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 automatically redacting a digital image, the method comprising:

accessing a digital image for processing by an image security system, the digital image including sensitive information and associated with a predetermined document type of a plurality of predetermined document types;

accessing a cell division pattern associated with the predetermined document type;

dividing the digital image into a plurality of image cells according to the predetermined cell division pattern;

and

determining at least one image cell of the plurality of image cells that includes the sensitive information;

determining within the at least one image cell, a first portion of the at least one image cell that includes the sensitive information and a second portion of the at least one image cell that does not include the sensitive information; and

editing the digital image to redact the first portion of the at least one image cell and leaving the second portion of the at least one image cell unredacted.

2. The method of claim 1, wherein the plurality of predetermined document types comprises at least one of:

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, a medical record, or a variation in font or layout of a document type in the plurality predetermined document types.

3. The method of claim 1, wherein editing digital image comprises at least one of:

masking in solid color, pixelating, encrypting, or otherwise rendering the first portion of the at least one image cell indecipherable.

4. The method of claim 1, wherein the cell division pattern comprises a grid of image cells of the plurality of image cells, wherein the grid comprises at least one row and at least one column.

5. An image security system for redacting a digital image, the image security system comprising:

a non-transitory data store configured to store a plurality of digital images and cell division patterns associated with a plurality of predetermined document type;

a computer processor programmed to;

access, from the non-transitory data store, a digital image of the plurality of digital images, the digital image including sensitive information and associated with a predetermined document type of the plurality of predetermined document types;

access, from the non-transitory data store, a cell division pattern of the plurality of cell division patterns associated with the predetermined document type;

divide the digital image into a plurality of image cells according to the predetermined cell division pattern;

determine at least one image cell of the plurality of image cells that includes the sensitive information;

determine within the at least one image cell, a first portion of the at least one image cell that includes the sensitive information and a second portion of the at least one image cell that does not include the sensitive information; and

edit the digital image to redact the first portion of the at least one image cell and leaving the second portion of the at least one image cell unredacted.

6. The image security system of claim 5, wherein the plurality of predetermined document types comprises at least one of:

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, a medical record, or a variation in font or layout of a document type in the plurality predetermined document types.

7. The image security system of claim 5, wherein to edit the digital image, the computer processor is programmed to perform at least one of:

masking in solid color, pixelating, encrypting, or otherwise rendering the first portion of the at least one image cell indecipherable.

8. The image security system of claim 5, wherein the cell division pattern comprises a grid of image cells of the plurality of image cells, wherein the grid comprises at least one row and at least one column.

9. A non-transitory computer readable medium containing program instructions for automatically redacting a digital image which contains sensitive information, wherein the program instructions causing an image security system to:

access a digital image for processing by an image security system, the digital image including sensitive information and associated with a predetermined document type of a plurality of predetermined document types;

access a cell division pattern associated with the predetermined document type;

divide the digital image into a plurality of image cells according to the predetermined cell division pattern;

determine at least one image cell of the plurality of image cells that includes the sensitive information;

determine within the at least one image cell, a first portion of the at least one image cell that includes the sensitive information and a second portion of the at least one image cell that does not include the sensitive information; and

edit the digital image to redact the first portion of the at least one image cell and leaving the second portion of the at least one image cell unredacted.

10. The non-transitory computer readable medium of claim 9, wherein the plurality of predetermined document types comprises at least one of:

a check, a deposit slip, a bank statement, a credit card bill, a tax return, a driver'"'"'s license, a medical record, or a variation in font or layout of a document type in the plurality predetermined document types.

11. The non-transitory computer readable medium of claim 9, wherein to edit the digital image, the program instructions causes the image security system to perform at least one of:

masking in solid color, pixelating, encrypting, or otherwise rendering the first portion of the at least one image cell indecipherable.

12. The non-transitory computer readable medium of claim 9, wherein the cell division pattern comprises a grid of, image cells of the plurality of image cells, wherein the grid comprises at least one row and at least one column.
