Abstract
Technologies for privacy-safe security policy evaluation are disclosed herein. An example apparatus includes at least one processor, and memory including instructions that, when executed, cause the at least one processor to curry a security policy function to generate a privacy-safe curried function set, the security policy function to generate a security policy as a function of a plurality of policy parameters, the privacy-safe curried function set including a non-sensitive function that receives a non-sensitive parameter of the plurality of policy parameters as an argument, the privacy-safe curried function set further including a sensitive function that receives a sensitive parameter of the plurality of policy parameters as an argument; access unencrypted parameter data corresponding to the non-sensitive parameter of the plurality of policy parameters; evaluate the non-sensitive function of the privacy-safe curried function set to generate the sensitive function; and provide the sensitive function to a client computing device.
