ACE CAD ACECAT 302 DRIVER
The test features may be compared against features of a set of template signatures, and verified in response to the presence or absence of the test features in the template signatures. The test signature may be preprocessed, so as to normalize it and remove artifacts which are irrelevant to verification.
The features of the template signatures may Ace Cad Acecat 302 determined and stored in an associative memory or a data structure with associative memory capabilities, e. The method of verification may be adjusted to greater or lesser sensitivity in response to external conditions. Field of the Invention This invention relates to signature verification. Description of Related Art In a variety of applications, methods for verifying that a Ace Cad Acecat 302 seeking access is in fact authorized are often required.
For example, keys are commonly used to Ace Cad Acecat 302 some form of authentication before entry to a building or a vehicle is permitted. Where access is desired to software programs or to software-controlled devices such as an automated bank teller or credit card account access is often verified by requiring that the person seeking access enter a password or personal identifier number "PIN"or by requiring that such information be recorded on a magnetic strip or in the memory of a "smart" card. While these methods of the prior art achieve the goal of limiting access, they are subject to several drawbacks. It would be advantageous to have a method of Ace Cad Acecat 302 which allows verification in response to the signature of the person seeking access.
However, known methods of signature matching generally require costly human review of the signature. Accordingly, it is an object of the invention to provide a method of automated signature verification.
In a preferred embodiment, the test signature may be preprocessed, so as to normalize it and remove artifacts which are irrelevant to verification. In a preferred embodiment, the features Ace Cad Acecat 302 the template signatures may be determined and stored in an associative memory or a data structure with associative memory capabilities, e. In a preferred embodiment, the method of verification may be adjusted to greater or lesser sensitivity in response to external conditions.
An automated signature verification system may comprise an input device for receipt of an input signaturesuch as a writing implement and a pressure platecoupled to a processor for receiving data relating to the input signature In a preferred embodiment, the writing implement and pressure plate may comprise Ace Cad Acecat 302 stylus and graphics tablet for freehand computer input, in which the location of the stylus on the tablet and the pressure then exerted are periodically transmitted to the processoras are known in the art such as the "Acecat" graphics tablet made by ACECAD of Monterey, Calif. However, it would be clear to those skilled in the art, after perusal of this application, that other types of input device would also be workable, and are within the scope and spirit of the invention.
The operation and software structures of this system are described herein in terms of their functions and at a level of detail which would be clear to those of Ace Cad Acecat 302 skill in the art. It would also be clear to those skilled in the art, after perusal of this application, that processors of other types could be adapted to methods shown herein without undue experimentation, and that such other types of processor are within the scope and spirit of the invention.
In response to the input signaturethe processor may generate a verification signalwhich may be Ace Cad Acecat 302 to verify the identity of the Ace Cad Acecat 302 writing the input signature This verification signal may be viewed by an operator, may be coupled directly to a locking deviceor may be coupled to software within the processor or within another processor. In a preferred embodiment, the verification signal may be combined with other methods for verifying the identity of the person, such as methods which are already known in the art.

A method of automated signature verification may comprise a template input stepa template normalization stepa template storage stepa test input stepa test normalization stepa comparison stepand an accept-reject decision step As shown herein, the method may use a system as described with reference to FIG. In a preferred embodiment, the set of template Ace Cad Acecat 302 may comprise at least five individual signatures. These template signatures are each input and normalized, and stored for later comparison.

The method may then Ace Cad Acecat 302, when verification of a person's identity is desired, to verify a test signature. The test signature is input and normalized, compared with the template signatures, and accepted or rejected in response to that comparison.

In the template input stepthe person whose identity is to be verified later may write a set of template input signatures on the input devicee. The template input signatures are known to be valid signatures, Ace Cad Acecat 302 may be used later for comparison with the test input signature At the template input stepthe identity of the person may be explicitly identified to the system, e. However, it is not required that the identity of the person be explicitly identified, e. Official Ace Cad Acecat Free Driver Download for DOS - .
