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.

39. An apparatus, comprising:
-
a sensor arrangement comprising at least one sensor for sensing data; 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; generate a pseudonym in association with sensed data; calculate a unique value based upon the pseudonym using a first algorithm; send the unique value and the sensed data to a server; receive from the server a certificate, wherein the certificate is calculated at the server based at least in part on the unique value using a second algorithm; and send 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. - View Dependent Claims (40, 41, 42, 43)

44. 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; receive a unique value and sensed data from a user equipment, wherein the unique value is calculated at the user equipment using a first algorithm based upon a pseudonym generated by the user equipment; calculate a certificate based at least in part on the unique value using a second algorithm; and send the certificate to the user equipment so that the certificate may be forwarded to a certification center for obtaining a reward associated with the sensed data; wherein the certification center is internal or external to the apparatus. - View Dependent Claims (45, 46, 47, 48, 49, 50)

51. 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; receive at least a pseudonym and a certificate via a secure channel from a 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 a reward associated with sensed data; wherein the apparatus is internal or external to a server. - View Dependent Claims (52, 53, 54)
