The article deals with the steganography system which hides text inside images without losing data. The secret message is hidden in the cover image using Least Significant Bit (LSB) algorithm. To evaluate steganography system properties the measures like Signal-to-Noise Ratio (SNR), Peak Signal-to-Noise Ratio (PRSN), Mean Squared Error (MSE) and Structural Similarity Index for measuring (SSIM) are used. Experimental results show the advantages of the described steganography system.

The report examines the use of steganography as a method of hiding text, images or sound recordings in file-carrier for mobile devices, which may give the opportunity to keep the correspondence without awaking any suspicion. The information file is hidden in the filecarrier by the method Least significant bit (LSB) through various algorithms of coding. The experimental part compares mobile applications, which are using Steganography methods and compares their advantages. The experimental results show that the Ultra Mobile Steganography is realizing with fast pace, the applications have common static characteristics of the cypher image and are easy to use.
