Patent number: 7406599Abstract: Methods and apparatus, including computer program products, for presenting status of digital signatures. A digital document is received that defines a presentation structure and includes a digital signature. The digital document specifies a representation of the digital signature and a location in the presentation structure for the representation of the digital signature. A status is determined for the digital signature. A status representation is associated with the digital signature, where the status representation identifies the status determined for the digital signature. Without altering the representation of the digital signature, at least a portion of the digital document and the status representation of the digital signature are presented in a user interface, where the status representation is presented in the presentation structure at a location that depends upon the location of the digital signature.Type: GrantFiled: April 6, 2004Date of Patent: July 29, 2008Assignee: Adobe Systems IncorporatedInventors: James D.

Publication number: 20080152202Abstract: The invention refers to a computer-based system for the acquisition, analysis, and authentication of the handwritten signature. The person that performs a handwritten signature performs a series of three-dimensional movements with a plane graphical finality. The movements generate kinetic information perceived by the special pen that the signature is performed with (the writing and digital acquisition device for the primary bio-kinetic information). The information, concordant to the afferent bio-kinetic pattern, is collected by the included MEMS type acceleration sensors in the pen. The system continues to analyze the generated information (the signals) and it determines the dynamic-biometrical characteristics, based upon the biometrical dimension of the information. The characteristics are transformed in data vectors and invariants that are stored in a database.Type: ApplicationFiled: February 1, 2006Publication date: June 26, 2008Inventors: Gabriel Alexandru Moise, Marian Secrieru, Adrian Dinescu, Stefan Stelian Diaconescu

Publication number: 20080059076Abstract: A method for classifying a plant leaf by utilizing the feature points of venation has been developed. A sample image of the venation can be extracted by utilizing a Curvature Scale Space (CSS) Corner Detection Algorithm.

Patent number: 5802200Abstract: In a method for determining a reference autograph character string on the basis of a set of sample autograph character strings from the same writer, a particularly characteristic autograph character string can be selected from a set of produced sample autograph character strings, e.g. signatures. In signature verification, such references are needed to serve as a comparison measure in the identification of the signer. The method according to the invention divides the produced character strings of a sample set of signatures into strokes according to the execution, and compares individual strokes with respect to the recorded dynamic parameters, such as for example pressure and locus coordinates and writing speed, in order to enable the determination of the deviation of all the strokes of the sample character strings from one another.Type: GrantFiled: March 12, 1996Date of Patent: September 1, 1998Assignee: Siemens AktiengesellschaftInventor: Brigitte Wirtz

Patent number: 5730602Abstract: A computerized system for teaching handwriting skills to a student displays a character to be written, prompting the student to use a digitizing pen to write the character on a digitizing surface, operating the digitizer to capture pen tilt angle, x,y coordinate values, pen tip pressure, pen tip height, and timing for each pixel. These pen stroke parameters and parameters computed therefrom, including pen tilt direction, are compared with stored corresponding "ideal" or "normal" data and the results of such comparisons are analyzed to determine whether a handwriting "process problem" exists. If so, appropriate "on the spot" corrective feedback information is generated and delivered in audible and/or visual form to the student at the times it will be most beneficial.Type: GrantFiled: April 28, 1995Date of Patent: March 24, 1998Assignee: Penmanship, Inc.Inventors: Harry S.

Patent number: 5604817Abstract: A method for the optical three dimensional measurement of a tooth without calibration bodies. An optical projection system projects a pattern onto a tooth, and an optical imaging system images the pattern projected thereon, from a first position in space and subsequently from a second position in space, with the images from the two positions in space having a common imaged area of the tooth. The image patterns are evaluated to calculate three dimensional coordinate data of the tooth surface relative to the respective imaging position for each image and also for the two images combined, to produce a single three dimensional tooth surface data record. In this method, points and/or surfaces are selected from the common imaged area with the aid of properties of the tooth surface contour which are invariant under displacement and rotation, so that they can be clearly correlated with each other.Type: GrantFiled: August 18, 1993Date of Patent: February 18, 1997Assignee: Kaltenbach & Voigt GmbH & Co.Inventors: Robert Massen, Christian Konz, Joachim Gassler, Harald Richter
