Data Aggregation Policy

The primary principles is that any aggregated data released by Edge must be anonymized so that the source of the data cannot be identified from the data by reverse engineering.  This involves:

• having a sufficiently large sample size (number of petrol filling stations); and
• having sufficient diversity of sources so that no source and the approximate data from that source can be identified by reverse engineering; and
• having no source or group of sources which contribute to the data in a way that significantly skews the data (a very large or very small volume outlier).
  ‍

All three criteria must be satisfied for the data to be both meaningful and anonymized, and therefore usable.

EdgePetrol would not expect data to be useful, usable or necessarily anonymized if any one of the above contributes more than twenty five percent (25%) of the sample size or data.
