Abstract: This invention relates to a data system that anonymizes personalized event data, by receiving the personalized event data containing an encrypted personal identifier and determining whether an entry exists for the encrypted personal identifier in a key database. The encrypted personal identifier may be associated with a system identifier that uniquely identifies the encrypted personal identifier and is uniquely associated to one system identifier. If no entry is detected in the key database for the received encrypted personal identifier, then a new entry for the key database is generated in which the received encrypted personal identifier is uniquely associated to a new system identifier.

Abstract: The invention relates to the problem of exposure of passengers and crew members of aircraft to cosmic radiation. To reduce the radiation exposure, a safety belt is described, which has a protective effect against cosmic radiation, wherein the belt is combined with a cosmic radiation absorbing material or such material is incorporated into the belt, and wherein the cosmic radiation absorbing material contains boron or a boron-containing material. A corresponding method for the production of a safety belt for passengers and crew members of aircraft is also described. Thereby, an effective means to protect the passengers and crew members of aircraft against cosmic radiation is provided, which can be implemented without affecting air traffic and without serious economic consequences for commercial aviation.
