Abstract

Claims (52)

1. A system for image encryption, comprising:

a computing device in communication with the image recording device, wherein the computing device is configured to:

receive image data from an image recording device;

detect a human face in the image data as a function of a facial recognition process;

modify the image data to produce modified image data, wherein to modify the image data the computing device is further configured to:

generate a face crop image comprising substantially only the human face;

encrypt the face crop image using an encryption process, wherein keys of the encryption process include a first encryption key unique to the image recording device and a second encryption key unique to the face crop;

reversibly obscure only the face crop image separate from a background of the image data resulting in the modified image data comprising the obscured face crop image and unobscured background;

embed the encrypted data of the face crop image of the modified image data in meta data of the image data; and

communicate the modified image data to a remote computing device, wherein the modified image data is reversible to an original image of the image data upon decryption of the second encryption key.

2. The system of claim 1 , wherein the computing device is further configured to:

receive a decryption key from the other computing device; and

reverse an obscurement of the face crop image.

3. The system of claim 2 , wherein the computing device is further configured to generate an audit record of the reversing of the obscurement of the face crop image.

4. The system of claim 1 , wherein the computing device is further configured to communicate keys of the encryption process with a key escrow.

5. The system of claim 1 , wherein the computing device is further configured to initialize an image recording device in communication with the computing device through a camera provisioning process.

6. The system of claim 1 , wherein the computing device is further configured to perform a monitoring process, wherein to perform the monitoring process the computing device is further configured to:

receive a redacted image from a device; and

communicate the redacted image to a user.

7. The system of claim 1 , wherein the image recording device is one of a mobile computing device, a residential security camera, or a commercial security camera.

8. A method for image encryption, comprising:

receiving image data at a computing device from an image recording device;

detecting a human face in the image data, at the computing device, as a function of a facial recognition process;

modifying the image data, at the computing device, wherein modifying the image data comprises:

generating a face crop image comprising substantially only the human face;

encrypting the face crop image using an encryption process, wherein keys of the encryption process include a first encryption key unique to the image recording device and a second encryption key unique to the face crop;

reversibly obscuring only the face crop image from a background of the image data resulting in the modified image data comprising the obscured face crop image and unobscured background;

embedding the encrypted data of the face crop image of the modified image data in meta data of the image data; and

communicating the modified image data to a remote computing device, wherein the modified image data is reversible to an original image of the image data upon decryption of the second encryption key.

9. The method of claim 8 , further comprising:

receiving, at the computing device, decryption keys; and

reversing an obscurement of the face crop image.

10. The method of claim 9 , further comprising:

generating, at the computing device, an audit record of the reversing of the obscurement of the face crop image.

11. The method of claim 8 , further comprising communicating with a key escrow to receive decryption keys specific to the face crop image.

12. The method of claim 8 , wherein reversibly obscuring the face crop image includes pixelating the face crop image.

13. The method of claim 8 , further comprising downsampling, by the facial recognition process, the image data into a value map.

14. The method of claim 8 , further comprising initializing the image recording device through a camera provisioning process.

15. The method of claim 8 , further comprising associating, by the image facial recognition process, an identity of an individual with the image data.

16. A system for image encryption, comprising:

a computing device in communication with the image recording device, wherein the computing device is configured to:

receive image data from an image recording device;

detect a human face in the image data as a function of a facial recognition process;

modify the image data to produce modified image data, wherein to modify the image data the computing device is further configured to:

generate a face crop image comprising substantially only the human face;

encrypt the face crop image using an encryption process, wherein keys of the encryption process include a first encryption key unique to the image recording device and a second encryption key unique to the face crop; and

reversibly obscure only the face crop image separate from a background of the image data resulting in the modified image comprising the obscured face crop image and unobscured background;

embed the encrypted data of the face crop image of the modified image data in meta data of the image data;

communicate the modified image data to a remote computing device, wherein the face crop of the modified image data is reversible to an original image upon decryption of the second encryption key; and

perform an interrogation process, wherein to perform the interrogation process the computing device is further configured to:

receive a request for an unredacted image for a specific time period from a user; and

communicate with a key escrow to provide the user with the first and second encryption keys to access the unredacted image for a specific time period, wherein the key escrow stores an audit record of the request of the user.
