Key-value based data hiding method for NoSQL database

This paper proposes a key-value based data hiding method for NoSQL database. Our proposed method is applied on the database generated by MongoDB (Document-Oriented Database). It only modifies the structure of the key-value attributes for hiding information without affecting the contents stored in the database. On technical aspects, our method allows flexibly to change the sequence of the key-value attributes in order to embed the bit “0” or bit “1” into the rows of tables in the database. After hiding the information into the database of MongoDB, the operations such as select, insert, export, import and so on.
