    We are undoubtedly living in an age where we are exposed to a remarkable array of visual imagery. While we may have historically had confidence in the integrity of this imagery, today's digital technology has begun to erode this trust. From the tabloid magazines to the fashion industry and in mainstream media outlets, scientific journals, political campaigns, courtrooms, and the photo hoaxes that ... View full abstract»

    The article explains how photo-response nonuniformity (PRNU) of imaging sensors can be used for a variety of important digital forensic tasks, such as device identification, device linking, recovery of processing history, and detection of digital forgeries. The PRNU is an intrinsic property of all digital imaging sensors due to slight variations among individual pixels in their ability to convert ... View full abstract»

    Given the ability of photorealistic computer graphics (photorealistic CG) to emulate photographic images, as seen in movies and the print media today, there is little doubt that uninformed viewers can easily mistake photorealistic computer- generated graphics for photographic images. In fact, there was already evidence 20 years ago that to the naked eye certain computer graphics were visually indi... View full abstract»

    Presents the evolution of file carving and describes in detail the techniques that are now being used to recover files without using any file system meta-data information. We show the benefits and problems that exist with current techniques. In the future, solid-state devices (SSDs) will become much more prevalent. SSDs will incorporate wear-leveling, which results in files being moved around so a... View full abstract»

    Contrary to popular opinion, the use of paper in our society will not disappear during the foreseeable future. In fact, paper use continues to grow rather than decline. It is certainly true that as individuals, we may be printing less than we used to. And the role of paper has been transformed from the archival record of a document to a convenient and aesthetically appealing graphical user interfa... View full abstract»

    The field of audio forensics involves many topics familiar to the general audio digital signal processing (DSP) community, such as speech recognition, talker identification, and signal quality enhancement. There is potentially much to be gained by applying modern DSP theory to problems of interest to the forensics community, and this article is written to give the DSP audience some insight into th...

    Looking at the different points highlighted in this article, we affirm that forensic applications of speaker recognition should still be taken under a necessary need for caution. Disseminating this message remains one of the most important responsibilities of speaker recognition researchers. View full abstract»

    With SoC systems, there is a growing need for modest performance, low-cost solutions that make minimum use of FPGA resources and make the most effective use of the features in an FPGA. For such systems, it can be undesirable to provide an entire digital signal processing (DSP) core either on the same die or in a separate package. This article contends that for products having such modest signal pr... View full abstract»

    Yogi Berra, the famous baseball catcher, is reported to have said, "It's tough to make predictions, especially about the future." My rejoinder to that is that making predictions isn't hard at all. It's just tough to make ones that turn out to be right. With these ground rules established, we will try to predict the future of signal processing, with the intent of being able to use those predictions... View full abstract»

    In this article, we present a novel long-period fiber grating (LPFG) biosensor that can employ the simple and cost-effective optical intensity-based signal process method instead of the complex and expensive optical spectrum-based method. The ionic self-assembled multilayers (ISAM) technique is utilized to immobilize a thin layer of biorecognition film on the surface of a specially designed turnar... View full abstract»

    Due to their resistance to quantized-coefficient errors, traditional second-order infinite impulse response (IIR) filters are the fundamental building blocks in computationally efficient high-order IIR digital filter implementations. However, when used in fixed-point number systems, the inherent properties of quantized-coefficient second-order IIR filters do not readily permit their use in narrowb... View full abstract»
