CAPTCHA is an essential tool in preventing automated bots from accessing websites and apps, but it can also be frustrating for users. Over recent years, there has been an explosion in the number of CAPTCHA types available, each with its own unique UI to cater for the changing market demand. Some of the newer types of CAPTCHAs include a dynamic image that contains various elements and requires users to arrange them in a specific way, while others ask users to identify specific objects within an array of images or listen to an audio clip and transcribe what they hear.
Despite the growing variety of CAPTCHAs, it is their security that is constantly being tested and challenged by increasingly sophisticated bots. Therefore, it raises concern for websites, apps and individual users that the increasing CAPTCHA types are for the sake of security or just marketing hype.
When user clicks on the CAPTCHA button, they are presented with a challenge that is for websites and apps to distinguish their human-like abilities. The methods vary among CAPTCHA vendors. Generally speaking, there are 3 common methods:
In addition to these common methods, some bot mitigation vendors employ more advanced techniques to detect bots. For example, some challenges may involve biometric features to verify the user's identity through unique physical characteristics, such as fingerprints or facial recognition. But this is still a relatively new technology and not all devices support this authentication. Additionally, biometric authentication may raise privacy concerns for some users.
To put it briefly, CAPTCHA security strategies are triggered the moment a user arrives on a website (only if it is deployed CAPTCHA), and the interaction between the user and CAPTCHA challenges is part of the strategies. Different CAPTCHA challenges and looks serve a specific need which can be a crucial step among security rules or an essential part of a website’s custom design.
Ultimately, both CAPTCHA looks and security rules are important for the effectiveness of the CAPTCHA system. CAPTCHA looks to determine the user experience of website visitors which is tied directly to a website or app's success — revenue, while CAPTCHA security strategies are equally important as they ensure that the CAPTCHA system is able to detect and block bot activity effectively.
