    • The apparatus (40) has a sensor (41) disposed on the first end (42) of an elongate connector (43) by means of fixed interface link (79). A recorder unit (44) is disposed on the second end (45) of the connector (43) opposite the first end (42). The connector (43) is bendable within a predefined curvature range. When the apparatus (40) is deployed into the sea, it is adapted to free-fall through the body of water and to land on the seafloor such that the sensor (41) is spaced apart from the recorder unit (44). The length of the connector (43) is dynamically variable within a predefined range so as to eradicate or minimise coupling of any vibration of the recorder unit (44) to the sensor (41). The physical separation of the sensor (41) and the recorder unit (44), together with the mechanical characteristics of the connector (43), ensure that the sensor (41) is substantially vibrationally de-coupled from the recorder unit (44). In other words, the mass of the recorder unit (44) does not inhibit the sensor (41) from responding to seismic waves, and any vibration of the recorder unit (44) (for example due to any water currents that may be flowing in the vicinity of the recorder unit (44) ) is not substantially transmitted to the sensor (41). Hence, the connector (43) constitutes a positive mechanical connection between the sensor (41) and the recorder unit (44) so far as maximum separation distance is concerned, however not so far as seismic or flow induced vibrations are concerned.

    • The most preferred method of augmenting an existing token-based identification system is to splice into a data stream transmitted from a token reader to a control panel such that an acquired token factor from a user is intercepted by a biometric identification, or authentication, system that is wedged in series at a splice in the data stream. When the token reader transmits a data stream, such as a Wiegand interface, to the control panel, the data stream is used by the biometric identification system to prompt the user to present an anatomical feature to a biometric reader. The biometric reader creates a biometric inquiry template that is transmitted to a biometric search engine, along with the acquired token factor, such as a PIN or barcode, to perform data match analysis against one or more enrollment templates associated with the acquired token factor. The search engine will either match an authorized user or reject an unidentifiable user. If there is a match, then the data stream is allowed to pass from the biometric reader to the control panel of the existing token-based identification system. The existing system does not otherwise need to be modified. The security of an Access Control System (ACS) can be greatly enhanced by this method of augmentation that, preferably, wedges an automatic fingerprint identification system (AFIS) into the data stream of an established ACS.
