Abstract: There is provided a method of federated machine learning using at least one processor, the method including: transmitting a current global machine learning model to each of a plurality of data sources; receiving a plurality of training updates from the plurality of data sources, respectively, each of the plurality of training updates being generated by the respective data source in response to the global machine learning model received; and updating the current global machine learning model based on the plurality of training updates received and a plurality of data quality parameters associated with the plurality of data sources, respectively, to generate an updated global machine learning model. There is also provided a corresponding server for federated machine learning.

Abstract: A system is provided, which includes at least one digital object owner client computing device, a trusted server computing device and at least one digital object consumer client computing device. Each of said at least one digital object owner client computing device is configured to transmit a created or amended access permission message to the trusted server computing device. The trusted server computing device is configured to generate, from the created or amended access permission message, at least one personalized access permission message, each of which is uniquely addressed to one of the at least one digital object consumer client computing device. The at least one digital object consumer client computing device is configured to enforce a download, from the trusted server computing device, of the at least one personalized access permission message uniquely addressed to the at least one digital object consumer client computing device.

Abstract: An apparatus, method and computer program for the management of digital information bearing digital signatures is disclosed. The invention includes an apparatus for the management of digital information in a database. This apparatus further includes the means for importing the digital information; means for processing the digital information, wherein the digital information may include at least one digital document, at least one digital signature, at least one public key certificate, at least one archival policy; means for obtaining data from an external server and means for exporting output information from the apparatus, whereby a user when importing the digital information to the apparatus, causes the digital information to be processed thereby generating the output information that is stored in the database.
