Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the safe operation method of the digital signage system in the present invention is divided into the processing flow of the front-end management system and the processing flow of the terminal player. The following describes respectively: the processing flow of the front-end management system includes: a. inputting media content in the front-end management system, The media content can be advertising content or video content; b. Enter the key used to encrypt the media content, which is set and held by the administrator of the content management system. For example, the administrator sets the key to "12345678 "; c. calculate the encrypted character string through the encryption algorithm (such as the SHA1 encryption algorithm) on the media content; d. combine the encrypted character string with the media content, that is, append the encr...

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 [0001] The invention relates to the technical field of digital information security, in particular to a safe operation method of a digital signage system. Background technique [0002] In recent years, with the development of the economy, the vast number of enterprises have used advertising as the main means of product marketing, and the advertising media has also shifted from flat to three-dimensional, and from paper media to TV and Internet media. The digital signage system came into being under this trend. The digital signage system is a kind of content centralized management and maintenance, and the terminal advertising media operation and maintenance system presented by TV. [0003] The entire digital signage system consists of two major parts, namely the front-end management system and the terminal player. The front-end management system is responsible for content organization, production and management, and maintains the normal operation of the entire...
