Abstract: Securely performing file operations. A method includes determining a licensing characteristic assigned to a file. When the licensing characteristic assigned to the file meets or exceeds a predetermined licensing condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the guest operating system. When the licensing characteristic assigned to the file does not meet or exceed the predetermined licensing condition, then the method includes performing the file operation on the file in the guest operating system while preventing the file operation from being performed directly in the host operating system.

Abstract: The techniques described herein enable client APIs to be deployed within isolated computing environments while externally exposing and/or maintaining a log of computing events that the client APIs perform and/or attempt to perform within the isolated computing environments. Generally described, configurations disclosed herein enable audit parameters associated with client application programming interfaces (APIs) to be deployed within an isolated computing environment to generate a log of computing events performed by the client APIs. Ultimately, access to the log of computing events is provided externally to the isolated computing environment without exposing sensitive computing resources (e.g., a host operating system (OS)) to the various client APIs.

The method further includes, for each one of the received sensor signals, performing digital processing on the one or more respective digital values using a respective one of a plurality of processing engines to generate one or more respective processed digital values. The method further includes performing additional processing on the processed digital values.

Abstract: A host operating system running on a computing device monitors resource access by an application running in a container that is isolated from the host operating system. In response to detecting resource access by the application, a security event is generated describing malicious activity that occurs from the accessing the resource. This security event is analyzed to determine a threat level of the malicious activity. If the threat level does not satisfy a threat level threshold, the host operating system allows the application to continue accessing resources and continues to monitor resource access. When the threat level satisfies the threat level threshold, the operating system takes corrective action to prevent the malicious activity from spreading beyond the isolated container. Through the use of security events, the host operating system is protected from even kernel-level attacks without using resources required to run anti-virus software in the isolated container.

Abstract: Anonymous containers are discussed herein. An operating system running on a computing device, also referred to herein as a host operating system running on a host device, prevents an application from accessing personal information (e.g., user information or corporate information) by activating an anonymous container that is isolated from the host operating system. In order to create and activate the anonymous container, a container manager anonymizes the configuration and settings data of the host operating system, and injects the anonymous configuration and settings data into the anonymous container. Such anonymous configuration and settings data may include, by way of example and not limitation, application data, machine configuration data, and user settings data. The host operating system then allows the application to run in the anonymous container.

Abstract: Variety of approaches to provide a copy of a notebook document are described. A copy application programming interface (API) of a productivity service initiates operations to copy a source notebook document upon receiving a request to copy a designated portion of the source notebook document to a destination. In response to the received request, the copy API retrieves serialized data stored in a source section file associated with the designated portion of the source notebook document. The serialized data is provided such that a new portion of a destination notebook document is constructed at the destination based at least in part on the serialized data.

Abstract: Freeform input is not native to several application or document types, but is desired by users as an input mode, especially for collaboration. Systems and methods are therefore provided to enable the insertion of an electronic collaboration workspace that accepts and stores freeform input for use as an object embeddable in various documents. An external host application provides the functionalities needed for freeform input, and the inputs may be committed to the document or stored as a separate document which may be referenced and accessed by multiple users for purposes of collaboration.
