Abstract: Aspects of the invention relate to a computer-implemented method of improving the efficiency of an electronic collateralisation search engine that uses assets distributed on one or more remotely-located asset depositories. The method comprises selecting from a database of asset records of the remotely-located assets of a collateral giver, a subset of asset records having asset characteristics that satisfy a collateral giver's one or more predefined threshold criteria. Restricting a received search of collateral giver's asset records, which match a collateral receiver's query, to the subset of collateral giver's asset records.

Abstract: A system is designed for processing instructions in real time during a session. This system comprises: a preloader for obtaining reference data relating to the instructions, the reference data indicating the current values of each specified resource account data file, and the preloader being arranged to read the reference data for a plurality of received instructions in parallel from a master database; an enriched instruction queue for queuing the instructions together with their respective preloaded reference data; an execution engine for determining sequentially whether each received instruction can be executed under the present values of the relevant resource account files and for each executable instruction to generate an updating command; and an updater, responsive to the updating command from the execution engine (for updating the master database with the results of each executable instruction, the operation of the plurality of updaters being decoupled from the operation of the execution engine.

Abstract: System and method for securely transferring rights comprising an ownership log of holding transfer certificates, wherein each holding transfer certificate contains data associated with an asset and is recorded against a public key of the owner of the holding. A transaction processor configured to transfer ownership of holdings, the transaction processor configured to receive a first block of data digitally signed by a first owner and having a first holding transfer certificate digitally signed by the first owner, the first block of data describing a first holding offered by the first owner in exchange for a requested second holding. Receive a second block of data digitally signed by a second owner and having a second holding transfer certificate digitally signed by the second owner, the second block of data describing a third holding offered by the second owner in exchange for a requested fourth holding.
