This would require some knowledge of the related layers involved.

You would then craft a payload, which would compute/calculate the "client signature" out-of-band, not within the browsers standard request cycles and compute a signed, self validating hash, stored as a cookie. You may even be able to use a browser API, depending on the target browser. One method I can think of, is through a custom browser extension/plugin. And even if client can manipulate this too is there still a way that we can atleast make it difficult for a client to fake about browser and os ? I am still trying to figure out how they exactly work for getting the os and browser name. So on learning about Device fingerprint i got to know about a javascript library called FingerprintJs and it seems that they don't rely on userAgent for finding out the clients os name as i tried using it and turns out that on manipulating userAgent i got the original result. And it turns out that even mnc's like amazon and facebook rely on userAgent. So according to these we can only do it with the help of userAgent And it is not a difficult thing for a client to change it and also there is no way that we can detect that if a client has modified it.

LILYPOND FORMAT HOW TO
How to prevent user-agent to be changed by user.Retrieving Browser, OS and Device Type By Parsing User Agent.But some websites show that there is only one way to do it that is by using request header userAgent. But the thing is that we don't want the user to be able to manipulate information about os or browser. So i have to get a client's browser and os name.
