With the development of multimedia editing tools, the contents can be more unperceivably and easily manipulated or tampered. Typically, a local content in an image can be copied and moved elsewhere in the same image, and it can even be pasted onto other images. Such skills are making the judicial use of multimedia proofs very difficult.
Blind multimedia forensics means the way of detecting the fake multimedia by analyzing the multimedia without much a priori knowledge of the manipulation methods used by potential fakers. It may also help to localize the tampering. The work is extremely challenging but urgently needed! To battle against faking contents, our group, with our cooperative team from Shanghai Jiao Tong University, has been developing an open platform for blind multimedia forensics for almost five years. Although the platform, named Bei-Shang Open Platform for Multimedia-Forensics (BOPM), is still in developing stage, we open it at the following link to gather feedback and seek investment or cooperation. People can first create an account and upload the suspicious files of images, videos, and audios in supported formats, one by one or in batch. And then he or she will acquire a forensic report about the media.
It must be stated that the platform is being used for scientific research at this time. It can be more or less useful but the forensic results can only be used as a kind of reference data or estimation. Even scientific ways of blind multimedia forensics might give only estimation.
