Abstract: The present invention provides systems and methods for self-labeling access points with their geographic location from received beacon frames. In particular, the present invention transmits beacon frames including temporary location information from mobile devices. The beacon frames are received by an access point, filtered by the access point and then used to determine a location. Once the location has been determined, the access point uses the determined location to self-label itself by converting the location information to a geographic code and inserting it as part of the SSID of the access point's beacon signal. The present invention also includes a number of methods using geographic codes including a method for generating and transmitting geographic codes for mobile devices, a method for determining a location of an access point, a method for self-labeling an access point, and a method for filtering beacon frames.

Abstract: A system and method for applying a pre-existing physical seal authorization to documents provides for authentication of electronic documents using physical seals and without interrupting the electronic workflow. The system of the present invention includes a seal capture device coupled to a computer, and the computer coupled by a network to a paper-like document server. The seal capture device detects depression of a seal thereon and outputs the image of the seal and other metadata to the computer. The computer stores the metadata in its local log using a logging module. The computer also adds the image of the seal and other metadata to the electronic document being displayed. Finally, the computer sends the metadata for storage in the global log of the paper-like document server, and the authorized document to the next step in the electronic workflow. The paper-like document server stores the metadata in other servers or entangles the global log with the logs of other servers for additional security.

Abstract: A system for device enabled verifiable stroke and image based workflows comprises a plurality of portable computing devices, coupled by a network to a stroke and image workflow server. The portable computing devices include a display, stroke capture capability and a wireless communication capability. The portable computing devices are adapted to receive images, add stroke annotations to the received images, and send the annotated received images. The stroke and image workflow server is coupled to the network for communication with the portable computing devices. The stroke and image workflow server sends and receives documents from the portable computing devices, maintains a log for verification, and implements a paper like workflow and processing the documents. Essentially, this stroke and image workflow server implements paper like workflow and handles the overhead of processing electronic documents so that it is invisible to the user.

Abstract: A graphic user interface combines a position bar for moving between pages in a document and with a page bookmarking or referencing function. The position bar includes a selectable box that can be used to set a reference mark on a particular page of a document. The user interface also interprets input near the position bar to change the page to the page of the reference mark when the input is within a predefined range of the reference mark.

Abstract: A method and system for generating page and document logs for electronic documents. The system includes a plurality of portable electronic devices and a workflow server. The portable electronic devices display a document that receives stroke input and images. A stroke capture device and module generates a log of segments and updates the log in response to a user erasing stroke data. An image capture module captures an image and inserts the image into a document. A logging module generates page metadata for each page within the document and document metadata that includes changes made to the page data. The logging module copies the page metadata and document metadata in response to a request. The copying includes a copy of all the metadata, metadata for selected pages and metadata for redacted content.

Abstract: A method and system for authenticating applications. The system includes a plurality of portable electronic devices, at least one process organizer, at least one module developer, at least one task performer and a workflow server. The process organizer generates an application. The process organizer can request modules from module developers that are incorporated into the application. Alternatively, the process organizer makes an agreement with a task performer to perform tasks to complete the application. The application is transmitted to the workflow server, which includes an online marketplace for displaying and selling the applications. A user purchases the application through the store. A routing module generates a signature and compares the signature to application, module or document metadata and a secret to determine consistency of the data before the application, module or document is routed.

Abstract: The present invention overcomes the deficiencies of the prior art with a system for stroke and image aggregation and analytics. The system is particularly advantageous because it provides a system for distributing page images such as worksheets, examinations or forms to multiple devices. The system allows independent paging and writing on the distributed materials; collection of the strokes added to the distributed pages images; and aggregating and displaying those strokes or summary information in a useful manner. For example, an instructor might receive the current work of the students for a particular examination question and view those strokes in a parallel manner or a combined manner.

Abstract: A multi-provider forms processing system with retry upon failure comprises: a plurality of portable computing devices, a plurality of service providers and a paper-like forms server coupled by a network. The paper-like forms server performs the scheduling, routing, logging, verification and billing for the paper-like processing of compound documents. The paper-like forms server comprises a central schedule, a retry module and a billing module. The multi-provider forms processing system is advantageous because it monitors for failure of transactions, automatically issues a retry or replacement transactions and adjusts the billing for the failed transaction. In particular, the central scheduler tracks and determines when transaction failures occur, and based on these failures revises the billing to users and credits to service providers.

Abstract: A method and system for generating printable certificates to verify log authenticity. A logging module generates a compound document that includes metadata for changes made to pages in a document. Each time a change is made to the document, such as adding stroke data, the logging module updates the compound document with the changes.

The verification module can recreate a transaction and generate a hash that is compared to the certificate to verify that no tampering has occurred with the document.

Abstract: A system for geographic tagging of network access points comprises a plurality of access points that have been configured to provide location information as part of their beacon. Each access point provides a service set identifier (SSID) that includes an encoded value that represents the location of the access point. The use of an encoded location value in the SSID of the access point is particularly advantageous because it does not require any additional hardware be added to the access point or the portable computing device. Moreover, location can be determined by any portable device without establishing a connection to the access point. The portable computing devices are adapted to receive the beacon, extract the location information from the beacon and decode the beacon.
