Get information from the customer

Question

This may sound like a silly question, but I’m kind of in trouble here.

I need to collect through the browser some information that helps me identify the client that is browsing. I already know the MAC address I won’t be able to get. But would it be possible to get some browser identifier installed? Maybe some installation ID, or something that helps me identify the client that is using my application?

Thank you.

In the C# in Assembly: System.Web has the class Request, that you can use to capture various information from Client.

For example the IP.

 String IP = Request.UserHostAddress;

See the Property list.

HttpBrowserCapabilities bc = Request.Browser;
Response.Write("<p>Browser Capabilities:</p>");
Response.Write("Type = " + bc.Type + "<br>");
Response.Write("Name = " + bc.Browser + "<br>");
Response.Write("Version = " + bc.Version + "<br>");
Response.Write("Major Version = " + bc.MajorVersion + "<br>");
Response.Write("Minor Version = " + bc.MinorVersion + "<br>");
Response.Write("Platform = " + bc.Platform + "<br>");
Response.Write("Is Beta = " + bc.Beta + "<br>");
Response.Write("Is Crawler = " + bc.Crawler + "<br>");
Response.Write("Is AOL = " + bc.AOL + "<br>");
Response.Write("Is Win16 = " + bc.Win16 + "<br>");
Response.Write("Is Win32 = " + bc.Win32 + "<br>");
Response.Write("Supports Frames = " + bc.Frames + "<br>");
Response.Write("Supports Tables = " + bc.Tables + "<br>");
Response.Write("Supports Cookies = " + bc.Cookies + "<br>");
Response.Write("Supports VB Script = " + bc.VBScript + "<br>");
Response.Write("Supports JavaScript = " + bc.JavaScript + "<br>");
Response.Write("Supports Java Applets = " + bc.JavaApplets + "<br>");
Response.Write("Supports ActiveX Controls = " + bc.ActiveXControls + "<br>");
Response.Write("CDF = " + bc.CDF + "<br>");

Answer 2

I found what I was looking for. I will use a technique based on Fingerprint with a plugin already made for such.

From N variables contained in the browser it is possible to generate a hash as a unique identifier for that machine.

I will also use the Evercookie to store the information.

I hope it helps.
