Abstract: A method and system is disclosed for protected calculation and transmission of sensitive data. The method and system address the problems that arise when calculations must be performed using data that is too sensitive to be seen by others. Applications of the method and system include trading, portfolio management, risk management, auctions, and testing of sensitive military or government data. Two prototypes are described.

Abstract: A method and system is disclosed for creating and operating Residual Value Games. The method and system address the problem of low expected returns on games such as state-run lotteries, casino-style games, online games, and recreational and/or educational activities that may be modeled in game-theoretic terms as games of one or more players. Many of these games and/or activities have a negative expected return: on average, players lose money. By creating one or more Residual Value Accounts, and linking these accounts to the playing of games (or performing recreational and/or educational activities), the expected return may significantly increase.

Abstract: A method and system is disclosed for creating and managing Diversative Financial Instruments. Diversative Financial Instruments are designed to increase the risk-adjusted return of investment portfolios and other collections of assets and/or liabilities. The method and system also addresses the problem of the Regime Switching Effect, which tends to destroy the benefits of investment diversification when it is most needed, i.e., during a financial crisis. By creating Diversative Financial Instruments that are designed to counteract the Regime Switching Effect, diversification benefits may be tailored to the requirements of investors.

Abstract: A method and system is disclosed for creating and using programmable financial instruments. The method and system addresses the problems caused by limiting the scope of financial instruments to inert objects, whether considered as abstract data or in a physical embodiment such as a paper certificate. Applications of the method and system include trading, portfolio management, collateralization, securitization, securities lending, securities borrowing, and credit enhancement.

Abstract: A method and system is disclosed for safe calculation and data transmission. The method and system addresses the problems-that-arise when calculations must be performed using data that is too sensitive to be seen by others. Applications of the method and system include trading, portfolio management, risk management, auctions, and testing of sensitive military or government data.

Abstract: A method and system is disclosed for creating and using non-scalar valued financial instruments. The method and system addresses the problems caused by limiting the value of financial instruments to scalar quantities. Applications of the method and system include recreation, education, therapeutic intervention, and finance.
