In this research was to propose a new way to hide data from the text in the tri-dimensional images type depending on the geometric style is proposed, this can be done via the manipulation of the location of the (vertex) in most areas of softness in the triangular object dimensions of any of the many details areas so we make sure not to detect the presence of the data eye human. The experimental results showed, a high rate of failure note the presence of hidden data depending on the scale "RMS" Tripartite-dimensional images, and the way showed good resistance to the types of geometric attack such as "translation"," rotation" and "scaling" and out where he was retrieving a full hidden data without any destruction and this is what boosted "BER".
