Abstract Database outsourcing to semi-honest servers raises concerns
against the confidentiality of sensitive information. To hide such information,
an existing approach splits data among two supposedly mutually
isolated servers by means of fragmentation and encryption. This approach
is modelled logic-orientedly and then proved to be confidentiality
preserving, even if an attacker employs some restricted but nevertheless
versatile class of a priori knowledge to draw inferences. Finally, a method
to compute a secure fragmentation schema is developed.
