Fig. 7 is a flowchart illustrating interaction between a terminal and a server in a method for playing media data according to an embodiment of the present application. Referring to fig. 7, the embodiment includes:

step 701, after the first terminal receives the trigger instruction, the first terminal generates a second count value based on the stored first count value and a preset algorithm, and stores the second count value.

Wherein the second count value is different from the first count value.

In implementation, a user clicks a switch of the peripheral card to electrify the peripheral card, the peripheral card inputs a first count value pre-stored inside into a function for increasing a preset increase value to perform calculation, so as to obtain a second count value, for example, the first count value is 0, the preset increase value is increased to 1, the first count value 0 is input into the function, a second count value 1 is obtained through function operation, and then the obtained second count value is stored to cover the first count value.

Step 702, the first terminal generates an audio signal carrying the pre-stored authority identifier and the second count value.

The peripheral card generates an audio signal through a conversion function, wherein the conversion function can be the corresponding relation between the first 16 bits in the ASCI I code and the audio frequency, each audio frequency is the only one audio frequency in the range of 18kHz-22kHz, namely the conversion function is the corresponding relation between the audio frequency and the characters.

In an implementation, the peripheral card first generates a digest value based on the pre-stored authority identifier, the second count value and the pre-stored key, and the method may process the following steps:

firstly, the peripheral card performs initial digest value calculation, the step can be performed through an SHA256 algorithm, and the peripheral card inputs the authority identifier, the second count value and a pre-stored key into the SHA256 algorithm to obtain an initial digest value with 32 bits.

And step two, the peripheral card shortens the calculated initial digest value to a digest value with a uniform preset length, the step can be carried out through an MD5 message digest algorithm, and the peripheral card inputs the initial digest value obtained in the step into an MD5 message digest algorithm to obtain a digest value with a preset length of 16 bits.

Secondly, the peripheral card randomly orders the abstract value, the second count value and the authority identifier and generates corresponding sequence information, and the specific processing can be as follows:

after the abstract value is obtained, three sections of character strings to be processed, namely the abstract value, the second counting value and the authority identification, are stored in the peripheral card, the three sections of character strings to be processed are randomly sequenced to generate a sending queue, the sending queue is a queue for finally inputting a conversion function, and the sequence of all the character strings in the sending queue is recorded as another section of character string, namely sequence information.

Then, the peripheral card generates an error correction code based on the digest value, the second count value, the authority identifier, and the final arrangement order of the order information, and the specific processing may be as follows:

after the order information is obtained, it may be placed at the forefront or the rearmost in the transmission queue. The peripheral card generates an error correcting code based on the four-segment character string of the transmission queue, the generated error correcting code can be a hamming error correcting code, and the generation of the hamming error correcting code firstly needs to calculate the number of the error correcting code according to the binary digit number of all characters in the transmission queue and the preset binary digit number of the transmission queue. And secondly, finding the position of the power of 2 n in the binary digits of all characters in the transmission queue as the insertion position of the error correcting code. Each error correcting code detects the character 2 power of n-1 before the error correcting code to obtain the parity of the part, and repeats the operation to obtain all the error correcting codes and stores the error correcting codes in the queue.

After the sending queue is subjected to the operation, the peripheral card inputs the sending queue into the conversion function to obtain a section of audio signals composed of different audio frequencies, and the peripheral card sends the audio signals outwards.

Step 703, the first terminal sends out an audio signal to the outside.

In the implementation, the peripheral card plays the audio signal of 18kHz-22kHz which can not be heard by human ears through a loudspeaker on the peripheral card, so that the influence of noise in the environment on the audio information is reduced as much as possible.

Step 704, the second terminal obtains the digital information carried in the audio signal.

The digital information includes the right identifier and the second count value, and may further include the digest value and the sequence information, and may further include the error correction code.

In implementation, a user opens a music player in a mobile phone to log in an account, then enters a monitoring interface, the music player enters a monitoring state, the music player receives an audio signal sent by an external card, records the audio frequency of the received audio signal, namely records the audio signal as digital information, and sends the recorded digital information and the account to a server.

Step 705, the server receives the digital information sent by the second terminal.

In implementation, the digital information is sent to the server, and the specific processing may be as follows:

firstly, a server receives digital information and an account number sent by a second terminal, the server extracts the account number from all received contents, the rest contents are the digital information, the digital information is recorded in the form of audio frequency, the rest digital information is input into a conversion function, and the server analyzes the digital information into a binary character string according to the corresponding relation between the audio frequency and characters in the conversion function.

