Abstract

A computer implemented method for determining an origin of indication information in a networked connection between a client device and a server, comprising: receiving, at the server, the indication information of the client device, determining a client-server value based on a transmission time of a connection signal transmitted between the client device and the server, transmitting a tracing signal addressed to the indication information via a particular router in the networked connection between the client device and the server, determining a tracing value based on a transmission time of the tracing signal to the particular router, establishing whether the indication information originates from an intermediate connection in the networked connection or from the client device by comparing a difference value with a threshold value, the difference value being based on the client-server value and tracing value.
