Image management method based on mobile communication terminal

Abstract

The present invention relates to an image management method based on a mobile communication terminal, comprising the following steps: when receiving image information from the outside, receiving the image and temporarily storing it; inserting and using the inherent code of the mobile communication terminal into the temporarily stored image The step of generating the watermark; the step of storing the image with the watermark inserted. Use the inherent code of the mobile communication terminal to generate a watermark, and then insert it into the original image. When receiving a watermarked image, you can know whether it is an image with a watermark inserted using the inherent code through the correlation with the inherent code of the mobile communication terminal. It can decide whether to store or not, so that it can prevent the illegal misappropriation or dissemination of images. For the disseminated images, it can track the disseminators and curb the illegal dissemination.

Description

technical field [0001] The invention relates to an image management method based on a mobile communication terminal. In order to prevent illegal embezzlement or distribution of the image downloaded through the mobile communication terminal, a watermark generated by terminal inherent information is inserted into the downloaded image. Background technique [0002] With the rapid popularization of mobile communication terminals, the continuous emergence of various communication means, the increasing function of mobile communication terminals, the use of multimedia based on mobile communication terminals is increasing rapidly. [0003] The performance of the controller used in mobile communication terminals, the performance of the display unit, and the memory capacity have been rapidly improved. Currently, mobile communication terminals on the market have built-in cameras with a resolution of 2 million pixels or more, which can capture still images and moving images. , can use a...

Problems solved by technology

[0015] However, the above watermark insertion method is to insert copyright information into the corresponding image, so when a copyright dispute occurs, the original copyright owner can be effectively confirmed, but it is not a means to prevent illegal piracy and dissemination

That is, if it is impossible to know who distributed or misappropriated the corresponding image, it is impossible to know who to claim copyright, so this method has limited function of preventing the above phenomenon

[0016] That is, when using the conventional watermarking technology, it is impossible to fundamentally prevent the spread or copy between mobile communication terminals, and it is impossible to find the person responsible for the spread to an unspecified number of people through the Internet or the like.

[0017] As mentioned above, the images downloaded by mobile communication terminals in the past have the following problems, that is, due to the characteristics of digital works, they are easy to be disseminated or illegally embezzled, and it is difficult to protect copyright. Even if a watermark is inserted in the image for copyright protection, it is only It is only possible to know whether you have copyright, but it is impossible to prevent the transmission or copying between mobile communication terminals at the root, and it is impossible to find the person responsible for the spread to unspecified people through the Internet.
