- Sometimes photos store the location where the photo was taken with the photo. This is called EXIF data. And then someone else could find out that info again. To avoid this, the best tip is to take a screenshot of a photo you want to use (e.g. on an advertising website) and then continue to use that screenshot. Fortunately, more and more social media do remove the EXIF data, but 'better safe than sorry' with something as important as your location.
- You can have a watermark put over the screenshot of your photo to try to prevent your photos from being used unwisely in other places (some dodgy ad platforms have nothing to be ashamed of). How? Type in watermark + how + your device (i.e.: watermark how android).
- Use Reverse image searchIf you suspect that a social media account (or a photo attached to a customer's Whatsapp account) is fake, you can often find out by uploading the photo to Google Images. Then you do a so-called "reverse image search," in which the search engine checks whether the image has also been used on other Web pages. For example, you can see if the same photo has been previously shared on someone else's Instagram account, for example. (Currently, Google Search has facial recognition turned off again).
- Ask yourself if you want to be on the site with a recognizable face. These days there is powerful facial recognition software available. With that, a picture of your face can be used to bring up other pictures to which your real name could be linked. You could also 'blur' (blurring). There are simple apps for that (search for 'blurring' in the Play store or the App store).
- Have you found your photos somewhere you don't want them? On that website, use the abuse or contact button and request removal.
- Sophisticated scammers use photos generated by a computer algorithm. These are images of non-real people, which means they were never online before and therefore cannot be verified via Google Images.
