The present invention consists of a secure interactive electronic account statement delivery system suitable for use over open networks such as the Internet. The invention utilizes a certification hierarchy to insure that electronic bills, invoices, and other account statements can be securely sent over open networks. The participants in the system are a certification authority, certificated banks, billers, and customers. The certification authority grants digital certificates to the certificated banks, which in turn grant digital certificates to billers and customers. Digital certificates form the basis for encryption and authentication of network communications, using public and private keys. The certificates associate a customer and biller with a certificated bank and with the electronic billing system, much like payment cards associate a customer with a payment card issuer and a particular payment card system. Digital signatures are used for authentication and non-repudiation. The certificates may be stored as digital data on storage media of a customer's or biller's computer system, or may be contained in integrated circuit or chip cards physically issued to billers and customers. The electronic bill itself may be a simple text message containing the equivalent of summary information for the bill, or may be more elaborate. In one embodiment of the invention, the electronic bill contains a number of embedded links, for example an embedded URL of a biller's world wide web server that allows the customer to interactively bring up detailed billing information by activating the link. The e-mail message may also include links to third party websites.

A system and method for limiting access to and preventing unauthorized use of an owner's digital content stored in an information network and available to clients under authorized conditions. The network includes at least one server coupled to a storage device for storing the limited access digital content encrypted using a random-generated key, known as a Document Encryption Key (DEK). The DEK is further encrypted with the server's public key, using a public / private key pair algorithm and placed in a digital container stored in a storage device and including as a part of the meta-information which is in the container. The client's workstation is coupled to the server for acquiring the limited access digital content under the authorized condition. A Trusted Information Handler (TIH) is validated by the server after the handler provides a data signature and type of signing algorithm to transaction data descriptive of the purchase agreement between the client and the owner. After the handler has authenticated, the server decrypts the encrypted DEK with its private key and re-encrypts the DEK with the handler's public key ensuring that only the information handler can process the information. The encrypted DEK is further encrypted with the client's public key personalizing the digital content to the client. The client's program decrypts the DEK with his private key and passes it along with the encrypted content to the handler which decrypts the DEK with his private key and proceeds to decrypt the content for displaying to the client.

Encryption-based data access management may include a variety of processes. In one example, a device may transmit a user authentication request for decrypting encrypted data to a data storage server storing the encrypted data. The computing device may then receive a validation token associated with the user's authentication request, the validation token indicating that the user is authenticated to a domain. Subsequently, the computing device may transmit the validation token to a first key server different from the data storage server. Then, in response to transmitting the validation token the computing device may receive, from the first key server, a key required for decrypting the encrypted data. The device may then decrypt at least a portion of the encrypted data using the key.

A server architecture for a digital rights management system that distributes and protects rights in content. The server architecture includes a retail site which sells content items to consumers, a fulfillment site which provides to consumers the content items sold by the retail site, and an activation site which enables consumer reading devices to use content items having an enhanced level of copy protection. Each retail site is equipped with a URL encryption object, which encrypts, according to a secret symmetric key shared between the retail site and the fulfillment site, information that is needed by the fulfillment site to process an order for content sold by the retail site. Upon selling a content item, the retail site transmits to the purchaser a web page having a link to a URL comprising the address of the fulfillment site and a parameter having the encrypted information. Upon following the link, the fulfillment site downloads the ordered content to the consumer, preparing the content if necessary in accordance with the type of security to be carried with the content. The fulfillment site includes an asynchronous fulfillment pipeline which logs information about processed transactions using a store-and-forward messaging service. The fulfillment site may be implemented as several server devices, each having a cache which stores frequently downloaded content items, in which case the asynchronous fulfillment pipeline may also be used to invalidate the cache if a change is made at one server that affects the cached content items. An activation site provides an activation certificate and a secure repository executable to consumer content-rendering devices which enables those content rendering devices to render content having an enhanced level of copy-resistance. The activation site “activates” client-reading devices in a way that binds them to a persona, and limits the number of devices that may be activated for a particular persona, or the rate at which such devices may be activated for a particular persona.

A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Improved techniques to partially encrypt media files are disclosed. The encryption serves to cryptographically secure only a portion of the media data within a media file, while the remaining portion of the media data is not cryptographically secured. Although only partial encryption is used, the portion being encrypted serves to substantially disrupt usefulness of other parts of the media file which are not encrypted. In other words, the partial encryption renders the media file substantially unusable by unauthorized users. In one embodiment, the partial encryption is performed by a host device and thereafter the partially encrypted media file is delivered to a client device. The client device, if authorized, can subsequently decrypt the partially encrypted media file and utilize (e.g., play) the media file. However, since the media files are only partially encrypted, the decryption is likewise also only partial, which makes decryption faster and less resource intensive.
