At vChars, we ensure the integrity, authenticity, and quality of your data using advanced verification mechanisms, all while keeping your privacy intact. Below, we outline the secure and transparent process behind data verification.

​

🔒 Your Data, Your Privacy

• Encrypted Data Only: Your data never leaves your device unencrypted. All processing and validation occur in a secure environment, ensuring that only you have the right to disclose your information.

• Trusted Execution Environment (TEE): Data validation is performed inside a secure enclave, protecting it from unauthorized access or tampering.

​

✅ The Verification Process

vChars AI employs a Proof of Contribution mechanism to evaluate and verify your data. Each dataset is validated across four key traits:

​

1. Uniqueness

We ensure your data is original by generating a cryptographic hash of the dataset and comparing it against existing hashes stored securely on Filebase.

• If the hash is unique, your contribution is accepted.

• Otherwise, the data is flagged as a duplicate.

​

2. Ownership

Ownership is verified through cryptographic checks using your Telegram WebApp data:

• A secure hash is generated from your Telegram metadata and compared to your submission.

• The process ensures the Telegram ID in the data matches your identity, confirming you own the data.

​

3. Authenticity

Authenticity checks verify the type of conversation data provided:

• Only valid data types, such as personal_chat or ai_chat, are accepted.

• This ensures that the data matches the expected format and use case.

​

4. Quality

We analyze the quality of your dataset based on the following factors:

• Content Quality: Measures the ratio of meaningful messages versus empty or incomplete ones.

• Time Quality: Penalizes large gaps in message timestamps or invalid date formats.

• Interaction Quality: Evaluates engagement levels, such as replies and interactive content.

Each component is scored individually, and an overall quality score is calculated using weighted averages.

​

📊 How Data is Scored

The final score is determined as follows:

• Quality Score: 60% weight

• Ownership Verification: 40% weight

• Validity: Data is considered valid only if the uniqueness score is 100%.

Detailed stats and quality metrics are provided to you upon verification.
