    Abstract: A system is provided for authenticating a user's signature as electronically inputted into the system by a mouse or other manual input device. The system extracts angle and distance data relating different parts of the user's signature and stores corresponding data relating to a reference signature captured during a training procedure. The extracted data is then compared with the reference data to provide a basis for authentication. Such a system provides an on-line dynamic biometric verification system that can be customized to multiple Internet based applications requiring secure authentication.

    Abstract translation: 提供了一种系统，用于通过鼠标或其他手动输入设备电子地输入到系统中来认证用户的签名。 该系统提取与用户签名的不同部分相关的角度和距离数据，并且存储与训练过程中捕获的参考签名有关的相应数据。 然后将提取的数据与参考数据进行比较，以提供认证的基础。 这样的系统提供在线动态生物特征验证系统，其可以被定制到需要安全认证的多个基于因特网的应用。

    Abstract: A sensor grid system (10), and a method of operating a sensor grid system, having a first array of inductors (14a) and a second array of inductors (14b). The first and the second arrays are each responsive to a moveable coil (18) that transmits an electromagnetic signal for having adetectable signal induced therein. The method includes a first step of determining an expected position of the coil relative to an array of inductors. A next step selects a pair of inductors that are located near to the expected position. A third step measures the signals induced into the pair of inductors, and a fourth step, based on the measurement step, determines any additionalinductors from which measurements are required to interpolate the actual position of the coil. A fifth step measures the signals induced into the determined ones of the additional inductors, and a sixth step computes and reports the actual position of the coil based on the results of the first and the second steps of measuring. Significantly, the pair of inductors and the additional inductors include all inductors that are required to compute the actual position of the coil, and includes no inductors that are not required to compute the actual position of the coil.
