  • Patent number: 7860846
    Abstract: An assigning unit included in a device assigns an ID to a verification-target character string. A mapping file creating unit creates a mapping file in which the ID is associated with location data that indicates a location of the verification-target character string. In addition, an encoding unit included in the device encodes the ID into a zero-width character string. A character-string concatenating unit concatenates the zero-width character string to the verification-target character string. Furthermore, a decoding unit included in the device decodes the zero-width character string to the ID in response to selection of the verification-target character string displayed by a verification-target character string output unit. An extracting unit extracts the location data from the mapping file on the basis of the decoded ID. A mapping data output unit included in the device displays the mapping data including the extracted location data.
