Initial data is included in a data structure such as an initial container at an initial entity, along with rules and a data signature of at least a portion of the initial data and other container contents relating to the initial entity and the initial data. Each rule defines at least one condition governing the permissible transfer and processing of the initial data by other entities in a provenance chain. Each receiving entity creates a container of its own to encapsulate received containers, and, after optional processing of its own, such as adding or altering data and rules, digital signature for its container. The digital signatures may be obtained from a hash tree-based signing infrastructure that returns data signatures enabling recomputation of a logically uppermost value of the hash tree. A lineage map of any given container may also be displayed for analysis by a user.
