Alpha-Tech Ltd. (W)

Alpha-Tech is a research and development company specializing in digital image, multimedia, and video processing. Alpha-Tech has a number of watermarking technologies that can be applied to almost any type of digital media.

EIKONAmark

EIKONAmark is software for casting "invisible" watermarks on digital images and detecting these watermarks. EIKONAmark can be used for copyright protection and "ownership" recognition of digital images. A copyright owner can cast its ID number as an "invisible" watermark on any digital image. Later, he can examine whether a given image, which is suspected of being illegally copied, contains his own ID number, and use it as legal proof.

AudioMark

AudioMark is a software package designed for casting "inaudible" watermarks on digital audio and detecting them in case of controversial ownership. The primary usage of AudioMark is copyright protection and supply of ownership evidence for digital audio. A copyright owner uses a unique key to create an "inaudible" watermark on its audio files. Later, he or she can examine whether a given audio file, which is suspected of being illegally copied, contains his or her own watermark, and use it as legal proof.[1][2]

VideoMark

VideoMark is software for casting and detecting invisible watermarks on digital video for copyright protection. Watermarks correspond to specific ID numbers called watermark keys. Each copyright owner of digital video uses a private key to cast an invisible watermark. This watermark can be detected later by using the VideoMark and the correct watermark key without resorting to the original product.

VolMark

VolMark is a powerful and flexible software package for embedding and detecting three-dimensional watermarks on digital, grayscale, and three-dimensional images. It can be used for copyright protection of three-dimensional images. A copyright owner can embed a unique, personal key number as a three-dimensional watermark in digital three-dimensional images. The results of three-dimensional watermark detection can be used either for security applications or as legal proof.
