Protection of databases, data transmissions and files without the use of encryption

A method of securing content designated for transmission from a first computing device to a second computing device from unauthorized access, by hiding relationships between units of content, the method comprising:

• obtaining, by the first computing device, a data record designated for transmission to a second computing device, the data record comprising multiple fields;
• obtaining a specific number of additional data records of the same type as the data record designated for transmission, the additional records containing data that is not responsive to a query that returned the record designated for transmission;
• treating the record designated for transmission and the additional records as a data grid comprising multiple records, each record of the data grid comprising multiple fields;
• transforming the data grid into a protected data grid by permuting cells of at least one field of the data grid;
• wherein permuting cells of at least one field of the data grid further comprises applying a permutation algorithm using modular arithmetic to the cells of the at least one field, wherein the permutation reorders the cells of the data grid across multiple records, without altering content of any individual cell;
• transmitting the permuted data grid to the second computing device;
• wherein the at least one permuted field still contains all of the original cells in a permuted order, thereby hiding relationships between the cells of the permuted field and other cells of the data grid;
• and
• wherein the transformed, protected data grid secures sensitive content from unauthorized access by hiding relationships between the sensitive content and other fields of associated data grid records.
