More and more personal information is available digitally, both collected by organizations and published by individuals. People may attempt to protect their privacy by avoiding to provide uniquely identifying information and by providing different information in different places; however, in many cases, such profiles can still be de-anonymised. Techniques from the record linkage literature can be used for pair-wise linking of databases, and for cross-correlation based on these pair-wise results. However, the privacy implications of these techniques in the on-line setting are not clear: existing experiments depend on quasi-identifiers and do not focus on cross-correlation.
