Abstract

The invention relates to a device embedding acquired iris watermark to the digital image. It adds a device for acquiring iris data and a watermark embedding device in the digital camera. Using the original iris of the photo taker as the watermark acquiring the digital iris information of the photo taker in the mean time of photo taking, to verify the copyright information. It will not affect the picture quality.

Description

【Technical field】 [0001] The invention relates to a device for embedding timely acquired iris watermark information into digital images and a device for detecting it, and also relates to a digital camera capable of embedding iris watermark information into photographs taken. The invention belongs to digital image watermark technology. 【Background technique】 [0002] A digital camera is a combination of mature digital technology and traditional cameras. Today, with the increasingly mature digital technology, digital cameras are favored by men, women and children because of their convenience, speed and fashion. Digital cameras take high-quality digitized images and allow you to quickly distribute them over a network or print them out on a color printer. While being convenient and fast, since digital photos can be easily modified and edited by various software, their copyright information and authenticity as photos are greatly discounted. [0003] At present, digital waterma...
