Abstract
We can easily observe that in the current era of communication, Computers, mobile phones, and the Internet are widely used mediums. In such an environment, information security is an important issue. The most common techniques used for information security are Cryptography and Steganography. Many research works have been done on image Steganography. These images have different kinds of formats like BMP, GIF, and PNG. Several compression methods are available which applied to the images having the format BMP, GIF, and PNG is comparatively less effective than the JPEG image. JPEG compression steganography method is complex to implement even then some algorithms have been developed for it. They provide single-level or two-level information securities. This paper presents a method in which is the combination of Cryptography and Steganography is used over android mobile phones. Here we are performing encryption two times on data to be hidden and then that encrypted data hidden both in text and image. We are using the Advanced Encryption Standard (AES) algorithm to hide text within a text, Discrete Cosine transform (DCT) for image steganography, and Data Encryption Standard (DES) for encryption of text. This paper gives the idea of three-level information security over the android environment.
Highlights
Information security is a popular research area
As we know that technologies have been improving in the field of communication, its result is that many microdevices have arrived in the market
When we see the previous work we found that very little work has been done over JPEG image format in the android environment and whatever the work has done they have to provide only one level or two-level security
Summary
Information security is a popular research area. It attracted researchers towards the security concept of data by using different kinds of techniques. Information security attracted many researchers and has become the widely scoped area of research in wireless and mobile communication. The field of Steganography is very vast, but researchers have been motivated toward mobile steganography because of the intensive use of mobile phones as well as the exchange of information among the users. The multimedia message was introduced and gained more popularity due to its advanced features. Smartphones have come to light with many advanced features for communication. It is a small handy portable device that the user can carry with him anywhere. We have described few data security techniques earlier in which one of the trendiest techniques is steganography
