Embodiment

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0027] figure 1 It is a block diagram of an embodiment of the rich media creation and display system with copyright protection function of the present invention. like figure 1 As shown, the system includes a rich media creation device 100 and a rich media display device 200 , both of which are connected to a network 300 and can exchange data with the network 300 . Although connecting through a network is a preferred implementation of the present invention, in other specific implementations of the present invention, the rich media creating device 100 and the rich media displaying device 200 can also be directly connected and exchange data.

[0028] like figure 1As shown, the rich media creation device 100 includes a con...

Embodiment approach

[0041] As an implementation manner, the decryption key for decrypting the rich media resource is an encrypted key, and only the user information of the legitimate user of the rich media resource can decrypt the key. Preferably, the key is the same as the key used when the rich media resource is encrypted in the content encryption module 101 of the rich media creation device 100 . That is, when the symmetric encryption algorithm is used, the encryption key and the decryption key are the same, and the key is stored in the digital certificate. The key stored in the digital certificate is not a directly available key, but uses user information as The encrypted key is the encrypted key. Before using the key, the key needs to be decrypted according to the user information of the legal user, and then the encrypted rich media resource content is decrypted with the decrypted key.

[0042] In a specific implementation manner, the rich media resource is stored and processed in the form o...

Abstract

The invention discloses a rich media constructing and exhibiting system with the function of copyright protection, which comprises a rich media constructing device (100) and a rich media exhibiting device (200), wherein the rich media constructing device (100) comprises a content encrypting module (101), a right setting module (102) and a content issuing module (103), the rich media exhibiting device (200) comprises a content obtaining module (201), a right resolving module (202), a content decrypting module (203) and a content playing module (205), and the content playing module (205) can also comprise a watermark embedding module (206). According to the rich media constructing and exhibiting system with the function of copyright protection, the illegal propagation of the contents of rich media can be effectively prevented, and support can also be provided to the assertion of rights by means of a watermark detection technology after an infringement act occurs.

Description

technical field [0001] The invention relates to the technical fields of computer and communication, in particular to network transmission and display of rich media, in particular to a rich media creation and display system with copyright protection function. Background technique [0002] With the development of Internet technology, rich media content containing one or more combinations of text, pictures, sounds, videos, animations and interactive scripts widely exists on the Internet. Rich media has good interactivity and rich expressiveness. Therefore, all major media are choosing to use rich media to display their works. The main manifestations are: a large number of digital newspapers and periodicals on major websites on the Internet use rich media or content close to rich media; the education industry uses rich media to produce various teaching content with rich interactive capabilities. [0003] Since rich media is usually encapsulated by HTML specifications, most of t...
