Abstract: A method to securely distribute media content such as Audio or Video with associated media information as part of a media package, in a media distribution system. The media content is encrypted and can be decrypted using a code, process or algorithm called a program key which is further encrypted and stored in the media package as one or both of a service encrypted program key or a locally encrypted program key. When a payment arrangement is not required the program key can be obtained by decrypting the locally encrypted program key, but when a payment arrangement is required, the locally encrypted program key cannot be decrypted or is not present and the service encrypted program key must be decrypted using a decryption message provided by a server after the payment arrangement is made. Media content, the locally encrypted program key and the service encrypted program key are re-encrypted periodically to ensure the security of the media package.

Abstract: Disclosed are non-volatile memory devices that incorporate a series of single or double memory cells. The single memory cells are essentially “U” shaped. The double memory cells comprise two essentially “U” shaped memory cells. Each memory cell comprises a memory element having a bi-stable layer sandwiched between two conductive layers. A temporary conductor may be applied to a series of cells and used to bulk condition the bi-stable layers of the cells. Also, due to the “U” shape of the cells, a cross point wire array may be used to connect a series of cells. The cross point wire array allows the memory elements of each cell to be individually identified and addressed for storing information and also allows for the information stored in the memory elements in all of the cells in the series to be simultaneously erased using a block erase process.

Abstract: Apparatus, methods and computer programs provided for metering and accounting in a commercial e-services infrastructure address the requirement for handling composite services in which higher-level services are built using simpler underlying services, each of which may be autonomously owned and operated. Metering records for each service underlying a composite service are correlated by a process associated with the composite service, and then sent to an accounting service where they can be aggregated. The correlation is performed in a distributed manner with correlated usage data provided on a per-request basis. Accounting services can take account of the usage and charges associated with the underlying services to provide accounting and billing on a per-request basis or per customer-provider pair for a billing period.
