摘要： A system and method to ensure trustworthiness of a remote service provided by a service provider. The method includes monitoring runtime dependencies invoked during execution of a service transaction associated with the remote service, the service transaction being requested by a service requester. The method further includes determining whether a deviation exists between the runtime dependencies and a trusted list of dependencies associated with the remote service. The method also includes blocking execution of the service transaction based on determining that the deviation between the runtime dependencies and the trusted list of dependencies exists.

摘要： Devices, systems, and methods are disclosed which utilize lightweight agents on a mobile device to detect message-based attacks. In exemplary configurations, the lightweight agents are included as contacts on the mobile device addressed to an agent server on a network. A malware onboard the mobile device, intending to propagate, unknowingly addresses the lightweight agents, sending messages to the agent server. The agent server analyzes the messages received from the mobile device of the deployed lightweight agents. The agent server then generates attack signatures for the malware. Using malware propagation models, the system estimates how many active mobile devices are infected as well as the total number of infected mobile devices in the network. By understanding the malware propagation, the service provider can decide how to deploy a mitigation plan on crucial locations. In further configurations, the mechanism may be used to detect message and email attacks on other devices.

摘要： Devices, systems, and methods are disclosed which leverage an agent that resides in a mobile communication device to detect Proximity based Mobile Malware Propagation (PMMP). The agent injects one or several trigger network connections in the candidate connection list. These connections appear as legitimate networks and devices. However, the triggers connect to an agent server on a service provider's network. Essentially, the method is based on the assumption that malware lacks the intelligence to differentiate the trigger network connection from a normal one. Therefore, by attempting to connect through the trigger network connection, the malware reveals itself. The system helps collect the malware signature within a short period of time after the malware outbreak in local areas, and such attacks typically bypass network based security inspection in the network.
摘要翻译：公开了利用驻留在移动通信设备中的代理来检测基于接近度的移动恶意软件传播（PMMP）的设备，系统和方法。代理在候选连接列表中注入一个或多个触发网络连接。这些连接显示为合法的网络和设备。但是，触发器连接到服务提供商网络上的代理服务器。本质上，该方法是基于这样的假设：恶意软件缺乏将触发网络连接与正常触发网络连接区分开来的智能。因此，通过尝试通过触发网络连接进行连接，恶意软件显示出来。系统在本地恶意软件爆发之后的短时间内帮助收集恶意软件签名，这种攻击通常会绕过网络中的网络安全检查。

摘要： A machine-learning engine is disclosed that is configured to recognize and learn behaviors, as well as to identify and distinguish between normal and abnormal behavior within a scene, by analyzing movements and/or activities (or absence of such) over time. The machine-learning engine may be configured to evaluate a sequence of primitive events and associated kinematic data generated for an object depicted in a sequence of video frames and a related vector representation. The vector representation is generated from a primitive event symbol stream and a phase space symbol stream, and the streams describe actions of the objects depicted in the sequence of video frames.

摘要： Embodiments of the present invention provide a method and a system for analyzing and learning behavior based on an acquired stream of video frames. Objects depicted in the stream are determined based on an analysis of the video frames. Each object may have a corresponding search model used to track an object's motion frame-to-frame. Classes of the objects are determined and semantic representations of the objects are generated. The semantic representations are used to determine objects' behaviors and to learn about behaviors occurring in an environment depicted by the acquired video streams. This way, the system learns rapidly and in real-time normal and abnormal behaviors for any environment by analyzing movements or activities or absence of such in the environment and identifies and predicts abnormal and suspicious behavior based on what has been learned.

摘要： Modulator devices are selectably adjustable between at least two states, wherein the transmission and/or reflection of particular wavelengths of light are modified. Certain modulator devices are substantially uniformly adjustable over a wide range of wavelengths, including visible and infrared wavelengths. Other modulator devices are adjustable over visible wavelengths without significantly affecting infrared wavelengths. In addition, the modulator devices may be used in conjunction with fixed thin film reflective structures.
