Imagechain-Application of Blockchain Technology for Images

Area of Science:

• Cryptography
• Digital Image Security
• Data Structures

Background:

• Traditional blockchains store data in blocks, separate from linked content.
• Securing digital images often requires complex, multi-file solutions.

Purpose of the Study:

• Introduce Imagechain, a new cryptographic structure for chaining digital images.
• Highlight Imagechain's unique approach of embedding data within image files.
• Demonstrate Imagechain's security, portability, and user-friendliness.

Main Methods:

• Developed a cryptographic structure where digital images are linked via hash links.
• Implemented an embedding process combining image files with data blocks.
• Utilized file hashing to ensure data integrity and prevent tampering.

Main Results:

• Imagechain chains digital images without storing them in separate blocks.
• Each image file contains an embedded data block linking to the previous element.
• The system supports multiple file formats and embedding methods, ensuring portability.
• Hashing the entire file guarantees high security and resistance to forgery.

Conclusions:

• Imagechain offers a secure, portable, and user-friendly method for chaining digital images.
• The embedding process and block structure are key innovations.
• This approach enhances digital image integrity and provides forgery resistance.
