Abstract
A computer system for the creation of subliminal image or watermarks where the apparent video is an “obvious” image and a subliminal or “clandestine” image or watermark is hidden within the data structure. The concept is envisioned for the cloaking of images, sound, video or like digitized non-coded information. The cloaked files may be intended for storage, transmission, or clandestine placement in a public file system. The watermark may be used for the subliminal marking of a source of a file, its creation, or for tagging copyrighted information.
Claims14
A method for encoding data in an image, the method comprising:
- identifying a first numeric value for each pixel in a pair of two substantially identical pixels in a first image, wherein a portion of the first numeric value for each pixel in the pair comprises encoded data;
- replacing a portion of the first numeric value for each pixel in the pair with a second numeric value corresponding to encoded data to yield an updated numeric value for each pixel;
- providing a second image comprising the pair of two substantially identical pixels and all remaining pixels in the first image, wherein each pixel in the pair comprises the updated numeric values;
- and
- extracting the encoded data from the updated numeric values, the extracting including:
- inverting the first numeric value for each pixel in the pair to yield an inverted updated value;
- summing the inverted updated value and the first numeric value of the remaining pixel in the pair to yield a summed numeric value;
- and
- converting the summed numeric value into the encoded data.
A system, comprising:
- a processor;
- and
- a non-transitory computer-readable medium having stored thereon instructions for causing the processor to:
- identify a first numeric value for each pixel in a pair of two substantially identical pixels in a first image, wherein a portion of the first numeric value for each pixel in the pair comprises encoded data;
- replace a portion of the first numeric value for each pixel in the pair with a second numeric value corresponding to encoded data to yield an updated numeric value for each pixel;
- provide a second image comprising the pair of two substantially identical pixels and all remaining pixels in the first image, wherein each pixel in the pair comprises the updated numeric values;
- and
- extract the encoded data from the updated numeric values, the extracting including:
- inverting the first numeric value for each pixel in the pair to yield an inverted updated value;
- summing the inverted updated value and the first numeric value of the remaining pixel in the pair to yield a summed numeric value;
- and
- converting the summed numeric value into the encoded data.
A non-transitory machine-readable medium having stored thereon instructions for performing a method of encoding data in a first image, the non-transitory machine-readable medium comprising machine executable code, which, when executed by at least one machine, causes the machine to:
- identify a first numeric value for each pixel in a pair of two substantially identical pixels in the first image, wherein a portion of the first numeric value for each pixel in the pair comprises encoded data;
- replace a portion of the first numeric value for each pixel in the pair with a second numeric value corresponding to encoded data to yield an updated numeric value for each pixel;
- provide a second image comprising the pair of two substantially identical pixels and all remaining pixels in the first image, wherein each pixel in the pair comprises the updated numeric values;
- and
- extract the encoded data from the updated numeric values, the extracting including:
- inverting the first numeric value for each pixel in the pair to yield an inverted updated value;
- summing the inverted updated value and the first numeric value of the remaining pixel in the pair to yield a summed numeric value;
- and
- converting the summed numeric value into the encoded data.
