Fig. 2 is an embodiment of the invention video telephone communication method flow schematic diagram.
Embodiment
Main thought of the present invention is: add distinctive digital watermarking feature in the distinctive call-information in video call, can extract evaluation to digital watermarking wherein whenever necessary, to reach the purpose of protection user profile.
Below in conjunction with the drawings and specific embodiments technical solution of the present invention is described in further detail.
Digital watermarking (Digital Watermarking) technology is with in the middle of some identification informations (being digital watermarking) embedding digital carrier, and does not influence the use value of original vector, also is not easy to be found out and revises once more.But can be discerned by producer and recognize.
Digital watermarking has following characteristics:
Fail safe: be difficult to distort or forge.
Disguised: digital watermarking should consciousness, and should not influence the normal use of protected data, can not degrade.
Robustness: be meant that digital watermarking still can the retaining part integrality also can accurately be differentiated behind the multiple signal processing that is not intended to or has a mind to of experience.
Watermark capacity: be meant carrier embeddable watermark information amount under the prerequisite that deformation does not take place.
Please refer to shown in Figure 1ly, is the composition module diagram of embodiment of the invention video telephone information protection terminal, and it comprises with lower module:
Digital watermark information generation module, digital watermark information merge module, digital watermarking extraction module and digital watermarking display module.
Described digital watermark information generation module major function is in conjunction with terminal information, has the extraction and the making of the digital watermark information of the peculiar information of terminal, and the watermark of generation offers merge module and uses.As digital watermark information, extraction and making are kept in the terminal in the time of can changing at the key message that terminal will be extracted, and have changed new SIM card such as terminal, and new number has been arranged such as the telephone number that can extract the calling and called mobile phone, air time stamp etc.; Also can before forming conversation, extract and make.
The watermark information that the digital watermark information merge module is responsible for the digital watermarking generation module is generated embeds in the key message of video telephone.The embedding of watermark can be after video call be set up, according to the watermark information that extracts and make,, embed in the key message of video call audio frequency and video by digital watermarking algorithm, embed by the time such as embedding visual telephone video key frame and audio frequency, the non-key frame of video can be not watermarked.Also can be watermarked when selecting to preserve call-information a side of conversation, before preservation, treat the key frame and the audio frequency embed digital watermark information of the video calling information of preservation.The embedding of watermark can not influence normal communication process and quality.
The digital watermarking extraction module then in needs, extracts reduction to the watermark that the digital watermark information merge module embeds again.By the digital watermarking extraction algorithm, can carry out the extraction of digital watermarking to the conversation on video telephone information of preserving, the digital watermarking that can extract audio frequency and video separately.After digital watermarking is extracted the telephone number, air time information etc. of visible both sides' conversation.This module can be made in the terminal, also can issue as the instrument of a digital watermark extracting separately
The digital watermarking display module is extracted by digital watermark extracting module and the watermark of reduction shows.Digital watermarking can show separately that after extraction a part that also can be used as video call information shows.This module and digital watermarking extraction module are similar, can be made in the terminal, also can issue as the instrument of a digital watermark extracting separately.
Please refer to shown in Figure 2ly, is the schematic flow sheet of embodiment of the invention video telephone information protecting method, and it comprises the steps:
S201: calling terminal A initiates visual calling as caller to terminal called B;
S202: the digital watermark information that extracts caller A;
Stab information and be stored in the buffer memory such as telephone number information, air time.
S203: terminal B answers visual calling, and this moment, both sides set up video call;
S204: the digital watermark information that extracts terminal called B;
Stab information and be stored in the buffer memory such as the telephone number information of terminal called B, air time.
S205: digital watermark information is embedded in the video call information;
Calling terminal A and terminal called B are in the visual information recording process, and the digital watermark information that terminal A and B are extracted merges, and adopt certain digital watermarking to embed algorithm, in the key message with the digital watermarking embedding video call that merges.Can select the Voice ﹠ Video key frame of video call to embed, to guarantee the robustness of watermark.In watermarked realization, can open up a block cache separately and handle watermark processing, embed in the watermark of buffering area individual processing, so just can guarantee the smoothness of video calling, speech quality is unaffected.Also can carry out during MPTY.
S206: preserve video call information;
No matter when terminal A or terminal B preserved the video call information of embed digital watermark, digital watermarking also together was saved in the video call information.
S207: if needed, can adopt the digital watermarking extraction algorithm, in the video call key message, extract the digital watermark information and the reduction that embed.
S208: if desired, can the digital watermark information that extract reduction be shown.
Certainly, in other embodiments, extract digital watermark information and show that digital watermark information can be placed on other devices and upward realize.
Technical solution of the present invention can be user both sides or in many ways in the process of video call, to the audio/video information embed digital watermark information that forms in the video call, be saved or intercept and capture as call-information, then the digital watermark information that embeds wherein also together is retained, identify or video telephone tracking of information etc. needs if any the video telephone of copyright, formation, can extract digital watermark information with specific extraction algorithm, thereby the responsible party is followed the trail of.
Described above only is preferred embodiments of the present invention; certainly can not limit interest field of the present invention with this; therefore; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
