Frequently Asked Questions

General

What is GPTBUSTER and how does it work?

gptBuster is an open-source protocol and JavaScript widget designed to combat spam and abuse on websites and web applications. It utilizes a Proof of Work (PoW) mechanism instead of user testing or puzzles.

gptBuster is and addition commercial product that adds and extra layer of security.

How does the Proof of Work (PoW) mechanism in GPTBUSTER work?

PoW requires users to complete a computational task to validate their interactions. This task is resource-intensive, making it difficult for unsophisticated bots to bypass.

What role does the Sentinel play in GPTBUSTER?

The Sentinel enhances gptBuster's effectiveness by incorporating IP verification, blacklist checking, and advanced content analysis to detect and block spam and malicious actors.

How does GPTBUSTER handle IP verification and blacklist checking?

gptBuster analyzes IP addresses to identify those from data centers or TOR proxies and checks these IPs against known blacklists to prevent spam from known malicious sources.

Is GPTBUSTER compliant with privacy regulations?

Yes, gptBuster is fully compliant with data protection laws worldwide. It operates as a cookie-less solution and respects user privacy without relying on intrusive tracking mechanisms.

Is GPTBUSTER compliant with accessibility regulations?

Yes, gptBuster is WCAG AA+ compliant.

How does GPTBUSTER improve user experience compared to traditional CAPTCHAs?

GPTBUSTER enhances user experience by minimizing friction and accommodating automation. Unlike traditional CAPTCHAs, which can be tedious and disruptive, gptBuster provides a smoother interaction.

Can GPTBUSTER be customized for different security needs?

Yes, gptBuster is highly flexible and can be tailored to various scenarios. It allows for server-side enhancements and integration with additional mechanisms such as email or phone verification.

How does GPTBUSTER compare to reCAPTCHA and other solutions?

GPTBUSTER excels in privacy compliance, user experience, and adaptability compared to reCAPTCHA and other solutions. It offers stronger privacy protections, better support for automation, and effective spam reduction.

Technical

How do I integrate GPTBUSTER with my server?

GPTBUSTER can be integrated with your server using official libraries for various programming languages or through the official API. For detailed integration instructions, refer to the official libraries.

What are the key steps in the PoW verification process for GPTBUSTER?

The PoW verification process involves:

  1. User initiates verification.
  2. Widget requests challenge data from challengeurl.
  3. Widget solves the challenge.
  4. User submits the form with the solved challenge.
  5. Server validates the submitted payload against the expected solution.

How does GPTBUSTER handle challenge complexity and verification?

GPTBUSTER uses SHA-hashing to manage challenge complexity, requiring three passes of SHA computation for both challenge generation and verification. The difficulty of the computational task can be adjusted using the maxnumber parameter.

The validation process includes:

  1. Decoding and parsing the Base64-JSON-encoded payload.
  2. Verifying the algorithm, challenge, and signature.
  3. Ensuring all checks pass to confirm the request as valid.

See Server Integration.

How can I prevent replay attacks with GPTBUSTER?

To prevent replay attacks, implement measures to invalidate previously solved challenges. Maintain a registry of solved challenges and reject any submissions that attempt to reuse a challenge that has already been solved.

See Security Recommendations.
