"Cern does not condone this type of spoof, which can give rise to misunderstandings about the scientific nature of our work".
"Killjoy," who wrote this spoof which can be found on the Dr. Laura Parody Pages (www.geocities.com/SoHo/Studios/7141/ laura.htm), took a similar tack: Caller: Uh, O.K.... Well, my wife and I have been married for fourtee Dr. Laura: You're having marital problems, aren't you, Phil?
It is likely that hand-held attacks introduce synchronized shaking of the face and spoofing medium which can be observed as excessive relative motion in the view and facial region if the distance between the display medium and the camera is relatively short.
However, when longer video sequences are explored, we are more likely to observe other specific dynamic events, such as different facial motion patterns (including eye blinking, lip movements and facial expression changes) or sudden characteristic reflections of planar spoofing media which can be used for differentiating real faces from fake ones.
While I wouldn't suggest reverting to SMS-based verification, which can be spoofed by attackers, there is a good alternative two-factor authentication service out there called Authy.
Not surprisingly, the from address (which can be easily spoofed) changes much more often and is used as linking feature in only 46% of cluster formations.
The attacks can be launched by a very weak MitM attacker, which can only eavesdrop occasionally and spoof packets (a Weakling in the Middle (WitM)).
The virtual network model is composed of three layers: routing layers, firewall, and shared networks, which can prevent VMs from sniffing and spoofing.
However, challenge-response authentication is not effective against man-in-the-middle (MitM) adversaries (Figure 1), which can inspect the challenges sent within the requests, and craft spoofed responses with valid challenge values.
That makes ECGs more secure than, say, fingerprints, which can be recovered from nearly anything that has been touched.The second part of cloning is replication or "spoofing", in the jargon.
