OTFcreds: Activity 1.3 Develop strategies for mitigating faulty measurements

[jbonisteel]

Based on the previous heuristics for detecting if OONI measurements are inconsistent, we will create a set of strategies for what to do when we have determined that a measurement is “bad” (by some definition of “bad”).

These strategies might involve (in the most “light” case) annotating relevant measurements with a flag indicating that it should not be trusted, while in more extreme cases, we might even decide to reject the submission altogether to prevent storing bad data at all.

This activity will be led by the OONI team (CTO, Research Engineer and Backend Engineer). It will also involve the cryptographer substantially more as we need to consider how the new anonymous credential system will interface with the strategies and decisions associated with dealing with faulty measurements. As the anonymous credential system evolves, we intend to perform a couple of different iterations in this area of work.

Output: specification document outlining the strategies for mitigating faulty measurements.
