Metadata is information that adds value to other information. “metadata generally has little value on its own. The Australian National Data Service points out that: The possibilities of using metadata are multiple and varied. But even metadata enthusiasts like McCarthy admit that metadata can also become “a worst enemy”, and thus understanding it is crucial not only for people working with metadata, but also for the wider network of individuals and groups working on sensitive information. McCarthy calls metadata “a best friend, it helps with searching, it helps with indexing and with understanding the context of the information”. This highlights the almost omnipresence of metadata as well as the possibilities of working with it. This idiosyncrasy means that the data contained within all images taken with that device, data one would usually ignore and is invisible to the human eye, becomes a digital ‘finger print’ identifying all images taken with that particular CCD chip. He explains that all of these chips, known as Charge-Coupled Device (CCD) chips, basically light-sensitive circuits, come with minor factory flaws that are unique to the individual CCD chip. To illustrate this point, McCarthy describes a small chip contained within all digital cameras which tracks all the metadata of that device. #OFFLINE EXIF DATA VIEWER PDF#PDF files, images, word documents, all have some metadata associated with them unless it has been intentionally scrubbed.” Interview with Exposing the Invisible, Smári McCarthy, head of the technology team on the Organized Crime and Corruption Reporting Project, says that “every information source has metadata, sometimes it is very explicit, created as part of the documentation process of creating the data. Metadata is often called data about data or information about information. The only differences are in the content of the metadata, and how it refers to the ‘thing‘ being described.” Metadata is structured information that describes, explains, locates or otherwise simplifies the retrieval, usage or management of an information resource. It is possible to describe a file on a computer in exactly the same way asone would describe a piece of art on a wall, a person on a job, or a place on a map. Service provides the following definition: “Metadata can actually be applied to anything. Such multimedia-related metadata is also known as EXIF data, which stands for Exchangeable Image File Format. Similarly in the digital sphere, a digital image may contain information about the camera that took the image, the date and time of the image, and often the geographic coordinates of where it was taken. The small cards stacked in library drawers provide the title of the book, publication date, author(s) and location on the library shelves. Metadata can be understood as a modern version of traditional book cataloguing. We will then focus on exactly what metadata is contained within what format and introduce tools to extract, strip and add metadata. This guide looks at how metadata has been used to expose, protect and verify abuses and excesses of power. If you want other ways to cover your digital footprint, I've assembled a list of resources: via Google Doc or Pastebin.A guide that looks at how metadata has been used to expose, protect #OFFLINE EXIF DATA VIEWER DOWNLOAD#On a computer, download the zipped code, open the folder, and open index.html in a browser with the internet turned off.Īll processing happens directly in the browser- no information is stored or sent anywhere.īug reports or questions to: repo at /everestpipkin/image-scrubber ![]() This tool works offline: on a phone you can load the page or add it to the homescreen, then turn on airplane mode (or turn off wifi/data) before opening any pictures. The blur function runs on top of shuffled, noisy, upscaled pixels and is fairly secure but sensitive information should be covered with the paint tool. You can change your brush size via the slider. Dragging on the image will paint on or blur it. You can select between painting over the image or blurring it out. Maximum size is 2500x2500 pixels - larger images will be scaled down. The program will display the data it is removing.Ĭlick okay, and you can then save the scrubbed image by hitting save or right clicking on it and saving it. It will remove identifying metadata ( Exif data) from photographs, and also allow you to selectively blur parts of the image to cover faces and other identifiable information.Ĭlick or drag onto the open button to open a photograph. This is a tool for anonymizing photographs taken at protests. ![]()
