Abstract: A baseline virtual machine (VM) instance is created within a protected secure environment from a production VM image. The baseline VM instance is a protected clone of a production VM instance created within a deployed environment from the production VM image. VM instance information of the baseline VM instance is collected during a startup process of the baseline VM instance within the protected secure environment. First baseline validity code is generated from the collected VM instance information of the baseline VM instance. VM instance information of the production VM instance is collected during a startup process of the production VM instance within the deployed environment. First production validity code is generated from the collected VM information of the production VM instance. A determination is made as to whether there is an error in the production VM instance by comparing the first baseline validity code and the first production validity code.

Abstract: Approaches for registering and monitoring drones for safety and access control are provided. A computer-implemented method includes: receiving, by a computer device, location data from plural drones via low power, long range wireless transmission; updating, by the computer device, a central registry with the location data; generating, by the computer device, display data based on the location data and a location of a display device; and transmitting, by the computer device, the display data to the display device via a network.

Abstract: In an approach to device authentication, one or more processors receive a security policy comprising at least a first media access control (“mac”) address and a corresponding time period for determining network access for a device. One or more processors receive a second mac address and a corresponding time of connection of the second mac address for authentication of the device. One or more processors determine the second mac address is the first mac address and, responsive to determining the second mac address is the first mac address, one or more processors determine to grant network access to the device based on whether the time of connection of the second mac address is within the time period.

Abstract: A method of transcoding web images. The method comprises determining a mean opinion score (MoS) for a test source digital image, transcoding the test source digital image to a test derived digital image, and determining a MoS for the test derived digital image presented on a standard display. The method further comprises receiving a source digital image by a server computer, where the source digital image is requested by a device for presentation on a target display, transcoding the source digital image to a derived digital image by a transcoding application executed by the server computer, determining an estimated MoS for the derived digital image based on the MoS for the test source digital image, based on the MoS for the test derived digital image, and based on differences between the standard display and the target display, and changing a parameter of the transcoding application based on the estimated MoS.
