Signum Technology Company (http://www.signumtech.com/index_ns.html) ---- This British company was established in 1997, the SURESIGN series digital watermark products developed mainly for digital photography, multimedia, network release, electronics Business and medical imaging. Signum Watermarking products include two series: SURESIGN Fingerprints and SuResign Fingerprint Detection. Among them, the SuResign FingerPrints series is a watermark embedding software, and the Suresign Fingerprint Detection Series is free watermark detection software. ---- SuResign Fingerprints series included digital watermark plug-in SURESIGNWRITER developed for Photoshop, Batch Watermarking Software SuResign Pro and Watermark Development Capsules SURESIGN SDK. ---- The Suresign Fingerprint Detection Series includes the watermark detection plug-in SURESIGN DETECTOR developed for Photoshop and the watermark detection plug-in for Netscape Navigator CyBersleuth. ---- SURESIGN Watermarking Products Allows users to embed the author identity and work identify two watermark information. In terms of image type, SURESIGN does not have special requirements, supporting true color, grayscale, and index image. In the storage format, SURESIGN supports a JPEG format that compresses less than 30. SuResign can also read watermarks from the scanned image of the print job.
---- 3. Aliroo Ltd. (http://www.aliroo.com) ---- The company was established in December 1993, mainly developing a variety of cryptographic network security products and digital watermarking software. ALIROO has reached a series of technical agreements with Digimarc, which developed digital watermark software Scarlets can directly use Digimarc's certification services. ---- Scarlet provides a so-called "descarring" function, and after confirming the user password, the watermark can be eliminated and the original image is restored. This feature is unattended in digital watermark products. ---- 4. Alpha Technology Company (http://www.generation.net/~pitas/) ----alpha company is a company specializing in computer graphics, image processing, computer vision, etc. Developing digital watermark products Eikonamark There are many features in technology, and it is very suitable for copyright protection of digital images. ---- Eikonamark solves the multi-image watermark problem, which can be added more than 50 different watermarks. Of course, each watermark will damage the quality of the image to a certain extent. Eikonamark also allows the image to be added to the JPEG format of the high compression ratio, and the original image is not required when decoding. ---- 5.Mediasec Technology (http://www.mediasec.com) ---- The company is a professional information hidden technology company, its development SYSCOP series products mainly facing digital watermark, concealed identification and concealment Communication. The most prominent feature of the SYSCOP series is to allow information to be hidden in various lengths in image (PPM / PGM / PBM, GIF, TIFF, and JPEG format) and video signals (MPEGI and MPEGII). ---- Syscop Series include Washing Development Kits SYSCOP API, Watermark Embedded Tools Syscop Writer, Watermark Batch Tools Syscop Batch and Watermark Reading Tools Syscop Reader, these products can be in Unix (Sun Solaris, HP-UX, SGI Irix) and Windows (NT 3.51, NT4.0, 95/98) Environment. For research software ---- There are many digital watermark software written for verification algorithms, some of which reflect very valuable design ideas, with high reference value. The following columns are several of the more typical software: ---- 1. STools (ftp://idea.sec.dsi.unimi.it/pub/security/crypt/code/tools4.zip) ---- S-Tools is a time (empty) domain digital watermark software, Support the digital image file in the .GIF format of the audio file and .gif, .bmp. S-Tools Processing 24-bit true color image is very fast, for index color images, according to user selection, can be restored to true color image processing or add watermark by cutting the number of colors. ----2. Hide and seek (version 4.1: ftp://ftp.csua.berkeley.edu/pub/cypherpunk/steganography/hdsk41b.zip) (version 5.) (http://www.rugeley.demon.co.uk/security/hdsk50 .zip) (Ver1.0 for windows95 version: http://www.cypher.net/products/) ---- Hide and seek is the time (empty) domain digital watermark software, which is more limit on the image, only The 256-color image can be handled, and the image size is limited to 320 × 320, 320 × 400, 320 × 480, 640 × 400, 1024 × 768.
