Abstract: Devices, computer-readable media, and methods for selecting a type of transmission for an immersive visual stream based upon a latency estimate. For instance, a processing system including at least one processor may obtain a latency estimate for an immersive visual stream, determine whether the latency estimate exceeds a latency threshold for selecting a type of transmission for the immersive visual stream, and select the type of transmission for the immersive visual stream from among a field of view restricted type of transmission and a field of view plus out of scene type of transmission based upon the determining. When the latency estimate is determined to not exceed the latency threshold, the field of view restricted type of transmission is selected. When the latency estimate is determined to exceed the latency threshold, the field of view plus out of scene type of transmission is selected.

Abstract: Concepts and technologies disclosed herein are directed to proxy-based database encryption. According to one aspect, a database encryption proxy system can receive, from a database client, input of a Structured Query Language (“SQL”) statement and data to create an encrypted database table. At least a portion of the data is marked with an encrypted identifier to identify which data is to be encrypted by the proxy-based database. The database encryption proxy system can generate a random string for the portion of the data that is marked with the encrypted identifier. The database encryption proxy system can convert the SQL statement into a converted SQL statement that includes the random string in place of the portion of the data marked with the encrypted identifier and can send the converted SQL statement to a cloud database service that is configured to create the encrypted database table based upon the converted SQL statement.
