Abstract:
1. A server device for controlling a transaction between the first entity and the second entity, comprising: a receiver for receiving a first message from the first entity, the first message comprising first information related to the transaction, and a second message from the second entity, the second message comprising second information related to the transaction; a matcher for checking whether the first information in the first message and the second information in the second message comprise a predetermined relation to each other; and an output interface for authorizing the transaction, when the first information and the second information comprise a predetermined relation and for rejecting the transaction, when the first information and the second information do not comprise the predetermined relation to each other, wherein the matcher is adapted to perform a check whether a time difference between a reception or generation of the first message and a reception or generation of the second message or a time difference between a generation of an identification code in the first entity and a transmission or reception of the first message or the second message is greater than a predetermined amount of time or not, wherein the output interface is operative to reject a transaction, when the predetermined amount of time is exceeded, wherein each of the first message and the second message comprises a time stamp indicating a generation or a transmission time, and wherein the matcher is operative to perform the check based on the time stamps of the first message and the second message, or wherein the second message comprises a time code generated by the first entity, and wherein the matcher is operative to perform the check by comparing the time code generated by the first entity to a reception time of the second message.
