It's very weird to call data normalization "encryption". This is just a standard procedure done on most datasets. Encryption implies they've gone to extra processing to make sure you can't figure out what the variables mean.
I think it's either an abuse of the word 'encryption'. That, or they really have done something weird to this dataset. Which will probably make it useless for statistical algorithms. Even normalization destroys a lot of useful information.
- jamez1 10y agoThey only need to go as far as to obfuscate the market data this was derived from, so they don't have to pay exchange licencing fees. It doesn't have to have an exponential time complexity on decryption to qualify as 'encryption'. Multiplying by 2 could be considered homomorphic encryption. You might think encryption means something else and that it's an abuse of the word but unlike the spy novella that you derive this impression from, these guys actually are ex-spies.

Thanks for explaining this, I was struggling to figure out the difference between this and https://www.quantopian.com/ https://www.quantopian.com/ That's actually pretty clever.
