Captcha CK is a handy and effective extension for Joomla, designed to protect forms from spam and automated bots. It is a great alternative to Google reCAPTCHA and other similar solutions, offering a quick and easy way to strengthen the security of your site.
Captcha CK's main features
Form submission verification
Captcha CK analyzes the form submission process and determines if the form was submitted through a normal browser. This helps to weed out automated submission attempts by bots.
Hidden Bait Field
A hidden checkbox is added to the form code that is inaccessible to users but can be seen by bots. If the bot tries to check it, the system automatically blocks the form submission.
Protection with time trap
You can set a minimum time required to submit a form. If the form is submitted too quickly, this indicates bot activity and the system prevents submission.
Math Check
The user is asked to solve a simple arithmetic equation (such as adding or subtracting numbers) before submitting the form. This element is displayed as an image using JavaScript and is only visible in the browser, making it unsuitable for automatic recognition by bots.
