Abstract: A method of operating a service provider server and a computing device to provide anonymous service access. For the service provider server, the method comprises: receiving a service message from a computing device; and determining whether to send a service response message, and if so sending a service response message. The service message includes a pseudonym associated with the computing device, service data and a signature on the pseudonym generated by either the service provider server or an identity manager. The service response message is broadcast by the service provider server or transmitted to the identity manager.

Abstract: Examples disclosed herein relate to detecting an activity based on time difference metrics. In one implementation, a processor determines metrics related to the differences between the sizes of sets. For example, each set may include time indications that result in the particular integer associated with the set when a modular operation is performed on a difference between the respective time indication and a first time indication. The processor may detect a pattern indicative of an activity based on the metrics and output an indication that the activity is detected.
