Abstract

The invention relates to an embeding immediate gained fingerprint watermark to digit image method and device and digital camera which can embed the fingerprint watermark to digit image and detect information of fingerprint watermark. The invention belongs to fields of digital image watermark technology. The picture took by the digital camera of the invention can check the perfectness and copyright. When the image is edit, updated, added and deleted, the changing of the image can be known by checking the perfectness, so the fidelity of the image can be realized, that digital picture is as electronic evidence is possible. At the same time, because the human original fingerprint is as the watermark information, the copyright information can be identified by extracting fingerprint watermark to achieve the effect of copyright identification.

Description

【Technical field】 [0001] The invention relates to a method and a device for embedding timely acquired fingerprint watermark information into digital images, and a digital camera capable of embedding fingerprint 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. For example, multimedia photos cannot be used as eviden...
