A US-based startup called Waldo wants to use facial recognition, GPS and time stamps to create a consolidated and complete repository of every image of you that has been used, shared or posted online.Whether taken by people you know or professional photographers, the app will use the search technology to track the images down. Any photos it finds are then dropped into an album in the app on your smartphone.As revealed in a MIT Technology Review report, Waldo has raised $5 million in funding in a round led by venture capital firm Upfront Ventures, and will be release as a free iPhone app initially.The app targets doesn't just want to create a consolidated list of every image of you posted in social media, it also wants to offer services such as professionals using the app to sell images to people they photograph at events.To get started with Waldo, consumers at events will be prompted to text a selfie to the shortcode “SELFIE” along with the event's hashtag. A photographer then takes photos at the event using their DSLR camera, and these are automatically uploaded to Waldo's cloud by way of a Wi-Fi-enabled SD card.Similar concepts such as the Facebook Moments app were hit by privacy concerns in certain locations, with the launch of the latter withheld in Europe.
