Method and system for linking an anonymous electronic trade order to an identity of a trader
View Patent ↗A method for automatically linking an anonymous electronic trade order having an order quantity (q) to an identity of a trader by providing an identity marker (s) of the trader; embedding the identity marker (s) by splitting the anonymous trade order into a number (n) of trade orders each having a corresponding order quantity x (i) to generate a trade order set; and placing the generated trade order set in an electronic order book.
1. A method for automatically linking an anonymous electronic trade order having an order quantity (q) to an identity of a trader comprising the following steps:
(a) receiving an identity marker of a trader;
generating a cryptographic signature (S) by said trader using a private key of said trader;
embedding said cryptographic signature (S) by splitting said anonymous trade order into a number (n) of shorter-bit-length trade orders having available bits and each having a corresponding order quantity x(i) to generate a trade order set by placing bits of the cryptographic signature in available bit locations of trade orders in said trade order set; and
placing the generated trade order set in an electronic order book.
2. The method according to claim 1 , wherein a public key and the identity of said trader is made available through a separate communication channel.
3. The method according to claim 1 , wherein the public key and the identity of said trader is placed on a website.
4. The method according to claim 1 , wherein the cryptographic signature is generated by an elliptic curve signature generation algorithm.
5. The method according to claim 1 , wherein the embedding is performed by a direct mapping algorithm.
6. The method according to claim 1 , wherein a cryptographic signature is extracted from the order quantities x(i) of the placed order set placed in the electronic order book to determine an identity of a trader for the trade order set.
7. The method according to claim 6 , wherein it is checked whether the derived cryptographic signature is a valid cryptographic signature of the trader.
8. A computer program product for performing a method for automatically linking an anonymous electronic trade order having an order quantity (q) to an identity of a trader comprising the following steps:
(a) receiving an identity marker of a trader;
generating a cryptographic signature (S) by said trader using a private key of said trader;
embedding said cryptographic signature (S) by splitting said anonymous trade order into a number (n) of shorter-bit-length trade orders having available bits and each having a corresponding order quantity x(i) to generate a trade order set by placing bits of the cryptographic signature in available bit locations of trade orders in said trade order set; and
placing the generated trade order set in an electronic order book.
