Detailed Description
The invention will be described in further detail with reference to the drawings and specific examples.
The invention mainly applies the digital watermarking technology to the mobile communication network, thereby providing effective copyright protection for the image or video data shot by the mobile communication terminal.
The invention provides a mobile communication system with digital copyright protection and authentication, which comprises a mobile communication terminal and a mobile communication network service system.
Referring to fig. 1, the mobile communication terminal includes a SIM card information reading module 1, a wireless communication module 2, a storage module 3, a camera 4, and a digital watermark loading module 5.
The digital watermark loading module 5 is realized by adopting a digital watermark technology. As known in the relevant art in the field, the Digital watermarking (Digital Watermark) technology is to embed an unobvious mark in the digitized data content. The embedded tokens are typically invisible or unobservable, but can be detected or extracted by computational operations. The watermark is tightly bound to and hidden from the source data, becomes an inseparable part of the source data, and can survive some operation that does not destroy the value of the source data for use or commercial use.
According to the purpose and technical requirements of information hiding, the digital watermark has the following basic characteristics:
a. the hidden (transparent) watermark information and the source data are integrated together, and the storage space of the source data is not changed; after embedding the watermark, the source data must not have obvious degradation; the watermark information cannot be seen or heard by a person, but only the source data.
b. Robustness (immunity, robustness) robustness refers to the ability of the data embedded with the watermark to undergo various processing operations and attack operations without causing the watermark information therein to be lost or destroyed. The processing operations include: the attack operations of blurring, geometric deformation, scaling, compression, format conversion, cropping, D/A and A/D conversion and the like comprise: lossy compression, multi-copy join attacks, shearing attacks, explanation attacks, and so on.
c. The security means that the hidden position and content of the watermark information are unknown, which needs to adopt a hidden algorithm and perform measures such as preprocessing (e.g. encryption) on the watermark.
The digital watermark loading module 5 can be implemented by hardware or software. The internal watermark algorithm can be divided into two categories according to the difference of the image space embedded by the watermark: at present, there are two main international implementation manners, namely, an LSB (least significant bit-bits) manner and a frequency domain transform coding manner.
And the digital watermark loading module 5 obtains the relevant information of the mobile communication terminal through the SIM card information reading module 1.
In the SIM card of the mobile communication terminal, the following key information is stored:
1, IMSI: international mobile registration identity information including a telecommunications country number, a mobile network number, a number of the mobile terminal in the mobile network.
TMSI: temporary mobile registration identity information.
LAI: mobile network location area information.
4. Telephone numbers, short messages, etc.
The digital watermark loading module 5 obtains the messages such as IMSI, LAI, system time and the like from the SIM card, arranges the messages, and modulates the messages as digital watermark information according to a certain message format. Since the digital watermark information is preferably not too long, only the two information, IMSI and LAI, and the system time message are selected.
In addition, lossless coding such as entropy coding can be performed on the information to reduce the length of the information if necessary. Therefore, the digital watermark loading module 5 is also provided with a pseudo-random generator therein, which is used for performing spread spectrum coding modulation on the digital watermark information.
The digital watermark loading module 5 is used for loading coded and modulated digital watermark information to image or video data shot by the camera device 4, the storage module 3 is used for storing the image or video data loaded with the digital watermark information, and the wireless communication module 2 is used for communicating with the mobile communication network service system to complete functions of communication, short message, mail receiving and sending, image receiving and audio/video data and the like of the mobile communication terminal.
Referring to fig. 2, the mobile communication network service system is divided into an application layer (network service layer), a control layer, a transport layer, and a radio access layer. Wherein,
the application layer comprises a value added network metadata base (Palay GW)6, a multimedia digital copyright authentication server 7 and a charging database 8.
The control layer includes a gateway GPRS (General Packet Radio Service) support node (GGSN)9, a Serving GPRS Support Node (SGSN)10, a home subscriber database (HLR)11, and a visiting location subscriber database (MSC/VLR) 12.
The transport layer is an ATM or IP based backbone switching loop 13.
The radio access stratum is a Radio Network Controller (RNC) 14.
The mobile communication terminal user 16 accesses the radio network controller 14 through the base station (Node-B)15, thereby communicating with the multimedia digital rights authentication server 7. In addition, the PC can also access the mobile communication service system through the Internet network and the gateway GPRS support node 9.
The multimedia digital copyright authentication server 7 is used for receiving a copyright authentication request and image or video data requiring authentication from the mobile communication terminal user 16, and analyzing and obtaining digital watermark information of the image or video data so as to perform copyright authentication.
The value added network metadata base 6 is used for providing the registration information of the user to the multimedia digital copyright authentication server 7 according to the received digital watermark information.
The home subscriber database 11 and the visiting place subscriber database 12 are used for providing the SIM card number of the mobile communication terminal which shoots the image or video data which requires authentication to the multimedia digital copyright authentication server 7 according to the received digital watermark information.
The mobile communication network service system performs data interaction with other data networks through the gateway GPRS support node 9, and the serving GPRS support node 10 is configured to record current location information of the mobile communication terminal 16 and perform transmission and reception of mobile packet data between the mobile communication terminal 16 and the gateway GPRS support node 9.
Referring to fig. 3, the present invention also provides a method for protecting and authenticating digital rights in a mobile communication system, which includes a digital rights information loading step a and a digital rights authentication step b.
When a mobile communication terminal user is using its camera to shoot image or video, the digital copyright information loading step a will be carried out.

The digital watermark information can be composed of IMSI, LAI and system time, and is processed by spread spectrum coding modulation. The method for coding and loading the digital watermark information can be consistent with the digital watermark loading algorithm of the picture or the video on the computer in the prior art.
When a mobile user receives an MMS (multimedia message) containing an image or a section of video data from another mobile terminal or a PC user receives the image or the video data shot by a mobile terminal from the Internet, a copyright authentication request can be initiated to the multimedia digital copyright authentication server of a mobile operator.
The digital copyright authentication step b specifically comprises the following steps:
