8. Human Identity: Tracking Anonymous Users Program Overview • On each page visited, track the URL • HTML5 Local Storage as primary storage • Cookies as secondary storage X.Commerce (eBay Inc.) http://www.x.com | @x_commerce

9. Tracking Anonymous Users with Local Storage var storeName = "visited"; if (typeof(localStorage) == 'undefined' ) { //Local Storage Not Available } else { try { var sites = localStorage.getItem(storeName); sites = (sites === null) ? window.location : sites + window.location; localStorage.setItem(storeName, sites + "|"); } catch (e) { if (e == QUOTA_EXCEEDED_ERR) { //quota exceeded } } }

10. Tracking Anonymous Users with Cookies function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for (var i = 0; i < ca.length; i++) { var c = ca[i]; while (c.charAt(0) == ' '){ c = c.substring(1, c.length) }; if (c.indexOf(nameEQ) == 0){ return c.substring(nameEQ.length, c.length); } } return null; }

11. Tracking Anonymous Users with Cookies var storeName = "visited"; if (typeof(localStorage) == "undefined" ) { var cookieVal = readCookie(storeName); var value = ((cookieVal === null) ? window.location : cookieVal + window.location); var days = 1; var date = new Date(); date.setTime(date.getTime() + (days*24*60*60*1000)); var expires = "; expires=" + date.toGMTString(); document.cookie = storeName + "=" + value + "|" + expires + "; path=/"; } else { //Use Local Storage }
