Abstract: The concepts and technologies disclosed herein are directed to providing a split ledger for securing extended reality (“XR”) environments. According to one aspect, an XR server computer can create an XR environment. The XR server computer can cause a passed ledger to be populated with an environment ID associated with the XR environment. The XR server computer can cause a hash ledger to be populated with a first hash of the environment ID. The XR server computer can register a user for participating in the XR environment and can cause the passed ledger to be populated with a user-created block associated with the user. The XR server computer can cause the hash ledger to be further populated with a second hash of the user-created block. The XR server computer can allow a user avatar associated with the user to join the XR environment.

Abstract: An extended reality (“XR”) server computer can identify a plurality of XR objects present in an XR environment. The XR server computer can determine an owner for an XR object of the plurality of XR objects. The XR server computer can visually differentiate, based on the owner, the extended reality object from other extended reality objects of the plurality of extended reality objects. The XR environment can be a virtual reality (“VR”) environment, an augmented reality (“AR”) environment, or a mixed reality environment. The XR server computer can create an ownership chain for the owner. The XR server computer can assign the XR object and at least one additional XR object to the ownership chain. The XR server computer can receive a request to transfer ownership of the XR object and can commit the transfer from a source ownership chain to a destination ownership chain.

Abstract: The concepts and technologies disclosed herein are directed to on-demand trusted extended reality (“XR”) environments. According to one aspect disclosed herein, a user device can create a trusted list identifying at least one trusted XR environment. The user device can connect to an untrusted XR server computer and can allow a user avatar associated with a user to enter an untrusted XR environment provided by the untrusted XR server. The user device can detect an event for which a trusted XR environment is desired. The user device can select the trusted XR environment to handle the event. The user device can select the trusted XR environment from the trusted list. The user device can instruct the untrusted XR server computer to teleport the user avatar from the untrusted XR environment to the trusted XR environment.

Abstract: Providing and using a user login protection service can include detecting, during a login creation process, input that indicates that a computing device has opted-in for protection for a login being created. During the login creation process, the login can be stored at a first data storage location, the login including an address that identifies a location of a distributed ledger and a password, and a reset password at a second data storage location comprising a secure data storage device. In response to detecting an attempt to log in to the third party device to access the resource, a value associated with the distributed ledger can be obtained, the value indicating a status of a trigger condition associated with the login. If the value is zero, the attempt to log in can be allowed to proceed. If the value is one, the attempt to log in can be blocked.

Abstract: Enabling machine-to-machine communication for digital assistants can include initiating a call with a called device, generating audio stream data having a first instance of audio and a first spoken command, which can be provided to the called device. A second instance of audio stream data can be received from the called device, can include a second spoken command, and can be analyzed to determine if it includes assistant signature data. If the second instance of audio stream data includes the assistant signature data, the devices can switch to machine-to-machine communications.

Abstract: Providing and using an activity logging service can include registering an activity logging service with a hash ledger storage service that can store a hash ledger that represents an activity log for an entity, and registering an observer device with the activity logging service. The observer device can provide event data to the activity logging service, and the event data can describe an event associated with the entity. The event data can be obtained from the observer device and a block that represents the event can be generated. A block can be added to the activity log, and a hash of a portion of the activity log can be generated and sent to the hash ledger storage service. The hash ledger storage service can be configured to append the hash of the portion of the activity log to the hash ledger that represents the activity log for the entity.

A time period associated with the monitoring can be identified. The monitoring of the user device can be triggered, where the monitoring can include obtaining video associated with the user device that is streamed to an edge device, wherein the video can be analyzed to determine if a threat is detected. If a determination is made that the threat is not detected, termination of the monitoring and deletion of the video can be triggered. If a determination is made that the threat is detected, delivery of an alert to another device can be triggered.

Abstract: A content management system provides content item sharing and synchronization for users of client devices. The content items stored by content management system can include any type of data, such as digital data, media, data files and databases, source and object code, recordings, and any other type of data or file. A collaboration content item management system allows users to create, edit and share collaboration content items among a plurality of other users. Collaboration content items are files that a users can create and edit using a collaboration content items editor, and are composed of collaboration content item elements. The content management system and collaboration content item management system provide functionality for linking content items with collaboration content items to keep the contents of each synchronized with one another and allow for access of the same content from both systems.

Abstract: A collaborative content management system allows users to access collaborative content items. When a client device accesses a shared collaborative content item, the client device displays a portion of the collaborative content item that falls within a viewport. The client application generates a notification count of notification events associated with content that is contained in the collaborative content item and positioned below the viewport, and the client device displays the notification count in a graphical element adjacent to a bottom viewport edge. A similar process generates a second notification count of the notification events associated with content positioned above the viewport and displays a graphical element with the second notification count adjacent to the top viewport edge. The user can iteratively select one of the graphical elements to move the content of the collaborative content item to a portion corresponding to the next notification event above or below the viewport.
