Abstract: Methods and systems for using a distributed ledger to record bot mitigation test results and enable servers to determine a bot mitigation score for a remote device based on previously recorded test results associated with the remote device. The server may detect a trigger for bot mitigation in association with a remote device, obtain identifying data regarding the remote device and search a distributed ledger using the identifying data to locate one or more test results stored in records on the distributed ledger containing the identifying data. It may then determine a bot likelihood score based on the one or more test results, compare the bot likelihood score to a threshold and, in response to the comparison, execute a mitigation action.

Abstract: The present disclosure involves systems, software, and computer implemented methods for presenting recommendations for suggested activities. One example method includes receiving a first signal from a device that includes a current context of the device that includes location information for the device. The device is associated with a particular profile. A preferred language associated with the device is determined from the profile. The profile is analyzed to determine a contextual activity preference associated with the device. A repository of establishment information is searched to identify an activity that matches the current context associated with the device and the contextual activity preference. An activity description of the identified activity is translated from a foreign language to the preferred language to create a translated activity description. A second signal is transmitted to the device that includes the translated activity description for presentation at the device.
