Natural Security standard, based on core specifications, defines a strong authentication method dedicated to online and offline strong authentication. This standard is based on a unique combination of wireless technology, local biometric verification and personal device:
- a personal device stores applications and data used to authenticate the user, resolving problems related to privacy and avoiding the use of biometric databases. The standard can be implemented into various form factors, including smartcard, micro-SD Card, Mobile Phone Secure Element and token.
- wireless communication technology (current IEEE 802.15.4 and Bluetooth Low Energy planned) spares users the need to physically handle this device.
- Biometrics replaces or complements PINs so a transaction can only take place when both the user and the device are present.
This standard defines the architecture and the different components required to enable a transaction based on a wireless acceptance device (WAD) used by a acceptance user (e.g. a merchant) and a wireless personal device (WPD) used by an individual user. The Natural Security standard defines the following core specifications:
- The Natural Security General Description [CORE1 / V 2.3] provides an introduction and a general overview of the Natural Security technology. It also describes services that can be provided by the Natural Security technology.
- The Wireless Personal Device (WPD) [CORE2 / V 2.4] specification describes the device used by the Individual User (e.g. a customer) to execute a WPD session. This document also describes the Personal Access Provider architecture, which is the Natural Security core application residing in any WPD.
- The Wireless Acceptance Device (WAD) [CORE3/ V 2.4] specification describes the device used by the Acceptance User (e.g. a merchant) to execute a WPD session. This document also describes the transaction flow of a WPD session.
- The Wireless Personal Area Network (WPAN) [CORE4/ V 4.01] specification describes a mid-range wireless communication protocol used to connect the WPD with the WAD. This protocol based on WPAN is defined by Natural Security.
- The Wireless Biometric Intelligent Reader (WBIR) Protocol [CORE5 / v2-43] specification provides the functional description of a device integrating the main Natural Security components, thus simplifying the integration of the Natural Security solution in existing systems. This document also describes the protocol messages to be used by a “Controlling-Device”, such as a POS or a PC, to control a WBIR.
