Abstract: Disclosed is a method of building a customized deep learning (DL) stack classifier to detect organization sensitive data in images, referred to as image-borne organization sensitive documents, and protecting against loss of the image-borne organization sensitive documents, including distributing a trained feature map extractor stack, with stored parameters, configured to allow the organization to extract from image-borne organization sensitive documents, feature maps that are used to generate updated DL stacks and to save non invertible feature maps derived from the images, and ground truth labels for the image. Also included is receiving organization-specific examples including the non-invertible feature maps extracted from the organization-sensitive documents and the ground truth labels and using the received organization-specific examples to update a customer-specific DL stack classifier. Further included is sending the customer-specific DL stack classifier to the organization.

Abstract: Techniques for selecting portions of audio tracks for content item inclusion are described. For example, a social networking system may receive, from an audio producer, an audio track. In some examples, the social networking system may, using a machine-learned model, determine a first portion of the audio track having a change of frequency over time, and provide the first portion of the audio track to a first user for inclusion in a content item. In some cases, the social networking system may receive a selection of a second portion of the audio track. Based on the selection of the second portion of the audio track, the social networking system may modify the parameters of the machine-learned model to provide the second portion of the audio track to a second user.

Abstract: A method of authenticating a client device to access a user account stored on a remote server includes creating the user account based on a blockchain address of a blockchain wallet, transmitting a login request for logging into the user account from the client device to the remote server, and transmitting a random challenge from the remote server to the client device when the remote server receives the transmitted login request. The random challenge is associated with the user account and no other user account. The method further includes signing the random challenge with the client device, the signature based on a private key of the blockchain wallet, transmitting the signed random challenge and the blockchain address to the remote server, and verifying that the signed random challenge corresponds to the transmitted random challenge with the remote server using a public key of the blockchain wallet and the random challenge.

Abstract: Systems and methods include obtaining file identifiers associated with files in production data; obtaining lab data from one or more public repositories of malware samples based on the file identifiers for the production data; and utilizing the lab data for training a machine learning process for classifying malware in the production data. The obtaining file identifiers can be based on monitoring of users associated with the files, and only the file identifiers are maintained based on the monitoring. The lab data can include samples from the one or more public repositories matching the corresponding file identifiers for the production data. The lab data can include samples from the one or more public repositories that have features closely related to features of the production data.

Abstract: A multipath data transmission method and device are provided, where a multipath proxy client and a multipath proxy gateway establish at least two multipath data subflows based on a first internet protocol (IP) address, and perform multipath data subflow data transmission. Based on the first IP address for establishing the at least two multipath data subflows between the multipath proxy client and the multipath proxy gateway, the multipath proxy gateway establishes a TCP connection to and performs TCP-based data transmission with an application server to be accessed by the multipath proxy client. MPTCP-based multipath data transmission based on IP address information of the multipath proxy client is implemented through proxy of the multipath proxy client and the multipath proxy gateway.
