Definitions

  • the invention relates to a method for presence detection and/or event registration at a location or in a spatial area by means of information transmission from a stationary short-range radio module to at least one mobile short-range radio module, wherein the stationary short-range radio module emits multiple beacon messages.
  • the invention further relates to a system for presence detection and/or event registration at a location or in a spatial area by means of information transmission between a stationary short-range radio module and at least one mobile short-range radio module, the system comprising the stationary short-range radio module and the mobile short-range Radio module includes, wherein the stationary short-range radio module is configured such that multiple beacon messages are sent.
  • the invention further relates to a stationary short-range radio module or mobile short-range radio module for use in a system according to the invention.
  • the invention relates to a computer program comprising instructions that can be used to carry out the steps of a method according to the invention, and a computer-readable medium, provided for storing a computer program, or a data carrier signal, provided for transmission of a computer program, the computer-readable medium or the data carrier signal computer program according to the invention stores or transmits.
  • the detection of a local or spatial presence is desirable in many contexts, for example for the automated tracking of infections, such as corona or SARS-Cov2 infections, via smartphone app or for applications in logistics that require automatic registration or presence detection of goods in certain areas, rooms, ships, trains, Trucks or other vehicles require or where automatic registration or presence detection is desirable.
  • infections such as corona or SARS-Cov2 infections
  • smartphone app for applications in logistics that require automatic registration or presence detection of goods in certain areas, rooms, ships, trains, Trucks or other vehicles require or where automatic registration or presence detection is desirable.
  • retrospective contact tracing means that beyond the mere contact tracing of an infected person, it is also asked where this person was or could have been infected. This creates the possibility of also finding other people in the same cluster who were infected in the past, who may be actively contagious at the current search time and who may have already formed unrecognized chains of infection. This allows more (e.g. up to twice the number or more) chains of infection to be broken than through purely forward contact tracing.
  • Retrospective contact tracing can be done using cluster diaries, for example; however, this requires a comparatively large amount of time, attention and manual interaction.
  • Applications such as the Corona-Warn-App (Release 2.0) or the Luca app offer event registration via a QR code scan process. Such an event registration also enables retrospective contact tracing - especially for the purposes of pandemic control, e.g Corona Warn App) or must be scanned by the organizer (with the Luca App).
  • the object of the invention is to provide a method for presence detection and/or event registration at a location or in a spatial area by means of information transmission from a stationary short-range radio module to at least one mobile short-range radio module, with it being transmitted by sending several beacon messages through the stationary short-range radio module is possible to effect the presence detection and/or the event registration in a simple manner and in particular automatically or automatically by sending out a ServiceSet identity information item assigned to the stationary short-range radio module and using the mobile short-range radio module (or in particular a plurality of mobile short-range radio modules) is received.
  • the present invention it is advantageously possible for presence detection and/or event registration to be possible in a comparatively simple and fully automated manner, ie at least potentially without any user interaction, in that - as part of the ServiceSet identity information - the identity information related to the location or the spatial area or the event (hereinafter also referred to as token or token information) is sent out by the stationary short-range radio module and received by the mobile short-range radio module.
  • the mobile short-range radio module Due to the presence as part of the mobile short-range radio module, the software module or the application, it is advantageously possible according to the invention that due to the receipt of the identity information (token or token information) related to the location or the spatial area or the event, the mobile short-range radio module recognizes this information as identity information (token or token information) related to the location or the spatial area or the event.
  • identity information token or token information

  • Such an automated transmission of the identity information related to the location or the spatial area or the event therefore requires essentially no additional effort compared to the devices that are usually available and thus fulfills a convenience function (both for the participating Persons (customers) as well as for the organizer) as well as an acceleration of the processes at the entrance:
  • a convenience function both for the participating Persons (customers) as well as for the organizer
  • an acceleration of the processes at the entrance For the inventive presence detection or event registration, the customer or the organizer does not have to do anything more than an activated application or app (i.e. a software module or an application, e.g . the Corona-Warn-App) as well as an active WLAN functionality, both on the part of the organizer and on the part of the customer.
  • sources of error in a code scanning process that would otherwise have to be carried out are also avoided, such as forgetting to scan or the code scanning failing.
  • QR codes codes to be scanned
  • an easy-to-perform misuse of codes to be scanned can be avoided: Codes, in particular QR codes, can easily be distributed physically or online and the event registration can thus be misused. Copying and disseminating the transmitted identity information (or token or WLAN token) is also possible, but requires significantly more effort.
  • Another advantage of the method according to the invention is an increased level of data protection, because an event organizer does not receive any information about the identity of his customers or participants, which is not the case with the Luca app, for example.
  • a presence detection or event registration is also possible in everyday places where people can be in large numbers or at a comparatively small distance, in particular on or in public or quasi-public spaces such as a bus or a train compartment or other public or private means of transport, such as a taxi or the like. It is thus advantageously possible according to the invention that - for example - different buses and different train compartments are each provided with individual identity information (or a WLAN token) relating to the location or the spatial area or the event, whereby a warning is sent to all persons at the same time in the same public stayed in a room with an infected person (e.g. same train compartment) can be informed via the Corona Warn App.
  • the comfort function of the fully automated registration is particularly important, since manual repeated scanning of different QR codes would be quite cumbersome, especially in frequently frequented places.
