Abstract
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.
Claims8
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.
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.
