Chairman: Martin Kissel,  Telefónica


Responsible for developing standards that support the requirements of national and international law for the Lawful Interception and retained data of electronic communications.

Lawful Interception (LI) and Retained Data play a crucial role in helping law enforcement agencies to combat terrorism and serious criminal activity. They therefore form a key part of the infrastructure supporting electronic transactions and are crucial in the growth and development of the Information Society.

The providers of public telecommunications networks and services are legally required to make available to law enforcement authorities information from their retained data which is necessary for the authorities to be able to monitor telecommunications traffic as part of criminal investigations.

For achieved and ongoing work on Lawful Interception and Retained Data published by ETSI TC LI and other ETSI Technical Bodies, as well as a list of all related publication, please refer to the ETSI Security White Paper.
