| 内容記述 | This paper proposes a new type text-based CAPTCHA using both Jawi script and Latin script which are used to describe Maley language. Many web sites come to provide CAPTCHA to prevent bots and other automated programs from signing up for email, spamming comments, violating privacy, and preventing brute force login attacks on user accounts. Text-Based CAPTCHAs are the most common and earliest CAPTCHA. But as optical character recognition (OCR) technology has improved, the intensity of distortions that must be applied to CAPTCHA for them to remain unrecognizable by OCR has increased. This has reached a point where humans are having difficulty in solving the CAPTCHA. The idea of the proposed CAPTCHA is to generate one same string written in Latin scripts and Jawi scripts. Since some of the string’s characters are hidden by the interference, users need to combine both strings to solve this CAPTCHA. This idea is uses that the fact that almost Jawi characters are one-to-one correspondence with Latin characters, A series of experiments was carried out to evaluated the performance of the proposed CAPTCHA. First, some OCR softweres were prepared and it was clarified that they could not read the partially hidden Latin and Jawi strings. Next, A computer program was developed using computational technique such as PHP, JavaScript, and so on for the usability evaluation. 13 experimental subjects participated the experimetns. The results of the experiments showed that the averate time to solve the CAPTCHA and the accuracy rates were acceptable compared with the indices shown in the existing research. | |||||
