Only the deal list was an accident, and even that ended up photographed and posted online.
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.
