Virtually fraud-proof authentication for wireless mobile financial transactions. A mobile telephone, genius card or dongle may capture multiple biometrics, such as fingerprint, voiceprint, retinal recognition data, facial biometric data, ear biometric data and bio print, iris scanning data, pupil movement recognition data, and send segments of each of them to a server computer that re-constitutes them and stores them for matching during an attempted financial transaction. A purchasing individual has multiple biometrics read by separate readers integrated into a single hand-held device. An automatic process of the server computer has previously sent a command packet to the hand-held device defining percentage and portion of each biometric to select and the sequence and channel of transmission for matching along with other out of band security data. During the charging phase, the hand-held device may utilize a slidable antenna for swiping a magnetic strip of a charge card reader or may display credit card data for a limited amount of time.

The image-based system is used to observe and document eye responses which can be used to implement the procedures defined in the Standardized Field Sobriety Test as well as the Drug Recognition Expert Program. These eye responses include pupil movement, as well as pupil size and responses, for either one or both eyes simultaneously. The system includes a headset against which the subject places their face. The faceplate has an opening through which illumination devices transmit beams of infrared light to illuminate the subject's eyes. A reflective protractor, having a scale imprinted thereon, is mounted on the headset above the eye opening and facing the test administrator to provide an image of the stimulus target that is used by the test administrator. Two imaging devices are mounted on the headset opposite the eye opening to generate images of the subject's illuminated eyes. The generated images are transmitted to an image recording device for storage and an image display device for display to a test administrator.

A method of 3D morphing driven by facial tracking is provided. First, a 3D model is loaded. After that, facial feature control points and boundary control points are picked up respectively. A configure file “A.config” including the facial feature control points and boundary control points data that are picked up corresponding to the 3D avatar is saved. Facial tracking algorithm is started, and then “A.config” is loaded. After that, controlled morphing of a 3D avatar by facial tracking based on “A.config” is performed in real time by a deformation method having control points. Meanwhile, teeth and tongue tracking of the real-time face image, and scaling, translation and rotation of the real-time 3D avatar image is also provided. In addition, a control point reassignment and reconfiguration method, and a pupil movement detection method is also provided in the method of 3D morphing driven by facial tracking.

The impairment determination system automatically determines impairment of a subject based on pupil movement, as well as pupil responses to illumination and target tracking for either eye or both eyes simultaneously. The impairment determination system automatically processes a series of digital image frames, taken during the execution of a predetermined test protocol, to determine pupil location, size, and responsiveness to changes in illumination, which data are used by the impairment determination system to determine impairment of the subject. The present impairment determination system uses a method for quickly and accurately localizing the subject's pupils, as well as their boundaries, area, and center coordinates, which data is used as part of the impairment determination process.

The invention discloses a terminal and a remote control method thereof. The method comprises the steps as follows: at least two frames of images of a user in a set area are acquired, and face positioning of the images is performed; according to double-eye reference positions which are established in advance, pupil positioning of the face images is performed, and the movement conditions of pupils are determined according to positions of the pupils; remote control instructions corresponding to the movement conditions of the pupils are looked up and executed from operation strategies, so that corresponding operation functions are realized; and a process for establishing the double-eye reference positions is as follows: a double-eye opening image and a double-eye closing image of the user in the set area are acquired, and the double-eye reference positions are established according to the difference of vertical gray-level projection histograms of the double-eye opening image and the double-eye closing image. Compared with a conventional pupil tracking technology, the terminal and the method improve the pupil positioning accuracy; the problem that in a process that the terminal is controlled remotely through the pupil movement, the pupils are not positioned accurately, so that the terminal identifies the pupil movement mistakenly is solved; and misoperation, caused by identification errors, of the terminal is reduced; and an experience effect of the user is improved.

The invention relates to a visual field detection method and system based on head-mounted detection equipment and a detection device. The method comprises steps as follows: the detection device located in an electronic device sends a starting notification used for starting monitoring of movement loci of the pupil of a current to-be-detected eye to an eye movement tracking system after receiving a test starting instruction sent by a controller; the detection device receives pupil movement state information sent by the eye movement tracking system; the detection device determines the pupil movement loci according to the movement state information, wherein the controller is a part which is associated with the head-mounted detection equipment and in communication connection with the detection device of the electronic device. With the adoption of the method, the detection complexity can be reduced, and the detection accuracy and comfort can be improved.
