Abstract: An escrow system that comprises correlating confidential data defining a fixed condition or set of conditions for a release of escrow with data presented in an indefinite series of confidential presentations seeking to satisfy that condition or set of conditions. The system involves a process whereby the conditions for a release of the escrow are fixed (i.e. reduced to writing and not subject to change for a specified period of time) but are not fully disclosed to a party seeking a release of the escrow. Instead, a party seeking a release of the escrow is permitted to submit an indefinite number of confidential presentations seeking to satisfy all of those fixed conditions, both disclosed and undisclosed. The fact and contents of each such presentation are treated as confidential unless the presentation results in a determination by the System that all of the fixed conditions have been satisfied.
