| Outline of Final Research Achievements |
"Digital watermarking technology" is a technology that can conceal the names of image generating facilities and diagnostic findings in medical images. On the other hand, "Steganography technology" is a technology to conceal medical images from general images when transmitting medical images. These "secret technologies" are understood as encryption technology, but since "confidential technology" is not clearly confidential of information, motivation for illegal decryption does not occur.
In our method there was no capacity change of the image whose information was kept secret. In addition, the image quality evaluation index PSNR (Peak Signal to Noise Ratio) ≦ 40 dB, the structural similarity (Structural Similarity) ≧ 0.995 can be secured, and the hash value has not changed at all even before and after information transmission.
