Abstract

Privacy is becoming a pervasive issue, as nowadays information is gathered by all kind of information systems. In this paper we introduce a method for database protection in the case that the data under consideration is expressed in terms of time series. We propose the use of microaggregation for this purpose and extend standard microaggregation so that it works for this kind of data.
