“…The images are represented in the computer as a Two-Dimensional Array of digital values, each one represents the intensity of a pixel unit. These values are used by the Raster to display on the screen at the location represented by each of these values [9]. This process depends on the number of binary cells used to represent each unit, the most important of which is the representation of (8 bit) or (24bit: 3Bytes) which is the so-called true color representation where each of the bytes represents a color of the three main colors (red, green, blue), and maybe represented by one cell only.…”

Digital data hiding technique is very important in achieving important and sensitive data security, especially those are transmitted through various digital communication channels, it differs from encryption technique, by unperceived or perceived by hackers, as it is based on the principle of hiding those Data within other digital media as their carrier covers. With the development of these hiding techniques, another technique developed to decipher the content of these data, to increase the efficiency of hiding methods of steganography and cryptography techniques should be merged. In this research the distribution of data to be hidden on a set of digital images of the type of BMP was adopted in a random way based on a circular secret key that created randomly and at an agreed length between the sender and the receiver, therefore this method eliminates the suspicion of any confidential content, as well as complicates the data retrieved process.

“…Nevertheless, steganography and cryptography differ in the way they are judged: steganography be unsuccessful when the "enemy" is able to reach the content of the cipher message, while cryptography be unsuccessful when the "enemy" discovers the existence of a secret message in the steganographic medium. The subject of study techniques for decoding cipher messages and discovering hide messages are called Cryptanalysis and Steganalysis [3].…”

Growing the size of attacks that listed during the passing of data between the sending and the receiving has really demand to get high robust method for transfer information in secure manner. Both of cryptography and steganography are familiar and more utilized techniques which process data for encrypt and conceal the secret message, respectively. Two techniques are participating in the same aims and security services like: confidentiality, integrity and availability for secret message from not allowed access. In our paper we focused on the strength of combination between two techniques and this paper presents a new modified fatha in Arabic text in steganography. This method is depend on the existence of Harakt in majority of Arabic alphabets. On this basis, information was hidden in text by modified Fatha which in same direction of original Fatha but with little oriented to be like original one and not be suspicious and observed as abnormal sign. We combined this new stego method with AES encryption.

“…On the other hand, cryptography is the enciphering and deciphering of data and information with a secret code so it cannot be understood [5]. Cryptography fails when the enemy is able to access the content of cipher message; while steganography fails when the enemy detects that there is a secret message present in steganographic medium [6]. The combining of both cryptography and steganography will enhance the security of passwords in password manager.…”

Today's era is the era of Smart phones. Smart phones are continually becoming smaller, more powerful and can perform variety of tasks. The data generated by these devices need to be stored and accessed securely. One example of such sensitive data is password. Computer users are increasingly using password for online accounts, email servers, ecommerce sites, financial services and social media websites and it is always advisable that passwords should be complex and reuse of passwords should be avoided. Therefore this leads to a challenge of remembering several complex passwords for various applications, something an average human being is not very good at. In this paper, a Password Manager, an Android Application is proposed. This password manager takes login credentials (Email Address & Password) as input from user which is then being encrypted using Blowfish algorithm and finally the cipher is stored inside an image selected by user using LSB (least Significant Bit) Technique. A typical password manager uses database to store all login credentials but our proposed approach replaces database with image and stores all login credentials inside an image and in turn providing dual layer security of data that uses combination of both cryptography and steganography in which first layer is to scramble information using Blowfish Algorithm and second layer is insertion of scramble information inside an Image using least significant approach (LSB). Finally, performance analysis of cover-image and stego-image shows that image quality is preserved in terms of MSE and PSNR
