Method for identity verification

The method for identity verification employs biometric technology. Positioned at the center of the system is a stylus with any of a number of biometric properties or their combination or with one or more metric sensors, while the customer uses the stylus to sign his / her name, or even for writing anything. The identity verification system is used at point-of-sale terminals, in various closed environments, to access a computer network, in applications involving pen-based computers and smart-pens, and for e-commerce. When fingerprint sensors are used, the sensors are positioned in the stylus grip, one sensor for the index finger, and a second sensor for the thumb. In one variation, one-to-one biometric matching is used. Each participant carries on his / her person a device that includes an encrypted biometric for reference purposes to gain access Into the system. Processing is simplified since the system need only make a “MATCH” or “NO MATCH” decision. In a second variation that is particularly useful in closed environments, one-to-many biometric matching is used. During each event access request, the community of reference prints is searched for a match with the applicant. Each member of the community need carry nothing on his / her person to participate in the system. In either variation, the stylus is either attached to each site or is portable, one such stylus being carried by each participant.

Three-dimensional human body gait quantitative analysis system and method

The invention discloses a three-dimensional human body gait quantitative analysis system and method. The method comprises the following steps of: simultaneously using two inertia measurement nodes on feet, carrying out analyses fusion on the data of the two inertia measurement nodes, measuring a more accurate gait parameter, and obtaining information which can not be measured in a single-foot manner; and firstly storing the collected data in storage units of the measurement nodes in a walking process, and finally transmitting the collected data to an analytical calculation device in a wired or wireless manner after the walking process is ended. The high-speed acquisition of all gait information in the walking process can be realized and no characteristic gait information point is omitted. A foot part binding device of the designed inertia measurement node is adopted, a measuring error brought by fixed position shift of the measurement nodes in the walking process is eliminated, and the identity of fixed positions of the measurement nodes in a walking process is guaranteed through repeated measurement; and a gait analytical calculation program module adopts a moving window searching value method to definition a characteristic point of gait information, and can more exactly extract the gait diagnostic information.
