| 内容記述 | We developed the watermark method to identify the patient-ID and institution-ID. The image process-ing modified the watermark information and we recovered the watermark by the error correction meth-ods. We used the BIT-swapping method for embedding watermark. After image processing, the detec-tion ratio of the watermark was decreased. To correct the patient-ID and institution-ID, we used three type of methods, (1)Bose-Chandhuri-Hocquenghem code, (2)Majority correction method and (3)scramble location method. Once the detection ratio of watermark was decreased to 60%, we could recovery the watermark information. The peak signal to noise ratio was 39 dB at LSB-swapping. We think that these watermarking methods are suitable to the medical images. | |||||
