Importance of Authentication
Digital multimedia may be subject to accidental or deliberate modification, including tampering. The authentication process determines whether or not the multimedia recording in question has been modified. In the past, analog recordings were authenticated with processes akin to examining a bullet and the barrel it was shot from in that examiners looked for mechanical splices or overdubbing signatures in a physical master analog tape. In this age of digital multimedia, edits can be made and covered up very easily. There are free versions of editing software – such as Premiere, Audacity, and Hand-Brake, which are available online and can be used to make edits that alter the events or conversation that originally occurred in digital recordings.
Within the forensic and intelligence communities there is an increasingly large amount of multimedia data (meaning both video and audio) which has undergone various forms of trans-coding, whether it be: via internet transmission; moving from a proprietary format to an open one; uploading a file to a hosting site; using social media to post; uploading a multimedia file off of a phone; or intentional alteration/editing of files to change their meaning. If digital multimedia evidence is found to be altered, it could be ruled inadmissible in court because it is not an accurate representation of the events that occurred. Further if a decision regarding National Security must be based on the multimedia data, then those making the decision – and the community at large - must be aware of what the recording actually represents, or may not represent.
The community at large is seeking a solution to verify the content of multimedia files to better understand what is being portrayed. Such solutions are not only needed to examine individual files on a case-by-case basis, but also to perform automated analysis of large volumes of digital multimedia files in order to perform triage so that files may be subdivided into categories for further analysis, depending upon whether the automated techniques indicate modification or a lack thereof.
Example Approaches
Current approaches to digital multimedia file authentication rely heavily upon manual examination of the content and the digital file properties. These manual processes include the following: Use of a HEX editor to identify evidence of editing; Analysis of metadata to determine if there are any signatures associated with tampering or a lack of signatures expected in authentic files; the use of PRNU (Photo-Response-Non-Uniformity – i.e., noise signatures of the photos or videos); finding a control signal from an audio recording device; examining files for double compression (i.e. finding regions that appear to have been altered or audio components that emit a different noise signature); examine encoding characteristics, such as quantization tables, to verify the source of the recording throughout the entire recording. Likewise, for every type of multimedia, expert analysts can also perform time-consuming manual reviews of the content in order to detect irregularities associated with tampering.
Likewise, although automated techniques to detect double compression and some metadata signatures across large volumes of multimedia have been developed for some classes of digital multimedia files (i.e., digital photographs), for the most part, the community lacks automated tools to apply to the widest variety of digital multimedia file types.
