Abstract: A system and method for managing performance metric information is provided. Baseline performance metrics, such as network bandwidth capabilities, of various client computing devices may be obtained. The baseline performance metrics can be used to separate client computing devices into one or more groups. Based on the groupings, subsequent performance metrics associated with the one or more monitored groups can be collected in a manner to mitigate performance latencies associated with the baseline performance metric. The subsequent performance metrics can be processed to determine which metrics correspond to a potential performance problem.

Abstract: A system and method for controlling access to electronic content stored on a content provider's server is provided. A content provider may control and restrict unauthorized access to electronic content through an identified user account by limiting a number of devices from which requests to access the content through the account have been received. A content provider may also collect usage information of interest by monitoring authorized access to electronic content.

Abstract: The present invention is directed to a method and system for verifying a user for copying or printing a limited portion of digital content while allowing the user to view the digital content. The digital content may have image portions that are digital images generally scanned from a printed page of the content and text portions that are digital texts including all forms of letters, characters, symbols, etc. An interactive image document displaying image portions of the digital content is provided for secure data access to text portions. A user can request and obtain a limited text portion of the digital content or view the image portions of the digital content via user interactions within the interactive image document. While the text portions can be reproduced, copied, or printed, the image portions can not be re-used or manipulated by the user due to their non-text accessible format.

Abstract: The present invention is directed to a method and system for continuously displaying image pages of digital content which are available over a network. More specifically, the method and system enables a user to view image pages in a continuous manner while a limited number of image pages are being downloaded at a given time. Several image pages which are adjacent to the image page(s) the user is currently viewing may be stored in temporary memory. The image pages in the temporary memory are utilized so that, within the image pages, the user can move the displayed image pages up and down without experiencing any discontinuation. In order to ensure continuous display throughout the entire digital content, the next possible set of image pages is constantly determined and obtained to update the current set of image pages in the temporary memory.
