Abstract
In an Internet interface device such as a gateway managing a local network, a processor obtains a packet received from a device via a local network interface. The processor can determine whether or not the packet originates from a device in the local network deemed to be part of a particular group. The processor can also determine if the packet is addressed to an internet domain for which it stores identifying information in memory. In this case, the processor inspects the packet in search of a cookie. In case no cookie is found, the packet is output as is; if a cookie is found, the processor modifies cookie information in the packet by inserting a cookie specific to the Internet interface device, which results in a modified packet that then is output through the internet interface. Using the original cookie and the added cookie, it is possible to link cookies sent from different devices in the local network.
