Abstract: A system and method for associating rendered advertisements with digital content is described. In some examples, the system receives an image of a rendered advertisement, information associated with digital content, and information associating the rendered advertisement with the digital content via a web portal.

Abstract: A system and method for authorizing access to computing resources, access to services, software and so on, based on capturing information associated with a request is described.

Abstract: A system and method for automatically providing content associated with captured information is described. In some examples, the system receives input by a user, and automatically provides content or links to content associated with the input. In some examples, the system receives input via text entry or by capturing text from a rendered document, such as a printed document, an object, an audio stream, and so on.

Abstract: A system and method for identifying a document based on a spectral analysis of the text of the document is described. In some examples, the system generates a document identifier for a rendered document based on assigning values to words in the rendered document, such as values associated with the frequency of use of the word by the rendered document, the absolute or relative position of the word in the rendered document, and so on. The system may use the document identifier to generate a group of documents having similar document identifiers, and choose a likely match from the group of documents based on predictive analysis.

Abstract: A system and method for facilitating interactions between multi-function devices and rendered documents is described. In some examples, the systems overlays an image of a rendered document with display elements associated with actions to perform for the rendered document. In some examples, the system presents a virtual real-time image in place of a real-time of a document or other display of information.

Abstract: A system and method for automatically changing the operation of a mobile device in response to a presence of information is described. In some examples, the system determines an information capture device is proximate to text, automatically changes operation of the capture device to a certain mode, captures the text, and performs an action associated with the captured text.

Abstract: A system for determining viewership of articles or ads in printed publications and using the determined viewership to determine author compensation, ad rates, or other historical or demographic related information is described. The system receives text capture information of portions of a number of rendered documents that is generated by capture devices operated by a number of users. The system searches digital content using the received capture information and determines a readership value for components of the rendered document based upon the search.

Abstract: A facility for storing a text capture data structure for a particular user is described. The data structure comprises a number of entries. Each entry corresponds to a text capture operation performed by the user from a rendered document. Each entry contains information specifying the text captured in the text capture operation.

Abstract: Provided are a method system and program for managing revisions to a file. A new version of a file is received including new modifications to an indicated version of the file. A current version of the file is accessed in response to determining that the indicated version is an earlier version than the current version. The indicated version of the file and the current version are compared to determine previous modifications of the current version over the indicated version. A determination is made as to whether the new modifications in the new version and the previous modifications of the current version affect at least one semantic unit in a conflicting manner with respect to the indicated version.
