A fingerprint sensing system for providing data in dependence upon fingerprint information to a computer is disclosed. The system comprises an imaging device for capturing a fingerprint image. The fingerprint image is processed to provide associated data such as a portion of an encryption key. The associated data are secured prior to transmission by encoding into an image frame forming part of a video data signal. The data are encoded at predetermined locations within the image frame instead of image pixel data. The video data signal comprising the associated data are then transmitted to a computer. Upon receipt at the computer the received video data signal is processed to extract the encoded data from the predetermined locations within the image frame.

[ What is claimed is:] [1.] A method of providing data, in dependence upon a fingerprint, to a computer, comprisiing the steps of:providing a fingerprint to an imaging device for providing a digital representation of an image of the fingerprint;using a processor in communication with the imaging device other than a processor of the computer, processing the digital representation of the image of the fingerprint to provide processed data including at least one of data derived from the image of the fingerprint and data retrieved from memory determined in dependence upon the step of processing the digital representation of the fingerprint;securing the data prior to transmission from the imaging device to the computer by the step of: replacing some of the digital representation of the image of the fingerprint with the processed data, the processed data replacing a non-zero portion less than the whole of the digital representation of the image of the fingerprint;transmitting from the imaging device to the computer a video signal comprising the digital representation of the image of the fingerprint including the encoded data therewithin;receiving the video data signal at the computer; and,using the processor of the computer, processing the received video data signal to extract the processed data within one or more fingerprint images, the extracted processed data for use in one of authorising access to the computer and securing of data.
