Methods and apparatus for securely displaying digital images

A method for temporarily redacting a digital image, the method comprising:

• receiving a digital image of a scanned document;
• accessing, from one or more data stores, a division pattern associated with a document type of the document;
• dividing the digital image into a plurality of image fragments according to the division pattern;
• selecting a first image fragment from the plurality of image fragments, wherein the first image fragment is selected based at least in part on a location of the first image fragment within the digital image;
• generating a redacted document by performing a first redacting operation on the first image fragment, wherein the first redacting operation comprises at least one of:
• encrypting, blurring, masking, or inserting a line over all or just a portion of the first image fragment;
• transmitting, to a remote server, the redacted document;
• receiving, from the remote server, the redacted document;
• and
• generating an unredacted document by performing a first unredacting operation on the first image fragment, wherein the first undredacting operation is based at least partially on the first redacting operation.

An image security system for editing a digital image, 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 digital image of a scanned document;
• accessing, from one or more data stores, a division pattern associated with a document type of the document;
• dividing the digital image into a plurality of image fragments according to the division pattern;
• selecting a first image fragment from the plurality of image fragments, wherein the first image fragment is selected based at least in part on a location of the first image fragment within the digital image;
• generating a redacted document by performing a first redacting operation on the first image fragment, wherein the first redacting operation comprises at least one of:
• encrypting, blurring, masking, or inserting a line over all or just a portion of the first image fragment;
• transmitting, to a remote server, the redacted document;
• receiving, from the remote server, the redacted document;
• and
• generating an unredacted document by performing a first unredacting operation on the first image fragment, wherein the first undredacting operation is based at least partially on the first redacting operation.

A non-transitory computer storage having stored thereon a computer program, the computer program including executable instructions that instruct a computer system to at least:

• receive a digital image of a scanned document;
• access, from one or more data stores, a division pattern associated with a document type of the document;
• divide the digital image into a plurality of image fragments according to the division pattern;
• select a first image fragment from the plurality of image fragments, wherein the first image fragment is selected based at least in part on a location of the first image fragment within the digital image;
• generate a redacted document by performing a first redacting operation on the first image fragment, wherein the first redacting operation comprises at least one of:
• encrypting, blurring, masking, or inserting a line over all or just a portion of the first image fragment;
• transmit the redacted document to a remote server;
• receive the redacted document;
• and generating an unredacted document by performing a first unredacting operation on the first image fragment, wherein the first undredacting operation is based at least partially on the first redacting operation.
