摘要：Nowadays, privacy is a demand for every one specially when sending personal information over the internet using social media sites and applications. One way to ensure this privacy is by hiding our personal or secret information inside an image (cover image). Only how knows the hiding process can extract the information from the cover image. To ensure that the cover image must preserve its quality as possible so that no one doubt about it. The process of hiding a text in gray and color image (creating a tag) is used in many important applications. Generally, most methods have been proposed to solve the issue depend on least significant bit (LSB) criteria. LSB methods have a set of negatives and defects in addition to lack of safety of these methods, error ratio between the original image and the text-bearing image ranges from small to large; If the error rate is high, this will lead to distortion in the image which can be observed by the naked eye of the human. Accordingly, to reduce error rate the text message size must be small; the size of the hidden text in the image depends on the size of the image. In this paper, we introduced a novel approach to hide any text independently on the size of cover-image and make the size of the text unrestricted �as it can be larger than the cover-image size�. Our approach provided a high degree of safety with zero error ratio regardless of the size of the text.
