The IP address, on its own, should not considered PII. There was a ruling in Breyer vs. Germany that IP addresses can be considered PII – in certain circumstances. The case was brought against an ISP, and the court ruled that the company had enough correlating data at its disposal to make an IP address de facto PII for any of its customers. The court limited its ruling, saying that with just an IP address alone, the…

GDPR simply classifies "personal data" as any piece of information that can be used to identify an individual. A static IP used by one person could therefore be considered personal data while a public IP shared between thousands of people behind carrier-grade NAT would not. The problem is that you can't tell the two apart and decide when it's safe handle the IP.

Indeed. My dynamically allocated public IPv4 address, given to me by my cable company, has been the same for as long as I've lived here, over four years now.

Ironically, my IPv6 prefix can change several times a day...

I've been looking into GDPR and when a cookie consent is needed. In fact, there's no thing called "cookie consent". If you track a user, you have to get his consent before doing it, whether you use cookie consent or now.

Cookie consent is (mainly) a different EU directive and not part of GDPR. It will be newly regulated by the - long delayed - ePrivacy directive.

"Cookies are an important tool that can give businesses a great deal of insight into their users’ online activity. Despite their importance, the regulations governing cookies are split between the GDPR and the ePrivacy Directive." https://gdpr.eu/cookies/

I am curious, how are you going to unanonymise an IP to something that could have 255 combinations (and that's just if you drop that last part on an IPv4). Nevermind that an IP alone is not PII. How can you reverse something that has many possibilties?

>> IP alone is not PII It is in Europe, despite some regional rulings (Germany?). It is not considered PII in the USA.

IP addresses are also explicitly considered PII by California’s CCPA.

(o) (1) “Personal information” means information that identifies, relates to, describes, is capable of being associated with, or could reasonably be linked, directly or indirectly, with a particular consumer or household. Personal information includes, but is not limited to, the following: (A) Identifiers such as a real name, alias, postal address, unique personal identifier, online identifier Internet Protocol address, email address, account name, social security number, driver’s license number, passport number, or other similar identifiers.

GDPR states “For data to be truly anonymised, the anonymisation must be irreversible”. So dropping 3 digits is clearly not enough to anonymize PII, it’s more pseudonymization.

How can an IP address without the last 3 digits possibly ever identify someone? That surface area is just way too large.

By using other information to narrow the pool of possible people.

> If you track a user, you have to get his consent before doing it This would mean any server-side analytics (looking at access logs, which include IP address and user-agent) cannot be used for analytics or tracking, since there is no way for a user to give/deny consent to a page that already has logged information on them.

The reality is that GDPR is not strongly enforced at the moment. This is not uncommon for Europe and may be a cultural differences with other places.

Those who have the intent to comply and are at least complying in spirit are not at any legal risk. Attitude matters.

And the spirit is obvious: get consent if you enable a third party to unique identify a user in reality. I.e. if it's private data or if you enable correlation across websites.

It's correlating and sharing you need consent for. Don't worry about a server log.

It is not about what you make possible. It's about what you do. Technically any sysadmin can access some information they should not. It's unavoidable.

But that's quite a far way from commercially exploiting databases of people without their consent.

Honestly they should just ban the sale of personal information. Most internet marketing vendors are not actually in the business of selling personal data.

Now the good ones suffer because of the bad ones. And the bad ones either pretend they have consent or find a way to get it.

Cookies aren't regulated by the GDPR[0] but instead by the ePrivacy Directive.[1]

Article 5(3) of that directive states that

"Member States shall ensure that the use of electronic communications networks to store information or to gain access to information stored in the terminal equipment of a subscriber or user is only allowed on condition that the subscriber or user concerned is provided with clear and comprehensive information in accordance with Directive 95/46/EC, inter alia about the purposes of the processing, and is offered the right to refuse such processing by the data controller. This shall not prevent any technical storage or access for the sole purpose of carrying out or facilitating the transmission of a communication over an electronic communications network, or as strictly necessary in order to provide an information society service explicitly requested by the subscriber or user."

In other words, unless the cookies are strictly necessary to providing you with the service then you must provide users information about what the cookies are used for, and you must offer an opt-out.

(It's also worth pointing out the generality of this Directive, too: It doesn't only apply to cookies, but also to things like localStorage).

The ePrivacy Directive is, as its name suggests, a Directive which is addressed to member states of the European Union which have all written it in to domestic law.

In the UK, for example, it was implemented as PECR[2].

[0] The ePrivacy Directive does reference the old legislation that the GDPR replaces, so you should consider the reference in the ePD to Directive 95/46/EC as a reference to the GDPR. This means the standard of "consent" is the GDPR's standard now.

doesn't the GDPR protect against storing "Personally identifiable information"? Plausible does use the IP address for the visitor to create a unique visitor ID, but it does not store it, so I am not sure how can you use that information to link it to an individual.

The GDPR regulates the use of "personal data", which is broader in scope than "personally identifiable information":

"‘personal data’ means any information relating to an identified or identifiable natural person (‘data subject’); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person"

You obtain consent and then you log only if consent was provided. You can essentially use two logs, one for technical purposes (under legitimate interests you should be fine logging as long as those logs are only used for technical/debugging/abuse prevention purposes and the data is not kept for longer than necessary) and one for marketing/analytics purposes. You only log to the second one if consent has been given,…

It's also probably a legitimate interest to retain data for marketing and analytics purposes, so long as that retention meets the same sort of guidelines. Marketing is explicitly highlighted as one of the applicable uses for legitimate interest.

Have you any specific document or decision in mind ?

That is deterministic, but the key thing is that it is not reversible

Technically, you could enumerate all four billion IP addresses (multiplied by all common user agents) to reverse it. This is, however, prohibitively expensive for tracking, so I think it does the job.

Not without the salt, which they delete every day. Pretty much impossible.

I think that overall the GDPR law was good for privacy but a disaster for usability.

It was good for privacy, not because it's enforced or not and not because sites are showing cookie consents, but because it made the public more aware of centralization/privacy issues on the internet and companies a bit more careful with data processing. This law also resulted in many "privacy-friendly" alternatives for various services, which in the end led to a healthier market and improved data decentralization.
