Visual Captcha WS

This component is based on Visual Captcha(http://visualcaptcha.net/) and aims to isolate backend and frontend behaviors using JQuery and HTML5 resources to client side and JAX-RS to server side.

Some changes must be done, like:

1. Convert project to a Maven project
2. Give a better treatment to client routes
3. Add visual feedback to valid/invalid choices

It was developed using Java version 7 and JQuery 2.2.4.

Above are Java libraries necessary to use this component. (all of then are at WEB-INF/libs folder)

• asm-3.1.jar
• gson-2.1-javadoc.jar
• gson-2.1-sources.jar
• gson-2.1.jar
• jersey-core-1.11.jar
• jersey-json-1.11.jar
• jersey-server-1.11.jar
• jersey-servlet-1.11.jar
• jsr311-api-1.1.1.jar

#Workflow

• Client requests a new captcha
• Server creates a list containing five image options and one audio option.
• One of them is marked as the corret option.
• The response is sent back as JSON.
• JQuery component invokes Visual Captcha client and storage data into a temporary localStorage.
• User selects an option.
• JQuery component validates it.
