Abstract: The present disclosure relates to a system to evaluate an avatar generated by an avatar generator. The system comprises an evaluation module including an audio evaluation module for evaluating audio features and a video evaluation module for evaluating video features. Evaluation of the avatar includes extracting audio and video features from the avatar and applying a set of evaluation metrics for generating audio and video evaluation scores. The scores are combined to generate a final score. For avatar generator evaluation, audio clip and video clip are provided to the audio evaluation module and video evaluation module, respectively. A set of evaluation metrics is applied for evaluation. Each metric can generate a score. All scores are combined to generate a final evaluation score.

Abstract: The present disclosure relates to an avatar generator to generate an audio-visual avatar specific to an application, such as tutoring. The avatar generator includes a general synthesizer to receive a training dataset. The general synthesizer includes a voice synthesis module and a video synthesis module trained by the training dataset. The avatar generator includes a customized synthesizer consisting of a voice custom synthesis module and a video custom synthesis module trained on the audio-video samples of the target person. The avatar generator further includes a video generator to create an audio-visual avatar and is configured to synthesize a voice clone using an input text, process the voice clone, synthesize a video clone based on the video synthesis module and the video custom synthesis module, and apply the voice clone to the video clone.

Abstract: The present disclosure includes methods and systems for protecting network resources. A method may start, by a processor, copy-on-write snapshotting for modifications to a plurality of files stored on electronic storage. A method may monitor, by the processor, access to objects within a file system associated with the electronic storage for a set of operations. A method may intercept, by the processor, one or more operation of the set of operations for modifying a region of a file in the file system. A method may capture, by the processor, one or more of original contents, modified contents and written contents of the region. A method may end, by the processor, copy-on-write snapshotting. A method may perform malware and/or ransomware analysis on a process performing the modification to the region of the file in the file system.

Abstract: System and method for administration of remote user activities interacting with critical data are used to detect violations of user activities, generate hints in response to each violation or a group of violations, that includes video-based violations, audio-based violation, and display-control-based violations, and to display hints to the administrator in a prioritized manner helping the administrator to react to most critical violations in a proper way. The invention solves a problem of simultaneous monitoring of multiple user interactions with critical data by ranking each violation, each session of interaction and each user.

Abstract: A system and method of anti-malware analysis including iterative techniques that combine static and dynamic analysis of untrusted programs or files. These techniques are used to identify malicious files by iteratively collecting new data for static analysis through dynamic run-time analysis.

Abstract: A method of switching seamlessly at a receiving end is provided for converting a lower quality digital signal to a higher quality digital signal by initiating a real-time sound reconstruction and restoration process on the lower quality signal. The conversion occurs without interruption of the signal and without re-opening a connection to the signal provider.
