Everybody that uses an E-commerce store should always be concerned about website security according to Aladwani and Palvian (468). E-commerce mainly involves the processing of credit cards and sensitive user information and therefore the security of the website should be treated with great care during its overall design. Over the years there has been an increase in cases over stolen credit numbers and synthetic identity theft more so among people whose personal information is stored digitally and those who engage in e-commerce. Meliá n-Alzola and Padró n-Robaina (327) advocate for a document centred approach to computer interfaces that cover several radical changes to the current situation of operating systems.
Every software package should be designed as a set of tools accessible to users on any document web pages. For example, in the middle of surfing the web, a user should be able to perform other duties such as computation by writing on a document. The authors also suggest that an interface should be zoomed in what he calls a Zoom world where the user navigates around a two-dimensional plane having a geographical representation of every document on the computer.
Zooming enables users of the interface to see all the documents in order to read or edit the document. They further propose that the interface design should be subjected to regulation in various ways. This can be done by establishing legal safeguards to protect users from harm and coming up with professional guidelines and standards to evaluate interface security. Meliá n-Alzola and Padró n-Robaina (325) also state that there are two laws of interface design, based on fictional laws of robotics created by Isaac Asimov. The first law states that a computer shall not destroy the user’ s work, or allow the user’ s work to come to harm while the second law states that a computer shall not waste the users’ time or require the user to do more tasks than that that is required.
Pratt, Mills and Kim (75) propose the following principles: First, the design should structure the user interface purposefully and useful ways based on clear and consistent models that are recognisable to users, combining related things together and separating unrelated things, outlining dissimilar thing and making two things resemble one another.
Secondly, the design should prepare all needed options and requirements for a given task visible and not distracting the user with redundant information the best designs should not overwhelm the users with several alternatives or confuse the user with irrelevant information.
