Cookies are text files in data. Txt format) is temporarily stored in your computer by the server so that the server can identify your computer. This paper briefly introduces what cookies are, what functions cookies have, and what problems exist in using cookies in websites.

What are cookies? Simply put, Cookies are text files in data. Txt format) is temporarily stored in your computer by the server so that the server can identify your computer. When you browse the Website, the web server will send a short message to your computer first, and Cookies will help you record all the words or some choices you enter on the website. The next time you visit the same Website, the web server will first check whether there is any Cookie information left by it last time. If there is, it will judge the user according to the content in the cookie and send you the specific webpage content.

What does the biscuit do? Nowadays, many websites in the world are registered with new users. Sometimes they register and when they visit the website again, they will automatically recognize you and say hello to you. Do you feel very kind? Of course, this effect is only superficial. More importantly, websites can use cookies to track and count users' habits of visiting websites, such as when to visit, which pages to visit and the time spent on each page. Using this information, on the one hand, it can provide personalized service for users, on the other hand, it can also be used as a tool to understand all users' behaviors, which has certain reference value for the improvement of website management strategy. For example, if you check the flight schedule on the airline website, the website may have created Cookies containing your travel plans, or it may only record the pages you visited on the website. The next time you visit, the website will adjust the content displayed according to your situation, and put the content you are interested in first. This is an advanced Cookie application. At present, the most widely used Cookies is to record the user's login information, so that you don't need to enter the user name and password for the next visit-of course, this convenience also has the problem of user information leakage, especially when multiple users use a computer.

In addition, some people think that the use of cookies on websites may invade users' privacy, but most users don't know much about it, and this kind of use of users' personal information is mostly used as statistical data, which may not necessarily cause direct losses to users. Therefore, there is no relevant legal constraint on the issue of cookies and user privacy. Many websites still use cookies to track users' behaviors, and some programs require users to open cookies to use them normally. IE browser users can decide whether to allow websites to use cookies to track their information by setting the privacy level in the privacy options, from all restrictions to all restrictions, or restricting some websites. They can also manually set up specific websites to allow or prohibit the use of cookies for editing. The default setting of IE browser is "intermediate"-some websites have restrictions on using cookie. Cookies settings of personal computer (IE browser) can be viewed and modified through the menu "Tools-Internet Options-Privacy".
