Unlocking digital content embodied in digital readable form on a digital media carrier includes receiving a scanned image of a page from scanning a physical copy of content, evaluating the scanned image; and if the scanned image corresponds to a selected page of the digital content, unlocking the digital content.

Optical character recognition technique for protected viewing of digital files

Unlocking digital content embodied in digital readable form on a digital media carrier is described. Unlocking the digital content includes evaluating a code provided by a user scanning a tag attached to a printed, physical copy of the digital content; and if the code corresponds to an authorized code, unlocking the digital content.

Tags for unlocking digital content

Unlocking digital content embodied in digital readable form on a digital media carrier includes generating a test based on text that is printed in a physical copy of the digital content, prompting a user to input text that appears on a specific page of the physical copy, evaluating whether the user entered the correct word; and if the word was correct, unlocking the digital content.

Techniques for protected viewing of digital files

A method executed on a server for unlocking digital content includes receiving a message corresponding to a request to access digital content embodied in digital readable form, associated with an electronic representation of a publication, sending a test that is based on the user having physical possession of the publication; receiving and evaluating an answer to the test to determine whether the correct answer was received; and if the answer was correct, providing access to the digital content associated with the electronic representation of the publication.

Unlocking digital content on remote systems

A computer program product for compressing data files representative of an image document. The document includes color information and/or graphical information. The product is on a computer readable medium and includes instructions for causing a computer to provide a first image file at a first resolution and a second image file at a second resolution of said document with said second resolution being lower than said first resolution. The product causes a computer to process the first image file to convert the first image file into a text file representation of the document and compress the text file representation of the document to provide a first compressed file. The computer processes the second file to extract information corresponding to color information and graphics information. It compresses the second file using a second, different compression technique to provide a second compressed file corresponding to the image and the color information from the low resolution image file. The product causes a computer to store said first and second compressed files to provide a composite file corresponding to the compressed file of the document.

Compression/decompression algorithm for image documents having text, graphical and color content

A reading system includes a computer and a mass storage device including software comprising instructions for causing a computer to accept an image file generated from optically scanning an image of a document. The software convert the image file into a converted text file that includes text information, and positional information associating the text with the position of its representation in the image file. The reading system has the ability therefore to display the image representation of the scanned image on a computer monitor and permit a user to control operation of the reader by with respect to the displayed image representation of the document by using the locational information associated with the converted text file. Also described are techniques for dual highlighting spoken text and a technique for determining the nearest word to a postion selected by use of mouse or other pointing device operating on the image representation as displayed on the monitor.

Closest word algorithm

A method for having a reading machine spell a word includes retrieving a word to be spelled, displaying the first character of the word on a display while applying a highlighting indicia to the character, synthesizing speech for the character to have the reading machine pronounce the displayed letter of the word, unhighlighting the displayed letter of the word, and retrieving a subsequent letter of the word.

Speller for reading system

Compression/ decompression algorithm for image documents having text

A reading machine includes computer program residing on a computer readable medium operable with an operating system that permits the production of windows on a display. The program has instructions for causing a computer to provide a first user selected call a first user selected routine in response to a user selecting a first word that the user seeks assistance in understanding and produce a text file for the first selected word comprised of data that assists the user call. An operating system routine commands the operating system to create a new window on the display and fill the new window on the display with the information contained in the text file. A second user selected call to a user selected routine can be provided for word that the user seeks assistance in understanding to provide a recursive enrichment feature.
