Privasea Enhances TON Network with FHE Services for Security and Compliance

“Secure LivenessCheck Bot” - Revolutionizing Authentication on Telegram with FHEML by Deploying Privasea AI Network on TON Network.


In an era where digital security is more critical than ever, Privasea is proud to introduce a groundbreaking solution for Telegram users based on the TON network. TON network is a decentralized and open internet, created by the community using a technology designed by Telegram.

This innovative solution called “Secure LivenessCheck Bot” is designed to redefine user authentication by harnessing the power of advanced face recognition technology coupled with Fully Homomorphic Encryption [FHE]. As cyber threats become more and more sophisticated, “Secure LivenessCheck Bot” stands as a bastion of security, offering unparalleled protection for users' digital identities.

What is a “Secure LivenessCheck Bot”?

“Secure LivenessCheck Bot” is a Telegram bot that provides a secure and convenient method of authentication. It uses a state-of-the-art face recognition system to confirm user identity and employs FHE to maintain privacy and security. By ensuring that all facial data is encrypted before it leaves the user's device, “Secure LivenessCheck Bot” guarantees that this sensitive information remains confidential and impervious to cyber threats.

How “Secure LivenessCheck Bot” Works

The magic of “Secure LivenessCheck Bot” lies in its simplicity and robust security measures. When a user registers with the bot, they submit a photo ID. The bot then extracts a face embedding vector—a unique digital signature of the user's facial features. This vector is encrypted using FHE, a cryptographic algorithm that allows computations to be performed on encrypted data, and securely stored in the database.

For authentication, the user takes a selfie with their smartphone camera. The bot processes this photo to extract the face embedding vector, encrypts it, and sends it to the server. Here's where FHE shines: the comparison between the stored vector and the new one occurs in an encrypted domain without decrypting, ensuring the actual facial data is never exposed to a third party. Once authenticated, the user receives an encrypted confirmation, maintaining security throughout the entire process.

Benefits of “Secure LivenessCheck Bot”

The benefits of “Secure LivenessCheck Bot” are threefold:

  • Security: By employing FHE, “Secure LivenessCheck Bot” ensures that raw facial data is never exposed during transmission or authentication, significantly reducing the risk of data breaches.
  • Privacy: Users' biometric data is their own. This bot’'s encryption methods ensure that this data cannot be accessed by unauthorized parties, including server administrators/owners.
  • Convenience: Authentication happens seamlessly within the Telegram app. Users don't need to remember passwords or use additional hardware tokens.

Use Cases for “Secure LivenessCheck Bot”

“Secure LivenessCheck Bot” has a wide range of potential applications, from securing Telegram group chats with sensitive content to providing secure access to private channels. It can also be integrated with other systems to serve as a secure login mechanism for various online services, making it a versatile tool for both personal and business use. Examples include its use for anti-Sybil authentication during airdrops or as a liveness check for DApps.

Looking to the Future

The team at Privasea is committed to continual improvement. Future developments for “Secure LivenessCheck Bot” may include even more robust encryption algorithms, additional layers of security, and expanded use cases. As digital security evolves, “Secure LivenessCheck Bot” will evolve with it, always prioritizing user privacy and convenience.

We will provide ecosystem support and future integration for KYC (Know Your Customer) and liveness checks for DeFi platforms and Real World Assets (RWA) within the TON ecosystem.
