With silent SMS, cell site analysis and IMSI catchers, authorities can pinpoint the location of a mobile device to within a few metres.
Last year, the German Federal Criminal Police sent about 68,000 silent SMS in 33 cases (one of which was a danger aversion case), which is a significant increase compared to preceding years. The Federal Police sent around 48,000 silent text messages in 56 criminal proceedings, which is roughly the average of past years. This is stated in the answer to a parliamentary question by the Left Party in the Bundestag. „Germany: Mobile phones as a tracking bug“ weiterlesen
Procedures according to §§ 100 of the Code of Criminal Procedure (StPO) to determine the whereabouts and identification of mobile phones in Germany
In addition to telecommunications surveillance (§ 100a StPO) and online searches (§ 100b StPO), German police authorities use technical means within the framework of §§ 100 StPO to determine the location of mobile phones. These include the so-called „silent SMS“, IMSI-Catcher and cell site analysis. Customs and the secret services are also partially authorised to perform these tasks. Six-monthly parliamentary inquiries in the Bundestag document that the number of measures for federal authorities has remained at about the same level in recent years. According to the figures of individual states, the investigative methods under Sections 100 of the Code of Criminal Procedure are in some cases used much more frequently there than by federal authorities. Some measures for the localisation of telephone owners are in a grey area and have led to legal adjustments. A ruling by the Federal Court of Justice last year could be the reason why the figures for „silent SMS“ have suddenly fallen sharply. Some federal states are currently merging into „Joint Competence and Service Centres“ in the field of police telecommunications surveillance (GKDZ), which are being set up in Hamburg and Leipzig/Dresden. It is possible that with these centralised GKDZs, the number of measures for telecommunications surveillance within the framework of §§ 100 StPO will increase further. „The tracking bug in your pocket: Mobile phone surveillance in Germany“ weiterlesen
