Abstract: Systems and methods scan a previously printed sheet using a scanner to create an original scan, and evaluate the original scan to identify marks printed on the printed sheet. For example, any marks, such as the straight and curved marks located in separation areas (areas separating data areas of the printed sheet) of the printed sheet can be evaluated using a specialized image processor. Then, these systems and methods alter the pixels of such marks to add security features (e.g., microtext, microprinting, etc.) to the marks that identify the time, place, and user of the scanner, and this process produces an altered scan. Rather than outputting the original scan, these systems and methods instead substitute the altered scan in place of the original scan and, therefore, output the altered scan from the image processor in place of the original scan.

Abstract: A method of creating a confidence map for an electronic fillable form may include identifying, by an electronic device, one or more fillable fields of an electronic fillable form. The method may include, for one or more of the identified fillable fields, assigning one or more first coordinates of the electronic fillable form to define a graphical zone associated with the fillable field, assigning one or more second coordinates of the electronic fillable form to define a fill zone, assigning one or more third coordinates of the electronic fillable form to define a click zone, and assigning, by the electronic device, one or more fourth coordinates of the electronic fillable form to define a start zone representing a most likely selection area for the fillable field. The method may include creating, a confidence map associated with the electronic fillable form.

Abstract: A system of identifying one or more fillable fields of an electronic form may include an electronic device, and a computer-readable storage medium that includes one or more programming instructions. The programming instructions are configured to instruct the electronic device to receive an electronic form, identify fillable field candidates of the electronic form, and determine, for each fillable field candidate, whether the fillable field candidate is a fillable field. The system updates metadata associated with the electronic form by applying a sequencing framework to only the fillable fields by obtaining position information for each fillable field that indicates a position of the fillable field on the document, sorting the fillable fields based on the position information to form a sequence of fillable fields, determining a designator to each fillable field that indicates a position of a corresponding fillable field in the sequence, and storing the designator.

Abstract: An image is received that contains handwritten characters as answers to an inquiry. An automatic character recognition process is performed on the image to generate initially recognized characters from the handwritten characters. The initially recognized characters of an incorrect answer to a question of the inquiry are analyzed to automatically identify alternative recognized characters of the incorrect answer. Then, it can be determined whether one or more of the alternative recognized characters, when substituted in place of the initially recognized characters of the incorrect answer, change the incorrect answer to a correct answer to the question. If the alternative recognized characters substituted in place of the initially recognized characters in the correct answer exceed a minimum character recognition confidence value, the incorrect answer is changed to the correct answer to modify the initially scored answers to modified scored answers, and such are output.

Abstract: A device for registration of content in a filled-out application form is disclosed. The device is configured for scanning at least one portion of the filled-out application form. The device is configured for extracting filled-out content from the scanned form. The geometrical features of the master form are retrieved. The master form includes one or more anchor fields. Each anchor field has one or more anchor zones and at least one anchor segment. At least one anchor segment has global adjustment parameters and geometrical features. The extracted filled-out content is related to the retrieved geometrical features of a master form to create a new geometrical representation of the extracted filled-out content of the scanned application form. The new representation of the filled-out content based on the global adjustment parameters for the at least one anchor segment is globally adjusted. The globally adjusted filled-out content based on the geometrical features for the anchor segments is locally adjusted.
