The DW Tool embeds digital information (images, drawings, text, video, sound, etc.) imperceptibly within a carrier image

DW Applications

Information Hiding - embedding a secret message or image within a carrier image for secure storage or transmission
Tamper Detection - embedding fragile watermarks (that break when tampered) in critical digital files (legal documents, evidence, master copies, etc.) that are stored or transmitted
Image Tagging - embedding descriptive information (e.g., date, time, subject, location, digital signatures) within an image file for efficient and convenient storage or transmission
File Access Control - embedding access codes in image files to support automated access to multi-level security databases

Example - Information Hiding

Example - File Tamper Detection

CACI MTL's Advanced Digital Watermarking (ADW) Tool is Unique

Our watermarks are invertible (100% removable) making image tagging and file access control practical when the original carrier image must be fully recovered for analysis or processing.

ADW Features	ADW Benefits
Image Tagging - embeds any descriptive information (date, time, subject, location, digital signature, etc.) in an image as an invertible (removable) watermark	Efficient and Convenient - allows image files and their descriptive information to be transmitted and stored together, rather than separately
File Access Control - embeds secure access codes in image files as an invertible (removable) watermark	MLS Support - supports automated access to multi-level security (MLS) databases
Invertibility of Carrier Image - carrier images tagged with descriptive information can be restored to their exact original state (pixel by pixel) by simply removing the watermark	Unique Functionality - makes image tagging and file access control practical when the carrier image must be fully recovered for analysis or processing.
Tamper Detection - divides an image file into blocks and embeds a separate, fragile watermark in each block. Any manipulation of carrier image file will corrupt (break) one or more watermarks.	Ensures File Integrity during electronic transmission and storage Enables All Electronic Storage for archive files (rather than hard copy storage)
Triple Security - the embedded watermark Is imperceptible to the human eye Is accessible only with a deciphering key Can be encrypted (CACI MTL ADE) before embedding in carrier image	Secure, Low Profile - minimizes intruder awareness of sensitive information, allowing highly secure storage and transmission of information with minimum chance of detection or compromise
Storage - stores the watermark information in the least significant bits of the carrier file	Storage Efficient - requires data storage no larger than the original size of the carrier file
Execution Time - a 733 Mhz processor requires only 1-2 sec. to add/remove a watermark to a 315 x 350 pixel carrier image file	Fast - minimal impact on response time and throughput for large databases
Payload - the embedded watermarks can be any type of electronic file (image, drawing, video, sound, text, spreadsheet, database, etc.)	Versatile - handles a wide range of applications
Carrier Image - any popular format (BMP, JPG, TIF, GIF, etc.)	Versatile - handles a wide range of applications

ADW H/W-S/W Configuration - PC-based under any Windows O/S, written in C++ and Visual Basic
