Abstract: By intercepting a natural language communication of a protected party, the communication is monitored, wherein the protected party is a human being. Within the monitored communication using a natural language processing engine, a natural language interaction between the protected party and a second party is detected. To determine an interaction pattern, the natural language interaction is analyzed. The interaction pattern includes data derived from the monitored communication, metadata of the protected party, and metadata of the second party. Using the interaction pattern and an interaction behavior model, an adverse result of the natural language interaction is predicted, wherein the adverse result comprises an economic loss to the protected party. By notifying the protected party, the predicted adverse result is intercepted.

Abstract: A method, apparatus, system, and computer program product for training a global machine learning model. A hierarchical structure for nodes in which the global machine learning model is located at a primary node in the hierarchical structure is identified. Authorized nodes in which local data is authorized for use in training in the authorized nodes for a local training of local machine learning models are determined. The machine learning models in the authorized nodes are trained using the local data in the authorized nodes to generate local model updates to weights in the local machine learning models. The local model updates to the weights are propagated upward in the hierarchical structure to the global machine learning model, wherein a node receiving local model updates to the weights from nodes from a lower level aggregates the weights in the local model updates received from the nodes in the lower level.

Abstract: In an approach for anonymizing data, a processor receives a mixed-type dataset with at least two relational attributes and at least one textual attribute. A processor runs the mixed-type dataset through a text annotator to discover a set of personally identifiable information (PII). A processor creates a set of ghost attributes to add to the mixed-type dataset. A processor anonymizes data of the at least two relational attributes and the set of ghost attributes. A processor replaces each PII in the textual attribute with the corresponding anonymized data in the at least two relational attributes or the set of ghost attributes to create an anonymized mixed-type dataset. A processor removes the set of ghost attributes from the anonymized mixed-type dataset. A processor shuffles records of the anonymized mixed-type dataset to create a shuffled anonymized mixed-type dataset. A processor outputs the shuffled anonymized mixed-type dataset.

Abstract: A method, system, and computer program product for detecting data tampering with resilient watermarking is provided. The method accesses a first relational data set on a data repository. The first relational data set includes a plurality of data elements. The first relational data set is sorted to generate a first sorted list and a second sorted list of the plurality of data elements. The method generates a watermark from the first sorted list and the second sorted list. The watermark contains a hash corresponding to the first sorted list and the second sorted list of the plurality of data elements. In response to an access request for the first relational data set, the method verifies an integrity of the first relational data set based on the watermark.

Abstract: A computer-implemented method for training a global federated learning model using an aggregator server includes training multiple local models at respective local nodes. Each local node selects a set of attributes from its training dataset for training its local model. Each local node generates an anonymized training dataset by using a syntactic anonymization method, and by selecting quasi-identifying attributes from training attributes, and generalizing the quasi-identifying attributes using a syntactic algorithm. Further, each local node computes a syntactic mapping based on equivalence classes produced in the anonymized training dataset. The aggregator server computes a union of mappings received from all the local nodes. Further, federated learning includes training the global federated learning model by iteratively sending, by the local nodes to the aggregator server, parameter updates computed over the local models.
