Abstract: Browsers are our portal to the web, and if users want a secure, adequate and smart services, websites need to know some information about their browser, operating system and their hardware device. Modern day browsers have evolved a lot; browsers that provide the beauty of the web also provide a dark side, a rich environment of exploitable information that can identify a device. This is called “device fingerprinting,” which is the technique of identifying visitors of a website and verifying if they are who they claim to be. The idea of fingerprinting is to gather some data that helps to recognize the user amongst others. The data collected could be categorized into three main types: Firstly, the device-related data such as graphics card type, and CPU information. Secondly, the information related to the software such as operating system and browser. Thirdly, the user behavioral data such as the mouse speed and keyboard pattern. Websites used to use cookies for identification, however, there is a new and better methodology nowadays. This paper will show what can be used for device fingerprinting as an alternative to cookies. I conclude that there is always a trade-off between privacy and a good service on the internet. Keywords: Fingerprints, browsers, uniqueness, verification, personal data, cookies.
