Abstract: For secure mutual authentication, a customer is authenticated at a first web site. A selection is received from the customer at the first web site requiring transfer to a second web site. An authentication message for the customer is generated at the first web site. The authentication message is devoid of intelligent information of the customer. The authentication message is transferred from the first web site to the second web site for authentication of the customer by the second web site.

Abstract: An apparatus and method for directly imaging fluorophores in tissue or fluid. The apparatus includes a fluorescence exciter light source for generating fluorescence exciter light, a collimater for collimating and directing the light onto the material, and a filter between the material and a camera or the examiner's eye for passing selected wavelengths of light to the camera or to the examiner's eye. The apparatus is useful for detecting leakage in vascular eye tissue, particularly leakage from iris capillaries into surrounding tissues or into the anterior chamber of the eye.
