27 Building User Authentication and Personalization IN THIS PROJECT,YOU GET USERS TO REGISTER at your website. After they’ve done that, you can track what they’re interested in and show them appropriate content.This behavior is called user personalization. This particular project enables users to build a set of bookmarks on the Web and suggests other links they might find interesting based on their past behavior. More generally, user personalization can be used in almost any web-based application to show users the content they want in the format in which they want it. In this project and the others to follow, you start by looking at a set of requirements similar to those you might get from a client.You develop those requirements into a set of solution components, build a design to connect those components together, and then implement each of the components. In this project, you implement the following functionality: n Logging in and authenticating users n Managing passwords n Recording user preferences n Personalizing content n Recommending content based on existing knowledge about a user Solution Components For this project, your job is to build a prototype for an online bookmarking system, to be called PHPbookmark, similar (but more limited in functionality) to that available at Backflip at http://www.backflip.com.
570 Chapter 27 Building User Authentication and Personalization This system should enable users to log in and store their personal bookmarks and to get recommendations for other sites that they might like to visit based on their personal preferences. These solution components fall into three main categories: n You need to be able to identify individual users.You should also have some way of authenticating them. n You need to be able to store bookmarks for an individual user. Users should be able to add and delete bookmarks. n You need to be able to recommend to users sites that might appeal to them, based on what you know about them already. Now that you know the idea behind the project, you can begin designing the solution and its components. Let’s look at possible solutions to each of the three main requirements listed. User Identification and Personalization Several alternatives can be used for user authentication, as you have seen elsewhere in this book. Because you want to tie users to some personalization information, you can store the users’ logins and passwords in a MySQL database and authenticate against it. If you are going to let users log in with usernames and passwords, you will need the following components: n Users should be able to register their usernames and passwords.You need some restrictions on the length and format of each username and password.You should store passwords in an encrypted format for security reasons. n Users should be able to log in with the details they supplied in the registration process. n Users should be able to log out after they have finished using a site.This capability is not particularly important if people use the site from their home PC but is very important for security if they use the site from a shared PC. n The site needs to be able to check whether a particular user is logged in and access data for a logged-in user. n Users should be able to change their passwords as an aid to security. n Users should be able to reset their passwords without needing personal assistance from you.A common way of doing this is to send a user’s password to him in an email address he has nominated at registration.This means you need to store his email address at registration. Because you store the passwords in an encrypted form and cannot decrypt the user’s original password, you actually need to generate a new password, set it, and mail it to the user.
