Abstract
The invention relates to the technical field of digital information security, in particular to a safe operation method for a digital signage system, which solves the problem that the prior art can not protect a terminal player through an effective means so that partial illegal contents can be played. The technical scheme has the key points that: a media content is inputted in a front-end management system, a key is inputted, an encrypted string is acquired through an encryption algorithm, and the encrypted string and the media content are combined to form a new media content document; after the terminal displayer acquires the new media content document, the key is inputted to read the encrypted string, the encrypted string is calculated through the cooperation of the key and the encryption algorithm, and the key string and the encrypted string are compared; and if the key string and the encrypted string are consistent, the media content document is added into a play list, otherwise, the media content document is discarded. The method can effectively eliminate the playing of illegal contents and protect the terminal displayer, and is suitable for digital signage systems in various large places.
Description
Technical field
The present invention relates to the digital information safety technical field, relate to a kind of safe operation method of digital signage system specifically.
Background technology
In recent years, along with expanding economy, all the main means of advertisement as product marketing, advertising media also turns to solid from the plane, turns to TV and network media from paper media in vast enterprise.Digital signage system arises at the historic moment under this trend, and digital signage system is that a kind of content centralized management maintenance presents terminal advertisement medium O﹠M system with TV.
Whole digital signage system is made up of the two large divisions, i.e. front end management system and terminal player.The front end management system is responsible for the content tissue and makes and manage, and safeguards the normal operation of total system.Terminal player is connected with the Content Management maintenance system by network mode, and obtains media content from the Content Management maintenance system, then content play is presented, and mainly is presented on the LCD display device.
Digital signage system is widely accepted and adopts as a new advertising, comprises places such as airport, supermarket, megastore, subway station and railway station, has played great demonstration effect.But the protection to terminal player in traditional digital signage system is paid little attention to, and does not perhaps have safeguard measure at all, causes the part illegal contents also can play at terminal player.
Summary of the invention
Technical matters to be solved by this invention is: propose a kind of safe operation method for digital signage system, solving in the prior art does not have effective means that terminal player is protected, thus the problem that causes the part illegal contents also can play.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: safe operation method for digital signage system may further comprise the steps:
A. input medium content in the front end management system;
B. input is used for the key of encrypted media content;
C. by cryptographic algorithm media content is calculated the encryption word string;
D. will encrypt word string and media content makes up, form new medium content file;
E. terminal player obtains new medium content file;
F. the key among the input step b;
G. read the encryption word string in the new medium content file, and preserve;
H. utilize the key among the step f to cooperate cryptographic algorithm to calculate the key word string, and preserve;
I. whether the encryption word string among the comparison step g is consistent with key word string among the step h, is execution in step j then, otherwise execution in step k;
J. this medium content file is added playlist, in order to follow-up play;
K. abandon this medium content file, and provide prompting.
Described media content comprises ad content and movie and television contents.
The invention has the beneficial effects as follows: effectively stop the broadcast of illegal contents, the protection terminal player.
Description of drawings
Fig. 1 is a safe operation method flow diagram of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, safe operation method for digital signage system among the present invention, be divided into front end management system handles flow process and terminal player treatment scheme, explanation respectively below: front end management system handles flow process comprises: a. is the input medium content in the front end management system, media content can be ad content, also can be movie and television contents; B. input is used for the key of encrypted media content, and this key is provided with by the keeper of Content Management System and holds, and such as the keeper this key is set and is " 12345678 "; C. by cryptographic algorithm (as the SHA1 cryptographic algorithm) media content is calculated the encryption word string; D. will encrypt word string and media content makes up, promptly be to form new medium content file with encrypting the end that word string appends to media content.
The terminal player treatment scheme comprises: the e. terminal player obtains new medium content file, and the mode of obtaining can obtain from the front end management system by LAN (Local Area Network) or wide area network; F. the key among the input step b is such as above-mentioned " 12345678 "; G. read the encryption word string in the new medium content file, and preserve in order to than than usefulness; H. utilize the key among the step f to cooperate cryptographic algorithm (as the SHA1 cryptographic algorithm) to calculate the key word string, and preserve in order to than than usefulness; I. whether the encryption word string among the comparison step g is consistent with key word string among the step h, be then this medium content file to be added playlist,, otherwise just this medium content file abandoned in order to follow-up play, and provide prompting, such as " this document is illegal file ".So just finished protection, stopped the broadcast of illegal media content terminal player.
Claims (2)
1. safe operation method for digital signage system is characterized in that: may further comprise the steps:
A. input medium content in the front end management system;
B. input is used for the key of encrypted media content;

D. will encrypt word string and media content makes up, form new medium content file;
E. terminal player obtains new medium content file;
F. the key among the input step b;
G. read the encryption word string in the new medium content file, and preserve;
H. utilize the key among the step f to cooperate cryptographic algorithm to calculate the key word string, and preserve;
I. whether the encryption word string among the comparison step g is consistent with key word string among the step h, is execution in step j then, otherwise execution in step k;
J. this medium content file is added playlist, in order to follow-up play;
K. abandon this medium content file, and provide prompting.
2. safe operation method for digital signage system as claimed in claim 1 is characterized in that: described media content comprises ad content and movie and television contents.
