I created the PrismCipher cryptosystem in response to wholesale data collection by the NSA and the Five Eyes countries, and by companies offering “free” services where the account holder’s data itself is the price of admission.
Whether it’s from a global SaaS company or a nation-state actor, data collection is routinely performed 1) without a warrant, 2) with little judicial oversight, and 3) with no opportunity for redress.
In response, I wanted a solution for the problems of corporate espionage (Google reading my Gmails) and government internet surveillance (NSA PRISM program) while still being able to enjoy the use of popular mainstream services.
PrismCipher for Chrome is the initial implementation as a Chromium browser extension. After all, encrypting your messages and mail before storage or distribution is the only safe and reliable approach.
