Privacy Goals Achieved


Privacy goals achieved

In our research, development, and 2017 patent application, we believe we have fully achieved each of the following goals. The overall purpose is to make life extremely difficult for hackers of messages and files. You are invited to judge the success and the quality of these endeavors!

  1. Destroy all meaningful patterns in data (in technical terms, "high entropy" results).
  2. Resist brute force attacks. Make attacks difficult with MarpX Good Privacy, make attacks 438 times more difficult with MarpX Better Privacy, and render brute force attacks impossible ("computationally infeasible") with Extreme Encryption™.
  3. Blindfold the hacker.
  4. Maximize efficiency of encryption and decryption.
  5. Add research capability (search and text data mining) to encrypted content.
  6. Achieve full scalability in the light of the quantum computing threat.
