Unisys has developed a highly secure solution to meet the forensic integrity standards and policy requirements of several of the world's largest police departments. The secure storage of images and other multimedia content occurs in a tamperproof information archive, in effect, a digital evidence vault. Secure Image Management System (SIMS) technology uses advanced digital facial recognition technology to provide agencies with a 'digital vault' of stills and video data, the uses for which might include identifying deceased victims from tattoos or even from a decapitated head. Developed using Microsoft Silverlight, Unisys SIMS solution is a suite of products that permits the distribution, management and processing of images and multimedia in enterprise environments. Any law enforcement agency can implement SIMS to upload digital images from any source and securely archive the original in a digital vault. Police can then attach metadata tags such as case number, photograph time and date, photographer name to a working copy of the image to enable easy retrieval. Once the original image is uploaded, it can’t be modified or deleted.
