Social media is one of the popular computer-based technologies that facilitates communication between people and sharing information. According to statistics from eSafety commissioner, YouTube, Facebook and Instagram are the most popular social media services among Australian teens aged 13 to 17 years. Understanding the information we share, intentionally and inadvertently, and protecting the data is of critical importance. Users need to develop skills necessary to analyse the impact of their data traces.
Apps are usually developed for smart devices such as smart phones, tablets and televisions. Typically an app creates data movement between a local device and an application server, which can create security and privacy risks.
Other than the face in the image, the photograph does not have any identifying data on the surface. However, the meta data or Exchangeable Image File (EXIF) embedded into the file at the time the image was captured holds specific identifying and technical data. You can see from the screenshot the exact day, time and location as well as the file type and size. Various online tools are available to explore EXIF data but most social media platforms, such as Facebook, Instagram and Twitter strip the location data from an image. There are conflicting opinions around what happens with the data stripped by social media platforms and whether this process is done to protect the identity of the user, or to remove metadata which identifies ownership of the image. IPTC Photo Metadata strongly advocates against removing metadata and conducts and publishes the results of their Social Media Platforms survey outlining how various sites handle embedded metadata. Emailing or texting images will not remove sensitive data and could lead to a breach of digital privacy if sharing images
