You realized a few days later that it was too much of a privacy give-away, and made the wise choice to switch to a new photo. Search engines and archive sites are continually indexing as much content as they can from the internet.
These sites retain cached copies of images and pages long after they are changed or erased at the original source.
Aliases and usernames have become a big part of our personal online presence, and we often feel tied to them when we register for new sites and services.
This can be a great was to build an online identity, but it can also make it trivial to tie our activity on various services together.
The photos are visually similar enough that the search engines’ algorithms can draw a connection.
This exists primarily to help out professional photographers and photo storage tools. Let’s look at some of the data hidden inside of it: Create Date : 20 Make : Samsung Orientation : Horizontal (normal) Flash : No Flash Focal Length : 4.3 mm GPS Position : 28 deg 21′ 27.100″ N, 81 deg 33′ 29.71″ W Even with location geotagging disabled in your camera settings, metadata still provides a tremendous amount of detail about you and your devices, and can even uniquely identify photos taken with your camera.(The use of photo editing tools also becomes blatantly obvious, which can be a cause for some embarrassment.) Ensure you remove identifying metadata from photos before posting them onto your dating profile.If I were forced to pick only one error which causes dating site members the most personal embarrassment over the long term, it’s forgetting this.If that professional headshot is still in a cache associated with your dating profile, he or she can use Tineye to match it to your corporate bio that shares the same photograph.If you’ve changed your username, he or she may be able to find the previous version.A few years ago, image recognition on a large scale was restricted to law enforcement and corporate security. Free services like Tineye and Google Images will search billions of indexed images on the internet for identical or similar pictures.This isn’t necessarily traditional hash or metadata specific – cropping or resizing an image is not a foolproof way to defeat this (as I show in the screenshot below, where Tineye and Google correctly identified my profile selfie which is substantially cropped on social media).performs a broader sweep of services for usernames only, immediately flagging services where a particular username has been registered.This is an easy way for someone with malicious intent to draw connections between a dating site profile username and your ‘real’ life, even if your profiles are correctly private or hidden.The second way your photos can betray your privacy is a bit more technical, but still terribly important to recognize.It has to do with hidden information, or ‘metadata’, which is tacked onto most pictures by phones, photo editing software, and digital cameras.
