3.1i System Components: Images can be viewed over the network on approved PCs in the Department using DIMS®, the new DIMS® Browser software, or any database that is capable of viewing JPEG files. These image files have optimized compression, preset by the Administrator to match the network bandwidth, for distribution over the network. (Attachment#14) DIMS® can non-destructively enhance images by rotating, sharpening, adjusting brightness, darkening, or by the Linear "Shade" algorithm which brightens only the dark areas of an image using a histogram push process. Users cannot save these enhancements but the enhanced image can be printed or transmitted (emailed) if the Administrator has allowed them print and transmit permissions. (Attachment #15) 3.1i System Components: DIMS® incorporates multiple backup systems for hardware and software. Every image is stored in a Case directory Every image is stored in an Archive directory Every image is stored on a RAID 5 Array that is redundant and fault tolerant Every image is migrated to secure PDD WORM media Every hard drive in every system that could contain evidence is on mirrored RAID 1 drives Every image is stored in a secure encrypted format on every download station as a backup This proposal does include a provision for off-site storage equipment, (second PDD Digital Library), but does not include a pricing or provisions for a facility. Linear can provide pricing for private, secure, Underwriter Laboratories (UL) Approved off-site data storage on a monthly contract basis. 3.1k System Components: DIMS" utilizes Single DES encryption technology for transport of images over unsecured network lines or Internet. In addition to encryption, DIMS also utilizes SHA -1, MD5, and other HASH and checksum technology for authentication and validation of RAW file digital negatives and viewable JPEG images in order to preserve the integrity of digital photographic evidence. See 2.13.1 System Security 3.11 System Components: DIMS® automatically renames every digital asset downloaded into the system to maintain an identification that is unique. Files names are created in a format so that anyone can instantly identify Year, Month, Day, and Download Terminal ID for each image. Each filename also contains a four digit sequential number allowing for 9999 assets per day per download station. This is independent of the search and sort functionality of the DIMS® Database which is customizable and that can track a wide variety of user definable parameters including date of download.
