碩士 === 國立高雄應用科技大學 === 電子工程系 === 97 === The immediacy and convenience of the network ATM has recently become both reliable and vital tool for modern people. We can implement either the business trades in electronic commerce or the financial transaction among banks just through the each individual network ATM of all the banks. However, it is only to be expected to risk taking a chance for us to use the network ATM on the Internet, especially under such an informative and technical environment. The purpose of this essay, is to compare the network ATM safe protection which combines rather effective watermark technology under bidden figure distinguish system. With dynamic keyboard input password system wildly used by china trust Commercial Band and Bank of Taiwan that is for getting on the network ATM. Moreover, they add dynamic figure distinguish system which is frequently applied to websites recently to prevent from cracking passwords by continually making an attempt and provides several stages of protection against the invasion of hackers and virus programs. After making a comparison between the entrance of the network ATM safe protection among banks, we can find there are merely one or two steps of the safe protection system presently as well as prompt warning messages while incorrect passwords being input by users. These tactics are not enough for the safe protection system. My essay focuses not only on this but also tacks on one more identifying procedure. Furthermore, I have changed the sequence. The message of incorrect passwords doesn’t appear until the end of all procedures. Therefore, it is definitely effective for the suggestion of my essay to perfect the network ATM safe protection system.
