SYSTEM AND METHOD OF AUTHENTICATION OF AN ELECTRONIC SIGNATURE

摘要

A system and method supporting signature verification. An input signature from a contact point of a stylus at a touch-sensitive surface is received. At least one sensor detects a first set of characteristics of the input signature that represents how the stylus is used when a present security level is a first level, and a second set of characteristics is determined when a present security level is a second security level. The second set of characteristics is a subset of the first set with fewer characteristics than the first set. One of the first set of characteristics or the second set of characteristics is transmitted to a characteristic receiving device to permit the input signature to be authenticated as a function, at least in part, of the first set or the second set of characteristics.

主权项

1. A method, comprising:
receiving an input signature from a contact point of a stylus at a touch-sensitive surface of an input receiving device as the stylus is used to sign a user's name; detecting, based on a present security level being a first security level, a first set of characteristics of the input signature by at least one sensor that represents how the stylus is used to sign the user's name; detecting, based on the present security level being a second security level, a second set of characteristics of the input signature by at least one sensor that represents how the stylus is used to sign the user's name, the second set of characteristics being a subset of the first set comprising fewer characteristics than the first set; and transmitting one of the first set of characteristics or the second set of characteristics to a characteristic receiving device to permit the input signature to be authenticated as a function, at least in part, of the first set or the second set of characteristics.
