摘要： At least one node in a distributed hash tree verification infrastructure is augmented with an identifier of an entity in a registration path. A data signature, which includes parameters for recomputation of a verifying value, and which is associated with a digital input record, will therefore also include data that identifies at least one entity in the hash tree path used for its initial registration in the infrastructure. An uppermost value of the hash tree verification infrastructure is entered as, or as part of, a transaction in a blockchain.

摘要： Control of access by a requesting entity to an asset includes defining an approved state of the requesting entity. A validation of a representation of the approved state of in a non-repudiatable form in obtained from an event validation system. The requesting entity is triggered to determine its current state by an access-control entity, which compares the current state with the approved state and allows access by the requesting entity to the asset only if the current state is the same as the approved state. In a pre-authorization procedure, one or both of the entities issues a data set challenge to the other, which then validates the challenge via the event validation system and returns this validation to the challenging entity, which then checks the validation to see if it is correct. Data sets may be validated, for example, with hash tree based signatures or blockchain entries.

摘要： A distributed hash tree-based authentication system for digital input records has more than one upper-level core node, each of which receives at least one uppermost value from aggregators. Communicating with each other about which aggregator values they have received, the nodes try to reach agreement as to which of these values should be included in duplicated current intra-node hash tree evaluations so as to form a consistent top-level value used as the basis for digital signatures associated with the digital input records. The top-level value is then entered either directly, or after combination with other top-level values over a period, into a block of a blockchain.

摘要： A code is added as a marking to a document and encodes an identifier that maps to a copy of the document stored in a database. Database copies of stored documents are preferably digitally signed. Using a device such as a smart phone, a user may extract the document identifier from the marking on a purported authentic version of the document and retrieve a copy of the document from the corresponding location in the database. The user can then visually compare the purported authentic version of the document with the retrieved database copy.

摘要： Access by a requesting entity to an asset is authorized by an access-controlling entity, which transmits to the requesting entity a challenge data set and then receives from the requesting entity a response purportedly corresponding to a representation of the challenge data set in a non-repudiatable form, obtained from an event validation system. The access-controlling entity queries the event validation system to determine whether the response does correspond to a correct representation of the challenge data set in the non-repudiatable form, and authorizes the requesting entity for access only if the response is correct representation. Non-repudiation can be established through entry into a blockchain, or using a hash-tree-based digital signature infrastructure.

摘要： Location data from one or more geolocation engines such as GPS, a system that determines location from relative signal strengths or transit times, etc., within and/or connected to a device, such as a mobile phone, vehicle, movable electronic device, computer, etc., is included in a digital record that submitted to obtain a digital signature such that the presence of the device at the particular location can later be proven. The digital record may include data that encodes a message, as well as other parameters such as time. The digital signature encodes recomputation parameters of a hash tree signature infrastructure to a highest level value, a function of which is submitted as a transaction in a blockchain.

摘要： Occurrence of an event is detected within a device such as a computer, a communications device, a machine or process component. A non-deterministic time value (NDT) is requested for and associated with the detected event. Each NDT value is generated as a function of a calendar value created at time intervals as a root hash value of a distributed, hash-tree document authentication infrastructure.
