Color correction for video communications using display content color information
Video presence systems are described that detect an area of interest (e.g., facial region) within captured image data and analyze the area of interest using known color information of the content currently being presented by a display, along with measured ambient light color information from a color sensor, to determine whether the area of interest (e.g., face) is currently illuminated by the display or whether the AOI is not affected by the display and instead only illuminated by the ambient light. Upon determining that the display casts color shade on the AOI, the video presence system pre-processes the image data of the detected area of interest to correct the color back to skin color under ambient light prior to performing general white balance correction. |

Automated encryption degradation detection, reporting and remediation
Communication security is an ongoing problem. Over time, various protocols have been used and then replaced due to insufficient protection. For example, some client/server web communication used to rely on Secure Socket Layers (SSL) to protect communication, but was replaced with a more secure Transport Layer Security (TLS) protocol. TLS itself has undergone several revisions, and TLS 1.0 is now considered not secure. TLS and other protocols provide backwards compatibility, so while a higher security level is desired, communication may fallback to an undesirable level, e.g., TLS 1.0, if required by either communication endpoint. An intermediary to communication with an organization may capture data to facilitate analyzing it to determine what caused a fallback, and to decide if and how to remediate it. Remediation may vary depending on, for example, whether the cause was from within the organization, or external, such as from a client. |

Early credit return for credit-based flow control
A device allocates buffer space for storing data received from another device. The other device has a credit balance corresponding to the amount of buffer space. A sending device reduces its number of credits by a cost of a packet and sends the packet. To ensure that the buffer does not overflow, the sending device spends a credit for each entry in the buffer that could be consumed by the sent data packet. When received data is added to the buffer without consuming a new entry, a response packet that returns a credit is sent to the sending device before the data is read from the buffer. Thus, the sending device is enabled to continue sending data without waiting for the buffer to be read, enabling the communication between the two devices to make more efficient use of the buffer. |
