Electronic evidence transfer

A non-transitory computer-readable medium comprising program code which, when executed by a processing unit, causes the processing unit to perform operations for securely transferring a media file from a source computing device having a browser over a data network to a remote server, comprising:

• sending, via the browser, a request to the remote server to initiate upload of a source media file;
• obtaining, at the browser, an encryption key for use in securing the source media file;
• and
• obtaining, at the browser from the remote server, web content comprising browser instructions for:
• instantiating a first thread for managing a user interface displayed by the browser;
• instantiating at least one second thread for securing the source media file using the encryption key, thereby producing a secured media file;
• and
• uploading the secured media file to the remote server for storage.

A electronic device for handling web content in a browser, comprising:

• a processor;
• and
• a non-transitory computer readable medium storing program instructions for implementing at least a browser, the program instructions being executable by the processor for:
• connecting, via the browser, to a remote server over a data network;
• sending, via the browser, a request to initiate communication with the remote server over the data network;
• in response to the request, obtaining web content at the browser from the remote server, the web content comprising instructions for the browser for:
• instantiating a first thread for managing a user interface displayed by the browser;
• and
• instantiating a second thread for:
• managing communication with the remote server over the data network;
• and
• issuing messages to the first thread based on the communication with the remote server for causing the first thread to update the user interface displayed by the browser.
