This can help prevent unauthorized access, even if the user's credentials have been compromised.

F: Strategy 5: Advanced Captcha

What is Advanced Captcha

Advanced Captcha is an evolved version of the traditional Completely Automated Public Turing Test to Tell Computers and Humans Apart (CAPTCHA) system designed to differentiate between legitimate human users and automated bots. This security measure is often employed as a deterrent to fraudulent and malicious activities, such as account takeovers, unauthorized transactions, and spamming, which are potential contributors to chargebacks.

How does it work

Advanced Captcha works by presenting users with complex puzzles, challenges, or tasks that must be solved to confirm their authenticity. While basic CAPTCHA tests may involve simple pattern recognitions, such as distorted text or basic arithmetic problems, advanced Captcha systems may employ more sophisticated techniques, like image recognition, interactive tests, or even game-like tasks. The underlying premise is that these challenges are easier for humans to solve than they are for bots, thus allowing secure authentication and access control.

Pros & Cons

• Pros: One significant advantage of implementing advanced Captcha is its effectiveness in mitigating bot-driven account takeovers and unauthorized transactions, as bots typically struggle to solve these types of challenges. This added layer of protection is beneficial for Fiserv professionals, payment processors, and online merchants in managing the risk of chargeback disputes resulting from fraudulent activities.

  
  

• Cons: On the downside, advanced Captcha tests can create user friction by making navigation and transaction processing more cumbersome.
