Through the Looking Glass: Webcam Interception and Protection in Kernel
VIRUS BULLETIN www.virusbulletin.com Covering the global threat landscape THROUGH THE LOOKING GLASS: and WIA (Windows Image Acquisition), which provides a WEBCAM INTERCEPTION AND still image acquisition API. PROTECTION IN KERNEL MODE ATTACK VECTORS Ronen Slavin & Michael Maltsev Reason Software, USA Let’s pretend for a moment that we’re the bad guys. We have gained control of a victim’s computer and we can run any code on it. We would like to use his camera to get a photo or a video to use for our nefarious purposes. What are our INTRODUCTION options? When we talk about digital privacy, the computer’s webcam The simplest option is just to use one of the user-mode APIs is one of the most relevant components. We all have a tiny mentioned previously. By default, Windows allows every fear that someone might be looking through our computer’s app to access the computer’s camera, with the exception of camera, spying on us and watching our every move [1]. And Store apps on Windows 10. The downside for the attackers is while some of us think this scenario is restricted to the realm that camera access will turn on the indicator LED, giving the of movies, the reality is that malware authors and threat victim an indication that somebody is watching him. actors don’t shy away from incorporating such capabilities A sneakier method is to spy on the victim when he turns on into their malware arsenals [2]. the camera himself. Patrick Wardle described a technique Camera manufacturers protect their customers by incorporating like this for Mac [8], but there’s no reason the principle into their devices an indicator LED that illuminates when can’t be applied to Windows, albeit with a slightly different the camera is in use. -
Digital High Resolution Still Video Camera Versus Film- Based Camera in Photogrammetric Industrial Metrology
International Archives of Photogrammetry and Remote Sensing, Vol. 30, Part 1, pp. 114-121. DIGITAL HIGH RESOLUTION STILL VIDEO CAMERA VERSUS FILM- BASED CAMERA IN PHOTOGRAMMETRIC INDUSTRIAL METROLOGY Thomas P. Kersten and Hans-Gerd Maas Institute of Geodesy and Photogrammetry, Swiss Federal Institute of Technology ETH-Hoenggerberg, CH-8093 Zurich, Switzerland Phone: +41 1 633 3287, Fax: +41 1 633 1101, e-mail: [email protected] Phone: +41 1 633 3058, Fax: +41 1 633 1101, e-mail: [email protected] ISPRS Commission I, Working Group 3 KEY WORDS: close-range photogrammetry, high resolution, still video ABSTRACT In this paper a digital high resolution still video camera DCS200 and a conventional film-based small format camera Leica R5 are compared. The image data used for the comparison were acquired during several pilot projects in a shipyard. The goal was the determination of 3-D co-ordinates of object points, which were signalised with retro- reflective targets, for dimensional checking and control in the ship building industry, as well as to test the suitability of the cameras for these applications. The image point measurements in the photos taken by the film-based camera were performed on an analytical plotter, while the digital image data were processed semi-automatically with digital photogrammetric methods. In addition, some of the analogue images were scanned and then also processed with digital photogrammetric methods. The results of simultaneous camera calibrations and 3-D point positioning are given, showing its accuracy potential, which turned out to be in the range of 1: 50,000 and 1: 75,000 for the DCS200 and up to 1: 27,000 for the Leica. -

The H.264 Advanced Video Coding (AVC) Standard
Whitepaper: The H.264 Advanced Video Coding (AVC) Standard What It Means to Web Camera Performance Introduction A new generation of webcams is hitting the market that makes video conferencing a more lifelike experience for users, thanks to adoption of the breakthrough H.264 standard. This white paper explains some of the key benefits of H.264 encoding and why cameras with this technology should be on the shopping list of every business. The Need for Compression Today, Internet connection rates average in the range of a few megabits per second. While VGA video requires 147 megabits per second (Mbps) of data, full high definition (HD) 1080p video requires almost one gigabit per second of data, as illustrated in Table 1. Table 1. Display Resolution Format Comparison Format Horizontal Pixels Vertical Lines Pixels Megabits per second (Mbps) QVGA 320 240 76,800 37 VGA 640 480 307,200 147 720p 1280 720 921,600 442 1080p 1920 1080 2,073,600 995 Video Compression Techniques Digital video streams, especially at high definition (HD) resolution, represent huge amounts of data. In order to achieve real-time HD resolution over typical Internet connection bandwidths, video compression is required. The amount of compression required to transmit 1080p video over a three megabits per second link is 332:1! Video compression techniques use mathematical algorithms to reduce the amount of data needed to transmit or store video. Lossless Compression Lossless compression changes how data is stored without resulting in any loss of information. Zip files are losslessly compressed so that when they are unzipped, the original files are recovered. -
The Leica Dicomar Lens on the UX Cameras the New AG-UX90 and AG-UX180 Camcorders Are Large-Sensor General-Purpose Professional C
The Leica Dicomar Lens on the UX Cameras The new AG-UX90 and AG-UX180 camcorders are large-sensor general-purpose professional camcorders, designed to deliver great footage regardless of the particular shooting scenario, whether the user is tasking it with shooting sports, or news, or live events, or concerts, or conventions, or speeches, or commercials, or corporate films, or weddings, or interviews, or any of the myriad other situations professional shooters find themselves in. An absolutely key component of being able to tackle so many different types of shooting environments, is the lens. While many shooters have come to rely on large-sensor cameras such as DSLRs, DSLMs, and digital cinema camcorders, the limitations of the lens for these large-sensor cameras has always introduced complications or limitations in shooting style as compared to the small- sensor all-in-one camcorder designs of professional handheld camcorders. With the UX90 and UX180, Panasonic has set out to deliver a single-lens system that provides the quality, performance, and flexibility to let the camera excel in all these environments. Creating such a lens that could cover the relatively huge 1” sensor and 4K resolution was a significant task; getting it to do so with Leica Dicomar-certified performance was a significant accomplishment. Getting it to do so while actually delivering more capability, a wider field of view, better image stabilization, better autofocus, and a longer zoom range, is truly impressive. In this paper I’d like to explore what they’ve accomplished, how they approached it, and what these innovations mean for the typical shooter. -

Video Camera Buying Guide-OSU.Pages
Video Camera Buying Guide For dancers by Mitchell Rose Some people have been asking me for advice on purchasing a video camera. It can be pretty overwhelming out there with all the options available. It's hard to say, "Buy this camera" because the manufacturers change their model lineups every six months. But I can tell you some things to look for so you can scan the specs of a camera and make an informed decision yourself. ! Body Type: Camcorder or DSLR If you ask a filmmaker what type of camera to get, they're probably going to tell you to get a DSLR (digital single lens reflex) like in the photo at right. These are digital still cameras that also record video. Filmmakers love these because the image is gorgeous—they have a very filmic look. The sensor is large so you get great video. And, for the image quality, they're relatively inexpensive. I'm going to tell you: don't do it. One of the reasons filmmakers like them is they have a narrow "depth of field," meaning only the subject is actually in focus—everything else is blurry. This is the look we're used to in films. It drives the eye right to the point of interest. In a dialogue scene in a movie, that's fine—watch the couple talk, keeping them in focus, and let the Eiffel Tower in the background stay soft. But in dance you have people in the foreground and people in the background. Do you really want one dancer in focus and the other soft? You're also going to have people moving towards and away from the camera quickly. -
