METHOD AND SYSTEM FOR EMBEDDING DATA IN A TEXT DOCUMENT |
摘要 |
The present invention relates to a method and system of embedding data in text documents. The method includes obtaining a document having dimensions and at least a first character and a second character and determining a length between the first character and the second character to define an inter-character space. A reference length is determined, where the reference length is a function of the dimensions of the text document. A threshold length is determined, where the threshold length is a minimum length wherein information is not encoded in the inter-character space if the inter-character space is not within the threshold length. The information is encoded into an altered inter-character space wherein a length of the altered inter-character space is an integral multiple of the reference length or a non-integral multiple of the reference length. |

1. A method of encoding information in text documents, the method comprising:
obtaining a text document having dimensions and at least a first character and a second character; determining a length between the first character and the second character to define an inter-character space; determining a reference length, the reference length being a function of the dimensions; determining a threshold length, the threshold length being a minimum length wherein information is not encoded in the inter-character space when the inter-character space is less than the threshold length; encoding the information into an altered inter-character space wherein a length of the altered inter-character space is an integral multiple of the reference length or a non-integral multiple of the reference length. |
