Word tone is happy, and provides the original copyright description information of the original figure music；In May, 2015, company A will number original for M15
The copyright transfer of beginning digital music is to music platform B for providing a user the business such as broadcasting, downloading；2016, music platform B
Give company C, the company C of allowing the original figure music can be used for quotient the copyright transfer for numbering original figure music for M15
Industry is performed or is turned over and sings；Finally, 2017, the copyright transfer of the original figure music is given company D, the company D of allowing that can answer by company C
Make the original figure music.
Original copyright information due to directly recording original figure music be easy to cause the loss of original copyright information, and
Be easily modified, encrypted so the generation of above situation in order to prevent, in the embodiment of the present application one using block chain book keeping operation mode and
Record the original copyright information.When encrypting and recording the original copyright information using block chain book keeping operation mode, it is necessary first to create
First block is built, first block is divided into two parts: block head records the information of current block；Block body records actual number
According to.What the block head in first block recorded is the original copyright description information for describing copyright itself, is recorded in block body
It is the detail information of copyright itself, such as the publication time of original figure music, publishing company, songwriter, composer etc..Then,
According to the information in the first block, in conjunction with subsidiary company A to music platform B for indicating the original version of copyright transfer relevant information
It weighs transferable information and creates the second block, second block is divided into two parts: block head records the information of current block；Block body,
Record real data.The original copyright description information and original copyright of record description copyright itself in block head in second block
Transferable information records the detail information of copyright itself in block body, and such as the publication time of original figure music, publishing company makees
Word person, the equal transfer routing information with subsidiary company A to music platform B of composer.Then according to the first block and the second block
Information generates third block information in conjunction with new transfer routing information, and so on, until original copyright information record finishes.
It is new due to that can only be combined according to the information of previous block when encrypting and record the original copyright information using block chain book keeping operation mode
Information generate the information of latter block, include not only new transferable information in the latter block formed in this way, further include previous
All information of block, i.e., original version can clearly be recorded by encrypting and record the original copyright information using block chain book keeping operation mode
Weigh description information and entire transfer history and approach record.
It should be noted that the original copyright information is for identifying the original copyright description information and described original
Original copyright description information digest algorithm in first block is generated corresponding pluck by the summary info of copyright transfer information
Information is wanted, the algorithm used in the embodiment of the present application is for Sha256 algorithm, by data (all information in such as block 1) operation
Another fixed-length value (summary info).The information in block one is referred to as information A1 in the embodiment of the present application one, by block
Information in two includes that block one and the transferable information including subsidiary company A to platform B are known as information AB1, will be in block three
Information is known as information ABC1, and the information in block four is known as information ABCD1, then, by information A1, AB1, ABC1, ABCD1 according to
It is secondary that summary info is generated using Sha256 algorithm, it is denoted as summary info A2, AB2, ABC2, ABCD2 respectively.It will be each with digest algorithm
Information in block generates corresponding summary info, and summary info is unique, and irreversible, so, copyright transfer information is being transferred the possession of
History in the process can be now uniquely determined, and can not be changed.
The embodiment of the present application is using SHA256 digest algorithm, in other embodiments, can also be using other calculations
Original copyright information is generated summary info by method, and the Message Digest 5 further includes MD5, SHA1 scheduling algorithm.
After obtaining to original copyright information used in raw digital audio progress copyright protection, need to the original
Beginning copyright information is further processed, and concrete processing procedure is shown in step S103.
Original copyright information is generated as copyright digital sound by step S103.
In this step, need, according to the corresponding summary info generated of original copyright information, version will to be converted into step S102
Weigh digital audio.Specifically, converting audio signal for summary info.
When converting audio signal for summary info, there are three types of transform modes, the first is to convert original copyright information
For infrasonic sound filtered audio signal；Second is to convert ultrasonic audio signal for original copyright information；The third is by original version
Power information is converted into infrasonic sound filtered audio signal and ultrasonic audio signal simultaneously.
Before converting audio signal for original copyright information, which can be split as the first original version
Sub-information and the second original copyright sub-information are weighed, such as: using the information in block one or block two as the first original copyright
Information, and infrasonic sound filtered audio signal is converted by the summary info generated by the information in block one or block two, by block three
Or in block four information the original copyright sub-information of conduct second, and will by block three or block four information generate abstract
Information is converted into ultrasonic acoustic filtered audio signal.
Step S104 mixes raw digital audio and copyright digital sound, and generation obtains the number of copyright protection
Sound.
Raw digital audio and copyright digital sound are mixed, i.e., generated the original figure music in step S101
Audio signal and step S103 in original copyright information copyright digital sound generate infrasonic sound filtered audio signal and/or ultrasound
Filtered audio signal carries out mixing and generates mixed audio signal.
The process of mixed audio signal is generated as shown in figure 3, it illustrates a kind of different frequencies provided by the embodiments of the present application
The sound wave of rate is superimposed flow chart.As seen from Figure 3, sound wave 1 and copyright digital in audio signal original figure music generated
The sound wave in 2 audio signal of infrasonic sound filtered audio signal and/or ultrasonic wave that sound generates carries out the superposition of different frequency wave, generates
The sound wave 3 of hybrid digital sound.
After the sound wave in above two audio signal to be overlapped to generation mixed audio signal, then to the mixed audio
Signal is digitized, and obtains the digital audio of copyright protection to generate.Because of raw digital audio and copyright digital sound
Audio signal be all analog audio signal, to superposition audio signal digitizing exactly convert number for superposed simulation audio signal
Word audio signal, analog audio signal are one in time with signal all continuous in amplitude, its digitized process is as follows
It is described:
The process that analog signal is converted into digital signal is called analog/digital conversion, this process needs use ADC modulus
Converter, analog audio signal digitlization one is divided into three steps: the first step is sampling: i.e. on a timeline to signal number
Word.It is, the value of analog signal is extracted according to fixed time interval, in this way, after sampling just a time can connect
Continuous intelligence wave becomes the discrete signal of value Limited Number in time.It is Shannon to the digitized foundation of analog audio signal
Sampling thheorem, the 1940s, Shannon demonstrated sampling thheorem, i.e., under certain condition, can complete generation with discrete sequence
One continuous function of table, but also required in aromatic sampling thheorem in order to guarantee that the digital signal after digitlization can completely include
The originally information in analog signal, in order to guarantee that digital signal is undistorted, sample frequency is had to be larger than by sampled signal bandwidth
Twice.It, otherwise cannot be from adopting in order to avoid aliasing sample rate has to be larger than 200Hz if the bandwidth of signal is 100Hz
Restore original signal in sample signal.If sample frequency is significantly larger than 2 times of signal bandwidths, aliasing can be helped to avoid, improves and divides
Resolution and reduction noise.
Uniform sampling is used in the embodiment of the present application one when sampling to hybrid analog-digital simulation audio signal, i.e., every equal
A bit of time sampling it is primary, at this point, sampling period T: press certain time interval (T) value, 1/T is known as sample frequency,
Need to acquire how many a sample sounds each second (sample frequency fs, unit are samples/sec, i.e. hertz Hz).Wherein, sampling frequency
