ABSTRACT:
Methods and arrangements are provided for handling, within a communications system comprising a distributed domain (301) and a central domain (303), electronic records that contain predictions of the outcome of a certain incident. Within the distributed domain (301), a multitude of electronic records are generated that contain predictions of the outcome of the incident and are conveyed (305) from the distributed domain (301) to the central domain (303). Each of the electronic records is furnished (304, 401, 502, 902, 1202, 1911), within the distributed domain (301), with a cryptographically protected proof of a certain moment of time associated with the generation of the electronic record. The central domain (303) accepts (306, 1430, 2011) only those of the electronic records conveyed thereto as valid for which the cryptographically protected proof of a certain moment of time associated with the generation of the electronic record shows that said certain moment of time was not later in time than a certain time limit.
