摘要： A method and system are described. The method includes determining, in a development phase of a software service, whether the software service complies with a first policy in response to a request. The method also monitors, in at least one of a testing phase or a production phase of the software service, whether operation of the software service complies with a second policy. Based on the determining and the monitoring, an indication of a service vulnerability is generated in response to the software service failing to comply with the first policy in the development phase or failing to comply with the second policy in the at least one of the testing phase or the production phase.

摘要： Methods, systems, and storage media for augmenting a video are disclosed. Exemplary implementations may: receive a selection of an effect; receive user-generated content comprising video data and audio data; detect a characteristic of the audio data comprising at least a volume and/or a pitch of the audio data during a period of time; determine a series of numeric values based on the characteristic of the audio data during the period of time, individual numeric values of the series of numeric values being correlated with an amplitude of the volume and/or pitch at a discrete point within the period of time; and augment at least one of the video data and/or the audio data to include the effect based on the series of numeric values at discrete points in time within the period of time.

摘要： Exemplary embodiments relate to the application of media effects to visual data such as a video. A coordinated activity protocol is provided for synchronizing interactive effects and experiences across multiple devices. The protocol allows effects to be initiated and coordinated on multiple devices via a real-time communications (RTC) channel. Messages may be exchanged to cooperatively initiate the effect, and (once initiated) generic data may be exchanged via application programming interface (API) calls. Accordingly, the system is both data-type and platform agnostic, allowing effects developers to define how data will be interpreted. In some embodiments, higher-level services may be provided to exchange data of predefined types (e.g., for common activities such as turn negotiations, turn yielding, scorekeeping, leadership elections, etc.).

摘要： The present disclosure relates to systems, non-transitory computer-readable media, and methods for accurately, flexibly, and efficiently broadcasting public combined live video streams from multiple participant devices, which change over the course of the live broadcast, as well as generating dynamic user interfaces that streamline adding, removing, and swapping participant devices from the public combined live video stream. In particular, a live video streaming system facilitates compositing live video streams from multiple participant devices into a public combined live video stream within a digital room before broadcasting the public combined live video stream to viewer devices. In addition, the live video stream smoothly and efficiently transitions new participant devices from a digital waiting room to the public combined live video stream as well as switches current participant devices from the public combined live video stream to a digital waiting room, all while maintaining live video stream of the participant devices.

摘要： In one embodiment, a method includes receiving an input for a machine-learning model configured to detect a plurality of predetermined features, the machine-learning model including at least a first neural network configured to detect a first subset of the plurality of predetermined features and a second neural network configured to detect a second subset of the plurality of predetermined features, generating a detection result by processing the input using the first neural network, determining that the input includes a feature in the first subset of the plurality of predetermined features based on the detection result and one or more detection criteria, and outputting the detection result as an output of the machine-learning model without using the second neural network to process the input in response to the determination.

摘要： Techniques for scam detection and prevention are described. In one embodiment, an apparatus may comprise an interaction processing component operative to generate a scam message example repository; submit the scam message example repository to a natural-language machine learning component; and receive a scam message model from the natural-language machine learning component in response to submitting the scam message example repository; an interaction monitoring component operative to monitor a plurality of messaging interactions with a messaging system based on the scam message model; and determine a suspected scam messaging interaction of the plurality of messaging interactions; and a scam action component operative to perform a suspected scam messaging action with the messaging system in response to determining the suspected scam messaging interaction. Other embodiments are described and claimed.

摘要： The present disclosure is directed toward systems and methods for ranking media effects. For example, systems and methods described herein enable a user to select and apply one or more media effects to a media communication such as a digital photograph or video. Systems and methods described herein identify and rank media effects based on characteristics associated with the user and the user's client-computing device. Furthermore, systems and methods described herein automatically present the top-ranked media effects to the user such that the user can easily select and apply one or more media effects that are tailored specifically to the user.

摘要： The present disclosure relates to systems, methods, and non-transitory computer readable storage media for implementing a scalable, secure, efficient, and adaptable distributed digital ledger transaction network. Indeed, the disclosed systems can reduce storage and processing requirements, improve security of implementing computing devices and underlying digital assets, accommodate a wide variety of different digital programs (or “smart contracts”), and scale to accommodate billions of users and associated digital transactions. For example, the disclosed systems can utilize a host of features that improve storage, account/address management, digital transaction execution, consensus, and synchronization processes. The disclosed systems can also utilize a new programming language that improves efficiency and security of the distributed digital ledger transaction network.
