A system for secure delivery of on-demand content over broadband access networks utilizes a pair of servers of security mechanisms to prevent client processes from accessing and executing content without authorization. A plurality of encrypted titles are stored on a content server coupled to the network. An access server also coupled to the network contains the network addresses of the titles and various keying and authorization data necessary to decrypt and execute title. A client application executing on a user's local computer system is required to retrieve the address, keying and authorization data from the access server before retrieving a title from the content server and enabling execution of the title on a user's local computer system.

Method and apparatus for content protection in a secure content delivery system

Systems and methods for, inter alia, allowing a remote user to access content, such as data or an executable program, on demand from a remoter server. When accessed the content can be delivered on demand to the user's remote workstation for use by the user. As network resources may vary, the systems described herein further include systems that will monitor network resources, and other factors, versus the transfer demands for the content requested by the user. The systems may then determine a schedule, or load map, for transferring blocks of the content in a way that efficiently employs the available resources, and in a way that provides the user with a user-experience that is similar, or substantially similar, to the user-experience that the user would have if the content were stored locally on the user's workstation.

Systems and methods for delivering content over a computer network

A system for secure delivery of on-demand content over broadband access networks utilizes of servers and security mechanisms to prevent client processes from accessing and executing content without authorization. A plurality of encrypted titles are stored on a content server coupled to the network. An access server also coupled to the network contains the network addresses of the titles and various keying and authorization data necessary to decrypt and execute a title. A client application executing on a user's local computer system is required to retrieve the address, keying and authorization data from the access server before retrieving a title from the content server and enabling execution of the title on a user's local computer system.

A system for secure delivery of on-demand content over broadband access networks includes a client application executing on a user's local computer system. The client application interacts with a content server on which a plurality of selectable titles are stored and further interacts with an access server which provides the network address of a title and keying data necessary for to the client process access and execute the title. The client process utilizes an installation abstraction which enables a title to be executed on the local computer system without ever being installed. The abstraction is achieved by mounting a network file system and storing a set of registry entries related to the title on the local computer system. Portions of the title are retrieved from the content server and executed by the local operating system. During title execution, requests from the local operating system are intercepted and redirected to the set of registry entries, as applicable. The times at which the client process may retrieve the title data from the content server are defined by the access server through use of an activator and token.
