Claim One:
1. A method for embedding information in an image, the method comprising: defining a code corresponding to a unit of content, the code comprising at least one character; defining a cryptographic representation for each character of the at least one character in the code, each cryptographic representation comprising a group of regularly spaced mark locations, wherein the mark locations comprise a fixed distance between mark locations, each mark location having a mark selected from one of a nonnative mark and a native mark, a native mark having an intensity value the same as a native intensity of a location in the image corresponding to a location of the native mark and a nonnative mark comprises a marking added to the image that has a perceptible difference between a native intensity value at a location of the nonnative mark and an intensity value of the marking added to the image, wherein a pattern of marks in the group of regularly spaced mark locations is unique to each character of the at least one character in the code; and embedding the cryptographic representation for each character of the at least one character of the code into at least a portion of an image, wherein, when the image is captured with a capturing module, a distance between mark locations in the image from the perspective of the capturing module indicates an orientation of the image with respect to the capturing module, wherein changes to perceived distances between mark locations from the perspective of the capturing module indicate orientation of the image with respect to the capturing module and the orientation of the image is the current positioning of the image, wherein the image can be in various positions.
