Unintentional electronic traces: connection data
Traceability of electronic exchanges and the law

The involuntary traces that an Internet user can leave on networks are manifold. Identification most often takes place without reference to traditional identification elements (identity card, photograph, fingerprint, etc.). It involves recognizing a specific person, or at least the IP address of his or her computer (or router), as he or she navigates the network and exchanges electronic messages (see Box 4). These traces are referred to as connection data, a topical issue that has been the focus of attention of legislators at both Community and national levels.
