Abstract: Systems and methods for ensuring data privacy in a data sharing system are provided. A computer implemented method carried out at a host computing system includes: accessing a set of data from a data source including a true element and at least one spurious element so that the host computing system cannot differentiate between the elements to obfuscate the true element from the host computing system. The method includes: accessing a code which is executable on the set of data so as to output multiple results for the elements of the set of data; processing the set of data, including for each element: executing the code on the element to generate a result; computing a hash value of the element; and outputting the result in association with the hash value to a third-party computing system. A third-party computing system has access to the true hash value of the true element for identification of the result generated by execution of the code on the true element.
