Problems solved by technology

This solution uses encrypted media file storage, a single encryption method that can be used immediately. Although the object of encryption and authorization is the media owner, it still cannot guarantee the ripping of media files, such as KK video recorders, audio recording software recording and other ripping tools. Once ripped, it is impossible to find the ripping person, that is, it is impossible to track the illegal distribution of media files

Embodiment 1

[0086] Please refer to Figure 2- Figure 5 , the present embodiment provides a copyright protection method for media files, which can effectively prevent the copyrighted media files from being arbitrarily disseminated, ensure that they are circulated within the authorized channels, and at the same time accurately locate the source of illegal ripping.

[0087] The method of the present embodiment may specifically include the following steps:

[0088] S1: According to the user's personal account information, the encryption key and identity identifier unique to the user are randomly generated.

[0089] Specifically, after the user completes the key personal account information in the process of applying for registration with the server, such as a uniquely identified mobile phone number, the server will randomly generate an encryption key uniquely corresponding to the user based on the user's personal account information, which is used to encrypt the media file in the future; This implem...

Embodiment 2

[0150] The present embodiment corresponds to example 1, providing a media file protection system, including the server and the first program; The first program can achieve the following steps when called by the processor on the server side:

[0151] According to the user's personal account information, the encryption key and identity identifier uniquely corresponding to the user are randomly generated;

[0152] After receiving a download instruction triggered by a user to a media file, the media file is encrypted using the corresponding encryption key of the user;

[0153] By steganography the corresponding identity identifier of a user is written to the media file.

[0154] The protection system further comprises a client and a second program, the second program can achieve the following steps when called by the client's processor:

[0155] The client receives an open instruction corresponding to the one media file;

[0156] The client attempts to obtain the encryption key corres...

Abstract

The present invention provides a method and system for copyright protection of a media file. The method includes: randomly generating an encryption key and an identity identifier uniquely corresponding to the user according to the user's personal account information; A download instruction; the server uses the encryption key corresponding to the user to encrypt the media file; and writes the identity identifier corresponding to the user into the media file through steganography. Locally, only the authorized user who downloads the media file can open the media file with its encryption key to realize the limitation of the transmission path; write the identity identifier of the downloading user into the file to be downloaded through steganography to realize the limitation of the transmission path track.

Description

Technical field [0001] The present invention relates to the field of information security technology, specifically speaking of a method of protecting copyright of media files and a system thereof. Background [0002] With the continuous development of the information society, the security of information has received more attention. Nowadays, the information circulation method of society is simple, and for some information that needs to be protected, such as copyright protection of media files, a perfect security protection system has not been established. People can easily steal the above information that needs protection by copying it and spread it, even if it is actively disseminated by legitimately identified personnel. This is not only detrimental to the interests of businesses, enterprises, individuals and even the country, but also detrimental to the formation of good social weathering. [0003] The present invention is described in relation to the copyright protection of m...
