collection environment

User session traces which were collected from a large number of free Wi-Fi hotspots in Montreal, Quebec, Canada for six years.

network configuration

WifiDog is composed of the following 2 components: - the gateway is a daemon process that gets installed on every wireless router on a hotspot. - the auth server is a web application that gets installed in a central location. WifiDog enables a new hotspot site to configure the equipment by just plugging it in the existing network and entering the new router password.

Existing networks, such as DSL and cable connections, have proven rather unreliable, so WifiDog makes monitoring easier in the following ways:

• it graphically displays the status and location of each hotspot (see http:\/\/carte.ilesansfil.org\/). - in case of fault, it sends mail to local support resources assigned to that hotspot. - it is completely unaffected by network address translation or firewalls upstream. - finally it does all this without any extra software (VPN, SNMP, etc).

data collection methodology

The ISF team collects user session (i.e., between login and logout) data such as account (user) id, MAC address, login and logout time, hotspot id, and amount of data transferred incoming and outgoing. They also logs content display and click-through, but only for content being displayed on the auth server, and therefore the data are not included in this data set.

sanitization

The ISF team anonymized account id (user_id), connection id (conn_id), user MAC address (user_mac), and hotspot id (node_id). They performed hashing with a different random seed for every value. The code that generated the anonymised data can be found at http:\/\/dev.wifidog.org\/browser\/trunk\/wifidog-auth\/wifidog\/classes\/StatisticReport\/AnonymisedDataExport.php
