Abstract: Systems and methods of authenticating voice data using a ledger (blockchain). Examples include a scalable and seamless system that uses blockchain technologies to distribute trust of a conversation, authenticate persons in a conversation, track their characteristics and also to keep records of conversations. In some examples, smart phones, wearables, and Internet-of-Things (IoT) devices can be used to record and track conversations between individuals. These devices can each be used to create entries for the blockchain or a single device could be used to keep track of the entirety of the conversation. Fuzzy hashing may be used to compare newly created entries with previous entries on the ledger.

Abstract: A neural network having one or more public parts and one or more confidential parts is trained to perform a primary task. A deployment instantiation of the neural network is trained based on optimal performance of the primary task, and based on sub-optimal performance of the primary task conditioned on the confidential parts of the deployment instantiation being inaccessible. An adversary instantiation of the neural network is trained based on optimal performance of the primary task conditioned on the public parts being identical for the deployment instantiation and for the adversary instantiation, and conditioned on the confidential parts of the deployment instantiation being inaccessible. The training of the deployment instantiation and the training of the adversary instantiation are based on a plurality of training data samples, and are performed iteratively by alternating between the training of the deployment instantiation and the training of the adversary instantiation.

Abstract: A system and method for the analysis of log data is presented. The system uses SuperMinHash based locality sensitive hash signatures to describe the similarity between log lines. Signatures are created for incoming log lines and stored in signature indexes. Later similarity queries use those indexes to improve the query performance. The SuperMinHash algorithm uses a two staged approach to determine signature values, one stage uses a first random number to calculate the index of the signature value that is to update. The two staged approach improves the accuracy of the produced similarity estimation data for small sized signatures. The two staged approach may further be used to produce random numbers that are related, e.g. each created random number may be larger than its predecessors. This relation is used to optimize the algorithm by determining and terminating when further created random numbers have no influence on the created signature.

Abstract: A cyber threat intelligence (CTI) gateway device may receive rules for filtering TCP/IP packet communications events that are configured to cause the CTI gateway device to identify communications corresponding to indicators, signatures, and behavioral patterns of network threats. The CTI gateway device may receive packets that compose endpoint-to-endpoint communication events and, for each event, may determine that the event corresponds to criteria specified by a filtering rule. The criteria may correspond to one or more of the network threat indicators, signatures, and behavioral patterns. The CTI gateway may create a log of the threat event and forward the threat event log to a task queue managed by a cyberanalysis workflow application. Human cyberanalysts use the cyberanalysis workflow application to service the task queue by removing the task at the front of the queue, investigating the threat event, and deciding whether the event is a reportable finding that should be reported to the proper authorities.

Abstract: A network security system that analyzes data from network attacks to determine which attacks came from the same attacker, even if the attacker tries to disguise its identity by spreading attacks out over time and attacking from multiple IP addresses. Intrusion detection systems or firewalls may log data for each attack, such as the time of the attack, the type of attack, and the source and target addresses. Embodiments may augment this data with derived attributes that may profile the attacker's behavior. For example, some attackers may spread out attacks over time, but always attack on the same day of the week; some attackers may spread out attacks over different IP addresses, but these addresses may all be in the same country. The original and augmented data may be clustered using an algorithm such as DBSCAN, and each attacker may be identified with one of the resulting clusters.
