Recently my paper is reviewed (by a professor from independent third party) and accepted by a journal. But, my employer allows me to publish this paper only without its name there.
Publishing house is expecting affiliation for each author, i.e. I can not leave affiliation as blank.
What should I write as the affiliation?
As noted by @mankoff in a comment on Does one need to be affiliated with a university to publish papers?, you can use "Independent Scholar":
Here is a recent paper published by someone affiliated as "Independent Scholar": dx.doi.org/10.1175/BAMS-D-12-00171.1
For completeness’ sake, I mention that another option would be to give your private address as an affiliation. Here is an example for this. Here is another one (affiliations are at the end of the paper)¹. This one only lists the city and country part of the address².
