Abstract

The disclosed embodiments relate generally to complex data stream control and entitlement. Specifically, the disclosed embodiments provide systems and methods for ensuring that only authenticated/verified participants receive data streams. A third party, e.g., a party other than the data provider or the data recipient, who is nevertheless associated with both the data provider and the data recipient, may be involved in controlling whether data streams from the data provider can reach the data recipient. Thus, a third party may logically sit between the data provider and the data recipient, and may decide whether the data recipient should receive data streams. The disclosed embodiments implement data generation, flow, control and permissioning between multiple entities via digital assets accessed and manipulated on a shared data structure.

First claim

What is claimed is:

1. A computer implemented method comprising:
generating a data entitlement asset for storage within a distributed electronic ledger shared among a plurality of participant computing systems, the plurality of participant computing systems including at least an exchange computing system, a plurality of software vendor systems, and a plurality of trading firm systems each including one or more trading devices, wherein the exchange computing system generates market data indicating modifications to at least one data object based on at least one of a plurality of electronic data transaction request messages received by the electronic trading system, and transmits the market data to the plurality of software vendor systems for redistribution to one or more trading devices upon validation of a data entitlement asset for a respective trading device by a respective software vendor system, the data entitlement asset stored in the distributed electronic ledger, the generating further comprises:
identifying, by the processor, a data entitlement request stored in the distributed electronic ledger by a trading device of the one or more trading devices, the data entitlement request comprising a request for access to at least a portion of the market data;
validating, by the processor, the data entitlement request;
automatically generating, by the processor, the data entitlement asset; and
storing, by the processor, the generated data entitlement asset in the distributed electronic ledger for validation by the software vendor system, the data entitlement asset configured to provide access to the trading device for the requested portion of the market data.

2. The computer implemented method of claim 1 wherein the request for access to the market data comprises a request for access through software operated by a software vendor system for the trading device.

3. The computer implemented method of claim 1 , wherein the data entitlement request comprises: (i) an identification of the trading device which stored the data entitlement request in the distributed electronic ledger, (ii) the requested access, and (iii) data indicative of a transfer of payment.

4. The computer implemented method of claim 3 , wherein validating the data entitlement request includes determining a required payment based on the identification of the trading device which stored the data entitlement request in the distributed electronic ledger and the market data requested in the data entitlement request, and determining that a payment satisfies the required payment.

5. The computer implemented method of claim 3 , wherein the exchange computing system is further operative to encrypt the market data with a public key corresponding to a private key owned by the trading device which stored the data entitlement request in the distributed electronic ledger, the private key useable for decrypting the market data indicating the modifications to the at least one data object.

6. The computer implemented method of claim 3 , wherein the exchange computing system is further operative to encrypt the market data with a symmetric shared key and encrypt the symmetric shared key with a public key corresponding to a private key owned by the trading device which stored the data entitlement request in the distributed electronic ledger, the private key useable for decrypting the symmetric shared key and the symmetric shared key useable for decrypting the market data.

7. The computer implemented method of claim 1 , wherein each of the plurality of software vendor systems is configured to, upon detecting an attempt by the trading device to access market data redistributed by the software vendor system, query the distributed electronic ledger for a data entitlement asset associated with (i) the trading device that which attempted access and (ii) the requested market data before providing the trading device which attempted access with access to the requested market data.

8. The computer implemented method of claim 1 , wherein the data entitlement asset, upon being stored in the distributed electronic ledger by the exchange computing system, is replicated in each of the plurality of participant computing systems.

9. The computer implemented method of claim 1 , wherein each of the plurality of software vendor systems are configured to provide one or more of the one or more trading devices with a user interface to access the requested market data.

10. The computer implemented method of claim 1 , wherein the plurality of electronic data transaction request messages includes requests to perform transactions related to financial instruments represented by the at least one data object.

11. The computer implemented method of claim 10 , wherein the transactions include purchasing or relinquishing a financial instrument.

12. The computer implemented method of claim 1 , wherein each of the at least one data object represents an order book for one or more financial instruments transacted by the exchange computing system.

13. A system comprising:
a data entitlement asset generator operative to generate a data entitlement asset for storage within a distributed electronic ledger shared among a plurality of participant computing systems, the plurality of participant computing systems including at least an exchange computing system, a plurality of software vendor systems, and a plurality of trading firm systems each including one or more trading devices, wherein the exchange computing system generates market data indicating modifications to at least one data object based on at least one of a plurality of electronic data transaction request messages received by the electronic trading system, and transmits the market data to the plurality of software vendor systems for redistribution to one or more trading devices upon validation of a data entitlement asset for a respective trading device by a respective software vendor system, the data entitlement asset stored in the distributed electronic ledger, the data entitlement asset generator including a computer processor coupled with a memory, the computer processor specifically configured to:
identify a data entitlement request stored in the distributed electronic ledger by a trading device of the one or more trading devices, the data entitlement request comprising a request for access to at least a subset of the market data;
determine whether the data entitlement request is valid; and
upon determining that the data entitlement request is valid, automatically generate a data entitlement asset and store the generated data entitlement asset in the distributed electronic ledger for validation by the software vendor system, the data entitlement asset being operative to enable access by the trading device to the requested subset of market data.

14. The system of claim 13 , wherein the request for access to at least the subset of the market data comprises a request for access through software operated by a software vendor system for the trading device.

15. The system of claim 13 , wherein the data entitlement request comprises: (i) an identification of the trading device which stored the data entitlement request in the distributed electronic ledger, (ii) the requested access to the data indicating the modifications to the at least one data object, and (iii) data indicative of a transfer of payment.

16. The system of claim 15 , wherein the computer processor is further specifically configured to determine whether the data entitlement request is valid by determining a required payment based on the identification of the trading device which st
