Captcha Technology Using a Puzzle    

Puzzle Captcha is more secure, easier and faster to complete than commonly used text based captcha methods.


Captcha is a way of telling humans and computers apart automatically.

A captcha is a program that protects websites against bots (robots) by generating a test that humans can pass but current computer programs cannot.

Puzzle Captcha is more secure, easier and faster to complete than commonly used text based captcha methods. It can protect websites and online applications against automated systems by providing a small task that humans can pass but current computer programs cannot.

People hate cpatchas. Captchas are often difficult to complete correctly. Multiple tests with wrong answers are very frustrating. On a mobile screen the small distorted letters with their confusing backgrounds are very difficult to read. In sunlight the problem is worse.

Captcha was created to tell machines from humans. It is a cruel joke that machines (computers) are able to correctly interpret the tests that are designed to defeat them and humans are finding the tests impossible or problematic. Multiple fail attempts with a captcha result in some users turning away. This is a terrible outcome for a retailer who wants customers to visit, find a product and purchase. A retailer may use captcha to prevent a bot from scraping pricing information from their online shop and using that data in another site for price comparison and to drive sales to a competing retailer.

Puzzle captcha provides a user with a set amount of time to choose the correct puzzle piece. The pieces are at angles and slightly overlapping to confuse automated scanners. The puzzles and the piece removed are randomly chosen. The image is selected from an image folder and automatically converted to a jigsaw puzzle.

The puzzle captcha is designed to be:

1. Operated by a single finger or cursor movement
2. Fun
3. Attractive
4. Secure

Solving a puzzle catcha problem relies on problem solving. The problem can be very simple and preserve security. Puzzle captcha also turns a test of humanness into a game.

Primary Application of the Technology

Prevent Comment Spam in Blogs
Ensure only humans can enter comments on a blog.

Protect Website Registration
Prevent automated scripts from obtaining humans accounts.

Protect Email Addresses From Scrapers
Spammers crawl the Web in search of email addresses posted in clear text. It is possible to use of a puzzle captcha to hide your email address from Web scrapers.

Protect Online Polls
A puzzle captcha ensures that only humans can vote.

Prevent Dictionary Attacks
Prevent dictionary attacks in password systems.

Control Search Engine Bots
Use a puzzle captcha to control the loading of a webpage. It is sometimes desirable to keep web pages unindexed to prevent others from finding them easily.

Prevent scrapers from harvesting information from your website of e.g. an online store and using this information in ways that damages your reputation or commercial opportunity.

The Problem Solved by the Technology

Captchas were designed by their Carnegie Mellon University inventors to thwart bots (automated hacker programs) that might bring online services to their knees. For example, some bots sign up for Hotmail or Yahoo e-mail accounts by the thousands for the purpose of spewing spam. Some post bogus comments in hopes of raising a site’s search-results ranking.

In theory, only an actual human being can figure out what word is in the captcha graphic. The letters are just twisted enough and the background is just cluttered enough that a person can read them, but not a computer. Good guys in, bad guys out—the perfect barrier.

In practice, captchas have just replaced one public nuisance with another. First of all, the images are often so distorted that even a human can’t read them. That’s a particular problem in nonsense words like “rl10Ozirl.” Are those lowercase Ls or number ones? Zero or letter O?

Overall, the Carnegie Mellon team estimates that we spend a cumulative 150,000 hours at the gates of these irritating obstructions every single day. In a newer variant, called reCaptcha, at least that time is put to public use. You see a muddied-looking word that comes from a wonky scanned Google book; when you type what it really says, you’re actually helping out with the process of cleaning up and recognizing an actual text.

The world's largest online ticket retailer is to stop requiring users to enter hard-to-read words in order to prove they are human.

Captcha - which asks users to type in words to prove they are not robots trying to cheat the system - is used on many sites.

But Ticketmaster has moved to ditch it in favor of a simpler system.

It means users will write phrases, such as "freezing temperatures", rather than, for example, "tormentis harlory".

How the Technology Solves the Problem

The user is asked to choose a puzzle solution to pass the human test.
This may be jigsaw piece.

Competitive Advantage

1. Easier to complete than text based captcha
2. Fun to do
3. Looks attractive on a tablet or phone screen
4. Faster
5. One click or a tap with a finger and you are done
6. Can be read more easily
7. Involves problem solving not just copying
