BDS™ Sensor ASIC
IDesia’s IBA200 BDS™ Sensor ASIC is a custom-designed integrated circuit enabling manufacturers and system integrators to seamlessly incorporate BDS™ authentication technology into their biometric systems.
This small form factor, low power, modestly priced chip is designed to easily fit inside small portable devices, such as mobile phones, laptops and USB tokens, with the BDS™ engine running on the target device’s microprocessor.
The IBA200 BDS™ ASIC is housed in a compact QFN32 package that is less than
one-third the size of existing fingerprint chipsets. The first ASIC generation measures 5 x 5 x 0.8 mm, compared to a typical fingerprint chipset's 15 x 5 x 2 mm.
IDesia's sensor architecture comprises two key elements: small footprint conductive contact points (made of metal or coated plastic) integrated onto the surface of the target device, and a sensor ASIC. The sensor ASIC features a serial communication interface (UART) and utilizes high performance low noise amplifiers, numerous filtering and signal conditioning stages and an A/D converter to perform high quality acquisition of the electrophysiological signals of the person touching the contact points. It also contains circuitry for automatic detection of users touching the sensors, and power management logic that keeps power consumption down in standby mode.
Future Roadmap
BDS200™ ProSensor Chipset
Aimed at device manufacturers and systems integrators, IDesia's BDS200™ ProSensor Chipset will be implemented as a combined ASIC incorporating both acquisition sensor and processing hardware for verification of users' identity.
The BDS200 ProSensor Chipset will enable incorporation of BDS™ technology in high security preboot applications and in devices not equipped with microprocessors of their own.
This advanced chipset will be particularly suitable for a broad range of high-end security applications requiring completely separate biometric modules, such as standalone panels for access control and electronic locks for safes and cars.
The BDS200 ProSensor Chipset's enhanced optional features include a "challenge response" mechanism ensuring virtual real-time authentication and preventing any potential spoofing. "Challenge response" is of utmost importance for m-commerce and other Internet services.
