70 -- AUTOMATED FINGERPRINT IDENTIFICATION SYSTEMS SOL DEA-97-R-0028 DUE 073197 POC Connie Jones, Contract Specialist, (202) 307-7804 The Drug Enforcement Administration (DEA) has a requirement for the acquisition of three types of automated fingerprint identification systems. Installation, remedial and preventive maintenance, and training shall also be provided. -- Various Quantities -- The DEA is seeking interested sources with the capabilities of supporting this requirement. -- The Government anticipates the award of a firm fixed price type contract. Multiple awards are possible. -- The acquisition of these terminals will allow DEA to access evidential information from Federal, state and local data bases. This information will increase DEA's ability to solve cases through the identification of fingerprints developed on evidence processed in the laboratory, and evidence recovered and processed at crime scenes. -- Systems MUST have one or more of the following characteristics: (1) Shall be compatible/interoperable with the multi-state Western Identification Network, Inc. Automated Fingerprint Identification System data base, AND comparable to the NEC AFIS21 NT Workstation. (2) Shall be comparable to the Printrak Latent Station 2000. (3) Shall be comparable to the Morpho FLEX SCAN Latent Entry Workstation (with remote communication). -- SPECIFICATIONS ARE AS FOLLOWS: (1) NEC AFIS21 NT Workstation (Equipment shall at least be in accordance with the following NEC LEXS-3 Specifications): Processor -- 486; Hard disk -- 40 MB minimum; Board -- IMPP 20 MHZ; Operating System -- MS-DOS; Display -- 17 in. color monitor, 640 x 480 pixels; Track type -- 2 buttons; Compact Scanner: Resolution -- 25.6mm x 24.0mm, 256 levels of gray (2) Printrak Latent Station 2000: Workstation is designed to perform latent scanning, image encoding, and review of latent search results; the scanner has 500 dpi resolution and captures images in 256 levels of gray, images displayed in 128 levels of gray, provides auto-calibration and interactive adjustments of iris, focus, and top/back illumination, aperture control which allow the operator to repeatedly capture the same image without moving the print to obtain the best possible image clarity for each portion, and image enhancement toolset which include side-by-side zoom, on-screen rotation, 2 multi-level on-screen contrast and brightness controls. (3) Morpho FLEX SCAN Latent Entry Workstation (with remote communication): Processor -- IBM RS 6000; Memory -- 64 MB; Storage -- 1 GB; Display -- 20" high resolution; Mouse -- 2 button; Scanner -- 600 x 1200 color scanner with 256 levels of gray. -- REQUIREMENTS OF LATENT ENTRY WORKSTATIONS: (1) Workstations are specifically maintained using the technology of each company. Each workstation shall include a central or control processor, a high resolution scanner and printer. Workstations from each vendor are only capable of accessing the databases specific to their technology. At a minimum, each workstation must have the software algorithm to access their specific database. (2) Additional requirements for remote access are:(a) Automatic and manual detection and plotting of minutiae from the fingerprint. Three different types of parameters are used, inasmuch as, each Vendor defines minutiae differently. (b) Manual editing of the automatically detected minutiae from the fingerprint. Three different types of parameters are used, inasmuch as, each Vendor defines minutiae differently. (c) Automatic and manual core/axis extraction from the fingerprint. Three different types of parameters are used, inasmuch as, two of the Vendors' algorithms are core/axis dependent. The other Vendor's algorithm is not dependent on core/axis but uses it when available. (d) Automatic and manual core/axis editing from the fingerprint. Three different types of parameters are used, inasmuch as, two of the Vendors' algorithms are core/axis dependent. The other Vendor's algorithm is not dependent on core/axis but uses it when available. (e) Skeleton Image. One Vendor requires a skeleton image of the ridges to detect the minutiae. Another Vendor require a skeleton image of the ridges and of the furrows between the ridges to detect the minutiae. A tracing of the skeleton image is required by one of these two Vendors. The remaining Vendor detects minutiae from the scanned image. Each Vendor's algorithm for this process is again unique to the individual Vendor. (f) Relationship between minutiae. Two of the Vendors require the relationship between minutiae for the match algorithm. These two Vendors define relationship in a different manner. A relationship matrix display is also necessary. The remaining Vendor relies on X coordinate, Y coordinate, and theta coordinate. (g) Digital image processing is necessary in each workstation. Although similar in nature, each Vendor applies the process in their workstation to accommodate their functions. Some of these are zone editing, zooming, trimming, defining the image quality, ridge counts, density handling, auto gain control for contrast stretching, histogram stretching for equalization of the image, nonlinear contrast adjustments, adjustments of gray density, and ridge counts using gray level differences and others. (h) Automatic fingerprint pattern type assignment algorithm. All three Vendors use different algorithm for this process, which is specific to their technology. (I) Algorithm to determine the quality of minutiae. This parameter is used in the search process by two Vendors. (j) Algorithm to determine if any ambiguous data has been detected in the process with the capability to display any error message associated with this process. (k) Algorithm to facilitate side-by-side review of images. This also includes display of minutiae points, ridge direction indicators, registration and ridge flow. Each Vendor accomplishes this in a different manner. (l) Algorithm to thin ridges for the purpose of elimination of irrelevant dots and short lines. Parameter for this process is different for each Vendor. (m) Communications modules supporting functions between the workstation and the host site agency for transmitting and receiving image data in the appropriate format for acceptance by the host computer database. These require descriptive data fields, multiple search parameters, and search priorities that correspond to the host technology. -- Any interested parties shall submit their capability statement, descriptive literature, and other supporting information to the Contract Specialist, identified above, within 15 days of this notice date in order to be considered. -- SIC Code 3571 applies.
