Security system and method of in-flight entertainment device rentals having self-contained, audiovisual presentations
A security method for in-flight entertainment device (IFED) rentals having self-contained, audiovisual presentations is disclosed. A self-contained IFED has internal storage configured to contain current releases of movies and other audiovisual presentations. The method provides layers of security including unique bit stream encoding format, watermarking, camera artifacts, file encryption, hard drive encryption, input-output encryption and physically unique connectors, and tamper resistant casing the self-contained IFEDs.
1. A portable, self-contained entertainment device, comprising:
one or more processors;
a hard drive configured to store a plurality of encrypted audiovisual presentations corresponding to to-be-released or current releases of movies, each audiovisual presentation of the plurality of audiovisual presentations being derived from one or more master files provided by a movie studio or a movie distributor for inclusion on portable, self-contained entertainment devices;
a visual display;
an audio output;
an input-output configured to connect the portable, self-contained entertainment device to a distribution device, the distribution device configured to transfer to the hard drive one or more encrypted audiovisual presentations and keys associated with the encrypted audiovisual presentations without decryption of the encrypted audiovisual presentations being transferred to the hard drive and to delete from the hard drive one or more previously stored encrypted audiovisual presentations, wherein the one or more encrypted audiovisual presentations is encoded and includes a watermark identifying a time and place at which the audiovisual presentation was encoded;
an input-output authenticator configured to authenticate the distribution device the distribution device further configured to communicatively link to the one or more processors via the input-output, the input-output authenticator configured to limit communication between the distribution device and the hard drive before authentication; and
a file decryptor configured to decrypt the plurality of encrypted audiovisual presentations using the one or more keys obtained from the distribution device.
2. The portable, self-contained entertainment device recited in claim 1 , wherein the input-output authenticator requires authentication within a limited time window.
3. The portable, self-contained entertainment device recited in claim 2 , wherein the input-output authenticator requires a physical disconnection and reconnection to restart authentication if authentication is not completed within the limited time window.
4. The portable, self-contained entertainment device recited in claim 1 , wherein the input-output includes a physical connection configured as an exclusive input for content to the portable, self-contained entertainment device.
