A system and method of generating index information for electronic documents. The system includes a client, one or more information retrieval (IR) engines, such as a search engine, which are each in communication with each other via a network. In one embodiment of the invention, the server maintains a plurality or data objects that are protected by digital rights management (DRM) software. Upon receiving a network request from one of the IR systems, the server dynamically generates an electronic document that provides index information that is associated with one of the data objects. In one embodiment of the invention, the server dynamically generates the contents of the electronic document based upon the indexing characteristics of the IR system. Furthermore, upon receiving a network request from one of the client, the server determines whether the client is authorized to access the data object that is associated with the network request. If the client is authorized to access the data object, the server transmits the data object to the user.

A system for providing rights controlled access to digital media comprises a server data processor and a client data processor connected by a communications network. The user data processor provides access to a data object in accordance with rules associated with the data object by the server data processor. The client data processor comprises a machine key device and a user key device. The machine key device is preferably an installed component of the client data processor that provides encryption, decryption, and authentication functionality for the client data processor. The user key device is preferably a removable, portable device that connects to the client data processor and provides encryption, decryption, and authentication functionality for the user. A method restricts the use of a data object to a particular user and a particular data processor through the use of additional layers of encryption. The method preferably comprises encrypting a data object such that the it can be decrypted by the machine key device, and further encrypting the data object such that it can be decrypted by the user key device.

A client and one or more information retrieval (IR) engines, such as a search engine, may be in communication with each other via a network. A computer may read index information associated with at least a portion of an audiovisual object, the index information structured to be used in an index database of a search engine system. The computer may obfuscate at least a portion of the index information so that the intelligibility of the contents of the index information is reduced, and may transmit at least some of the obfuscated index information to the search engine system.

A method and a system for managing a data object so as to comply with predetermined conditions for usage of the data object. To control the usage of the data object, a set of control data, defining uses of the data object, which comply with the predetermined conditions, is created for the data object. The data object is concatenated with the user set of control data, encrypted and transferred to the user. When the user wants to use the data object, a special user program checks whether the usage complies with the control data. If so, the usage is enabled. Otherwise it is disabled.
