Abstract: Systems and methods are provided for interconnecting proxy directories, through core proxy services. One example computer-implemented method includes receiving, by a first proxy service core computing device, from a participant, a proxy lookup request, where the proxy lookup request includes a proxy and based on one or more routing rules, submitting the proxy lookup request to a second proxy service core computing device. The method also includes receiving, by the first proxy service core computing device, from the second proxy service core computing device, a proxy lookup response, which includes account data linked to the proxy, and returning the proxy lookup response, to the participant, in response to the proxy lookup request.

Abstract: Systems and methods are provided for deploying keys in connection with proxy resolution. One example computer-implemented method includes distributing, by a service core computing device, a root certificate signed by a certificate authority and an intermediate certificate, which is signed by a root private key associated with the root certificate, and receiving, from a participant, a signing request for a participant certificate including a participant public key. The method also includes assessing, by the service core computing device, the signing request for the participant certificate and signing, by the service core computing device, the participant certificate with an intermediate public key included in the intermediate certificate. The method then includes disseminating the signed participant certificate to the participant and another participant, whereby the participants on the participant certificate based on the participant certificate being signed by the intermediate public key.

Abstract: A data processing method comprising: recording a plurality of electronic value transfers occurring between a plurality of parties; performing an optimisation process on a matrix indicative of a value of each of net electronic value transfers between each of the parties, wherein the matrix is indicative of a relationship between a first electronic store of value held by each of the parties before execution of the net electronic value transfers and a second electronic store of value held by each of the parties after execution of the net electronic value transfers, and the optimisation process comprises selecting a portion of the electronic value transfers for determining the net electronic value transfers indicated by the matrix so as to minimise a difference between the first and second electronic stores of value held by each of the parties; and outputting the selected portion of the electronic value transfers for processing.

Abstract: A method comprising: receiving a first instruction from a first user, the first instruction being an instruction to transfer to a first value from a first institution to a second institution; receiving a second instruction from a second user, the second instruction being an instruction to transfer a second value from the second institution to the first institution, wherein the first value is greater than the second value; calculating the difference between the first value and the second value; and comparing the calculated difference to a predetermined amount, wherein if the calculated difference is greater than the predetermined amount, the method comprises: automatically notify the second institution.
