Abstract
Systems and methods of the present invention provide for one or more server computers communicatively coupled to a network and configured to: receive a request to execute a computational task, including a transformed input used to execute a computational task. A client computer transforms the original input into the transformed input, using an affine mapping where the transformed input is a one-to-one equivalent to the original input (but which can't be inferred by the server computer), and according to a user selection limiting the computational complexity of the mapping according to resource constraints on the client. The server may then execute the computational task and transmit a result to the client to apply an inverse affine mapping, and receive a response which verifies that the computational task result is complete and valid.
