In general; the contemplated above technical scheme of the present invention is compared with prior art; by utilizing buffer queue by duration predetermined for video cache; the operating time has been supplied for the user discover that and deleting sensitive video frequency content; there is feasibility; when uninterruptedly live, protection private data does not leak in time, it is ensured that the health of content.
Accompanying drawing explanation
Accompanying drawing 1 is the flow chart during normal play of the present invention.
Accompanying drawing 2 is the privacy process chart of the present invention.
Accompanying drawing 3 is the structure chart of the present invention.
Detailed description of the invention
By the examples below, and in conjunction with accompanying drawing, technical scheme is described in further detail.
A kind of for live method for secret protection, including:
Step 1, provides a user with a configuration interface, receives the cache-time pre-set described in user's input in described configuration interface.Set up and maintain a buffer queue, the audio, video data after coding is put in buffer queue.
Step 2, it is judged that whether the audio, video data in buffer queue reaches the cache-time pre-set, if reaching, then the audio, video data of cache-time being up to pre-set pushes to server；If all audio, video datas in buffer queue all not up to the cache-time pre-set, then obtain the acquiescence audio, video data pre-set and push to server.The cache-time pre-set is 1 minute.
Step 3, it is judged that whether user submits erasing request of data to, if judging, user have submitted erasing request of data, then removed by the audio, video data in buffer queue.
A kind of for live privacy protection device, including:
Cache module, provides a user with a configuration interface, receives the cache-time pre-set described in user's input in described configuration interface；Set up and maintain a buffer queue, the audio, video data after coding is put in buffer queue；
Pushing module, it is judged that whether the audio, video data in buffer queue reaches the cache-time pre-set, if reaching, then the audio, video data of cache-time being up to pre-set pushes to server；If all audio, video datas in buffer queue all not up to the cache-time pre-set, then obtain the acquiescence audio, video data pre-set and push to server.The cache-time pre-set is 1 minute.
Erasing module, it is judged that whether user submits erasing request of data to, and user have submitted erasing request of data if judging, then remove the audio, video data in buffer queue.
Embodiment 1:
First, the term of the present embodiment is described as follows:
Cache-time: the cache-time of user setup, is typically in about 1 minute；
Domestic consumer: log in the user of APP；
Server: refer generally to background service；
Aac encodes: Advanced Audio Coding, comes across 1997, based on the audio decoding techniques of MPEG-2；
H.264: set up on the basis of MPEG-4 technology, its encoding and decoding flow process mainly includes 5 parts: interframe and infra-frame prediction (Estimation), conversion (Transform) and inverse transformation, quantization (Quantization) and inverse quantization, loop filtering (LoopFilter), entropy code (EntropyCoding).
Shown in Fig. 1, the normal play flow process of the present embodiment is described as follows:
Step 1: user setup postpones duration.User setup postpone live duration, the time that generally arranges at about 1 minute, too short be not enough to protection privacy, oversize affect user viewing
Step 2: user starts live.
User starts live, starts audio frequency and video sampling and coding.Video is sampled by photographic head, adopts h246 coding.Audio frequency gathers sound by mike, adopts aac coding.
Step 3: audio, video data after transmission coding.Step 3, by the data after being encoded by step 2, is delivered to bottom.
Step 4: add buffer queue.Audio, video data after coding is added buffer queue.
Step 5: judge whether to arrive the duration of user setup.Judge whether the audio, video data of buffer memory arrives the delay duration of user setup.If result whether, then obtain acquiescence audio, video data, such as user waiting prompt.If arriving, then take out data bottom buffer memory
Step 6: propelling data.Push the data transmitted by step 5 to server.
Shown in Fig. 2, the secret protection flow process of the present embodiment is described as follows:
Step 1: user clicks erasing data.When user photographs privacy content time, click erasing data immediately.
Step 2: empty buffer queue.Deposit long data during the delay of user setup in buffer queue, now empty buffer queue data and be possible to prevent private data to upload onto the server.
Step 3: add buffer queue.Audio, video data after coding is added buffer queue.
Step 4: judge whether to arrive the duration of user setup.Judge whether the audio, video data of buffer memory arrives the delay duration of user setup.If not: obtain default image data, such as user waiting prompt.If arriving: take out data bottom buffer memory
Step 5: propelling data.Push the data transmitted by step 4 to server.
Embodiment 2:
The present invention also provides for a kind of for live privacy protection device, including:
Cache module, provides a user with a configuration interface, receives the cache-time pre-set described in user's input in described configuration interface；Set up and maintain a buffer queue, the audio, video data after coding is put in buffer queue；
Pushing module, it is judged that whether the audio, video data in buffer queue reaches the cache-time pre-set, if reaching, then the audio, video data of cache-time being up to pre-set pushes to server；If all audio, video datas in buffer queue all not up to the cache-time pre-set, then obtain the acquiescence audio, video data pre-set and push to server.The cache-time pre-set is 1 minute.
Erasing module, it is judged that whether user submits erasing request of data to, and user have submitted erasing request of data if judging, then remove the audio, video data in buffer queue.
Specific embodiment described herein is only to present invention spirit explanation for example.Described specific embodiment can be made various amendment or supplements or adopt similar mode to substitute by those skilled in the art, but without departing from the spirit of the present invention or surmount the scope that appended claims is defined.
