Privacy protection for participatory sensing system
First Claim
1. A user equipment, comprising:
- a sensor arrangement comprising at least one sensor for sensing data associated with an environment surrounding the user equipment, the sensed data having at least one attribute;
at least one processor; and
at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to at least;
generate a pseudonym in association with sensed data;
calculate a unique value based upon the pseudonym using a first algorithm;
generate an electronic communication data structure comprising the unique value and the sensed data;
send the electronic communication data structure to a server;
receive from the server, in response to the server receiving the electronic communication data structure, an electronic certificate, wherein the electronic certificate is calculated at the server, based at least in part on the unique value and the at least one attribute of the sensed data, using a second algorithm; and
send, from the user equipment to the certification center via a secure channel, an electronic communication data structure comprising at least the pseudonym and the certificate;
receive, from the certification center, at the user equipment, an electronic communication data structure comprising an electronic reward associated with the sensed data, the electronic reward generated by the certification center based on the unique value generated by the user equipment and the certificate calculated at the server;
wherein the certification center is internal or external to the server.

Abstract
Provided is a method that may be used for privacy protection. The method comprises: generating a pseudonym at a user equipment in association with sensed data; calculating a unique value based upon the pseudonym using a first algorithm; sending the unique value and the sensed data to a server; receiving from the server a certificate, wherein the certificate is calculated based at least in part on the unique value using a second algorithm; and sending at least the pseudonym and the certificate to a certification center via a secure channel, for obtaining a reward associated with the sensed data; wherein the certification center is internal or external to the server. By this method, a user'"'"'s identify may be protected.

6. An apparatus, comprising:
-
at least one processor; and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least; receive, from a user equipment and in an electronic communication data structure, a unique value and sensed data from the user equipment, the sensed data associated with an environment surrounding the user equipment, the sensed data having at least one attribute and the unique value calculated at the user equipment using a first algorithm based upon a pseudonym generated by the user equipment, the pseudonym associated with the sensed data; calculate an electronic certificate, based at least in part on the unique value and the at least one attribute of the sensed data, using a second algorithm; and send the certificate, in an electronic communication data structure, to the user equipment so that the certificate may be forwarded to a certification center by the user equipment, in an electronic communication data structure and via a secure channel, for obtaining a reward associated with the sensed data, the reward generated by a certification center based on the unique value generated by the user equipment and the certificate; wherein the certification center is internal or external to the apparatus. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
at least one processor; and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to at least; receive, from a user equipment, an electronic communication data structure, including at least a pseudonym and a certificate, and via a secure channel, the pseudonym generated by the user equipment and associated with sensed data obtained by the user equipment; calculate a unique value using a first algorithm based upon the pseudonym; calculate at least one reference value based at least in part on the unique value using a second algorithm; compare the at least one reference value with the received certificate; and if the at least one reference value matches the received certificate, confirm validity of the received certificate so that the user equipment may obtain an electronic reward associated with sensed data, the electronic reward based on the unique value generated by the user equipment and the certificate; wherein the apparatus is internal or external to a server. - View Dependent Claims (14, 15, 16)
