Abstract

A method in a first device for anonymously delivering data to a part that has initiated a task is provided. The first device and the part initiating a task are participants in opportunistic sensing. The method comprises creating a data sample and encrypting the data sample with a public key of the task initiating part. After communicating the protected sample to one or more intermediate devices, one of the one or more intermediate devices delivers the protected sample to the task initiating part, such that the task initiating part does not know the identity of the first device. The task initiating device only know the identity of the one of the one or more intermediate devices that delivered the protected sample to the task initiating part, wherein the intermediate devices are participants in the opportunistic sensing.
