Machine-to-machine (M2M) communications play an important role for applications that involve connections between a massive number of heterogeneous devices in home and industrial networks. For M2M networks, realizing low latency and high reliability is of great importance. In this paper, we show the great potential of polar-coded orthogonal frequency-division multiplexing (OFDM) to fulfill those requirements...
Secure biometric systems are designed to allow authentication without requiring a reference biometric sample to be stored in the clear at the access control device. Instead, a template extracted from the reference biometric is stored on the device. An enrolled user can be authenticated by the template combined with a legitimate test biometric. However, an attacker who infiltrates the device only discovers...
Multimedia applications today constitute a sizeable workload that needs to be supported by a host of mobile devices ranging from cell phones, to PDAs and portable game consoles. Battery life is a major design concern for all of these devices. Whereas both - the complexity of multimedia applications and the hardware architecture of these devices - have progressed at a phenomenal rate over the last...
We present a lightweight scheme for watermarking or annotating video clips with information describing the workload that would be incurred while decoding the clip. This information can be used at run time to scale the operating voltage/frequency of the processor on which the video clip is to be decoded. Our main contribution is a fast, low-cost bitstream analysis technique for estimating the decoding...
This paper presents a novel beat detector that operates in the Huffman coded domain of a MP3 audio bitstream. We seek to answer two main questions. First, whether it is possible to extract beats without even partial decoding of a MP3 audio. Second, how to construct a low complexity algorithm to detect beats for multimedia applications in small devices such as mobile phones, if the answer to the first...
