I'm trying to compile a list of information that is accessible via javascript such as:
- Geo-location
- IP address
- Browser software
- Exit location
- Entrance location
I understand that a user can alter any of this information and that it's reliability is purely trust related, but I am still interested in what other information can be mined from the client.
Don't forget about
- Screen Size
- Allowed Cookies
- Allowed Java
- Mobile or Desktop
- Language
And here is useful link with data-mining demo:
http://javascriptsource.com/user-details/browser-properties.html
Here is most of the information:
var info={
timeOpened:new Date(),
timezone:(new Date()).getTimezoneOffset()/60,
pageon(){return window.location.pathname},
referrer(){return document.referrer},
previousSites(){return history.length},
browserName(){return navigator.appName},
browserEngine(){return navigator.product},
browserVersion1a(){return navigator.appVersion},
browserVersion1b(){return navigator.userAgent},
browserLanguage(){return navigator.language},
browserOnline(){return navigator.onLine},
browserPlatform(){return navigator.platform},
javaEnabled(){return navigator.javaEnabled()},
dataCookiesEnabled(){return navigator.cookieEnabled},
dataCookies1(){return document.cookie},
dataCookies2(){return decodeURIComponent(document.cookie.split(";"))},
dataStorage(){return localStorage},
sizeScreenW(){return screen.width},
sizeScreenH(){return screen.height},
sizeDocW(){return document.width},
sizeDocH(){return document.height},
sizeInW(){return innerWidth},
sizeInH(){return innerHeight},
sizeAvailW(){return screen.availWidth},
sizeAvailH(){return screen.availHeight},
scrColorDepth(){return screen.colorDepth},
scrPixelDepth(){return screen.pixelDepth},
latitude(){return position.coords.latitude},
longitude(){return position.coords.longitude},
accuracy(){return position.coords.accuracy},
altitude(){return position.coords.altitude},
altitudeAccuracy(){return position.coords.altitudeAccuracy},
heading(){return position.coords.heading},
speed(){return position.coords.speed},
timestamp(){return position.timestamp},
};
visitor.js is a javascript library that provides information about the client.
Including:
- Continent, Country and city
- Date of last visit
- Referring website or search engine (including search term)
- Time spent on the website
- Browser and operating system
- IP Address
- Language
- Browser
- OS
- Screen size
And more.
Visitorjs might be very handy, it's not free however.
