Abstract: A system and method for transferring data representing one or more transactions between computing nodes of a computer network by at least one intermediary node may include: receiving a transaction request, for transferring ownership of a product from a current owner to a subsequent owner, the transaction request being signed by the current owner; authenticating the signature of the current owner; accessing a product chain associated with the product; extracting from the product chain a list of target user entities and a contract data element; producing an ownership block including an identification of the subsequent owner; appending the ownership block to the product chain, to indicate transfer of ownership from the current owner to the subsequent owner; and transferring data representing one or more transactions between the intermediary node and one or more computing nodes based on the transaction request.

Abstract: A system and method for defining and using a virtual currency may include associating a fraction of a currency with at least one of: a history, an attribute, and a constraint; and selecting a usage of the fraction, in a monetary transaction, based on the at least one of: the history, the attribute and the constraint.

Abstract: A method and a system for determining an optimal authentication scheme for an authenticating system. Embodiments may include: receiving, from the authenticating system an identity of a user requiring access to the authenticating system and a policy of the authenticating system; receiving, from a storage device, data including historical information regarding previous authentication attempts by the user; producing a list including an optimal selection of one or more authentication schemes, each including one or more authentication factors, according to the historical information and the authenticating system policy; and sending the selection list of one or more authentication schemes to the authenticating system.

Abstract: A system and method of correcting an anomaly in a split computer network, where the split computer network includes a first subnet, connecting one or more requestor nodes to a first intermediary node, and a second subnet, connecting the first intermediary node to one or more approver nodes may include performing, by at least one processor associated with the first intermediary node: monitoring transactions between the one or more requestor nodes and the one or more approver nodes, via the first intermediary node; analyzing the monitored transactions, to obtain a transaction pattern; probing communication between an examined requestor node and at least one approver node; analyzing the probed communication, in view of the transaction pattern, to identify a suspected transaction anomaly; and producing a suggestion of at least one corrective action, based on the suspected transaction anomaly.

Abstract: A system and method for authenticating a monetary transaction may include scanning a website to identify a plurality of products sold at the website and a respective plurality of costs of the products; calculating a set of monetary transactions based on a respective set of combinations of products; receiving details of a monetary transaction and generating an authentication score for the transaction based on relating data in the monetary transaction to data in the set of monetary transactions.

Abstract: A system and a method of transferring a transaction between a source node and a destination node of a computer network, by at least one processor of an intermediary node may include: receiving a request to transfer the transaction from the source node to the destination node; extracting from the transaction request at least one data element; obtaining from a first database at least one condition element; anonymizing the transaction; and transferring the anonymized transaction from the intermediary node to the destination node, based on at least one of: the at least one condition element and the at least one extracted data element.

Abstract: A system and a method of detection of an attack on a computer network including a plurality of nodes, the method including: associating the plurality of nodes with each other in a distributed ledger configuration; producing, by a requesting node of the plurality of nodes, a request to set a value of at least one key derivation parameter; performing a vote of confidence among a subset of the plurality of nodes regarding the validity of the request; and detecting an attack on at least one node of a plurality of nodes according to the vote of confidence.

Abstract: A system and a method of optimizing an organizational structure (OS) of an organization may include: receiving one or more data elements pertaining to the OS; receiving a value of one or more transaction parameters pertaining to one or more transactions conducted over one or more nodes of a first computer network; perturbating a value of one or more OS elements; creating a simulated computer network based on the one or more perturbated values; for each network of the first computer network and the simulated computer network, calculating a value of at least one OS performance parameter; and generating, based on the calculation, a suggestion for optimizing the OS, wherein the suggestion may include at least one perturbated OS element value.

Abstract: A system and method of routing transactions within a computer network, by at least one processor, including: receiving a transaction request to route a transaction between one of a plurality of source nodes and a destination node of the computer network; extracting from the transaction request one or more transaction parameters pertaining to the destination node; receiving a set of preference weights wherein each preference weight corresponds to a transaction parameter; selecting a source node from the plurality of source nodes based on at least one received preference weight and at least one corresponding transaction parameter; and routing the requested transaction through nodes of the computer network between the selected source node and the destination node.

Abstract: A system and a method of routing transactions between nodes of a computer network, by at least one processor. Embodiments of the method may include: receiving a destination feature vector (DFV) for at least one destination node of a plurality of destination nodes of the computer network; receiving a transaction request to route a transaction between a source node of the computer network and the at least one destination node; extracting from the transaction request one or more transaction parameters; and selecting a destination node from the plurality of destination nodes based on one or more of the transaction parameters and the DFV of the at least one destination node.

Abstract: A system and method of routing transactions within a computer network, by at least one processor may include: receiving a transaction request to route a transaction between a source node and destination node of the computer network; identifying a plurality of available routing paths for propagating the transaction between the source node and destination node; obtaining transaction parameters for each available routing path; receiving a set of preference weights including one or more preference weights, each corresponding to a transaction parameter; selecting one or more routing paths from the plurality of available routing paths, based on the one or more transaction parameters and respective preference weights; producing a routing scheme, comprising an ordered list of the one or more selected routing paths, according to the received set of preference weights; and routing the requested transaction through nodes of the computer network according to the routing scheme.
