摘要： Methods and devices for determining whether a mobile device has been compromised. The mobile device has a managed portion of memory and an unmanaged portion of memory, a managed profile and an unmanaged profile, and the managed profile includes files stored in the managed portion of memory and the unmanaged profile includes files stored in the unmanaged portion of memory. The managed profile is governed by a device policy set by a remote administrator. File tree structure information for the managed profile of the mobile device is obtained that details at least a portion of a tree-based structure of folders and files in the managed portion of memory. It is determined from the file tree structure information that the mobile device has been compromised and, based on that determination, an action is taken

摘要： A method and system for tracking an asset in an indoor facility. The method includes receiving, from a first mobile device, an asset tracking tag collision report, the asset tracking tag collision report including a tag identifier of an asset tracking tag associated with an asset; determining a new location of the asset based on the received asset tracking tag collision report; updating an asset location database to indicate the new location of the asset; and, in response to determining the new location of the asset, transmitting an instruction message to a mobile device to cause the mobile device to direct the asset tracking tag to cease broadcasting the wireless signal. The method and system use crowd-sourcing to determine a new location of an asset that has moved in an indoor facility.

摘要： Methods and devices for determining whether a mobile device has been compromised. The mobile device has a managed portion of memory and an unmanaged portion of memory, a managed profile and an unmanaged profile, and the managed profile includes files stored in the managed portion of memory and the unmanaged profile includes files stored in the unmanaged portion of memory. The managed profile is governed by a device policy set by a remote administrator. File tree structure information for the unmanaged profile of the mobile device is obtained that details at least a portion of a tree-based structure of folders and files in the unmanaged portion of memory. It is determined from the file tree structure information that the mobile device has been compromised and, based on that determination, an action is taken.

摘要： Methods and systems for detecting a privacy violation in an image file. A policy to be used by a master imaging application is obtained and a file system is monitored for a digital image modified by a monitored imaging application. It is then determined that the digital image file includes at least some content in violation of a defined setting for the master imaging application and, based on the determination that the digital image file includes at least some content in violation of the defined setting for the master imaging application, taking an action.

摘要： Methods and devices for determining whether a mobile device has been compromised. File tree structure information for the mobile device is obtained that details at least a portion of a tree-based structure of folders and files in a portion of memory. The file tree structure information is analyzed to determine that the mobile device has been compromised, has not been compromised, or might be compromised. Based on determining that the mobile device might be compromised, the mobile device is instructed to execute a restricted action. If the restricted action occurs on the mobile device then it is determined that the mobile device has been compromised. Based on that determination, an action is taken.
