Annotation: This article describes the DCS 121 system that provides photographs and image authentication, aiding forensic scientists in solving crimes.
Abstract: DCS 121 is a system that uses digital photography in conjunction with techniques to enhance digitally captured images, thereby creating better identification evidence. This system provides forensic scientists with the ability to photograph evidence, secure and authenticate original digital images, and enhance working copies of images to extract important information that can potentially solve a crime. The DCS 121 is manufactured by Mason Vactron of the United Kingdom. It consists of a line-scan digital camera with a workstation for recording and printing forensic evidence. The digital camera is capable of capturing high-resolution images in 50 seconds at 16.8 million-pixel resolution. The image authentication software is VeriData from United Kingdom-based Signum Technologies Ltd. which provides a fast, simple, and effective means of image authentication and file management. The DCS 121 preserves the integrity of evidence by automatically tagging images with an invisible watermark that provides proof of authenticity. The system creates better identification evidence, making it easier to secure convictions.
