Hotspot scanning method and electronic device
Embodiments of the present invention provide a hotspot scanning method and an electronic device. Whether a condition of initiating a hidden hotspot scanning is met is first determined.

Signal processing device, imaging device, and signal processing method
Posture information corresponding to a line of an input image is calculated. Then, a first virtual line, which is a line in a line direction of the input image for which the posture information calculated is common, is rotated according to the posture information to obtain a second virtual line on the output image. For each pixel of the output image, a corresponding second virtual line is calculated, and posture information is obtained on the basis of the corresponding second virtual line. Then, for coordinates of each pixel of the output image, the reference coordinates on the input image corresponding to the pixel coordinates is calculated using the associated posture information. By cutting out the output image from the input image on the basis of the reference pixel, highly accurate distortion correction can be realized even in a case where the camera posture differs depending on the line. |

SIEM system and methods for exfiltrating event data
Embodiments provide for a security information and event management (SIEM) system utilizing distributed agents that can intelligently traverse a network to exfiltrate data in an efficient and secure manner. A plurality of agent devices can dynamically learn behavioral patterns and/or service capabilities of other agent devices in the networking environment, and select optimal routes for exfiltrating event data from within the network. The agent devices can independently, selectively, or collectively pre-process event data for purposes of detecting a suspect event from within the network. When a suspect event is detected, agent devices can select a target device based on the learned service capabilities and networking environment, and communicate the pre-processed event data to the target device. The pre-processed event data is thus traversed through the network along an optimal route until it is exfiltrated from the network and stored on a remote server device for storage and further analysis. |

Suspending security violating-database client connections in a database protection system
A database protection system (DPS) is augmented to enable efficient handling of security-violating database client connections. To this end, when the DPS determines to suspend a suspect database client connection several actions are taken. The DPS drops the request and sends a database protocol-specific message to the database server; upon receiving an acknowledgment, the DPS closes the associated transport layer connection mechanism The DPS then initiates an interaction with the client, preferably an exchange of periodic messages (e.g., keep-alive messages) configured to maintain the client in a suspended state. While in this state, the client does not detect any problem with the application or the connection and thus does not try to reconnect to the database server. The DPS then performs an additional assessment/investigation of the violation even as the connection remains open, but suspended. Further action is then taken depending on the results of this evaluation. |

Classical implementation of quantum entanglement in datacenter network design
Quantum mechanics provides several features useful for datacenter networking. The no cloning theorem, which states that it is impossible to mate a duplicate of an arbitrary, unknown quantum state, can be used to detect eavesdroppers. Entanglement allows two parties to have common knowledge of a shared state.These properties are being used today for quantum key exchange and quantum computing, but they are currently too expensive for general use. Fortunately, we can use classical mechanisms to get a close enough approximation of these quantum properties to solve some important problems in distributed computing.Nothing we describe here is quantum mechanical. Rather, we show that it is possible to use classical mechanisms to emulate some properties of quantum mechanics, which enable us to address interesting problems in distributed computing. The engineering insight, is that we can get closer to achieving these properties than might be expected through conventional thinking. The key to obtaining the properties we desire is to make the inherently asynchronous system temporarily locally synchronous for the operations we need.In this patent, we describe how to classically emulate the parts of the no cloning theorem and entanglement that we need for datacenter networking. We then demonstrate how those approximations to quantum behavior can be used to solve important problems in distributed computing, such as ‘exactly-once’ semantics in an environment where failures occur and can be healed without applications needing to know. |

Multi-unicast discovery of devices on a network
Client and server devices identify each other over a LAN or similar network through a series of unicasts.

Method of fabricating a semiconductor device having reduced contact resistance
Implementations of the present disclosure generally relate to methods for forming a transistor. More specifically, implementations described herein generally relate to methods for forming a source/drain contact. In one implementation, the method includes forming a trench in a dielectric material to expose a source/drain region of a transistor, performing a pre-clean process on the exposed source/drain region, forming a doped semiconductor layer on the source/drain region by an epitaxial deposition process, and fill the trench with a conductor. The doped semiconductor layer has a lower electrical resistance than the source/drain region due to a higher dopant concentration in the doped semiconductor layer. As a result, the contact resistance of the source/drain contact is reduced. |
