This paper presents the method of steganography that organizes a covert communication channel, by embedding the additional information in the frequency domain. The proposed method of embedding the additional information in the coefficients of the discrete Hartley transforms, due to unavailability of a complex data structures. It has the symmetry of the formulas the direct and the inverse transform that's why it ensures high computational efficiency in the processing of real data type.
