Systems and methods for manipulation of private information in untrusted environments are disclosed. In one embodiment, in a trusted computing environment comprising at least one computer processor, for a plurality of data records, a method for manipulation of private information in untrusted environments may include: (1) separating each data record into a confidential data attribute and a non-confidential data attribute; (3) calculating an encrypted value for the confidential data attribute using an encryption key; (4) calculating an authentication value for the confidential data attribute using a hash value key; (5) associating the encrypted value and the authentication value in a protected data set; and (6) associating the non-confidential data record with the associated encrypted value and the authentication value; and (7) exporting the protected data set to an untrusted computing environment.
