Abstract

A computer system receives event data associated with data records in a database, receives metadata corresponding to a digital media content file (e.g., a video, audio, or image file), compares the event data with the metadata, automatically identifies a matching event based on the comparison, and automatically tags the content file by modifying the metadata based on event data associated with the matching event. In one usage scenario, the digital media content file may be used as evidence in a criminal investigation. The event data may be provided in the form of a summary or snapshot of the database, which may include data records covering a limited period of time. The digital media content file can be recorded by any suitable digital media device, such as a video camera. The computer system may further include a dock configured to upload digital media content received from the digital media device.

Claims

1. A computer-implemented method comprising:

receiving event data associated with a plurality of data records in a database;

receiving metadata corresponding to a digital media content file;

performing a comparison of at least a portion of the event data with at least a portion of the metadata;

based on the comparison, automatically identifying a matching event for the digital media content file, wherein the matching event is associated with at least one of the data records; and

automatically modifying the metadata based on event data associated with the matching event.

2. The method of claim 1, wherein the comparison comprises:

comparing a user identifier in the metadata with a user identifier in the event data; and

comparing a time frame in the event data with a time frame in the metadata.

3. The method of claim 1, wherein the comparison comprises at least one of the following:

comparing a user identifier in the metadata with a user identifier in the event data;

comparing a time frame in the event data with a time frame in the metadata; and

comparing a location in the event data with a location in the metadata.

4. The method of claim 1, wherein automatically modifying the metadata comprises adding to the metadata at least one of the following:

an event identifier, an event type, and a location.

5. The method of claim 1, wherein the database comprises a records management system database or a computer-aided dispatch database.

6. The method of claim 1, wherein the digital media content file comprises a video file.

7. The method of claim 1, wherein the digital media content file comprises an audio file.

8. The method of claim 1, wherein the digital media content file comprises an image file.

9. The method of claim 1, wherein the metadata is included in the digital media content file.

10. The method of claim 1, wherein the event data is included in a database snapshot.

11. The method of claim 10, wherein the database snapshot is generated periodically at a regular time interval.

12. The method of claim 11, wherein the database snapshot includes data in a look-back window that exceeds the regular time interval.

13. The method of claim 1, further comprising analyzing the modified metadata in response to a search query.

14. The method of claim 13, wherein the search query comprises a search parameter, and wherein the modified metadata includes metadata corresponding to the search parameter.

15. The method of claim 14, further comprising providing a search result based on the analysis of the modified metadata.

16. A computer-implemented method comprising:

detecting event data in a destination folder, wherein the event data is associated with a plurality of data records in a database;

in response to the detecting, uploading the event data to a service provider computer system;

by the service provider computer system, receiving metadata corresponding to a digital media content file;

by the service provider computer system, performing a comparison of at least a portion of the event data with at least a portion of the metadata;

by the service provider computer system, automatically identifying a matching event for the digital media content file based on the comparison, wherein the matching event is associated with at least one of the data records; and

by the service provider computer system, automatically modifying the metadata based on event data associated with the matching event.

17. The method of claim 16, wherein the event data is included in a database snapshot.

18. The method of claim 17, wherein the database snapshot is generated periodically at a regular time interval.

19. The method of claim 16, further comprising encrypting the event data prior to uploading the event data.

20. The method of claim 19, further comprising, by the service provider computer system, decrypting the event data prior to performing the comparison.

21. A system comprising a service provider computing device having one or more processors and computer-readable storage media having stored thereon computer-executable instructions configured to cause the service provider computing device to:

receive event data associated with a plurality of data records in a database;

receive metadata corresponding to a digital media content file;

perform a comparison of at least a portion of the event data with at least a portion of the metadata;

based on the comparison, automatically identify a matching event for the digital media content file, wherein the matching event is associated with at least one of the data records; and

automatically modify the metadata based on event data associated with the matching event.

22. The computer system of claim 21 further comprising a dock configured to upload the digital media content file to the service provider computing device.

23. The computer system of claim 21 further comprising a server computer configured to:

detect the event data in a destination folder;

encrypt the event data; and

upload the encrypted event data to the service provider computing device.
