• Information Security
• Digital Image Processing

Background:

• Emerging internet applications necessitate robust solutions for confidential data handling.
• Existing data hiding techniques face challenges in capacity, imperceptibility, and security.
• Ensuring data privacy and security in digital communications is paramount.

Purpose of the Study:

• To propose a new blind data hiding scheme for secure information embedding.
• To enhance data hiding efficiency using the Fresnelet transform combined with wavelet transforms.
• To address privacy and security concerns in internet applications handling confidential data.

Main Methods:

• Data decomposition using the Fresnelet transform.
• Inverse Fresnelet transform on subbands to obtain a coded information pattern.
• Embedding the coded pattern into cover image subbands using wavelet transforms.
• Utilizing different key parameters for the inverse Fresnelet transform.

Main Results:
