Steganography of Images Using Android

Abstract

Stenography is used to conceal one media file within another. Providing security to a system as a whole is what it means to authenticate it. Getting private subtleties on the portable stages has been turning into a regular issue for the experts In this technique the picture coding is suggested that conceals the data along a chose pixel will be pixel and on the following worth of the chose pixel, that is to say, pixel+1. There are some drawbacks and limitations to this method. A novel approach to increasing system security is proposed as a means of overcoming the drawback. The stenography method will be utilized in this paper to conceal the text message within an image. All crucial data, including passwords, is encrypted and transported in an image, making it challenging to decipher. The 7th Bit of a Pixel embedding technique is the most fundamental and crucial image stenography technique. A mathematical algorithm is applied to the seventh bit of an image's pixels based on the image's seventh bit, resulting in the generation of a temporary variable (pixel + 1). In order to provide a high level of security for Android's authentication system, the seventh bit of the selected pixel and the seventh bit of the pixel plus one are utilized for information concealment and encryption. When contrasted with other techniques that are currently in use, the outcomes of this proposed image stenography method are both intriguing and promising.
