11. Summary of the new findings of the thesis:  

- Suggested use of Hamming code in hiding process to avoid receiving wrong information; suggested select data samples, bit on each sample, bit adjustment on each sample to improve the confidentiality of the hidden technique and reduce the difference between the host file and stego-file.

- Apply two methods of hiding information in the media to audio file, by adjusting 2 bits in 25 samples to hide 4 bits and adjusting one bit in 256 samples to hide 8 bits.

- Improved hiding techniques using echo modulation and proposed two techniques for hiding information on the frequency domain, using Fourier transform and wavelet transform.

12. Practical applicability, if any: The proposed techniques can be used to develop information security applications.      

13. Further research directions, if any: Combine the proposed techniques with hardware devices to build real-time security applications.
