MediaPost: ClearSight Launches Targeting Platform Tying IP Addresses To Offline Data
“The start-up ClearSight Interactive on Monday launched a new behavioral targeting platform that is already raising eyebrows of privacy advocates. …ClearSight obtains users’ IP addresses from publishers, who themselves gather it from users when they register. Some of those IP addresses change regularly, or are from work addresses or public places, but others persist and can be tied to users’ homes, ClearSight CEO Tom Alison says.”
