In the application, the characteristic code of the virus APK can be accurately and effectively extracted, so as to facilitate improvement of efficiency and accuracy of identification of the virus APK and a variation thereof, thereby improving the security of an APK application.

Abstract: Systems and methods are provided for data exchange in voice communication. For example, a first request message is sent to a server for playing background music in voice communication; an authorization granted by the server to play background music separately from the voice communication is received; and upon reception of a play instruction from a user, the background music is played and an identifier of the background music is sent to the server. The server broadcasts the background music to one or more clients based on at least information associated with the identifier of the background music.

Abstract: A method operable in a security device cluster having a plurality of security devices each configured to receive respective data flows. The method includes receiving a first segment of a flow at a first security device of the plurality of security devices, sending the first segment of the flow toward a destination node without the first security device of the plurality of security devices asserting ownership over the flow, receiving, from the destination node, a second segment of the flow at a second security device of the plurality of security devices, the second segment of the flow being responsive to the first segment, asserting, by the second security device of the plurality of security devices, ownership over the flow, and forwarding, from the first security device, packets of the flow subsequently received by the first security device to the second security device.

Abstract: A method for measuring thickness or defect depth by pulsed infrared thermal wave technology is described. The method includes heating a measured object by pulsed heating devices, and at the same time, obtaining a thermal image sequence on the surface of the measured object by an infrared thermography device, and storing the thermal image sequence in a general-purpose memory. The method also includes multiplying a temperature-time curve at every point of the thermal image sequence by a corresponding time, thereby obtaining a new curve. The method also includes calculating a first-order differential and obtaining a peak time thereof. The method also includes use of one or more formulas to thereby determine the thickness or the defect depth of the measured object.

Abstract: An example method for facilitating hierarchical clustering in a geographically dispersed network environment is provided and includes receiving a packet at one of a plurality of adaptive security appliance (ASA) units in one of a plurality of ASA clusters in a cluster domain of a network environment, identifying the packet as matching an inter-data center live traffic profile, identifying a target ASA cluster in the plurality of ASA clusters in the cluster domain, querying a domain director in the target ASA cluster for a flow owner, and if the flow owner is identified by the domain director, forwarding the packet to the flow owner in the target cluster, and if the flow owner is not identified by the domain director, and the domain director includes a flow state for a flow to which the packet belongs, designating the ASA unit as the flow owner.

Abstract: A computer implemented method of executing applications in a cloud server system is presented. The method comprises receiving a file identifier from a client device. The method also comprises receiving a file associated with the file identifier from a first server. Further, the method comprises accessing an application associated with the file from memory of the cloud server. Also, the method comprises executing by the cloud server the application using the file received from the first server. Finally, the method comprises streaming results from the executing the application as a video stream destined for the client device.

Abstract: Techniques are presented herein for optimizing and load balancing network traffic exchanged between devices in a network environment. At a first device in a cluster of devices in a network, a packet is received from a second device in the cluster. The packet comprises identifier information that is assigned to the first device. The identifier information is reassigned to the second device in the cluster such that subsequent packets with the identifier information are sent directly to the second device. A mapping table is updated to indicate that the identifier information is reassigned to the second device.

Abstract: A method for summarizing a document is provided. A concept is detected for each sentence in said document. Relevance measures between the sentences are computed according to the detected concepts. And then a concept-aware graph is constructed, wherein a node in said graph represents a sentence in the document and an edge between two nodes represents a relevance measure between these two sentences.

Abstract: A method is provided in one example and includes receiving a request message from a first network element using an out-of-band control link. The request message includes a request to bundle a first port associated with the first network element into a channel group associated with a cluster. The cluster includes a plurality of clustered network elements. The method further includes determining a status of the first port with respect to the channel group, and sending a reply message to the first network element using the out-of-band control link. The reply message indicates the determined status of the first port of the first network element.

Abstract: The subject disclosure is directed towards a technology for efficiently emulating program code that is protected by one or more various code virtualization techniques to detect the presence of malware. An emulation engine emulates a program containing a mix of native code, custom (e.g., virtualized obfuscated) code, and at least one emulator and/or interpreter that understands the custom code, by building a custom emulation component that is built by detecting and analyzing the internal emulator or interpreter. The custom emulation component may access a translation table built from the analysis, and also may simplify a plurality of instructions in the program into a lesser number of instructions in an intermediate language used for emulation.
