Abstract
The invention relates to the authentication of users for a multi-function peripheral (MFP) device using handwritten signatures. Systems and methods are disclosed which relate to a MFP that conditions access to MFP operations based on an authenticating process that compares a prospective user's signature to previously saved signatures. The signatures are communicated to the MFP using the MFP's native scanning function.
Claims26
A method of authentication services for a multi-function peripheral (MFP) device, the method comprising:
- printing an authentication signature form for receiving a reference handwritten signature;
- scanning the reference handwritten signature from the authentication signature form with the MFP as part of a reference information for authentication;
- receiving an authenticating handwritten signature on top of an unique image on another authentication signature form, the unique image dynamically generated in the MFP;
- comparing the authenticating handwritten signature with the reference handwritten signature and the unique image on the another authentication signature form with the unique image in the MFP;
- and
- permitting access to the MFP based, at least in part, on the comparison,
- wherein the MFP is an integrated peripheral device configured to perform two or more functions, and wherein the functions include scanning and printing.
4 more elements
A multi-function peripheral (MFP) system with handwritten signature authentication, the system comprising:
- means for printing an authentication signature form for receiving a reference handwritten signature;
- means for scanning the reference handwritten signature from the authentication signature form with the MFP as part of a reference information for authentication;
- means for receiving an authenticating handwritten signature on top of an unique image on another authentication signature form, the unique image dynamically generated in the MFP;
- signature;
- means for comparing the authenticating handwritten signature with the reference handwritten signature and the unique image on the another authentication signature form with the unique image dynamically generated in the MFP;
- and
- means for permitting access to the MFP based, at least in part, on the comparison,
- wherein the MFP is configurable as both a stand alone peripheral device and a networked peripheral device configured to perform two or more integrated functions, and wherein at least one of the functions includes scanning, copying, printing, or faxing.
5 more elements
A method of representing handwritten signatures as a calculated composite, the method comprising:
- capturing an image of a signature reference form having dynamically generated unique images, wherein the signature reference form comprises a plurality of handwritten signatures on top of the unique images;
- extracting digital representations of the at least two handwritten signatures on top of the unique images from the image;
- and
- storing the digital representations as a calculated composite,
- wherein the method is performed in a multi-function peripheral (MFP) device configurable as a stand alone peripheral device configured to perform two or more integrated functions, and wherein at least one of the functions includes scanning, copying, printing, or faxing.
2 more elements
A multi-function peripheral (MFP) system with handwritten signature authentication, the system comprising:
- an MFP, the MFP having integrated functions of scanning and printing for an authentication signature form for receiving a reference handwritten signature, and further equipped to communicate with an authentication module;
- an authentication database, the authentication database comprising at least one digital representation of at least one reference handwritten signature;
- and
- an authentication module, the authentication module configured to receive an image of at least one authenticating handwritten signature on top at least one unique image, dynamically generated in the MFP captured by the scanning function of the MFP in a communication from the MFP, further configured to compare the at least one authenticating handwritten signature with the at least one digital representation of the at least one reference handwritten signature and the at least one of the unique image in the MFP and further configured to communicate an authenticating message to the MFP.
1 more element
A multi-function peripheral (MFP) device with handwritten signature authentication, the device comprising:
- an MFP, having two or more integrated functions including a scanning function and a printing function, the MFP having an integrated printer to print an authentication signature form having a unique image, dynamically generated in the MFP for receiving a reference handwritten signature, the MFP having an integrated optical scanner configured to capture an image of the reference handwritten signature on top of the unique image from the authentication signature form for authentication, wherein the MFP is configured to communicate at least one scanned image of at least one handwritten signature on top of at least one unique image dynamically generated in the MFP to an authentication module, and wherein the MFP is configured to condition access to the operations of the MFP based on an authenticating communication from the authentication module.
A method of authentication services for a multi-function peripheral (MFP) device, the method comprising:
- storing reference information associated with a personal credential of an authorized user;
- receiving an authenticating personal credential on top of an unique image dynamically generated in the MFP from a prospective user of an MFP via an integrated scanning function of the MFP;
- comparing the authenticating personal credential and the unique image with the reference information and the unique image in the MFP;
- and
- permitting access to the integrated scanning function and at least one additional integrated function of the MFP based, at least in part, on the comparison.
