Title: Renewable traitor tracing
Inventor: LOTSPIECH JEFFREY BRUCE
IPC: H04L9/08
Filed: 2006-09-11
Granted: 2014-10-07
Abstract: A system, method, and computer program product to renewably prevent traitors in a broadcast encryption system from re-using compromised keys. A license agency assigns individual receivers a set of Sequence Keys preferably at manufacture, and assigns Sequence Key Blocks (SKBs) to protected content files to be distributed. The files may be distributed on prerecorded media and typically include several file modifications . The particular modifications in a pirated version of a file can help identify which traitors contributed to its theft. SKBs assigned to new files distributed after traitors have been identified cannot be usefully processed using the compromised keys employed in previous content piracy. Innocent receivers that happen to have compromised key(s) in common with traitors can use a replacement uncompromised Sequence Key from the set to usefully decrypt content. Traitors will however step through all their Sequence Keys without reaching one that will work.

Abstract: A method of determining a flow rate of a pump involves determining a volume capacity for a flow line carrying produced fluids from the pump, determining a starting pressure for the flow line and setting an arbitrary target pressure for the purpose of testing. The test is initiated by preventing flow in the flow line while continuing to operate the pump and monitoring pressure in the flow line to determine a time interval required to reach the target pressure. The method then involves performing calculations to determine flow rate using the volume capacity, the starting pressure, the change in pressure over the time interval required to reach the target pressure. The flow rate is equivalent to .DELTA.V divided by a change in time .DELTA.T. The method is preferably used as part of a manual or automated pump control strategy to keep the pump operating within flow rate ranges that provide optimum pump efficiency.

Abstract: A user accesses a destination such as a call centre 6; the call centre generates a record for insertion into the user's personal address book (e.g. at server 3) with a telephone number of the centre 6 and metadata concerning a transaction. To place a later call on the same matter, the user selects, either using his telephone or via a separate terminal, the address book entry and the call is made. The centre 6 receives the user's telephone number via the calling line identity (CLI) and translates this (at 8) into a data address whereby it can "pull" the metadata from the personal address book at 3. Alternatively the server 3 can translate the centre's telephone number into a data address to "push" the metadata to the centre.

Abstract: Described is a well completion for evenly distributing a viscosity reducing injectant (e.g. steam and/or solvent, e.g. in SAGD or CSS) into a hydrocarbon reservoir (e.g. of bitumen), for evenly distributing produced fluids (most specifically vapor influx) and for limiting entry of particulate matter into the well upon production. On injection, the injectant passes through a limited number of slots in a base pipe, is deflected into an annulus between the base pipe and a screen or the like, and passes through the screen into the reservoir. On production, hydrocarbons pass from the reservoir through the screen into a compartmentalized annulus. The screen limits entry of particulate matter (e.g. sand). The hydrocarbons then pass through the slots in the base pipe and into the well. Where a screen is damaged, the compartmentalization and the slots in the base pipe limit particulate matter entry into the well.
