Dear Colleagues,

Given the everyday decreasing cost of digital imaging devices, there is a non-stop larger presence of digital content in people’s daily lives, not just as consumers, but also as producers. In fact, we are immersed in a massive explosion of digital media availability, which collaterally imposes the need for fast, reliable and inexpensive data origin identification or authentication. This fact is becoming more relevant considering
the daily increasing population belonging digital embedded cameras, such as smartphones, and producing and sharing media on the Internet. However, the existence of a larger community, comprises also an increasing number of situations of improper use. In this sense, researchers have shown a particular interest in the camera identification problem for forensic investigations, i.e., considering its utility as evidence or silent witness in court. While developing more robust solutions in real world scenarios is a must, criminals also become aware of image forensics possibilities, thus there is an additional need to cope with malicious  manipulation of images with the aim of spoofing sensor identification, i.e., to guarantee the sensor origin.

This Special Issue invites researchers to focus on this particular problem in the context of mobile devices defining state-of-the-art solutions for real-world applications, in the wild benchmarks, new applications, or critical surveys.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
