Runtime detection of database protocol metadata anomalies in database client connections
A database protection system (DPS) detects anomalies in real time without reliance on discrete security rules, instead relying on a machine learning-based approach. In particular, a Bayesian machine learning model is trained on a set of database protocol metadata (DPM) that the system collects during its runtime operation. Typically, a set of DPM parameters is protocol-specific. The approach herein presumes that DPM parameters are not independent, and that their conditional dependencies (as observed from the database connections) can be leveraged for anomaly detection. To that end, the machine learning model is trained to detect dominant (repeating) patterns of connection DPM parameters. Once trained, the model is then instantiated in the DPS and used to facilitate anomaly detection by identifying connections that do not conform to these patterns, i.e. that represent unusual connection DPM parameters. |

Deep packet inspection indication for a mobile CDN
Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network. The base stations perform deep packet inspection of those packets where flags have been set and forward other packets on to the rest of the relevant backhaul of the mobile network. After deep packet inspection, the base stations either route the packet to the cache server via an established connection or propagate the flag in an extension header to another network node for routing to the cache server. The resulting content is returned to the UE with the source address of the originally intended destination instead of the cache server, rendering the process transparent to the end user. |

Dynamic rolling seventy of illness score for a critically ill patient
A system and method for creating and presenting a rolling severity of illness acuity score are comprised of two phases. The first phase analyzes historical physiologic and clinical data from a hospital's EMR system and discovers data patterns that presage a deleterious outcome. These data patterns are stored in a first database. Once these patterns have been revealed, the second phase involves embedding these patterns into a hospital's EMR, collecting data on new patients in near-real time, matching up this data against the patterns uncovered in Phase One, and producing a score based on how many of these deleterious patterns a patient is exhibiting. This score is updated continuously, weighting the current value higher than previous scores. If this rolling score surpasses a specific value, an alert is generated. The alert, in one example a color-coded signal, is then sent to a mobile device or tablet of the clinicians caring for the patient. |

Personal customized guidance for treating patients
Approaches presented herein enable treating a medical condition via individual customized cognitive guidance. More specifically, a current interactive and customized diagnosis object (ICDO) comprising a treatment schedule for a patient is generated by combining a set of previous ICDOs from the patient, wherein each ICDO has a structure which defines elements that are used to diagnose a symptom and match the patient with a treatment. A status of the patient is monitored in real time via an internet of things network to detect an actual event of the patient differing from the treatment schedule. In real time, the treatment schedule is modified responsive to the differing event by adjusting the current ICDO by exchanging one element of the treatment plan for a new element according to a learned set of rules to compensate for the differing event. This modified treatment schedule is provided to the patient in real time. |
