I read the article and didn't catch what the criminals are doing with the data. So ransom attacks are a diversion so they can exfiltrate the data quietly. Are they engaging in identity theft? Are they blackmailing people? What exactly are they doing? EDIT: Prior to Snapchat, I envisioned an iOS application that would track the "chain of custody" of images and electronic documents. iOS isn't perfect, but it is one of the more secure platforms for this kind of app. A cloud-based server would manage keys, which would only be available per-use of each document. Is that what protenius is doing? Such a system would provide ample data for detecting fraudulent use of medical records.
