Detailed description of the invention
Fig. 1 is the structural block diagram of the utility model；
Fig. 2 is the work flow diagram of the utility model.
Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
A kind of embodiment of the utility model is related to a kind of encrypted advertisements play system, as shown in Figure 1, comprising: decryption
Module, analysis module and playing module, the deciphering module utilize preset code key for reading ad data end signature
Ad data is decrypted；The analysis module is sent out if successful decryption to playing module for judging whether decryption succeeds
The instruction played out, if decryption failure or find it is not encrypted, to playing module issue forbid play instruction；The broadcasting
Module plays the ad data after decryption according to the instruction of analysis module.
In present embodiment, the encrypted advertisements play system further includes encrypting module, and the encrypting module is according to default
Secret key pair ad data is encrypted, can be using generating MD5 label after upsetting to ad data and special code key when encryption
Name to carry out enterprise-level encryption to ad data.Such as unencryption advertisement video data be 123456, to this 123456
(i.e. the data of unencryption ad data) and preset password 01001 (i.e. code key) are carried out upsetting calculating and be generated using MD5 algorithm
Specific signature ABC, and the signature of generation is added to the end of video data, to realize the process of encryption.It is being solved
When close, deciphering module can (and encrypting module be using identical according to the data and preset password 01001 of the advertisement video of unencryption
Calculation method) calculate a signature ABC, the signature arrived at this time is consistent with the signature at the advertisement video end read, then
Thinking legal allows to play.If the preset password of deciphering module is 10010, the signature arrived is ACB, the label arrived at this time
Name is inconsistent with the signature at the advertisement video end read, then it is assumed that and it is illegal, forbid playing.
It can be seen that the system of present embodiment is divided into fabrication and plays two parts, incited somebody to action in fabrication link by card reader
Program by encryption copies in storage card, and system is by upsetting each broadcasting ad data with code key before fabrication
Generate MD5 signature afterwards to encrypt；Verifying is decrypted by secret key pair ad data when playing, it is ensured that not encrypted is wide
Accusing data can not be played.The method that quick encryption has been used when encryption accelerates the speed of encrypting step, using to advertisement number
Come according to MD5 signature is generated after being upset with special code key to ad data progress enterprise-level encryption, irreversible after encryption, raising
The safety of ad data, it is ensured that advertisement machine will not play not encrypted ad data.
The working method of the utility model is as follows, as shown in Figure 2, comprising the following steps: (1) reads ad data, and benefit
It is decrypted with the ad data that default secret key pair encrypts；(2) judge whether decryption succeeds, after playing decryption if successful decryption
Ad data do not play ad data if decryption failure or finding not encrypted.
Specifically, need to encrypt ad data before playing advertisement, when encryption, using to ad data with
Special code key upset after generate MD5 signature comes to ad data carry out enterprise-level encryption, i.e., to ad data by with it is secret
Key generates MD5 signature after upsetting, and this signature is added to ad data end.When playing advertisement, need to pass through solution
Ad data is decrypted in close module, when decryption, first reads ad data end signature, according to (and the encryption of preset password
The same calculation method of module) calculate the signature, calculated signature and the signature at ad data end read are carried out pair
Than indicating that the ad data is legal and plays the advertisement, if the two is inconsistent if the two is consistent at this time, then it represents that this is wide
It accuses data and is not belonging to the data that the advertisement play system should play, the advertisement of prohibiting broadcasting.In addition there are also a kind of situations, i.e. advertisement number
According to not encrypted, it is being added after advertisement playing device or and current close that this indicates that the ad data is that criminal opens privately
