System and associated method for ensuring data privacy

A system for processing anonymized data comprising a host computing system including a processor and a memory configured to provide computer program instructions to the processor to execute functions of components:

• a data accessing component for accessing a set of data from a data source including a true element and at least one spurious element, wherein the host computing system cannot differentiate between the elements so as to obfuscate the true element from the host computing system, wherein a true hash value of the true element is provided to a third-party computing system;
• a code accessing component for 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;
• a code executing component for 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 the third-party computing system,
• wherein the 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.

A computer-implemented method for processing anonymized data comprising, carried out at a host computing system and comprising:

• accessing a set of data set of data from multiple data sources each providing a randomized dataset including a true element and at least one spurious element, wherein the host computing system cannot differentiate between the elements so as to obfuscate the true element from the host computing system, wherein a hash value of the true element is provided to a third-party computing system;
• wherein the host computing system includes multiple host nodes each of which has access to all possible permutations of the randomized datasets and includes compressing the permutations across the host nodes, and each host node:
• accesses a code which is executable on the set of data so as to output multiple results for the elements of the set of data;
• processes 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 the third-party computing system,
• wherein the 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.
