SYSTEM AND METHOD FOR ENCODING AND AUTHENTICATING A DIGITAL IMAGE

摘要

An encoding apparatus partitions a digital image into multiple regions for subsequent encoding. A first encryption code is associated with a first region, a second encryption code is associated with a second region and the first code, and a third code is associated with the first code, the second code and a third region. An authentication apparatus authenticates the digital image in an inverse process.

主权项

1. A method for encoding a digital image, comprising:
capturing a digital image comprising a plurality of pixel rows; partitioning the digital image into a first plurality of pixel rows, a second plurality of pixel rows, and a remaining pixel row; generating a first code from the first plurality of pixel rows; overlaying the second plurality of pixel rows with an image representing the first code; generating a second code from the second plurality of pixel rows; generating a third code based on the first code and the second code; and encoding the first code, the second code and the third code into the remaining row of pixels.
