Description of the Invention: [Technical Field] The present invention relates to a password management system, and more particularly to a password management system using a visual password and a method thereof. [Prior Art] With the advent of the multimedia era, for the registration of many life safety management and Internet services, most users use passwords to facilitate memory and easy use, often using the same or similar passwords. Different sets of security devices and network services, this bad habit makes most passwords have a similar form; but to achieve high security of security devices and network services, it is necessary to have different sets of different Passwords and password changes from time to time, this will cause user settings and decryption problems, bad password usage habits are more risk of misappropriation, retrieval, loss or change, security protection loopholes will make users have a big loss. Therefore, it is an important issue for password setting and management. Currently existing password management system (please refer to [1] Wang Xinwei, “Design and Application of High-Efficiency Key Password Management System”, Master Thesis of National Institute of Information Technology and Application, Taichung Institute of Technology, 2008; [2] Xie Wenjun, “ Personal Password Management System, Master's Thesis, Institute of Information Science and Engineering, National Chiao Tung University, 2007; [3] Keep It Secret !

Or the simple module 'can be imageless and stored in the "received to receive the second share map, the user can enter the secret image of the password in the input unit 11, and then according to this: the secret map: - the second sharing image 17 is shared, and the deer-u second sharing image 17 is superimposed on the display image to share the image 16 from the confidential image. If the password is correct, then The first knife image 16 is stored in the storage unit 15, and the image is transmitted to the security. When the protection device 30 is stored, the home access control device can be used as an example, and the user goes home: to the portable device 10', such as a mobile phone, wirelessly connects the device 3G to read the second share stored therein. Having the image 16 :: on the first-divided 13 stored in the storage unit 15 itself, the two are superimposed and the result is displayed on the display device 987 from the user of the display device 13 Once you get it, you can enter it.
