Some years ago, I published an article in a Springer journal. However, when I accessed its online version today, I found out that the publisher has swapped my residential address for my correspondence address. Since I am the corresponding author and this information is public, I am concerned about my security. I have already tried contacting Springer to no avail.
How should I proceed in order to get this issue fixed?
Springer has a privacy policy. It seems to be largely based on the European Union's General Data Protection Regulation (GDPR).
According to XIV, point 2, you can request a removal of your personal data on specific grounds, e.g. because the data are not needed, or because you withdraw your consent. This seems to be the case with you.
You can contact their Data Protection Officer about that ([email protected]). Explain your situation and ask for the data to be removed.
The Data Protection Officer should react swiftly, as there might be grave legal consequences if they violate your data rights (at least if the EU's GDPR applies to your case).
I have the same situation with my email address being published on SpringerLink, and they agreed to remove it. I simply mailed the same person that I had contact with during the proof reading.
The usual process for Springer is to publish an additional paper titled "Correction to ..." (with the same authors) that explains what has changed about the original paper, and mark the latter with "A correction to this article is available". As in your case the original paper was not wrong and did not need to be corrected (in fact, it should not even be changed at all), I would insist on this not happening. Otherwise, the additional article would for example appear on your Google Scholar profile. In my case, Springer agreed to just remove my email address without an additional article after clarifying internally (but the change has not yet been made).
