Embodiment Construction

[0028] Such as figure 1 Shown, a kind of data security protection method of fusion media content file of the present invention comprises the following steps,

[0029] Step S101: Referring to the characteristics of the WEB application, write a template file according to the syntax of the WEB class description language. The WEB class description language divides the template file into three parts. The first part is the template identification part, namely URL, HOST, POST / GET content, which is obtained by analyzing the HTTP header of a certain type of WEB application data packet; the second part is the key content description Part, including keywords, the starting position of the key content in the data packet, and the length of the key content, obtained by analyzing a certain type of WEB application data packet; the third part is the data type, such as login, post, post, exit, etc., by Defined by the protocol developer.

[0030] Step S102: The system reads and parses each WEB ...

Abstract

The invention relates to the technical field of data security protection, in particular to a media content file fused data security protection method, which comprises the following steps of S101, grammatizing and writing into a template file according to a WEB class description language; S102, USING the system to read and analyze each WEB template, and form a linked list in a memory; S103, analyzing the HTTP protocol header in the WEB application; S104, searching a template in a template linked list by combining a character string multi-mode matching algorithm; S105, analyzing the HTTP data part according to a fixed format; S106, extracting contents corresponding to the keywords; and S107, formatting the decoded key content, and outputting the formatted key content. After the method is adopted, the method is suitable for various media contents, and the security of file data in media is protected.

Description

technical field [0001] The invention relates to the technical field of data security protection, in particular to a data security protection method for fusing media content files. Background technique [0002] Protecting the value of media content is one of the biggest challenges in media content delivery. Without proper protection, content owners, content providers and service providers are reluctant to distribute their valuable media content. In the past, digital rights management was widely used for content protection. Valuable media content is encrypted using a cryptographic format in order to prevent unauthorized access to the media content. Only those with appropriate permissions to the media content can decrypt and access it. [0003] However, DRM is a passive content protection scheme that can effectively protect media content only when it is in an encrypted format. When the media content is decrypted or in its native format, the protection is lost. In its nativ...
