Abstract: The present disclosure includes, among other things, systems, methods and program products for delivering data over a computer network.

Abstract: A system produces certified content by receiving original content acquired from a content acquisition device and receiving a device identity associated with the content acquisition device. The system produces a certification value indicating the original content was acquired from the content acquisition device having the device identity. The system associates the certification value to the original content to produce certified content that can be verified to represent the original content that was acquired from a content acquisition device having the associated device identity while preventing modification to the original content by processing not associated with certification processing. This process is performed in an uninterrupted manner to ensure certified content reflects an accurate device identity. The system can be implemented entirely within a content acquisition device itself, or in a computer system coupled to a content acquisition device.

Abstract: Methods and apparatus, including computer systems and program products, for enabling the use of machine-readable codes. A computer program receives data generated by reading a machine-readable code and detects the presence of formatting information indicating whether the data's payload is in a first or second format. The program uses a first or second procedure to decode the payload depending on whether the formatting information is detected and what it specifies. In some embodiments, the formatting information can include information about how to decode the payload. The machine-readable code can have been produced according to an encoding instruction associated with an electronic document. The first and second formats can be open and closed formats, respectively. The use of multiple formats can enable multiple, co-existing business models in a document workflow, whereby different parties in the workflow can be charged or required to obtain authorization for the use of machine-readable codes.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for generating a form and extracting user data from a form, the form including one or more data fields. Zoning information and structural information about the data fields are defined and encoded according to a symbology defined by rules for encoding information in a medium in which the form will be presented. The encoded zoning and structural information is incorporated in a representation of the form to be presented in the medium. Data entered on the form by a user can be extracted based on the encoded zoning and structural information.

Abstract: Methods and apparatus, including computer systems and program products, for creating and using documents with machine-readable codes. A computer program receives user data provided for one or more fields in an electronic document, generates input data containing the user data and metadata that provides a self-contained description of the user data, encodes the input data into a machine-readable code, and generates a final representation of the electronic document with a display of the machine-readable code. Upon reading the machine-readable code, the metadata can be used to identify a set of fields in a target system to which to assign the user data. In some embodiments, the metadata and the user data can be transformed and sent to a target system. The use of metadata in this manner enables machine-readable codes to maintain a physical representation of data that facilitates transfer of the data back into an electronic environment.

Abstract: A method of delivering data over a computer network in which a CORBA name service runs on a first computer connected to a computer network at a kiosk station, and a subscription agent runs on a second computer connected to the computer network at a user's station. A request is sent from the subscription agent on the second computer to a name service on the first computer for registration on the name service. The request includes a name and an associated internet protocol network address and port number. The request is received at the name service on the first computer. Data is received from a data resource connected to the first computer, the name from the request is displayed in a list of names on a display at the first computer, and user input is received at the first computer selecting the name from the list.

Abstract: Methods and apparatus, including computer systems and program products, for creating and using documents with machine-readable codes. A computer program displays a list of fields in an electronic document, receives user input selecting one or more of the fields, automatically generates generation instructions for a machine-readable code to be displayed in a final appearance of the electronic document, and stores the generation instructions in the electronic document. The generation instructions specify that the machine-readable code is to be produced using data to be provided for the selected fields. In some embodiments, the program can also evaluate the user input, as well as user modifications made to the electronic document, to determine whether the machine-readable code is validly configured. By guiding users through the process of setting up machine-readable codes, the program can help users create forms with machine-readable codes that have a high probability of being scanned and decoded successfully.
