Digital provenance is meta-data that describes the ancestry
or history of a digital object. Most work on provenance
focuses on how provenance increases the value of
data to consumers. However, provenance is also valuable
to storage providers. For example, provenance can provide
hints on access patterns, detect anomalous behavior,
and provide enhanced user search capabilities. As
the next generation storage providers, cloud vendors are
in the unique position to capitalize on this opportunity to
incorporate provenance as a fundamental storage system
primitive. To date, cloud offerings have not yet done so.
We provide motivation for providers to treat provenance
as first class data in the cloud and based on our experience
with provenance in a local storage system, suggest
a set of requirements that make provenance feasible and
attractive.
