How to hide photos from the gallery and save it in my application

I am developing an Android application where he will select some photos from the gallery and hide them,

I can select a specific picture from the gallery and save it in my application and delete it from the gallery, but a person can see these photos if he opens my application folder in the SD card, so how do I store them so that even if the person checks my SD card, then he will not be able to detect these photos?
