The entry appears to be the first time that the term “ad tech” has appeared in a request for information, contract solicitation, or contract justification posted by ICE in the Federal Registry, according to searches by WIRED. In an unsigned statement emailed to WIRED, ICE stressed that the filing was solely for information and planning purposes. ICE has also previously purchased products that provide mobile location data, which is sometimes among the information provided by companies that buy and sell information collected for online advertising. Ad tech data can include details about the device and apps a person is using, where they are located, and their browsing activity, among other information. ICE has purchased commercial location data obtained from Webloc, a tool sold by the company Penlink.
