Discussions are underway between authorities and handset makers, an official of the Korea Communications Commission told AFP.
"We have recently started discussions with firms like Samsung, LG, Google and Apple regarding whether it's technically possible to disable those apps on their devices," the official said on condition of anonymity.
The move comes amid privacy concerns after a series of crimes involving men secretly taking photos of women.
While there is already a regulation in place making it compulsory for mobile phones to make a sound when a photo is taken there is no such rule for app developers, meaning there are dozens of apps that provide a mute switch.
In June, a man in his 30s was arrested in the southeastern city of Gimhae for secretly taking about 500 pictures under women's skirts by using a "silent camera" app.
South Korea has nearly 25 million smartphone users in a total population of almost 50 million.
