The security of data over the internet is a crucial thing specially if this data is personal or confidential. The transmitted data can be intercepted during its journey from device to another. For that reason, we are willing to develop a simple method to secure data. Data encryption is one method to secure the messages but the intruders can still try to crack it, in order to overcome this, steganography has been used to hide the data into a cover media(i.e. audio, image or video). Recently steganography attracts many researchers as a hot topic. This paper proposes an advanced technique for encrypting data using Advanced Encryption System (AES) and hiding the data using Haar Discreet Wavelet Transform (HDWT). HDWT aims to decrease the complexity in image steganology while providing less image distortion and lesser detectability. One-forth of the image carrying the details of the image in a region and other three regions carrying a less details of the image then the cipher text is concealed at most two Least Significant Bits (LSB) positions in the less detailed regions of the carrier image, if the message doesnu0027t fit in the first LSB only it will use the second LSB. This proposed algorithm covers almost all type of symbols and alphabets.
