address mapping table to associate the logical addresses with the physical addresses in the memory device (9), and writes data to or reads data from the physical address corresponding to the logical address.

TL;DR: In this article, an authentication system to verify a password is provided, which includes a first storage unit (16) to store an authentication sequence and a read-only memory unit (18) on which an authentication algorithm (26) is programmed.

TL;DR: In this article, a portable data storage device has a non-volatile memory (3) for storing user data, an interface section (7) for receiving and transmitting data to a host, and a master control unit (1) for transferring data to and from the NVRAM.
