6. CONCLUSIONS
This supply chain application supplier ranking and quota as its approach in the selection of suppliers who will supply the
products ordered by consumers. When consumers order one type of product, then the application will sort the supplier
based on ranking and quota checking capabilities in a single supplier. Ranking of suppliers are entered manually by the
application to be expected that the future of these applications can be combined with calculations made by the intelligent
systems in terms of setting ranking. Supplier selection can automatically make the process of booking transactions from
the consumer to the supplier more quickly done. The process is done to check whether the record table does not supply
more quantity of quota owned suppliers. The system will automatically send a request to the supplier on the number of
orders that have previously been treated by quotas and rank. And provide feedback if the supplier does not receive the
order.

ABSTRACT
CAPTCHA is a technology which has its base in a test called the Turing Test. Alan Turing, proposed this test as a way to
examine whether or not machines can think or appear to think like humans. The main purpose of a CAPTCHA is to block
form submissions from spam bots- that is automated scripts. Various types of CAPTCHAs are used, which mostly requires
users to enter the strings of characters that appear in distorted form on the screen. These types of distorted stings are unable
to understand by bots but human can. The CAPTCHA types are either text based or image based. In this paper, a new color
based CAPTCHA is described, which provides color based images to human and human will answer to interrogator with
color name or so on the question asked during turing test. These colored images can have single color image, more than
one color image or it can have images with objects like monitor, car, flower etc. For these types of questions, the
computer machine will be unable to answer and it means unable to break CAPTCHA. This paper describes in detail the
proposed CAPTCHA technology principle, method of implementation, variations and comparison of the accuracy
rates. We conducted various experiments to measure the viability and usability of this CAPTCHA approach. An
accuracy of 100, 95 and 90 is observed with single color, multi color and color image based CAPTCHAs
respectively.
