Abstract: A system and method for using imprinting as part of a security function that involves a user, for a security and/or identification mechanism. Imprinting is preferably used for cryptographic primitives, for determining a one-way function that operates at least partially according to a characteristic and/or function of the human brain.

Abstract: An image capturing system and method for automatically watermarking a plurality of recorded camera and image parameters such as the location (latitude, longitude and altitude), orientation of the principal axis of the camera, whether the camera is in landscape mode or portrait mode, camera velocity, photographer information, time and date, zoom factor, shutter speed, flash on/off, autofocus distance, lightmeter reading, focal length and aperture into every captured image. This watermarked data can be subsequently extracted and compared with the originally recorded data so as to verify the authenticity of a corresponding image. Since the critical data is invisibly watermarked into the image, it is difficult to modify the image without affecting the watermarked data.

Abstract: System and methods for querying digital image archives containing digital photographs and/or videos (collectively, “digital images”). The digital images are indexed in accordance with a plurality of recorded parameters including time, date and geographic location data (altitude and longitude), as well as image data such as lens focal length, auto focus distance, shutter speed, exposure duration, aperture setting, frame number, image quality, flash status and light meter readings, which are used for searching a database consisting of the digital images. These images are preferably generated by an image capturing system which is capable of measuring and recording a plurality of parameters with each captured digital image. The image retrieval system allows a querying user to search the image archive by formulating one or more of a plurality of query types which are based on the recorded parameters, and then retrieve and display those images having the specified parameters.

Abstract: A computer system is described including a camera, a display device (e.g., a display monitor) having a display screen, and a processing system coupled to the camera and the display device. The camera produces image signals representing one or more images of an object under the control of a user. The processing system receives the image signals, and uses the image signals to determine a state of the object. The state of the object may be, for example, a position of the object, an orientation of the object, or motion of the object. Dependent upon the state of the object, the processing system controls cursor movement and selection of a selectable item at a current cursor location. The object may be a body part of the user, such as a face, a hand, or a foot. The object may also be a prominent feature of a body part, such as a nose, a corner of a mouth, a corner of an eye, a finger, a knuckle, or a toe. The object may also be an object held by, attached to, or worn by the user.
