| Slogan: "Helping Your Furry Friends Find Their Way Home"

Imagine a world where losing your beloved dog doesn't mean losing hope. Our innovative project leverages the principles of Apple’s AirTag technology combined with the security of blockchain to create a community-driven network for locating lost pets.

Problem Statement:

• High Incidence of Lost Pets: Losing a pet is a common and distressing experience for many pet owners. The current methods for finding lost pets, such as posting flyers or relying on social media, are often inefficient and ineffective.

• Lack of Real-Time Tracking: Traditional methods lack real-time tracking capabilities, making it difficult to pinpoint the exact location of a lost pet. This delay can significantly reduce the chances of finding the pet quickly and safely.

• Limited Community Involvement: Without a structured system to incentivize community involvement, there is often a lack of motivation for people to actively participate in searching for lost pets. This limits the potential for a coordinated and effective search effort.

Solution:

• Blockchain-Enabled Tracking Network: Our solution utilizes a blockchain-based network to securely and accurately track lost pets. By leveraging Apple’s AirTag technology and combining it with blockchain, we provide a robust and tamper-proof system for real-time location tracking.

• Real-Time Updates and Encryption: The system uses homomorphic encryption to ensure that location data is securely transmitted and stored on the Inco blockchain. Users can report sightings and update the pet's location in real-time, significantly improving the chances of a swift reunion.

• Incentivized Community Participation: To foster active community involvement, we implement a rewards system within the app. Users earn rewards for contributing to the search efforts, creating a motivated and engaged network of pet lovers dedicated to bringing lost pets home.

How It Works:

• Public Key Generation and Data Storage:

Utilizing private keys stored in iCloud Keychain, the system generates public keys for the next 48 hours. Apple use P224 and counter to generate a public and lookup key. These public keys are securely stored in the Data Available Layer (DA), ensuring they are unique and leak-proof.

• Homomorphic Encryption and Location Updates:

Final location data is encrypted using homomorphic encryption and uploaded to the INCO blockchain. If a match is found in the DA, the latest location can also be updated and uploaded by other users.
