An efficient steganography method for hiding patient confidential information

Area of Science:

• Medical Imaging
• Information Security
• Data Privacy

Background:

• Cryptography has limitations in protecting sensitive patient data within medical images.
• Steganography offers a complementary approach to enhance security and confidentiality.
• Existing methods may be vulnerable to specific attacks, necessitating advanced solutions.

Purpose of the Study:

• To propose a novel steganography algorithm for secure embedding of patient confidential information in medical images.
• To enhance the confidentiality and integrity of patient data during exchange or storage.
• To address the limitations of traditional cryptographic methods in medical image security.

Main Methods:

• Utilizes Pixel Value Differencing (PVD) to identify image contrast regions for embedding.
• Employs a Hamming code to embed 3 secret message bits into 4 bits of the cover image.
• Applies embedding exclusively to the Region of Non-Interest (RONI) to preserve the Region of Interest (ROI).

Main Results:

• Successfully demonstrates a new steganography algorithm for medical image data security.
• Achieves secure embedding of confidential patient information.
• Preserves the integrity of the Region of Interest (ROI) during the steganographic process.

Conclusions:

• The proposed steganography algorithm provides an effective method for securing patient information in medical images.
• This approach enhances data confidentiality, complementing existing security measures.
• The technique offers a robust solution for protecting sensitive medical data.
