This paper presents the issues and challenges faced for image steganographic techniques. Many LSB method techniques were developed in recent year using direct or un-direct position to embed secret message into cover. Some techniques for embedding information in Image files were reviewed, and recommendations are being proposed for the best strategy of hide information in image files and the possibility of finding other new techniques hiding information in image files. | International Journal of Computer Networks and Communications Security VOL. 3, NO. 9, SEPTEMBER 2015, 363–366 Available online at: E-ISSN 2308-9830 (Online) / ISSN 2410-0595 (Print) A Various Issues in Image Steganography that Using LSB Technique Mohammed Salem Atoum1 and Mohammed M.

Many LSB method techniques were developed in recent year using direct or un-direct position to embed secret message into cover. Some techniques for embedding information in Image files were reviewed, and recommendations are being proposed for the best strategy of hide information in image files and the possibility of finding other new techniques hiding information in image files.

In LSB Method the cover and secret message are converted into streams of bits and then later the secret message is embedded into the cover by replacing the LSB bit of the cover with one or more bit of the secret massage and then sent to receiver. In order for the receiver to extract secret massage the receiver accesses the sequence of sample indices used in the embedding process [1-8]. However, in following some methods using LSB technique in steganography were explained: 2 STANDARD LSB In this method researcher embedded one bit or more from secret message in cover directly. This is way simplicity and easy to detect and extract secret message. To enhancement the security of LSB standard, some researcher using Intermediate Significant Bit and Most Significant Bit (ISB and MSBA). In [9] developed LSB method to .
