Why it matters...
Nine leaks this week, and no two moved the same way: a bundle of strategy papers circulated inside a government, a study a company paid for and kept to itself, an email thread between officials and the governors who report to them, training material written for contractors, an audio recording of a candidate speaking, a memo welcoming a newsroom back for the season, a memo telling another newsroom its jobs were going, and design images of a product that has not been announced.
EchoMark embeds unique, invisible watermarks in documents, emails, images, and screens. When those watermarks are embedded before information goes out, they deter would-be leakers. When something does leak, investigators have the evidence to trace it back to the copy it came from.
