Abstract: A password is said to be secure, if it is resistant to various forms of attack. The oldest authentication approach used in computer systems is the text-based approach, which requires that the user supplies textual password in order to gain access to the system. Overtime, this approach has been shown to have a significant drawback and several vulnerabilities, one of which is the difficulty involved in remembering textual passwords. Textual passwords are vulnerable to several attacks like brute force attacks, shoulder spying, dictionary attacks etc. Graphical Password was introduced which involves the use of images for user authentication. In this research work, we developed a position-based multi-layer graphical user authentication system, in order to solve shoulder surfing attacks that most graphical password authentication schemes are faced with. The system authenticates users in three different phases so as to ensure maximum system security. The exact position of the images that the user selects during the registration phase will make up the user’s password. However, the images will be randomized during the login phase in order to confuse attackers. The newly develop system was evaluated using three performance metrics: (1) Security, (2) Usability, (3) Reliability, and the result showed that the newly developed methodology is suitable for use, very reliable and provides maximum system security.

Abstract: To solve the conflict between the low production efficiency of shoe patternmaking in the footwear industry and the increasing requirement for customization of shoe goods, this paper aims to explore a parametric patternmaking technology to promote the efficiency of patternmaking for customization of female leather shoe last. Through an experimental study, a parametric patternmaking model of the shoe last bottom has been established based on the parametric drawing function in AutoCAD. In this patternmaking model, the flat geometric shape of the shoe last bottom has been modelled through the tool of graphic constraint in AutoCAD, while the essential measures and their proportions have been parameterized by the tool of dimensional constraint. A series of tests to this parametric patternmaking model demonstrated that the original model can be modified in shape and dimensions automatically and quickly according to changes in parameters’ values controlled by foot sizes. Depending on the results of this study it can be concluded that parametric drawing technology can be employed to create various patterns of the shoe last bottom for customization of shoes’ patternmaking to meet various individual requirements with relatively high efficiency. The achievement of this study can also be employed in the patternmaking of the shoe upper and even other kinds of products for customization.
