Embodiment Construction

[0031] A kind of protection method suitable for multimedia data files in a portable system described in the embodiment of the present invention comprises the following steps: The computer device) performs safe processing on the multimedia files; downloads the processing results to the portable system side; and restores the multimedia files from the portable system side.

[0032] Secure handling of multimedia files on non-laptop computer systems includes:

[0033] 1. Determine the security level and cutting granularity of the original file:

[0034]Firstly, determine the security level of multimedia files. Different security levels require different cutting granularities, and set the parameters related to cutting granularity in multimedia processing software or self-developed software. For multimedia files with higher security requirements, the granularity of cutting them should be smaller; for those with low security requirements, in order to improve the efficiency of slice s...

Abstract

The invention relates to a protection method suitable for multimedia data files in a portable system, comprising the following steps of: performing safety processing on multimedia files at non-portable computer system terminals (for example, computer devices with high performance, including desktop computers, servers, working stations, high-performance embedded computers and the like); downloading the processed result in a portable system terminal; and reducing the multimedia files by the portable system terminal. The protection method has the beneficial effects that: a plurality of types and formats of multimedia files in a portable system can be efficiently protected, the safety degree is adjustable, the computation workload is low, and the cracking difficulty is high.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a protection method suitable for multimedia data files in a portable system. Background technique [0002] At present, the security of multimedia files in portable systems (hereinafter referred to as multimedia data files include image / graphic files, audio files, video files, etc.) ’s multimedia data files employ various protection measures to avoid data theft by malicious users. [0003] The Chinese patent application No. 200310111168.1 published in 2005 for the invention patent "Method and System for Segmentation, Storage and Restoration of Files" requires authentication codes including hardware serial numbers of storage devices, standard algorithm codes, etc. The host divides the file into two pieces according to the authentication code and stores them on two different storage devices; then use one host to restore the files on the two storage devices. Since the file ...
