Quick Setup - Persona. Adding the Persona login system to your site takes just five steps: Include the Persona JavaScript library on your pages. Add “login” and “logout” buttons. Watch for login and logout actions. Verify the user’s credentials. Review best practices. You should be able to get up and running in a single afternoon, but first things first: If you’re going to use Persona on your site, please take a moment and subscribe to the Persona notices mailing list.
Step 1: Include the Persona library Persona is designed to be browser-neutral and works well on all major desktop and mobile browsers. In the future we expect browsers to provide native support for Persona, but in the meantime we provide a JavaScript library that fully implements the user interface and client-side part of the protocol. Once this library is loaded in your page, the Persona functions you need (watch(), request(), and logout()) will be available in the global navigator.id object. Suppressing Compatibility Mode For example: API for .NET. How it works Integrating VouchSafe into your .Net website is very easy with the help of the VouchSafe .Net API: Create an account and register your domain with us to get a public / private key pair for your website.Add a reference to VouchSafeAPI.dll into your projectAdd a <script> tag into the form you want to protect with VouchSafe and set its “src” attribute to the return value of the VouchSafe.GetScriptUrl method.In the code handling the form submission, call the VouchSafe.Validate method with the proper information.
Inspect the VouchSafeResponse object returned to determine if the visitor completed the challenge successfully and take action in consequence. You’ll find that setting up VouchSafe is virtually identical to integrating other key-based validation services like reCaptcha. VouchSafe Web Service You can access these methods directly if you care creating your own custom code. The VouchSafe API methods are discussed in more detail in the following section. VouchSafeAPI Methods or. Are You a Human replaces annoying CAPTCHAs with games. Websites need to verify that a visitor is a real person and not an automated bot. But the CAPTCHA test that they came up with — where you have to type in the word that you see in a blurry distorted font image — is extremely annoying and often leads to multiple failures. So a Detroit-based startup, Are You a Human, is replacing the CAPTCHA with simple minigames instead. It is releasing its human authentication tool, PlayThru, to help companies fight spammers and bots that have begun to circumvent CAPTCHAs.
Companies using it include Quicken Loans and Fat Head, and users have played nearly 2 million games to date. The term CAPTCHA was coined in 2000 by Carnegie Mellon University researchers who based it on the word “capture” and used it to as an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. On top of that, CAPTCHAs are frustrating to users who can’t discern the distorted text. With Are You a Human’s tool, companies can embed a simple game instead. Technical. Existing User Authentication Process The user clicks "Login". If the addon is not unlocked then it will prompt for the master password.
If it is unlocked it will skip this step. Foamicator fetches the authentication URL from the DOM. Foamicator retrieves the key pair for the domain from the database, decrypts them, and generates the client random value. New User Authentication Process Same as above up to number 15 except instead of retrieving the key pair a pair is generated, encrypted and stored in the database.
Key Storage The first time a login attempt is made the addon prompts for a master password. Security Considerations The Database The database should be safe and unusable without the master password to regenerate the encryption key. The Addon All of the Foamicator code is kept inside an annoymous function so that there is no publically accessible interface to the object. The Authentication Process The only permanant information that leaves the browser is the public key. ✔ AuthenTec Store. Janrain: User management platform for the social web. Across the Web. Authentication vs. Authorization. It is easy to confuse the mechanism of authentication with that of authorization . In many host-based systems (and even some client/server systems), the two mechanisms are performed by the same physical hardware and, in some cases, the same software. It is important to draw the distinction between these two mechanisms, however, since they can (and, one might argue, should ) be performed by separate systems.
What, then, distinguishes these two mechanisms from one another? Authentication is the mechanism whereby systems may securely identify their users. Who is the user? Authorization , by contrast, is the mechanism by which a system determines what level of access a particular authenticated user should have to secured resources controlled by the system. Is user X authorized to access resource R? Figure I , below, graphically depicts the interactions between arbitrary authentication and authorization systems and a typical client/server application.
