Abstract: A computer-implemented method, system and computer program product for preserving concurrency and asynchronous execution for versioned documents. A versioned document is received to be uploaded onto a platform, such as a blockchain platform, where the metadata of the versioned document includes a first identifier representing a time at which the version of the versioned document came into existence. Furthermore, a second identifier is generated representing a specific state or instance of the versioned document with no relation to a logical order of the instance of the versioned document with respect to other versions of the versioned document. A document record may then be created for the versioned document which includes both identifiers. Such identifiers may be utilized by a distributed application, such as a blockchain application, to handle various types of requests from the users of the client devices while still preserving concurrency and asynchronous execution for versioned documents.

Abstract: According to one embodiment of the present invention, a system masks data objects across a plurality of different data resources. The system comprises a processor configured to include a plurality of service providers to mask the data objects, wherein each service provider corresponds to a different type of data masking for the data objects. An interface provides access to the plurality of service providers from different data-consumers to mask the data objects according to the corresponding types of data masking, wherein resulting masked data maintains relational integrity across the different data resources. Embodiments of the present invention further include a method and computer program product for masking data objects across a plurality of different data resources in substantially the same manners described above.
