A method for managing a plurality of files in a communication network having a plurality of clients includes a server receiving () metadata associated with a secured file stored in a virtual data drive of a first client. The server also receives () data segments associated with the file from the virtual data drive of the first client. The server stores the metadata and data segments associated with the file at the server. The server generates () a first representation of the file based on the received metadata and data segments associated with the file and sends () the first representation of the file to the plurality of clients. Next, the server receives () a request from a second client for at least one data segment of the file. The server authenticates the request based on a plurality of access rights of a user of the second client and sends () the at least one data segment of the file to the second client when the request is authenticated.

Method and system for managing data in a communication network

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.

Monitoring computer performance metrics utilizing baseline performance metric filtering

A method and a system for managing one or more files in a communication network are provided. The system includes a server, a first client, and a second client. When the first client places a file in a virtual data drive of the first client, data segments and metadata associated with the file are uploaded at the server. The server generates a first representation of the file. The server then sends the first representation of the file to the first and second clients. The second client stores the first representation of the file in its local storage. The second client can then send a request to the server to access the file based on the first representation of the file. The requested file is sent to the second client by the server. The sent file is not cached by the second client, if the file is a secured file.

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.

Image-based document display

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.

Controlling access to electronic content

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.
