Abstract:

This PhD thesis explores the development of effective techniques for recovering secret images in Visual Cryptography (VC). VC is a cryptographic technique that encodes a secret image into multiple shares, allowing the original image to be reconstructed only when a certain number of shares are combined. The thesis focuses on improving the quality of the recovered image and reducing errors introduced during the sharing and reconstruction processes.

Key areas of investigation:

• Communication network: Explores how different communication channels and noise levels impact image recovery.

• Image recovery: Investigates novel algorithms and techniques for improving the fidelity of the recovered image.

• Error reduction: Analyzes methods for minimizing errors caused by factors like compression and transmission noise.

• Technological advancements: Discusses the potential of emerging technologies like machine learning to enhance VC security and image recovery.

Overall contribution:

This thesis contributes to the field of VC by proposing innovative techniques and analyzing the impact of various factors on image recovery. The findings advance the understanding of VC capabilities and offer valuable insights for developing robust and reliable image security solutions.

Keywords: Visual cryptography, image recovery, error reduction, communication network, technological advancements
