There are two articles(sorry they were both written in Chinese) better discussed about this issue, because even the lawyers in Taiwan can even explain this clearly.
There is no clear regulation of “portrait rights” in Taiwan; there is not even a thing called “portrait rights” in Taiwan.
Then the problem is, everyone is allowed to shoot photography freely; however, if there is any stranger in your photo, you are not allowed to sell or even publish the photos without agreements because they can claim their “portrait rights”.
The funny thing is, it is really hard to claim the “portrait rights”, but once the photographer take the photo of you, by weird law, the photographer is infringing the “portrait rights”???
I was doing research about “portrait rights” in Taiwan, there is no “portrait rights” in Taiwan, only human rights, and “portrait rights” is somehow linked, included, or related to human rights.
Not even the lawyers can give clear explanations or case examples about “portrait rights”, but the first linked article I posted above do give a clear case example about how unclear and how backward the “portrait rights” in Taiwan.
So what’s my recommendation? Just keep shooting~~~
