A closer look
Historically, if you wanted a cloud server to calculate your taxes, you had to decrypt the data first, exposing it to hackers. Microsoft SEAL uses homomorphic encryption, which allows a computer to perform mathematical operations on ciphertext. The server blind-crunches the gibberish and spits out an encrypted result. When you download and decrypt that result, it's perfectly accurate. The catch? Compiling these blindfolded operations is computationally brutal.
