The present invention relates to improved ophthalmic diagnostic measurement or treatment methods or devices, that make use of a combination of a high speed eye tracking device, measuring fast translation or saccadic motion of the eye, and an eye position measurement device, determining multiple dimensions of eye position or other components of eye, relative to an ophthalmic diagnostic or treatment instrument.

A security server qualifies the execution of programs for networked host computer systems using a database storing pre-qualified program signatures and defined policy rules associating execution permission qualifiers with execution control values. The server executes a control program in response to execution requests received via a communications network interface from identifiable hosts, wherein a predetermined execution request received from a predetermined host computer system includes an identification of a program load request, request context related data, and a secure program signature. The control program determines an execution control value based on an evaluation of the execution request relative to the pre-qualified program signatures and defined policy rules. The execution control value is then returned to the predetermined host computer system to securely qualify the execution of the program identified from the program load request.

An identification card includes a fingerprint sensor, an antenna, a dual-mode radio frequency modulator connected to the antenna and digital circuitry having memory to store a digital word, the digital word including a representation of a fingerprint initially scanned by the fingerprint sensor to identify an individual associated with the identification card. The identification card further includes a control processor connected to the digital circuitry and the radio frequency modulator to communicate a signal to the antenna indicative of a successful match between the fingerprint initially scanned by the fingerprint sensor and newly scanned fingerprint. With such an arrangement, a technique is provided biometrically authenticating the identity of an individual passing through a checkpoint without requiring the individual to stop or exit a vehicle and eliminates the need for a central database of biometric data on individuals.

A method for safeguarding an electronic document includes inserting at least one digital signature image into the electronic document and generating a first check sum for the electronic document, with or without optionally-inserted biometric signature data, using a first hash function. A second check sum is then generated using a second hash function. The first check sum and the biometric data, if provided, are then symmetrically encrypted using a key that is the sum of the second check sum and a generated random value. The symmetrically-encrypted first check sum is attached to the document. The random value is then asymmetrically encrypted using a first public key of a first key pair and the asymmetrically-encrypted random value is added to the document.
