This paper proposes a new numbering method for a fragile watermarking algorithm aimed at improving color medical image watermarking. The proposed method uses Hilbert pattern numbering before watermarking operations such as parity bits check and comparison between average intensities as the authentication data. The authentication data embedded in the same host image are utilized to localize any tamper...
Medical image is seen as one of crucial data that demand for authentication method as it is highly confidential and used in insurance claim, evidence of jurisdiction and personal identification. Nowadays, Hospital Information System (HIS) is used widely at hospitals and clinical departments and it handles thousands of crucial electronic data in medical. We have introduced a fragile watermarking method...
Medical image is seen as one of crucial data that demand for authentication method in order to ensure that data has not been tampered. This paper has conducted a research proposing a recovery feature in an authentication watermark with spiral manner numbering, which shows a good numbering system of embedding. The schema is a fragile, blind watermarking. The operating time taken is short and the result...
