    How to Avoid Javascript Web Fingerprinting
    Tech

    Web fingerprinting is a covert form of tracking that takes place on the client-side of a browser. It’s used to identify a user’s browser and device, which can be used to track browsing habits and deliver targeted ads. Unlike cookies, web scrapers don’t need to be granted permission to use this type of tracking, and it’s harder for end-users to detect or opt-out.

    Fingerprinting works by collecting a list of browser attributes and hashing them to create a unique identifier for each user. The more attributes collected, the more accurate the fingerprint will be. The list of attributes typically includes top-level configurations such as software versions, extensions, cookie settings, and languages. But there are also advanced techniques that rely on high-entropy data like GPU rendering, system fonts, and network conditions to generate a highly detailed profile of a user’s browser.

    Best Practices for Implementing JavaScript Web Fingerprinting

    Using this information, sites can track the device, operating system, and screen resolution of a visitor. Then, they can tailor content to match the visitor’s device and preferences.

    Aside from ad targeting, fingerprinting can also be used to prevent bots from spoofing user agent strings. This type of spoofing is commonly used by fraudsters to trick website scrapers into believing they’re browsing on a different device. To combat this, researchers have developed an innovative technique that leverages GPU cache attacks to bypass Javascript fingerprinting.…

    Clearout – Email Validation Without Signup
    Tech

    Email validation without signup allows marketers to spot and remove bad or invalid addresses from their lists. This protects their email deliverability and boosts inbox placement, ensuring that their messages reach their intended audiences.

    The email verification process takes place both front-end and back-end. Front-end email verification involves an interface on your website or app where users can input their email address, typically as part of registration or subscription forms. This is where basic validation is carried out, such as checking for the existence of the @ symbol and domain, and the absence of invalid characters. Back-end verification involves the backend system generating a unique code or link that can be used to activate the user’s account. This step ensures that the email address is valid and has access to the associated account, as well as checking for duplicate entries in the database.

    Email Validation Without Signup: Tools for Quick and Easy Use

    A good email verification tool will check the syntax of an email address, but it will also go beyond this to verify that the email address actually exists and that the owner can receive emails. It will also check for duplicates in the list and other risks, such as disposable accounts or undeliverable addresses.

    Clearout real-time email validation uses a combination of these techniques to validate emails and prevent them from being added to your list if they aren’t valid. It is available as a REST API, JS widget, or WordPress plugin so that you can easily integrate it with your landing pages and forms.…
