Abstract: A method of providing secure authentication of a service user at a self-service terminal is described. The method comprises: detecting attempted access by the service user to a restricted function on the self-service terminal and ascertaining if a predefined operating system account is present on the terminal. In the event that the predefined operating system account is not present, then the method comprises permitting access to the restricted function by the service user. In the event that the predefined operating system account is present, then the method comprises requesting the service user to provide login credentials and authenticating the login credentials using the operating system account. If the login credentials are not authenticated, access to the restricted function is denied; whereas, if the login credentials are authenticated, access to the restricted function is permitted.

Abstract: A method of determining the Volume Scattering Function of Ocean Waters in the backward direction using a Satellite Ocean Color Sensor the said method made to exploit the geometry of the sun-ocean-satellite detector to function as a backscatter system comprising of the sun [1] as a source of radiation, the ocean as the sampling volume [2], and the satellite ocean color sensor [3] as the detector of the backscattered flux from the ocean emanating from separate ocean pixels arranged on a scan line across the track of the satellite payload and arriving at corresponding pixels on the CCD array detector of the satellite sensor [3]; the output signals from each electronic pixel of the detector is shown to be related to the Volume Scattering Function at a fixed scattering angles (?) which bears a direct relation to the cosines of the solar incident angle (?s) and the angle (?p) of the upwelled flux at the ocean surface, the Remotely Sensed Reflectance (Rrs), and the diffuse attenuation coefficient (Kd) thereby result
