Collaborative Indoor Positioning Systems (CIPSs) have recently received considerable attention, mainly because they address some existing limitations of traditional Indoor Positioning Systems (IPSs). In CIPSs, Bluetooth Low Energy (BLE) can be used to exchange positioning data and provide information (the Received
Signal Strength Indicator (RSSI)) to establish the relative distance between the actors. The collaborative models exploit the position of actors and the relative position among them to allow positioning to external actors
or improve the accuracy of the existing actors. However, the traditional protocols (e.g., iBeacon) are not yet
ready for providing sufficient privacy protection. This paper deals with privacy-enhancing technologies and
their application in CIPS. In particular, we focus on cryptographic schemes which allow the verification of
users without their identification, so-called Anonymous Attribute-based Credential (ABC) schemes. As the
main contribution, we present a cryptographic scheme that allows security and privacy-friendly sharing of
location information sent through BLE advertising packets. In order to demonstrate the practicality of our
scheme, we also present the results from our implementation and benchmarks on different devices. [-]
