The goal of this project is to measure and study the diversity of web browsers and establish statistical profiles of browser fingerprints. All of the data for the project will be collected in an anonymized form which ensures that it is not Personally Identifiable Information*, nor otherwise likely to lead to the identification or tracking of any web users.
*Personally identifiable information (PII) is any data that could potentially identify a specific individual.
We are committed to protecting the privacy of visitors to our website. In this policy, "we" refers to the Inria researchers and students who are bound to keep information they receive confidential.
For the needs of the research project defined here, AmIUnique collects anonymous data about the configuration of computers, operating systems, browsers and plugins. If you click the "View my fingerprint" button, this type of information will be collected from your browser. Although these kinds of data may form a `fingerprint' that could in principle be combined with information about page requests and identifying details in order to track people's browsing habits, we will never do so.
The specific 'fingerprint' information we collect is :
In addition to these data, we collect several kinds of `housekeeping' information to assist us in analyzing the fingerprint data. The housekeeping information is :
Our practices and purposes for collecting these housekeeping records are discussed below :
AmIUnique sets a cookie that persists for 4 months for the purpose of determining how often browser characteristics change, and how often they stay the same, when a browser returns over time. If your browser is configured to accept cookies, and you return to AmIUnique several times, the cookie will be used to link the data from your visits together so that we can study the natural evolution of browser fingerprints. AmIUnique also stores a temporary cookie that persists for 5 minutes in order to avoid fingerprinting a user again if they revisit within 5 minutes. If you want to disable/enable browser cookies, click on the link below corresponding to your browser for instructions. You should be aware that entirely disabling cookies may block some interactive features on some websites (most notably, automatic logins).

AmIUnique logs IP address. This IP will allow us to collect a dataset about how often browsers that change IP address could have been followed using a fingerprint.
AmIUnique collects a "fuzzy" timestamp, rounded to the nearest hour, each time it is visited. This will be used to measure how fast browser fingerprints change, but for no other purpose.
We will analyze the collected data in order to establish what are realistic profiles for browser fingerprints. The purpose of this analysis is to set an automatic procedure to proactively diversify user platforms in a realistic manner. AmIUnique has no Third-Party Service Providers.
We may publish or share aggregated, statistical data from the AmIUnique project in order to facilitate privacy research, educate people about privacy problems, and to aid in the development of privacy-enhancing technologies. We have gone to great lengths to ensure that AmIUnique does not produce any records about anyone's browsing habits or the identities of any individual visitors, so we will never be in a position where we could share any such records.
In a general way, Inria commits to carry out technical and organizational means to protect all information we gathered against illegal or fortuitous destruction, fortuitous loss, alteration, diffusion or unauthorized access. Nevertheless, Inria shall be required to divulgate any information to comply with any applicable law or rules, or to respond to any administrative or judiciary order.
Although we make good faith efforts to store information collected in a secure operating environment, we cannot guarantee complete security. Information collected will be maintained for a length of time appropriate to the needs of this research project.
