Out of data being transmitted from a client application A1 to a server application B1, data of which encryption has been determined to be necessary in a frame analyzing means within an intermediate driver A11 of s PC 1 is relayed by use of a total of two TCP sessions consisting of a TCP session 1 between a TCP A14 and a TCP A2, and a TCP session 2 between a TCP A17 and a TCP B3. Relaying the TCP sessions in such a manner makes it possible to achieve a coincidence of a TCP/IP protocol hierarchy between an SSL A16 within the intermediate driver A11 and an SSL B2 within a server 2, which enables certificate information, an encryption algorithm, etc. necessary for starting an SSL session to be automatically exchanged therebetween. As a result, secret data being sent out from the PC can be encrypted without changing the setting of the server or installing any software.

This software enables a financial institution acting as a clearing agent to offer a liquidity pool where their clients can anonymously submit orders for a financial instrument. Many financial markets suffer from reduced liquidity, the causes for which include: 1) fragmentation across multiple markets, 2) fragmentation across a large instrument universe and 3) attempting to trade an illiquid instrument. The software has been developed to uniquely improve available liquidity using crossing algorithms that intelligently identify orders for similar instruments as relevant execution opportunities, and applies a quantitative scoring of their propensity to trade on which clients can anonymously negotiate and execute. As crossing algorithms are not constrained by the conventional restriction that orders must be for identical instruments, the system is able to increase liquidity by identifying execution opportunities that existing markets cannot, while employing an anonymous negotiation process that minimizes information leakage to mitigate disruption to market prices.
