Embodiment 1

[0036] refer to figure 1 , which shows the flow chart of the first embodiment of the copyright protection method for electronic digital information of the present invention. In this embodiment, an encryption chip is used to encrypt the information on the electronic terminal. The embodiment of the method specifically includes the following steps:

[0037] Step 101: the electronic terminal saves the electronic digital information;

[0038] Step 102: trigger the encryption chip to encrypt the electronic digital information;

[0039] Step 103: the encryption chip decrypts the encrypted electronic digital information that needs to be displayed or meets the forwarding conditions;

[0040] Step 104: displaying the decrypted electronic digital information, or forwarding the decrypted electronic digital information meeting the forwarding conditions;

[0041]Wherein, the forwarding conditions mentioned above can be pre-set in the system or customized by the user; the forwarding condit...

Embodiment 2

[0045] refer to figure 2 , which shows the flow chart of the second embodiment of the copyright protection method for electronic digital information of the present invention, the embodiment of the method implements the encryption and decryption process of the information to be disseminated in software, specifically including:

[0046] Step 201: the electronic terminal sends an electronic digital information download request to the server;

[0047] Step 202: The server authenticates the electronic terminal, and if the authentication passes, go to step 203; otherwise, end the process directly;

[0048] Step 203: the server encrypts the electronic digital information with an encryption key;

[0049] Step 204: the server transmits the encrypted electronic digital information to the electronic terminal;

[0050] Step 205: The electronic terminal receives and saves the encrypted electronic digital information;

[0051] Step 206: The electronic terminal judges whether the above-m...

Embodiment 3

[0055] refer to image 3 , shows the flow chart of the third embodiment of the copyright protection method for electronic digital information of the present invention. In this embodiment, the electronic terminal includes an encryption chip, and the information to be transmitted is encrypted by combining software and hardware; the above-mentioned Encrypted information can only be read, modified, and forwarded after performing secondary decryption, which can further ensure the security of the information, ensure that only authorized users can process the above information, and provide a more reliable guarantee for the copyright of the information owner; this method Specifically include the following steps:

[0056] Step 301: the electronic terminal sends an electronic digital information download request to the server;

[0057] Step 302: the server encrypts the electronic digital information with an encryption key to generate first encrypted digital information;

[0058] Step ...

Abstract

The invention provides an electronic digital information copyright protection method and system as well as an electronic terminal. The method comprises: the electronic terminal transmits an electronic digital information downloading request to a server; the server encrypts the electronic digital information by use of an encryption key to obtain encrypted digital information; the server transmits the encrypted digital information to the electronic terminal; the electronic terminal receives and stores the encrypted digital information; and the electronic terminal determines whether to decrypt the encrypted digital information by use of a decryption key, and if yes, displaying the decrypted electronic digital information or forwarding the decrypted electronic digital information meeting a preset forwarding condition or a user-defined forwarding condition. Because the electronic digital information to be distributed or stored is encrypted by the encryption key, the encrypted electronic digital information has to be decrypted before being displayed for forwarded by a user, so that only the authorized user can process the electronic digital information, thereby protecting the copyright of the electronic digital information occupier.

Description

technical field [0001] The present invention relates to the field of electronic equipment, in particular to a copyright protection method and system for electronic digital information, and an electronic terminal. Background technique [0002] With the development of electronic technology, electronic digital information includes more and more rich content and more and more forms of expression, such as: various e-books, various office, pdf, text and other document files, various graphics, images, Animation, sound, video and other multimedia files, as well as various streaming media files, etc., have promoted the development of the electronic digital media terminal industry. Mobile terminals, PSP terminals, e-book readers, etc. that play audio and video files have rapidly expanded the consumer groups of electronic digital media. [0003] However, most of the existing electronic digital information is freely copied or downloaded from a network server. It is difficult to protect...
