Abstract: A system and method for automatic, rapid, and auditable updates of digital contracts allows participants to make agreed upon changes to a digital contract that is auditable and fast, so as to improve security, as well as reduce maintenance and operations costs of the management and execution of digital contracts.

Abstract: A system and method for destroying data stored on an immutable distributed ledger utilizes technology from the following fields: encryption, digital signatures, data structures, distributed storage, distributed ledger technology, and smart contracts. Immutable distributed ledgers provide benefits for sensitive data, including availability, integrity, and data processing visibility. The system and method places sensitive data on an immutable distributed ledger and maintains these advantages of immutable distributed ledgers. The system and method also supports the efficient deletion of this sensitive data without compromising the integrity of the ledger.

Abstract: A system and method for efficient and secure private similarity detection for large private document repositories reduces the amount of trust that the participants need to give to a third party and detects malicious participants. One use of this system and method is the efficient and secure detection of similar documents across large private document repositories.

Abstract: A system and method for the secure management of digital contracts utilizes technology from the following fields: digital timestamping, encryption, distributed storage, and distributed payment systems. The existing state-of-the-art contract management systems require counter-parties to give a substantial level of trust to third parties to perform functions such as storage and verification. This system and method reduces the amount of trust that the counterparties need to give to a single third party. The system and method may be used for the secure construction and management of digital contract data and metadata.
