Method for determining proximity between mobile devices, method for managing a database, computer program product, and mobile device

Abstract

A method for determining proximity between a first mobile device (111) of a first user (121) and a second mobile device (112) of a second user (122) is provided. The method includes: searching, by the second mobile device (112), for short-range advertising broadcasts sent by mobile devices (111, 113) of other users (121, 123); receiving, by the second mobile device (112), among the short-range advertising broadcasts at least a first short-range advertising broadcast sent by the first mobile device (111), the first short-range advertising broadcast encoding a universally unique identifier (UUID) and a first user identifier being unique for the first user (121) of the first mobile device (111); decoding, by the second mobile device (112), the first short-range advertising broadcast received from the first mobile device (111) to obtain the first user identifier; checking, by the second mobile device (112), whether a received from the first mobile device (111) pairing entry in a local database stored in the second mobile device (112) exists for the first user identifier, and if the pairing entry exists, initiating, by the second mobile device (112), a user notification process to notify, by the second mobile device (112), the second user (122) that the first user (121) is located in proximity.
