    摘要: A method for encoding data in a monochrome media utilizing the capability of the media for grayscale resolution. A document is processed to provide an image in electronic format, in which each pixel has an assigned data value with a given bit depth. A mapping operation is performed for generating a monochrome data word (120), preferably having a reduced bit depth. The monochrome data word (120) can be used to encode multiple data fields (114, 116, 118). A printer (92) then produces a preserved document record (90) in which the appropriate monochrome data word (120) determines the grayscale value for each pixel.

    摘要: A method for preserving a digitally signed document (160) in a digital data preservation system (10). A secure preservation request (176) combines the document (160) with a preservation signature (174) that is generated using an identification mark (172) and the document's associated digital signature (168). Once the document (160) is authenticated by the digital preservation system vendor, both the document (160) and the identification mark (172) are recorded onto preservation media (210) in human-readable form.

    摘要: A method for decoding data that has been encoded in a monochrome medium utilizing the capability of the medium for grayscale resolution. A document is processed to provide an image in electronic format, in which each pixel has an assigned data value with a given bit depth. A mapping operation is performed for generating a monochrome data word (120), preferably having a reduced bit depth. The monochrome data word (120) can be used to encode multiple data fields (114, 116, 118). A printer (92) then produces a preserved document record (90) in which the appropriate monochrome data word (120) determines the grayscale value for each pixel. To decode the stored data, a scanner (86) is employed to obtain the grayscale value from the preserved document record (90). For each pixel, the grayscale value is then decomposed into multiple data fields (114, 116, 118), which can then be decoded to provide the information that was originally encoded.

    摘要: A digital preservation system (10) for accepting a digital data record as input, for writing the data record in human-readable form onto a preservation-quality medium (210), for storage of the medium (210), and for retrieval of the data record from the medium (210). The system (10) is modular, allowing scaling of the system (10), allowing preferential selection of specific image handling components, and allowing replacement of complete subsystems while minimizing the likelihood of data loss. The digital preservation system (10) preserves a data record in human-readable form, along with an associated metadata record, allowing the human-readable preserved data record to be readable in the distant future, independent of specific reading hardware.
