Mathematical Captcha, the most simple and effective method

By applying 3 security systems on your forms, you protect yourself from all known attacks to date and certainly from new ones that may appear.

The captcha of this module is a simple mathematical calculation to solve for a human being, but more complex for a robot.

The main advantage of this system is that it is not dependent on any external actor and you keep all your data and those of your customers in your shop, guaranteeing them a total security and legal autonomy.

You will notice that on the registration form, no captcha appears, it seems obvious to me that this form should not contain any constraining or disruptive element that could prevent the registration of your customers. I have therefore implemented 2 additional securities on this form to allow only humans to validate their registration on your shop.

The implementation of the security of the registration form was essential following the massive attack of PrestaShop version 1.7 at the beginning of June 2020. Of course, the security proposed on version 1.7 of PrestaShop is also proposed for all the versions of PrestaShop compatible with my module in order to protect the sites from any new attack.
