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 in decipherable. The invention also provide method and apparatus for transmitting or streaming unredacted image cells alone or in combination with redacted image cell for secured viewing on a user browser or computer.
Claims20
A method for automatically redacting one or more digital images, the method comprising, as performed by an image security system:
- receiving a first digital image of a scanned document, the first digital image comprising a plurality of image fragments determined by dividing the first digital image according to a division pattern;
- performing a first redacting operation on a first image fragment of the plurality of image fragments, wherein the first redacting operation is of a first redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the first image fragment;
- performing a second redacting operation on a second image fragment of the plurality of image fragments, wherein the second redacting operation is of a second redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the second image fragment, and wherein the second redaction type is different from the first redaction type;
- and
- generating a second digital image of the scanned document based at least in part on outputs of the first redacting operation and the second redacting operation.
An image security system for editing one or more digital images, the image security system comprising:
- a computer processor;
- a non-transitory data store configured to store computer-executable instructions that, when executed, cause the computer processor to perform steps of:
- receiving a first digital image of a scanned document, the first digital image comprising a plurality of image fragments determined by dividing the first digital image according to a division pattern;
- performing a first redacting operation on a first image fragment of the plurality of image fragments, wherein the first redacting operation is of a first redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the first image fragment;
- performing a second redacting operation on a second image fragment of the plurality of image fragments, wherein the second redacting operation is of a second redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the second image fragment, and wherein the second redaction type is different from the first redaction type;
- and
- generating a second digital image of the scanned document based at least in part on outputs of the first redacting operation and the second redacting operation.
A non-transitory computer storage having stored thereon a computer program, the computer program including executable instructions that instruct an image security system to at least:
- receive a first digital image of a scanned document, the first digital image comprising a plurality of image fragments determined by dividing the first digital image according to a division pattern;
- performing a first redacting operation on a first image fragment of the plurality of image fragments, wherein the first redacting operation is of a first redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the first image fragment;
- performing a second redacting operation on a second image fragment of the plurality of image fragments, wherein the second redacting operation is of a second redaction type comprising at least one of:
- blurring, masking, or inserting a line over all or just a portion of the second image fragment, and wherein the second redaction type is different from the first redaction type;
- and
- generate generating a second digital image of the scanned document based at least in part on outputs of the first redacting operation and the second redacting operation.
