In data publishing, the owner delegates the role of satisfying user
queries to a third-party publisher. As the servers of the publisher
may be untrusted or susceptible to attacks, we cannot assume that
they would always process queries correctly, hence there is a need
for users to authenticate their query answers. This book introduces
various notions that the research community has studied for
defining the correctness of a query answer. In particular, it is
important to guarantee the completeness, authenticity and
minimality of the answer, as well as its freshness. We present
authentication mechanisms for a wide variety of queries in the
context of relational and spatial databases, text retrieval, and
data streams. We also explain the cryptographic protocols from
which the authentication mechanisms derive their security
properties. Table of Contents: Introduction / Cryptography
Foundation / Relational Queries / Spatial Queries / Text Search
Queries / Data Streams / Conclusion
