Abstract

The invention provides methods and apparatus for securing personalized or sensitive information appearing in digital images. Digital images containing information to be secured is processed and divided into a plurality of image cells. At least one image cell from the plurality of image cells is selected and redacted or altered to render the information to be secured with the selected image cells indecipherable. The invention also provides methods and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cells for secured viewing on a user browser or computer.

Claims

1. A method for securely transmitting a digital image containing sensitive information, the method comprising:

selecting a digital image with sensitive information for processing by an image security system;

dividing the selected digital image into a plurality of image cells according to a predetermined cell division pattern that is selected based on a type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

assigning each of the plurality of image cells with a cell identifier;

automatically selecting from the plurality of image cells at least one image cell for redaction based on its position within the predetermined cell division pattern and the type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

instructing the image security system to automatically redact the selected position-based at least one image cell from the plurality of image cells, thereby generating a redacted digital image without generating an unredacted version;

transmitting the redacted digital image, wherein no images are generated which reveal redacted information; and

generating a new digital image for display on a device following the transmitting step which is missing the redacted information.

2. The method of claim 1, wherein more than one digital image can be selected and redacted at the same time in a high throughput automated process.

3. The method of claim 1, wherein dividing the selected digital image into a plurality of image cells can be performed by dividing the selected digital image into a grid of image cells comprising at least one row and at least one column.

4. A non-transitory computer readable medium containing program instructions for automatically securing a digital image which contains sensitive information, comprising:

program instructions for selecting a digital image with sensitive information to be securely shown as a displayed image on a display for processing by an image security system;

program instructions for dividing the selected digital image into a plurality of image cells according to a predetermined cell division pattern that is selected based on a type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

program instructions for assigning each of the plurality of image cells with a cell identifier;

program instructions for automatically selecting from the plurality of image cells a set of image cells for redaction based on its position within the predetermined cell division pattern and the type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

program instructions for instructing the image security system to automatically redact the selected set of positioned-based image cells from the plurality of image cells, thereby generating a redacted digital image for secure viewing of the redacted digital image;

program instructions for transmitting the redacted digital image, thereby rendering only the redacted digital image for display; and

program instructions for generating a new digital image for display on a device following the transmitting step which is missing the redacted information.

5. The non-transitory computer readable medium of claim 4, wherein the computer readable medium selects and transmits more than one digital image at the same time.

6. The non-transitory computer readable medium of claim 4, wherein the computer readable medium divides the selected digital image into a plurality of image cells based on one of a plurality of division patterns, the division patterns including:

dividing the selected digital image into a grid of image cells comprising at least one row and at least one column.

7. A method for securely transmitting a digital image containing sensitive information, the method comprising:

selecting a digital image with sensitive information for processing by an image security system;

dividing the selected digital image into a plurality of image cells according to a predetermined cell division pattern that is selected based on a type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

assigning each of the plurality of image cells with a cell identifier;

automatically selecting from the plurality of image cells at least one image cell for redaction based on its position within the predetermined cell division pattern and the type of document selected from at least one of the following;

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, and a medical record;

instructing the image security system to automatically and permanently redact the selected at least one position-based image cell from the plurality of image cells to form an unredactable displayed digital image;

transmitting a complete set of image data corresponding to the digital image, thereby permanently redacting the sensitive information; and

generating a new digital image for display on a device following the transmitting step which is missing the redacted information.
