Detailed Description
The invention will be further illustrated with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
One embodiment of the present invention relates to an encrypted advertisement broadcasting system, as shown in fig. 1, including: the system comprises a decryption module, an analysis module and a playing module, wherein the decryption module is used for reading the signature at the tail of the advertisement data and decrypting the advertisement data by using a preset secret key; the analysis module is used for judging whether decryption is successful or not, if decryption is successful, a playing instruction is sent to the playing module, and if decryption is failed or unencrypted, a playing prohibition instruction is sent to the playing module; and the playing module plays the decrypted advertisement data according to the instruction of the analysis module.
In this embodiment, the encrypted advertisement playing system further includes an encryption module, where the encryption module encrypts the advertisement data according to a preset key, and during encryption, the advertisement data and a special key may be scrambled to generate an MD5 signature to perform enterprise-level encryption on the advertisement data. For example, when the data of the unencrypted advertisement video is 123456, the scrambling calculation is performed on the 123456 (i.e., the data of the unencrypted advertisement data) and the preset password 01001 (i.e., the key), a specific signature ABC is generated by using the MD5 algorithm, and the generated signature is added to the end of the video data, so that the encryption process is implemented. When decryption is performed, the decryption module calculates a signature ABC according to the data of the unencrypted advertisement video and the preset password 01001 (the same calculation method is adopted by the encryption module), and if the calculated signature is consistent with the read signature at the end of the advertisement video, the signature is considered to be legally allowed to be played. If the preset password of the decryption module is 10010, the calculated signature is ACB, and the calculated signature is inconsistent with the read signature at the end of the advertisement video, the signature is considered to be illegal, and the playing is prohibited.
Therefore, the system of the embodiment is divided into two parts of card making and playing, wherein the encrypted program is copied in the memory card by the card reader at the card making node, and before card making, the system generates an MD5 signature by scrambling each playing advertisement data and secret key to encrypt the playing advertisement data; the advertisement data is decrypted and verified through the secret key during playing, and therefore it is ensured that the advertisement data which is not encrypted cannot be played. The method for quickly encrypting is used during encryption, the speed of the encryption step is increased, the advertisement data are encrypted at an enterprise level by adopting MD5 signature generated after the advertisement data and a special secret key are scrambled, and the encrypted advertisement data are irreversible, so that the safety of the advertisement data is improved, and the advertisement player is ensured not to play the unencrypted advertisement data.
Another embodiment of the present invention relates to an encrypted advertisement playing method, as shown in fig. 2, including the following steps: (1) reading the signature at the tail of the advertisement data, and decrypting the encrypted advertisement data by using a preset secret key; (2) and judging whether decryption is successful, if decryption is successful, playing the decrypted advertisement data, and if decryption is failed or no encryption is found, not playing the advertisement data.
Specifically, before the advertisement is played, the advertisement data needs to be encrypted, and when the advertisement data is encrypted, the advertisement data is encrypted at enterprise level by scrambling the advertisement data with a special key to generate an MD5 signature, that is, the advertisement data is scrambled with the key to generate an MD5 signature, and the signature is added to the end of the advertisement data. When the advertisement is played, the advertisement data needs to be decrypted through the decryption module, when the advertisement is decrypted, the signature at the tail of the advertisement data is read firstly, the signature is calculated according to a preset password (the same calculation method as the encryption module), the calculated signature is compared with the read signature at the tail of the advertisement data, if the signature is consistent with the signature at the tail of the advertisement data, the advertisement data is legal and the advertisement is played, and if the signature is inconsistent with the signature at the tail of the advertisement data, the advertisement data does not belong to the data which should be played by the advertisement playing system, and the advertisement is prohibited to be played. In addition, there is also a case that the advertisement data is not encrypted, which means that the advertisement data is the advertisement data added by a lawbreaker after opening the advertisement playing device privately or inconsistent with the current password and the calculation rule, the calculated signature is illegal (i.e. inconsistent with the signature of the advertisement data), at this time, the analysis module directly judges that the decryption is failed, and the playing module prohibits playing the advertisement.
It is not easy to find that the invention decrypts the encrypted advertisement by the decryption module, and plays the corresponding advertisement data only under the condition of successful decryption (namely, the signature calculated by the encryption module is consistent with the signature calculated by the decryption module, which is called as successful decryption), thereby putting an end to playing all illegal programs and improving the safety of the advertisement data.
