Abstract: A processor-implemented method improves security in a blockchain network of devices, which supports a blockchain, by protecting security, privacy, financial fairness, and secure transfer of identity assets. An identity asset provider device creates an identity asset related to an entity. The identity asset provider also creates a provider key, which is composed of multiple bits, and which is needed to decrypt an encrypted version of the identity asset. The identity asset provider device transmits the provider key bit-by-bit to an identity asset consumer device. A price for the provider key depends on how many bits have been transmitted to the identity asset consumer device.

Abstract: A first information comprising an identification of an encryption algorithm supported by a first component from the first component of a software defined network (SDN) is received at a controller of the SDN. A set of policies and a set of encryption algorithms are sent to the first component. A policy determines a cryptographic operation applicable to a path in the SDN between the first component and a second component of the SDN. The first component comprises an originating point of the path and the second component comprises a destination point of the path.

Abstract: Techniques to manage remote events are described. An apparatus may comprise a processor circuit and a remote event application arranged for execution by the processor circuit. The remote event application may be operative to manage remote event notifications for a publisher entity and a subscriber entity. The remote event application may comprise, among other elements, an event monitor component operative to receive an external event notification message with a publisher entity event for the publisher entity. The event monitor component may select a custom event receiver component associated with the publisher entity from among multiple custom event receiver components, and send the external event notification message to the selected custom event receiver component. The custom event receiver component may implement custom business logic, such as code callouts designed for specific application programs or system programs. Other embodiments are described and claimed.

Abstract: Malicious activity data is obtained, that is indicative of attempted attacks on a computing system. Clusters of targets are identified and it is determined whether the malicious activity preferentially targets one cluster of targets over other. Also, low prevalence attacks are identified and it is determined whether a low prevalence attack has a high concentration in one or more of the target clusters. If the malicious activity either preferentially targets a cluster, or a low prevalence attack has a high concentration in a cluster, then the attack is identified as a targeted attack, so that remediation steps can be taken.

Abstract: The state of a system is determined in which data sets are generated that include a plurality of data instances representing states of one or more components of a computer system. The data instances generated by one or more data set sources that are configured to output a data instance in response to a trigger associated with the one or more components. The data instances are normalized by the application of one or more rules. The data instances from individual data set sources are separately collated to generate groups of time-specific collated data instances. State types may be assigned to each of the collated data instance groups. Distributions of state-types across the groups may be determined and a list of infrequent state-types may be generated based on the determined distributions of state-types across the groups.

Abstract: An approach for enhancing user communication with a chatbot is provided. In an embodiment, a communication from a user using a chatbot application is received. One or more intents related to the user communication are identified, with each intent having a respective confidence score. Further, any number of attributes related to the user communication are extracted. If multiple viable intents are found (e.g., intents having a confidence score exceeding a predefined threshold), then relationships between the extracted attributes are derived to establish a context. Based on the context, a disambiguation question is generated to clarify an actual intent of the user.

Abstract: Integrated circuits including selectable vias are disclosed. The techniques are particularly well-suited to back end of line (BEOL) processes. In accordance with some embodiments, a selectable via includes a vertically-oriented thin film transistor structure having a wrap around gate, which can be used to effectively select (or deselect) the selectable via ad hoc. When a selectable via is selected, a signal is allowed to pass through the selectable via. Conversely, when the selectable via is not selected, a signal is not allowed to pass through the selectable via. The selectable characteristic of the selectable via allows multiple vias to share a global interconnect. The global interconnect can be connected to any number of selectable vias, as well as standard vias.

Abstract: The present disclosure relates to methods and systems for implementing redundancy in memory controllers. The disclosed systems and methods utilize a row of memory blocks, such that each memory block in the row is associated with an independent media unit. Failures of the media units are not correlated, and therefore, a failure in one unit does not affect the data stored in the other units. Parity information associated with the data stored in the memory blocks is stored in a separate memory block. If the data in a single memory block has been corrupted, the data stored in the remaining memory blocks and the parity information is used to retrieve the corrupted data.

Abstract: Systems herein allow a student to share media with other students in a classroom with the permission of a teacher. The student can send a sharing request to a management server with a sender student device. The management server can identify a teacher device and send the sharing request to the teacher device for approval. When the request is granted, the student device can supply an address local to the sender device, from which the media will stream. The management server can send the address and an authentication token to other recipient student devices. The management server can further lock the recipient student devices into the sharing location to ensure that each student device will stream the media. At the request of the teacher device or the sender student device, the streaming can end.
