# 🦀Image Authentication Scheme Using Blockchain and Merkle Tree🦀
🌟🌟Contributors🌟🌟
🔔 This project needs modification and not production ready.
## Overview
This project implements an image authentication scheme using Merkle tree mechanisms in Rust. The main goal is to achieve image integrity verification by leveraging blockchain technology and the Inter-Planetary File System (IPFS). The proposed method not only verifies the integrity of the image but also restores tampered areas if the image has been altered.
## Features
- **Image Integrity Verification**: Uses Merkle tree mechanisms to verify the integrity of images.
- **Tampered Area Restoration**: Restores the tampered areas of images.
- **Decentralized Storage**: Utilizes IPFS for decentralized storage of images.
- **Blockchain Technology**: Implements blockchain to store the Merkle root for secure verification.
## Files
- `image_into_chunks.rs`: Handles the slicing of images into chunks.
- `image_verification.rs`: Implements the image verification process using the Merkle tree mechanism.
- `image_to_msb.rs`: Converts images to their Most Significant Bits (MSB) for further processing.
- `blockencryption.rs`: Contains functions for encrypting image blocks.
- `blockchain.rs`: Manages blockchain-related operations.
- `merkle_tree.rs`: Implements Merkle tree operations.
- `ipfs_upload.rs`: Manages the upload of image blocks to IPFS.
- `main.rs`: The main entry point of the application.
## Installation
1. **Clone the repository**:
```sh
git clone https://github.com/whoisgautxm/Image-Authentication-Model-in-Rust.git
cd Image-Authentication-Model-in-Rust
```
2. **Install Rust**:
Follow the instructions on [rust-lang.org](https://www.rust-lang.org/) to install Rust.
3. **Build the project**:
```sh
cargo build
```
4. **Run the project**:
```sh
cargo run
```
## Usage
1. **Image Slicing and Encryption**:
- The image is sliced into non-overlapping blocks.
- Each block is encrypted and uploaded to the IPFS system.
2. **Merkle Tree Generation**:
- The unique hash (fingerprint) of each image block is used as a transaction in the blockchain.
- A Merkle tree is generated with these transactions, and the Merkle root is stored in the blockchain.
3. **Image Verification**:
- The Merkle tree for the unverified image is generated.
- This tree is compared with the original image's Merkle tree from the blockchain to verify integrity and identify tampered areas.
## Detailed Workflow
1. **Image Processing**:
- Extract the k Most Significant Bits (MSBs) of each pixel.
- Slice the image into blocks of size N x N pixels.
2. **Encryption and IPFS Upload**:
- Encrypt each block.
- Upload encrypted blocks to IPFS and get their unique hashes.
3. **Blockchain Integration**:
- Use the hashes as transactions to build a Merkle tree.
- Store the Merkle root in the blockchain.
4. **Verification Process**:
- Generate Merkle tree for the received image.
- Retrieve the original Merkle tree from the blockchain.
- Compare both trees to identify tampered blocks.
