Abstract: Methods, systems, and computer-readable storage media for notarized communication between platform systems is provided. A first data object is notarized by storing a first root hash value at a blockchain network. The first root hash value is notarized in response to a transaction request received through a first notarization interface instantiated at a first platform system. A subscription for the first platform system is established to provide notification events in relation to a second data object. The first root hash value comprises an object reference to a second root hash value for the second data object. A notification event is sent for the second data object to the first platform system, comprising a third root hash value of a third data object associated with the second data object. The third data objects is notarized at the blockchain network by the second platform system through a second notarization interface.

Abstract: Methods, systems, and computer-readable storage media for federated data management between partner systems is provided. A hash structure is generated for a first data object and includes a first root hash value. The hash structure maps properties of the first data object with corresponding visibility levels for the first data object. The first root hash value is notarized to store the first root hash value in a blockchain network. A request is received to share data for the first data object from a first partner system to a second partner system. The first partner system determines the data to be shared with the second partner system based on a visibility criteria defined in relation to the first data object and the second partner system. The data and a hash proof for the data for verification of authenticity of the data is shared with the second partner system.

Abstract: Systems and methods for using blockchain technology for the purpose of securely identifying parties to a communication. The method may comprise receiving a request to establish a communications connection between a first entity and a second entity in a telephony environment and writing a first digital identity associated with the first entity to a first data block in an immutable chain of blocks, in response to determining that the first entity is recognizable as a trusted entity. The blocks may be associated according to a defined cryptographic relationship. A second digital identity associated with the second entity may be written to a second data block in the immutable chain of blocks, in response to determining that the second entity is unrecognizable as a trusted entity.
