On the Reliability of Cell Phone Camera Fingerprint Recognition

Multiple multimedia forensic algorithms have been introduced allowing tracing back media copies back to its source by matching artifacts to fingerprint databases. While this offers new possibilities for investigating crimes, important questions arise: How reliable are these algorithms? Can a judge trust their results? How easy are they to manipulate? It has been shown that forensic fingerprints of digital cameras can be copied from one image to the next. Our aim is to develop new concepts for increasing the security of theses algorithms. In this work, we describe the state of our research work regarding attacks against forensics and provide an outlook on future approaches to increase their reliability.
