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 multi-provider forms processing system with a quality of service rating includes 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 comprises a central scheduler and service provider manager and rater. The multi-provider forms processing system provides ratings for the service providers that are used in selection of services providers and processing of compound documents. In particular, the central scheduler tracks and determines where transaction failures occur, and based on these failures provides a quality of service rating for each service provider. The central scheduler also monitors the logs for completion as well as restarts, attempts, failure, reworked and re-performed transaction steps and provides ratings that can be reviewed by a user in selecting a service provider or automatically by a selection module.

Abstract: A method and apparatus for reformatting electronic documents is disclosed. In one embodiment, the method comprises performing layout analysis on an electronic version of a document to locate text zones, assigning attributes for scale and importance to text zones in the electronic version of the document, and reformatting text in the electronic version of the document based on the attributes to create an image.

Abstract: A method of generating an output image having a lower resolution than that of a source image is provided. A thinned image is generated by discarding outer pixels of the source image. In parallel with generation of the thinned image, an averaged image is generated, such that each pixel of the averaged image represents an average of a subset of pixels in the source image. A first output image is then generated by subsampling the pixels of the thinned image. A final output image is generated as a function of both the first output image and the averaged image.

Abstract: A method and apparatus for automatically publishing content based identifiers are described. In one embodiment, the method comprises accessing an electronic communication to obtain a content based identifier (CBI) contained in the electronic communication. In one embodiment, the method may also comprise using the CBI to validate integrity of a hash chained log.

Abstract: A method and apparatus for concealing errors using lower resolution images for compressed images is described. In one embodiment, the method comprises receiving a codestream data of an image and determining a location of an error region in coefficients using an icon.

Abstract: A compression and decompression system in which a reversible wavelet filter are used to generates coefficients from input data, such as image data. The reversible wavelet filter is an efficient transform implemented with integer arithmetic that has exact reconstruction. The present invention uses the reversible wavelet filter in a lossless system (or lossy system) in which an embedded codestream is generated from the coefficients produced by the filter. An entropy coder performs entropy coding on the embedded codestream to produce the compressed data stream.

Abstract: In one embodiment, the system comprises a server and a client. The server stores a compressed codestream corresponding to image data. The client is coupled to the server via a network environment. The client includes a memory having an application and a data structure stored therein. The data structure identifies positions of packets of the compressed codestream on the server and identifies data of the compressed codestream already buffered at the client. The client requests bytes of the compressed codestream from the server that are not already stored in the memory and generates decoded image data requested by a user from the bytes of the compressed codestream requested from the server and any portion of the compressed codestream previously stored in the memory necessary to create the image data.

Abstract: Compound document images are usually high resolution and high quality images that include color, graphics, and images in addition to text. The need for good compression is important for storage and transmission. Due to the large size, even compressed, it is often difficult to access document images quickly and efficiently for display on monitors. The nascent JPM file format enables the best compound document image compression in terms of rate-distortion. However, the access into a JPM file is limited by the access features of the coders used. JPEG 2000 is an image coding system that allows access to lower resolutions, progressive bit-rates, and regions of interest.

Abstract: A method and apparatus for performing progressive order conversion is described. In one embodiment, a system comprises a memory and a progressive order conversion parser. The memory stores a compressed image as a codestream in a first progression order and the progression order conversion parser converts the codestream from the first progression order to a second progression order different than the first progression order.

Abstract: A multimedia output device having embedded encryption functionality enables the outputting of content in an encrypted form. The multimedia output device receives the content to be encrypted, encrypts the content, and generates an electronic output of the encrypted content. The multimedia output device also generates an associated paper output that provides information about the decryption, such as a key, an identification of the electronic output of the encrypted content, and optionally a description of the contents of the content encrypted.

Abstract: Electronic Paper Displays can suffer from “ghosting” or previous images remaining partially visible after the display has updated to show a new image. A pseudo-random noise intermediate image is used to make the ghosting less visible to human observers. Further, other intermediate images can be used to convey visible information or to convey secret information, e.g. a watermark. A control signal for driving the bi-stable display from the current optical state to an intermediate state, then to a final optical state is also determined. In some embodiments, the intermediate state for each pixel is determined in a pseudo-random manner. The pseudo-random noise values are applied to the bi-stable display to remove noise and other artifacts from the end resulting images. The determined control signal is applied to the bi-stable display to drive the bi-stable to the intermediate state, then to the final optical state.

Abstract: A secure system for executing program code in an insecure environment while making it impossible, or at least impractical, to determine how to copy the program code and associated data is provided. A program memory contains encrypted program data and security circuitry contained within an integrated circuit is provided for decrypting the program data as it is needed by a processor. A portion of the processing steps which would be done by the processor in an insecure system is performed in this secure system within the secure circuitry using portions of the decrypted program data which are not provided to the processor. Program data is parsed it out based on a proper request to the security chip from the processor. A key value stored in volatile memory is used in the decrypting process and the volatile memory is positioned on the integrated circuit such that its contents are lost before a chip peel provides access to the volatile memory.
