Rather than adopting the common approach of filtering out seemingly fraudulent clicks, we consider instead an affirmative approach that only accepts legitimate clicks, namely those validated through client authentication.

for security often means that standard human-computer-interaction
approaches cannot be directly applied. An important usability goal
for authentication systems is to support users in selecting better
