Abstract: An apparatus for use in electronic document control includes a storage device a processor coupled to the storage device. The storage device storing software instructions for controlling the processor that when executed by the processor configure the processor to: receive a signal representing data including an original document, append a unique identifier to the original document to generate a modified document, generate a hash value of the modified document, and transmit the hash value corresponding to the modified document to an electronic distributed ledger.

Abstract: A process includes receiving a signal representing data including event information detailing an event involving a product. A computer processor determines that the event matches a triggering event in an event trigger list stored in an entry of a distributed ledger for the product. The event trigger list includes a change in status of manufacturing and/or shipment of the product. At least a portion of the distributed ledger is stored at a storage device. A rule associated with the triggering event is determined by the processor. The rule was previously stored in a rules section of the entry of the distributed ledger. The rule is executed by the processor by updating the distributed ledger and performing an action associated with the determined rule specified in the rules section.

Abstract: A system includes a first client device that is coupled to a second client device. An apparatus, coupled to the first and second devices, includes a storage device coupled to a processor. The storage device stores software instructions for controlling the processor that when executed configures the processor to generate a listing of expected values and referral events associated with a tracked matter. Each referral event corresponds to a different expected value and the distributed listing includes a sequence of units corresponding to different expected values and corresponding referral events. The processor receives a notification from one of the first or second device that is representative of a referral operation between the first and second location. The processor determines an outcome value for the referral operation and identifies whether the determined outcome value is accurate based on the distributed listing.

Abstract: The disclosed embodiments include computerized systems and methods that generate secured distributed storage ledger structures, such as block-chain-based ledger structures, that facilitate event-based control of tracked assets. In one embodiment, an apparatus associated with a centralized authority of the secured distributed storage ledger may detect an occurrence of a triggering event, and may access and decrypt a set of rules hashed into the secured distributed storage ledger using a confidentially-held master cryptographic key. The apparatus may identify a rule associated with the detected event, and perform one or more operations consistent with the rule and involving at least one of assets tracked within the secured distributed storage ledger or an owner of a portion of the tracked assets.

Abstract: A system includes devices and sensors associated with a construction site for a project. A computing apparatus, communicates with the devices and the sensors, includes a storage device and a processor. The storage device stores software instructions for controlling the processor that when executed by the processor configures the processor to obtain a predetermined construction schedule with terms for the project. The processor obtains sets of data that each corresponds to a different term. The processor generates a distributed listing for the project, which includes a sequence of a plurality of units corresponding to different terms and sets of data. The processor receives a signal from one of the sensors, wherein the signal is representative of a progress event. The processor identifies whether the progress event at the site corresponds to one of the terms in the schedule and updates and saves the distributed listing when a correspondence is identified.
