Abstract: An apparatus has a memory that stores instructions executed by a processor to receive from a source node machine in a network a unique identifier for an object, where the source node machine executes a first instance of an object tracking application. The source node is designated as a parent in a chain-of-custody. The unique identifier and source node information are recorded in an immutable ledger. Updates for the object are received from intermediate node machines in the network. The information updates are recorded in the immutable ledger. A final information update for the object is received from a destination node machine. The final information update is recorded in the immutable ledger. A chain-of-custody map is constructed for the object. The chain-of-custody map is augmented with layers of spatially related data to form a composite chain-of-custody map.
