Description

【Technical field】 [0001] The invention relates to a digital camera, in particular to a digital camera capable of embedding altitude 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 authenticity as photos is greatly discounted. [0003] At present, digital watermarking technology is a relatively effective method to prevent and identify malicious individuals or groups from copying and dis...
