Psychographic device fingerprinting

A system for automatically updating a database of psychographic device fingerprints, comprising:

• a computing device in data communication with a network;
• and
• memory accessible by the computing device and storing a psychographic device fingerprint generating program configured to automatically update an existing psychographic device fingerprint stored in the database which, when executed, performs steps for:
• (a) detecting reception at the computing device of media content delivered via the network;
• (b) reading one or more device elements from the memory;
• (c) reading a geographic indicator from the memory;
• (d) determining a timing parameter associated with reception of the media content at the computing device;
• (e) reading a content indicator identifying the media content;
• (f) deriving from the one or more device elements, the geographic indicator, the timing parameter, and the content indicator, a bit stream comprising a psychographic device fingerprint, the bit stream uniquely identifying the computing device and one or more users of the computing device;
• (g) comparing the psychographic device fingerprint to fingerprints stored in the database;
• (h) detecting a partial match between the psychographic device fingerprint and one of the stored fingerprints, wherein the partial match comprises a part of the bit stream of the psychographic device fingerprint;
• and
• (i) updating the one stored fingerprint that was partially matched by replacing it in the database with the psychographic device fingerprint.