And step two, after the character string is obtained, the server corrects errors according to the error correcting codes, divides the characters covered by each error correcting code into one group, and performs logic exclusive-or operation on all the groups, wherein if the operation results of all the groups are 0, the character string has no errors, if the operation result of one group is 1, the character string has errors, and if the results of the groups are wrong, the characters covered by the groups at the same time have errors, and the errors can be corrected by negating the characters with errors. The corrected character string may include the authority identifier and the second count value, and may further include the digest value and the sequence information.

Step 706, if the legal authority identifier stored locally in the server includes the authority identifier in the digital information, and the second count value satisfies the preset condition relative to the first count value, the playing address of the media data corresponding to the pre-stored authority identifier is obtained.

Wherein the preset condition is set before executing the scheme.

In implementation, the server obtains a correct character string after error correction, then obtains a digest value, a second count value and an authority identifier according to sequence information, and respectively checks the three sections of characters, firstly checks whether the authority identifier is the correct authority identifier, then checks whether the second count value of the terminal is greater than the first count value of the server, and finally checks whether the digest value is the same as the digest value calculated by the server.

After the verification, whether the peripheral card is legal or not can be judged, whether the sound signal is correct or not can be judged, whether the secret key is correct or not can be judged, after the verification is completed, the server verifies whether the authority identification in the list stored in the database is bound with the account number or not, if the account number is not bound, the corresponding peripheral card can be known to be used for the first time, the account number is bound to the authority identification, namely, the account number is added to the corresponding position in the list shown in the figure 8, the second counting value of the terminal is assigned to the first counting value of the server, meanwhile, the server can obtain the sales volume of the digital album based on the number of the bound authority identification and the account number, and the server can also add one to the sales volume of the digital album when the authority identification and the account number are timed.

Step 707, the server sends the play address of the media data corresponding to the permission identifier to the second terminal.

In implementation, after the server completes the above operation, the server sends the play address of the digital album corresponding to the authority identifier in the list to the mobile phone. If the account number is bound, the corresponding peripheral card is known to be not used for the first time, and the playing address of the digital album corresponding to the authority identifier is directly sent to the mobile phone according to the list.

In step 708, the second terminal receives the play address of the media data sent by the server, and plays the media data based on the play address.

In implementation, when the mobile phone receives a play address of a digital album, the music player directly accesses the play address, if the account logged in the mobile phone is a bound account, a unique identifier of the album is displayed below the account, comments, pictures, the digital album and the like can be downloaded in an album interface, and if the account is a non-bound account, only the digital album can be played.

Fig. 9 is a flowchart illustrating an authority check performed by a server in a method for playing media data according to an embodiment of the present application. Referring to fig. 9, the embodiment includes:

step 901, judging whether the legal authority identifier stored in the server includes the authority identifier in the digital information.

In the implementation, the server checks the authority identifier in the list, checks whether the authority identifier in the list is the same as the authority identifier of the terminal, and if the authority identifier in the list is the same as the authority identifier of the terminal, carries out the next check.

And step 902, comparing the second count value of the terminal with the first count value of the server.

In implementation, the server queries a first count value of the server stored in the database, compares the first count value with a second count value of the terminal after the first count value is obtained, and performs the next inspection if the first count value of the server is smaller than the second count value of the terminal.

And 903, generating a digest value based on the authority identifier, the second count value and a pre-stored key in the digital information.

In implementation, the server first performs the initial digest value calculation of the server, which may be performed by using the SHA256 algorithm, first queries the list according to the authority identifier to obtain the key of the server, and then inputs the authority identifier, the second count value of the terminal, and the key of the server into the SHA256 algorithm to obtain the initial digest value of the server with 32 bits.

Secondly, the server shortens the calculated initial digest value of the server to a digest value with a uniform preset length, the step can be performed by using an MD5 message digest algorithm, and the initial digest value obtained in the step is input into an MD5 message digest algorithm, so that a digest value of the server with the preset length of 16 bits is obtained.

Step 904, determine whether the digest value of the generation server is the same as the digest value of the terminal.

In practice, the obtained digest value of the server is compared with the obtained digest value of the terminal, and if they are the same, the check is completed.

If the result of the check in any of the above steps is negative, the server sends a notification that the digital album cannot be acquired to the second terminal.

In the embodiment of the application, the digital information transmitted to the second terminal by the first terminal through the audio signal further comprises a count value which changes continuously except the authority identifier, so that the count value in the audio signal obtained through recording is the count value which is used, and when the server judges the count value, the playing address of the media data is sent to the terminal only when the count value meets the change condition, so that the media data can be prevented from being illegally played in a recording mode.
