Abstract: Systems and methods for identifying which video segment is being displayed on a screen of a television system. The video segment is identified by deriving data from the television signals, the derived data being indicative of the video segment being displayed on file screen. This feature can be used to extract a viewer's reaction (such as changing the channel) to a specific video segment (such as an advertisement) and reporting the extracted information as metrics. The systems and methods may further provide contextually targeted content to the television system. The contextual targeting is based on not only identification of the video segment being displayed, but also a determination concerning the playing time or offset time of the particular portion of the video segment being currently displayed.

Abstract: An autonomous distributed wise area network (AD-WAN) includes several nodes, where each node connects a local area network to an open wide area network, and provides tunnels over the open wide area network to other nodes in the AD-WAN so that computing resources behind each node can communicate as if they were located on a common intranet. Each node has a blockchain wallet and receives updates to a private permissioned blockchain ledger for that AD-WAN. The updates are provided by a control node. Set up, and subsequent change to the AD-WAN are commenced via a customer portal which provides order information to the control node, where the control node processes the order information and generates a blockchain update that informs the affected nodes in the AD-WAN as to what changes are to be made. As a result, the blockchain provides both control plane and order management operation of the AD-WAN.

The repetitions are limited to a pre-defined maximum number or attempts. The fetching attempts may be performed by the client device, by an intermediate device in a non-direct fetching scheme, or a combination thereof. Various fetching schemes may be used sequentially until the content is retrieved.

Abstract: A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The tunnel device is selected based on an attribute, such as IP Geolocation. A tunnel bank server stores a list of available tunnels that may be used, associated with values of various attribute types. The tunnel devices initiate communication with the tunnel bank server, and stays connected to it, for allowing a communication session initiated by the tunnel bank server. Upon receiving a request from a client to a content and for specific attribute types and values, a tunnel is selected by the tunnel bank server, and is used as a tunnel for retrieving the required content from the web server, using standard protocol such as SOCKS, WebSocket or HTTP Proxy. The client only communicates with a super proxy server that manages the content fetching scheme.

Abstract: A method for fetching a content from a web server to a client device is disclosed, using tunnel devices serving as intermediate devices. The client device accesses an acceleration server to receive a list of available tunnel devices. The requested content is partitioned into slices, and the client device sends a request for the slices to the available tunnel devices. The tunnel devices in turn fetch the slices from the data server, and send the slices to the client device, where the content is reconstructed from the received slices. A client device may also serve as a tunnel device, serving as an intermediate device to other client devices. Similarly, a tunnel device may also serve as a client device for fetching content from a data server. The selection of tunnel devices to be used by a client device may be in the acceleration server, in the client device, or in both.

Abstract: A processor establishes time-based file access limits that are concurrently applicable to file access requests associated with a user ID and detects an abnormal file system access pattern to a file system by applying statistical process control to network layer packets communicating file access requests. Applying statistical process control includes comparing a number of file access requests by the user ID observed in an observation interval to file access limits including one based on periodicity of file access requests and/or a second one based on age of accessed files. Based on the comparing, the processor generates an event based on each time-based file access limit that is satisfied, and based on one or more events, detects the abnormal file system access pattern. The processor initiating an action based on detection of the abnormal file system access pattern.

Abstract: Described herein are techniques for facilitating push provisioning of a user payment source into a user's digital wallet without the user having a physical card. The techniques allow an issuer to provide a button in an issuer's mobile application for the user to simply push the button to request that the payment source be imported into the user's digital pay wallet. In this way, the payment source information is “pushed” into the pay wallet. Using push provisioning, the user need not enter any physical card information. The described techniques generate a chain of trust that can be used to ensure that a user, through an issuer and using an encryption gateway, authorizes a token service provider to provision the payment source into the user's digital wallet.
