jHuman is a â€˜human identificationâ€™ plugin. This plugin is seen as a replacement for the standard CAPTCHA that a lot of website owners implement on their sites in order to ensure input comes from a human.
jHuman works by collecting metrics based on how a user interacts with a form. There are a number of identifiable actions that a user will carry out, an example of some of those metrics are:
- Move or use their mouse.
- Enter data into form fields.
- Take time to complete the form.
This collection of information is examined to calculate how likely the end user is to be human.
