Abstract
The present invention provides a method for enciphering multimedia information transmitted by a cell phone. A digital watermark addition module is arranged in a cell phone. After information which is transmitted is generated, the information is sent into the digital watermark addition module for carrying out adding digital watermark processing. The information added with a digital watermark is transmitted, which effectively controls the information which is transmitted. The copyright of the information which is transmitted is declared, or the flow direction of the information which is transmitted is controlled. Therefore, a relevant responsibility party can be traced.
Description
Technical field

Embodiment:
Embodiment below in conjunction with the digital watermark copyright protecting function of the multimedia messages that provides describes the present invention in detail.Shown in Figure 1 is to increase after the digital watermarking module, and multimedia messages enters module, interpolation watermark and the process of transmitting flow chart that adds watermark:
The present invention can comprise acquiescence watermark module is set, editor's watermark module (produces watermark keys, such as selecting text " Su Wei ", as watermark keys), with add in the watermark module (mainly comprising watermarking algorithm) one or several, can also comprise in case of necessity and remove the watermark module and extract in the watermark module one or more.
Some had appearred in the embedding algorithm about digital watermarking.Basic structure following (as Fig. 2):
Because internal memory is limited, the present invention can adopt the little and reasonable again algorithm of robustness of amount of calculation, such as:
Adopt DIGIMARC algorithm (being applied to Adobe Photoshop) for still image, perhaps adopting Wei is the algorithm that the people propose:
Referring to:
http://www.900.ibm.com/developerWorks/cn/security/se-eshow/#authorl。
Adopt people (A DWT-Based ObjectWatermarking System for MPEG-4 Video Streams such as Alessandro Piva for dynamic image, IEEE, 2000) or people (Evaluation of Watermarking Low Bit-rate MPEG-4 Bit Streams such as Adnan M.Alattara, SPIE, 2003) algorithm.
Such as adopting algorithm following (as shown in Figure 6):
1) will wait the to hide Info byte length of (watermark signal) writes in the reserve bytes of carrier image (shielded image) file header part;
2) watermark signal is converted into the binary data code stream;
3) with each byte of carrier image document image part high 7 successively behind the XOR again with above-mentioned binary number code stream XOR after the result write lowest order;
4) output watermark image data.
Beneficial effect of the present invention is, carries out method of encrypting by a kind of multimedia messages that mobile phone is transmitted is provided.So that the information of sending is effectively controlled, thereby realize grasping and controlling, and then realized tracking related responsibility side to the information declaration copyright sent or to the flow direction of sending information.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
