Unified intra block copy and inter prediction modes
Innovations in unified intra block copy (“BC”) and inter prediction modes are presented. In some example implementations, bitstream syntax, semantics of syntax elements and many coding/decoding processes for inter prediction mode are reused or slightly modified to enable intra BC prediction for blocks of a frame. For example, to provide intra BC prediction for a current block of a current picture, a motion compensation process applies a motion vector that indicates a displacement within the current picture, with the current picture being used as a reference picture for the motion compensation process. With this unification of syntax, semantics and coding/decoding processes, various coding/decoding tools designed for inter prediction mode, such as advanced motion vector prediction, merge mode and skip mode, can also be applied when intra BC prediction is used, which simplifies implementation of intra BC prediction. |

Stream-based data deduplication with peer node prediction
Stream-based data deduplication is provided in a multi-tenant shared infrastructure but without requiring “paired” endpoints having synchronized data dictionaries. Data objects processed by the dedupe functionality are treated as objects that can be fetched as needed. As such, a decoding peer does not need to maintain a symmetric library for the origin. Rather, if the peer does not have the chunks in cache that it needs, it follows a conventional content delivery network procedure to retrieve them. In this way, if dictionaries between pairs of sending and receiving peers are out-of-sync, relevant sections are then re-synchronized on-demand. The approach does not require that libraries maintained at a particular pair of sender and receiving peers are the same. Rather, the technique enables a peer, in effect, to “backfill” its dictionary on-the-fly. On-the-wire compression techniques are provided to reduce the amount of data transmitted between the peers. |

Detecting web resources spoofing through stylistic fingerprints
A method of detecting deceptive web activity is implemented in an intermediary located between a requesting client device, and a server that hosts a web application. Following a bootstrap phase used to generate a database of information identifying characteristics of clients, the method begins by receiving a page directed to the client from the server. The server injects an invisible DOM element having a set of style properties associated therewith, with one of the set of style properties assigned a random value, to generate a modified page, which is returned to the client. As the client interacts with the modified page, the intermediary tracks the device's styles and uses them to identify the client from information in the database. Once the device is identified, the intermediary then detects whether a spoofing attack has occurred. By leveraging the tracked styles, a spoofing attack on the DOM element's styles may also be detected. |

Determining hop count distribution in a network
Hop counts can be determined in a variety of network segments using packet headers collected at boundaries of the segments. Agents executing on network devices are used to transmit packet header data, including a TTL budget, to a collector server computer. The collector server computer can discern signal (production flows) from noise (traceroutes and probing traffic), detecting packets that are at risk of being dropped due to TTL expiration. Alerts can be generated for packet flows with a dangerously low remaining TTL budget, which are at high risk of expiring due to operational events resulting in traffic temporarily traversing slightly longer paths. Source addresses can be identified for such packet flows and network devices through which the packet flows are traversing can be identified. Hop counts can then be computed for different network segments, such as an Internet segment, a backbone segment and a data center segment. |
