I’m not a computer buff by any sense but I heard that if someone knows the software that guy use to blur it can also be used to unblur?
I’m probably talking out of my arse but maybe worth a check? |

There might be an extremely remote theoretical possibility if...
- The person has access to the original unedited photo
- they know what software was used
- they know exactly which type of blur was used in that software
- they can reverse engineer the blur algorithm
In practice its nigh-on impossible to exactly restore a blurred image. A blur results in pixels being recalculated & compressed. At best all you could do is use neighbouring pixels to approximate what the original pixel might have been. |

I would.
But for the sake of the exercise I would humour any method you think would be able uncover what pixels were previously underneath a sticker in a saved image. |

I would too.
Once you've applied a sticker to a photo, saved it as a jpeg and uploaded it to a website the original photo content behind that sticker is unknown should you attempt to download it. There's no means of you removing the sticker to see what was originally beneath as the data doesn't exist.

Once you've put a sticker over your picture or blurred your picture surely if you were to the 'screenshot' it that will conceal any details hidden behind the original even more? I'm no techie but I guess the more you can take things away from the original picture the better |

Yes this is the best way, edit the photo and then take a screenshot to remove any metadata. Theoretically it’s possible to remove the stickers if it’s saved as a layer, iPhone users can press to see the original photo, so it it still there. When you upload the photo to Fab I’m not sure if that info is uploaded. |

Android picture editing software also has a "view original" button, but you can only do this during edit-time. The moment the edit is saved, the image is "flattened" and the old data is lost. You don't even need to screenshot it afterwards.
I don't use iPhone so maybe it's different on that , but I'd imagine that if it's even possible for these default basic picture editing apps to save layer information inside a image (which is categorically NOT possible if saved as either a png, bmp or jpeg), the image format would no longer be compatible with anything other than the software used to edit it. |

"Thanks for all the advice guys"
We find it simpler to ensure our faces aren't in the original image- usually by cropping them out.
In cases where the head is in the frame, we use a sticker which adds to the theme of the image.
However, when the weather warms, our new set of pictures may feature us wearing masks instead. Just so we can maintain the humour element. |

Thank you.
I stand corrected and pleased to hear it. |
