Cryptographic Control for Privacy in Data Collection and Processing

Abstract
Internet users are frequently prompted by a form that requires them to
enter private information and is accompanied with a ``privacy
statement'' describing the purpose of collection and the type of data
usage that will be carried out. How does a user know that the collector
will adhere to its privacy statements? Moreover how is it possible to
allow marketing, selling or out-sourcing of such data while ensuring
that not only the original data collecting entity but also any
subsequent holder will not violate the terms of the original agreement?
This talk will address the above fundamental problem by introducing a
framework called contract-based computing whose aim is to bridge the
need for privacy to the need for data collection, marketing and
processing, using cryptographic control. Using such framework we show
how contract-based computing can be performed efficiently for a number
of data processing functionalities that include the extraction of sets,
multi-sets, statistics and correlation information from user data.
