Abstract: Disclosed herein are system, method, and computer program product aspects for validating protolanes. For example, the method includes determining a protolane level flowchart from one or more flowcharts corresponding to one or more gates of a protolane selected from a set of protolanes of a geonet, wherein the one or more flowcharts correspond to conditions that can be encountered by an actor approaching the corresponding one or more gates, and wherein the geonet comprises a plurality of lane segments associated with the set of protolanes. A graph through the protolane level flowchart is generated that corresponds to actions of an actor. Reasoning of the actor is validated by testing the actions of the actor against the graph through the protolane level flowchart.

Abstract: Techniques for proving authenticity of data files, such as digital photos. An authentication/indexing server content from a client device such as a mobile device, and generates or receives other related data such as a reference to the content object, a fingerprint for the content object, and other metadata indicating for example a timestamp related to the content object. The fingerprint is inserted into a distributed ledger, with the distributed ledger returning a ledger address. A manifest object containing the transaction object, the ledger address, and a list of the content object and, optionally, related edits is then created and stored. The server may index fingerprints. Thus, a fingerprint can be used to authenticate subsequently received object against the stored metadata.

The sliding deadbolt includes a first anti-thrust cam configured to restrain the sliding deadbolt in the locked position, and a release driver arranged such that, when driven, the release driver releases the first anti-thrust cam from restraining the sliding deadbolt in the locked position and slides the deadbolt to the unlocked position.

Abstract: A digital asset is represented and verified as a set of related digital asset or other content objects. Related metadata is stored on an immutable distributed ledger separately from the content objects themselves. For example, a transaction object includes metadata such as identifiers for two or more content objects, fingerprints for the content objects. The content objects may be stored in a local or cloud object repository. Validation of a later identified content object may include determining a fingerprint for the later identified content object, mapping that fingerprint to an address within the immutable distributed ledger to retrieve metadata previously mapped, and comparing the two fingerprints. Visual validation may be provided when the first and second fingerprints match, such as by displaying a positive icon adjacent the later identified object.
