Digital ad industry accused of huge data breach
The Irish Council for Civil Liberties is suing a branch of the Interactive Advertising Bureau (IAB) and others over what it describes as “the world’s largest data breach”.
The case brought by Johnny Ryan centres on the data shared between ad brokers and other firms while ad space is being auctioned as a site loads.
There is a debate about the volume of data gathered about people in order to target digital ads, although this form of revenue is what currently keeps most internet services free to use. But Mr Ryan argues that most people using online services are not aware of the amount of data that is shared about them, and with whom.
