    There is a website service here, when you upload a photo, they could determine if a photo is "originally" taken, instead of after transferring between different people and on different platforms.

    Here I have a question, what is the definition of a photo that is originally taken? what is the parameter we are normally using to determine if a photo file is an "original "photo?

    Do they rely on checking the size and the resolution of the photos?

    Could someone modify a photo to be an “original photo" that can cheat the system while he does not have the original copy?

    Why don't you ask the website that supplies the service?

    They don't tell.

    However, if I upload a camera photo that is not the original copy (probably those transferred from the device to PC by USB instead of sending through whatsapp or wechat and save it) it could detect and returns with error saying that it is not original. If I upload a camera photo that is original size transferred by USB it would be OK

    I don't know how they know if it's the original copy or not,....

    You can check the EXIF if they haven't tempered with that

    The better question is, does it really matter? ;)
