Abstract
A method may include receiving data and first path-metadata. The first path-metadata may include a first entity identifier. The first entity identifier may be associated with a first receiving entity that receives the data and the first path-metadata from an originating entity. The first path-metadata may also include a first digital signature associated with the originating entity. The method may further include receiving second path-metadata that may include the first path-metadata and a second entity identifier associated with a second receiving entity. The second path-metadata may also include a second digital signature associated with the first receiving entity. The method may additionally include verifying that the data was communicated by the originating entity to the first receiving entity and from the first receiving entity to the second receiving entity based on the first path-metadata, the second path-metadata, the first digital signature, and the second digital signature.
