Ariadne provides precise localization of customers in shops.
It enables cost reduction and revenue increase, through the interactive optimization of infrastructure via digital businesses tools.


Ariadne senses signals generated by smartphones for detecting their location. It is up to two orders of magnitude more accurate than GPS. It does not require a smartphone application or a network connection. It respects the privacy of users, by enabling state-of-the-art anonymity. It enables shop owners to identify:

  • the most visited products/areas,
  • the frequency of visited customers,
  • the number of potential customers or
  • the attracted attention of products in the shop window.

It guides shop owners to redesign their shops following data-driven approaches, (e.g. AB test).

Use Cases

Commuter Navigation Application

Ariadne can route you through the public transportation of a city, while it indicates the nearest train compartment and the nearest subway exit to your destination. Ariadne enables people to share their location data in order to enhance the experience of other commuters, with systems such as real-time monitoring of the train location. Finally, Ariadne provides complete indoor navigation, routing, and localization, in every subway station.

Ariadne provides tools that can enable physical businesses to analyze customer information following data-driven approaches borrowed by digital businesses.

For example, airports can identify bottlenecks of customers and use this information to redesign their infrastructure in a less congested way. Malls can adopt prices of shops based on customer flow. Shop owners can optimize their shop window guided by the number and the duration that people stay there. Public transportation providers can identify future routes or passenger congestion that can cause an increase in itinerary intervals. Additional, most physical businesses will be enabled to quantify the effect of promotions. Museums and exhibition centers will identify optimal routes for exhibits and will replace or reward exhibits accordingly.

Ariadne aims to introduce all the advantages of the digital era to the physical world. Physical business will benefit from tools such as artificial intelligence, machine learning and process mining, worlds which are unknown to them yet.

Landmark Mining with Ariadne Application

Ariadne enables indoor localization and WiFi and BLE mapping through a crowdsourcing approach that relies on a gamified approach. More specifically, people are walking freely inside buildings and while they are collecting tokens in a shape of golden start, they stream useful information about the received signal strength of the building, which enables us to generate an accurate radio map. This radio map can later be used for precise indoor localization.

Competitive Advantage

Ariadne is a state-of-the-art framework that provides precise localization indoors and outdoors. It makes use of advanced artificial intelligence algorithms, developed at the Technical University of Munich, for precise and anonymous tracking of passengers, enabling airports and other mobility related organizations to make the best use of their infrastructure for minimizing congestion, and hence dwell time, while maximizes passenger satisfaction and experience.

Ariadne does not require users do not need to install any application on their phones or being connected at any wireless network. Ariadne monitors users in real time in the greatest accuracy possible. It has been benchmarked by the IEEE IPIN 2018 and found to be better than leaders at the field of localization, such as Google, IBM, and Samsung.

Ariadne is the first ever framework that applies mathematically proven state-of-the-art anonymization methods in real time for stream data, respecting the privacy of the passengers and hence achieving GDPR compliance.

Ariadne has been built upon two core-patented ideas that enable the precise localization in off-the-shelf devices, reducing the cost, while increasing the accuracy by one order of magnitude.

Ariadne is the first framework that makes use of state-of-the-art block-chain infrastructure, called Tangle, and developed by IOTA, in Germany, for transparent data streaming and real-time data purchase by algorithms acting as bidding agents.

Ariadne has been adopted by leading global airports, such as Heathrow and Glasgow, while it has been also used in train stations by leading railway companies such as Deutsche Bahn.
