Fingerprinting

Added a new experimental webGL challenge (cf screenshot below). The goal is to study its value:

• Study its uniqueness

• Study how/if it depends on the OS/browser/versions

Added new pages to visualize the (potential) correlation/relationship between several fingerprinting attributes.

For example, you can visualize the correlation between the WebGL renderer (linked to the user device GPU) and its OS on this page.

This is only the v0 of this feature. In the coming weeks, I plan to

1. Add more attributes;

2. Allow combination of attributes, e.g. screen width x screen height vs OS.

Emails

When you visualize the information about an email domain, you can now see all related email domains based on the DNS MX records. For example, for mailinator2.net it looks as follows:

In addition to searching email domains based on their name, you can now search email domains using their associated DNS MX records.

I also Improved email search performance as the database is growing:

• Search is not case sensitive anymore (to ease search on mobile that automatically adds the first letter upper case);

• Speed up the search of disposable email domains.
