At the heart of Biolog Device´s highly secure fingerprint USB is Hyperstone´s U9 flash memory controller. Biolog Device has chosen Hyperstone´s controller and API to support the BFU100A´s design due to their renowned reliability and flexibility in enabling customer firmware extensions.
The high performance features of the U9 Flash Memory Controller coupled with Hyperstone’s API (Application Programming Interface) have allowed Biolog Devices’ design to become a truly unique USB stick. It can be used across a range of embedded storage applications where security precautions are a must.
Hyperstone’s API permits the addition of proprietary firmware extensions to the existing firmware. This enabled Biolog Device to integrate their proprietary fingerprint sensor, thus enabling extra authentication and encryption to further protect data as it is passed through the controller onto the flash. Hyperstone´s U9 is employed to manage the flow of both biometric and user data stored inside the USB stick. The firmware extensions developed by Biolog Device using Hyperstone’s API ensure the fast recognition speed of fingerprints, while retaining excellent read and write performance of data to and from the flash memory.
Biolog Device´s BFU100A is fully compliant with USB 3.1 and boasts SuperSpeed performances guaranteeing maximum performance with secure data processing. Hyperstone´s U9 controller also offers a comprehensive compatibility across a wide range of NAND flash memories. In this instance, Biolog Device has chosen a MLC flash to safely store data.
Due to its low power-consumption, meticulous encryption software and capacity to efficiently store multiple authentication codes, the BFU100A is ideally suited for applications where secure data storage is imperative.
