The capability to protect and secure information is dynamic to the growth of electronic trade and to the growth of the Internet itself. A safe data transmission over computer networks can be realized concluded steganography and cryptography. Steganography is a technique used to transmit a secret message from a source to a receiver in a way such that a probable intruder does not suspicious the being on the message. In steganography different-different carrier files can be used, but the most popular is digital images because they are used a proportion now a day on the internet. Steganography helps in the communication of secured data in numerous carries like images, videos and audio. In image steganography the information is hidden entirely in images. A comparative study on pattern based image steganography, one of the drawbacks of most of the current steganography methods is that it changes the bits used for storing color information. A comparative with different three methods of steganography, pixel pattern, 3D pattern, Dynamic pattern. [1,10]In this Paper, means to give an overview of image steganography, its uses and techniques. It also endeavors to classify the requirements of a good steganography algorithm using pattern based and briefly reflects on which steganography techniques are more suitable for this pattern based steganography.

Introduction The communication technologies from place to place has grown at a great speed in recent times. For swapping of data/ information on these days the whole world is depending of high speed, computer networks like the internet which is quite insecure and information can get wide-open. Massive amount of personal data is often collected, used and transferred to third party administrations for a variety of details. Hence, data security is becoming a serious problem in data communication via the Internet or any other media. We can use Steganography, or Cryptography to keep sensitive data. Steganography is regularly considered better than cryptography because the proposed secret message does not attract attention to itself for analysis. 2. Dynamic Pattern Image Steganography Steganography is the art of hiding top-secret evidence in mass media such as image, audio and video. The purpose of steganography is to obscure the existence of the top-secret information in any given medium. This work aims at consolidating the safe keeping in the steganography algorithm by producing dynamic pattern in the selection of pointer arrangement. In addition to this dynamicity is also encompassed in number of bits embedded in data channel. This method has been executed and the consequences have been compared and calculated with current similar methods. In this paper, we propose a Dynamic Pattern based Image Steganography (DPIS) technique for RGB based image steganography. [2,3,5] DPIS technique makes sure lowest capacity for storing top-secret message than existing techniques and it also makes sure that stations containing comparatively lower color standards can store more bits of data. New outcomes show that our technique achieves much better than the existing techniques. In this paper, dynamic pattern based image steganography technique has been brought together. This technique addresses key significant subjects like dynamicity in data embedding and indicator sequence and thus making it problematic to hack by steganalyst. Additionally, it also notices whether the stage image has been altered by an intruder throughout transmission. DPIS technique outcomes in very high capacity with low visual distortions and all this have been proved by new results. DPIS technique has also been compared with important features of other steganography algorithms. ICRAAS 2016
