Systems and methods for performing client-side content inference

1. A method comprising:

receiving a request to upload a content item from a client-side computing device to one or more server-side computing devices, the content item comprising at least a first sequence of bytes and a second sequence of bytes;

identifying, at the client-side computing device, at least one model configured to output one or more classifications for sequences of bytes in the content item;

using, at the client-side computing device, the at least one model to derive a first classification for the first sequence;

using, at the client-side computing device, the at least one model to derive a second classification for the second sequence; and

uploading, in response to the request, the content item from the client-side computing device to the one or more server-side computing devices by:

uploading the first sequence;

uploading the first classification substantially contemporaneous with uploading the first sequence;

uploading the second sequence; and

uploading the second classification substantially contemporaneous with uploading the second sequence.

2. The method of claim 1 , wherein the second sequence and the second classification are uploaded from the client-side computing device to the one or more server-side computing devices after the first sequence and the first classification are uploaded from the client-side computing device to the one or more server-side computing devices.

3. The method of claim 1 , wherein:

the content item comprises a video file recorded and stored at the client-side computing device;

the first sequence comprises one or more frames of the video file; and

4. The method of claim 1 , wherein:

the content item comprises a live video stream being captured by and streamed from the client-side computing device;

the first sequence comprises one or more frames of the live video stream; and

the second sequence comprises one or more additional frames of the live video stream.

5. The method of claim 1 , wherein the content item comprises at least one of:

an audio file; or

a live audio stream.

6. The method of claim 1 , wherein:

the first sequence and the second sequence are overlapping sequences;

the first classification indicates that the first sequence contains an element of a known type; and

the second classification indicates that the second sequence contains the element in an objectionable context.

8. The method of claim 1 , further comprising:

identifying, at the one or more server-side computing devices, a content policy that:

maps the first classification to a first action to be performed when any sequence of bytes has been classified with the first classification; and

uploading a first indicator of the first classification substantially contemporaneous with uploading the first byte of the first sequence; and

uploading a second indicator of the first classification substantially contemporaneous with uploading the last byte of the first sequence.

10. The method of claim 1 , wherein:

the content item further comprises a third sequence of bytes;

the method further comprises using, at the client-side computing device, the at least one model to derive a third classification for the third sequence; and

uploading the content item from the client-side computing device to the one or more server-side computing devices further comprises refraining, at the client-side computing device based at least in part on the third classification of the third sequence, from uploading the third sequence to the one or more server-side computing devices.

11. The method of claim 1 , further comprising identifying, at the client-side computing device, an upload policy that:

maps the first classification to a first action to be performed at the client-side computing device when any sequence of bytes has been classified with the first classification; and

maps the second classification to a second action to be performed at the client-side computing device when any sequence of bytes has been classified with the second classification.

12. The method of claim 11 , wherein:

the first action comprises uploading any sequence of bytes that has been classified with the first classification to a first one of the one or more server-side computing devices; and

the second action comprises uploading any sequence of bytes that has been classified with the second classification to a second one of the one or more server-side computing devices.

13. A system comprising:

one or more server-side computing devices; and

a client-side software agent, stored in physical memory of a client-side computing device and executed by a physical processor of the client-side computing device, comprising:

a receiving module that receives a request to upload a content item from the client-side computing device to the one or more server-side computing devices, the content item comprising at least a first sequence of bytes and a second sequence of bytes;

an identifying module that identifies, at the client-side computing device, at least one model configured to output one or more classifications for sequences of bytes in the content item;

a classifying module that uses, at the client-side computing device, the at least one model to:

derive a first classification for the first sequence; and

derive a second classification for the second sequence; and

an uploading module that uploads, in response to the request, the content item from the client-side computing device to the one or more server-side computing devices by:

uploading the first sequence;

uploading the first classification substantially contemporaneous with uploading the first sequence;

uploading the second sequence; and

uploading the second classification substantially contemporaneous with uploading the second sequence.

14. The system of claim 13 , wherein the uploading module uploads the second sequence and the second classification from the client-side computing device to the one or more server-side computing devices after uploading the first sequence and the first classification from the client-side computing device to the one or more server-side computing devices.

identifies, at the one or more server-side computing devices, a content policy that:

maps the first classification to a first action to be performed when any sequence of bytes has been classified with the first classification; and

maps the second classification to a second action to be performed when any sequence of bytes has been classified with the second classification;
