Below in conjunction with the accompanying drawings, it elaborates to some embodiments of the present invention.In the absence of conflict, following
Feature in embodiment and embodiment can be combined with each other.
First embodiment
Referring to Fig. 1, being the flow chart of broadcasting and TV cloud platform video stream processing method provided in an embodiment of the present invention.Below will
Detailed process shown in FIG. 1 is described in detail.
Pending video stream data is divided into multiple data blocks by step S101.
Wherein, the pending video stream data distributed storage is in cloud HDFS.
As an implementation, the pending video stream data is divided into multiple data blocks according to default size,
The number of the multiple data block is denoted as N.For example, the size of the pending video stream data D is size, and according to mKB
It is split, then block count N=|size/m|。
Optionally, it is d to enable the data block after segmentation1,d2,...,dn, and remember di(di∈ D) sequence of positions in original
Number is denoted as oi。
Optionally, before step S101, further include：
Original video flow data is compressed, using compressed video stream data as pending video stream data.
Step S102 chooses the multiple data partial data block in the block as be-encrypted data according to preset rules
Block.
Wherein, the quantity of the partial data block is less than the quantity corresponding to the multiple data block.
Continue for by taking previous example as an example, such as the quantity of partial data block is k, then the k is less than piecemeal sum N.
As an implementation, the multiple data partial data block in the block is randomly selected as be-encrypted data
Block.Such as, the random number for generating encrypted data block, the number are denoted as k, and the k is greater than or equal to zero, and less than described
The summation N of multiple data blocks；The one-dimension array A for regenerating the k element, enables A={ a1,a2,...,ak, wherein aiIt takes
The random integers of [0, N] indicate that the sequence of positions by encrypted data block in the pending video flowing is numbered；It is then described
K number is the be-encrypted data block according to block.
Each be-encrypted data block is encrypted in step S103.
As an implementation, sequence of positions of each data block in the pending video stream data is obtained to compile
Number；Each be-encrypted data block is encrypted based on classical Rinjdael algorithms, generates the first ciphertext；To the multiple
Data block carries out MD5 operations respectively, generates the globally unique identifier of each data block；Based on sequence of positions number, institute
State the serial number gencration reconstruct file of globally unique identifier and the be-encrypted data block；Based on the classics Rinjdael algorithms
The reconstruct file is encrypted, the second ciphertext is generated.
Continue for by taking previous example as an example, specifically, first obtains each data block in the pending video stream data
Middle sequence of positions number oi, it is then based on classical Rinjdael algorithms and generates the key K that length is 128；Pass through the key K
The K be-encrypted data blocks are encrypted respectively, generate the K the first ciphertextsWherein, described
Indicate a in the one-dimension array AiIt is encrypted.Then D ← (D A) ∪ A ' are enabled again, and the A ' expressions are to the number in the A
According to the data after being encrypted, the D A indicate unencryption data block, then in the D arbitrary data block carry out MD5
Operation generates MD5 (di), by MD5 (di) it is used as diTitle and globally unique identifier gi, wherein the diIt indicates in the D
I-th of data block.Then again by oi、giCorrespondence stored with the credible trees of Merkle, while with the be-encrypted data block
Serial number generate reconstruct file f together, and the f is encrypted using classics Rinjdael algorithms, the second ciphertext E of generationK(f)。
Wherein, the oi、giCorrespondence refer to the oiThat indicate is the sequence of i-th of data block, the giIt indicates
Be globally unique identifier of i-th of data block after MD5 operations.
The data block of unencryption in encrypted data block and the multiple data block is carried out distributed cloud by step S104
End storage, wherein the storage order of the encrypted data block and the data block of the unencryption in the pending video
Sequence of positions in stream is different.
Wherein, the storage order refers to the sequence of all data block in storage in deposit cloud HDFS, and not with institute
The sequence of positions stated in pending video flowing is identical.The sequence of positions refer to each data block at the beginning, come pending
Priority position relationship in video flowing.
As an implementation, to sequence of positions number, the globally unique identifier and the multiple number
Upset according to block, records the target designation for the data block being disturbed；Described first corresponding to encrypted data block is close
In literary and described second ciphertext and the multiple data block corresponding to the data block of unencryption the sequence of positions number and
The target designation is stored.
Can also be before encryption to multiple numbers wherein it is possible to be to carry out upsetting storage after encryption to each data block
Upset according to block, then data block to be encrypted is being chosen, in short, those skilled in the art can select according to demand
It takes, here, being not especially limited.
For example, first generating the random number i between 1-N, completed to o using random scrambling linear congruential methodi、giAnd video flowing
Data block diFalse links, the number of genesis sequence garbled data block, that is, the target designation X for the data block being disturbedi.Then
By the ciphertext E of fK(f)、Xi、And D A be uploaded to broadcast television cloud center and stored, with ensure data safety and
Reliability.
Broadcasting and TV cloud platform video stream processing method provided in this embodiment is more by the way that pending video stream data to be divided into
A data block；The multiple data partial data block in the block is chosen as be-encrypted data block according to preset rules；To each
The be-encrypted data block is encrypted；The data block of unencryption in encrypted data block and the multiple data block is carried out
Distributed high in the clouds storage, wherein the storage order of the encrypted data block and the data block of the unencryption is waited for described
The sequence of positions handled in video flowing is different, in the environment of network opening so that criminal is although institute can be read
There is the massive video flow data block being stored on Cloud Server, but which data block belongs to same file and by what kind of on earth
Sequence composition this document, illegal invasion person are unable to find out, and the new media news video for thereby reducing broadcasting and TV cloud platform is illegal
The risk that person distorts.
