Asymmetric co-operative queue management for messages
Improved techniques for responding to a server that is overwhelmed with messages are disclosed herein. Messages may initially be placed in an “incoming” queue. Once accepted by the server for processing, a corresponding message may be placed in an accepted queue, and an indication is generated that the message will be processed.

Also, computing resources are allocated to the incoming queue until the messages in the incoming queue have been processed (or meet another condition). Once the incoming queue is empty or meets another condition, resources are allocated to the accepted queue. Once the number of messages in the accepted queue meets or falls below a second threshold, new messages are allowed again into the incoming queue. |

Blockchain recordation of device usage
Data verification in federate learning is faster and simpler. As artificial intelligence grows in usage, data verification is needed to prove custody and/or control. Electronic data representing an original version of training data may be hashed to generate one or more digital signatures. The digital signatures may then be incorporated into one or more blockchains for historical documentation. Any auditor may then quickly verify and/or reproduce the training data using the digital signatures. For example, a current version of the training data may be hashed and compared to the digital signatures generated from the current version of the training data. If the digital signatures match, then the training data has not changed since its creation. However, if the digital signatures do not match, then the training data has changed since its creation. The auditor may thus flag the training data for additional investigation and scrutiny. |
