Abstract
The secret Electronic Mail messages encounter many problems that causes hacking or modifies it, therefore is necessary to find active ways, to keep it out of hackers and intruders, hiding technique was applied to satisfying that.
The Traditional ways depend on hiding secret message data in between words or statements of carrier message, after dividing its characters values in to sequence of bits, was leaving one or two spaces depending on hided bit value (0 or 1).
In this research, a new concept was applied to create only one space in this two cases, this method carried out higher performance than traditional methods, there is no perceptual hiding for hackers and intruders, and satisfied full matching in figure and size of carrier message before and after hiding.
