Google will release an open source encryption tool to keep data set private

According to Wired, Google will release an open source encryption tool called Private Join and Compute. It helps to join numeric columns from different data sets to calculate the sum, count, or average of encrypted and unreadable data throughout the mathematical process. Only the results of the calculation can be decrypted and viewed by all parties – this means that you can only get results, not data that you do not own. The tool's encryption principles date back to the 1970s and 1990s, but Google has re-used and updated them to work with today's more powerful and flexible processors.
