System and media recording device with secured encryption

A body-worn device for providing media content to a media server, comprising:

• a hardware recording unit producing unencrypted media content;
• an interface module for:
• obtaining, from the media server, a request to access the media content produced by the body-worn device;
• sharing, with the media server, a first encryption key for use in generating encrypted media content from the unencrypted media content produced by the body-worn device;
• and
• transmitting the encrypted media content to the media server;
• and
• a cryptography engine for, prior to said transmitting the encrypted media content to the media server:
• generating the encrypted media content by encrypting the unencrypted media content using the first encryption key;
• performing a cryptographic operation to secure the first encryption key using a first asymmetric encryption key;
• and
• the body-worn device preventing external access to the unencrypted media and to the first encryption key.

A method for providing media content to a media server, comprising:

• recording, at a hardware recording unit of a body-worn device, unencrypted media content;
• obtaining, from the media server, a request to access the media content produced by the body-worn device;
• prior to transmitting the media content to the media server:
• sharing, via an interface module of the body worn device, a first encryption key for use in generating encrypted media content from the unencrypted media content produced by the body-worn device;
• generating, at a cryptography engine of the body-worn device, the encrypted media content by encrypting the unencrypted media content using the first encryption key;
• performing, at the cryptography engine of the body-worn device, a cryptographic operation to secure the first encryption key using a first asymmetric encryption key;
• and
• transmitting, via the interface module, the encrypted media content to the media server;
• and
• preventing external access to the unencrypted media and to the first encryption key.
