In today’s world, information plays a vital role in any company. Most of the employees, end-users are creating more data about their business. In this case, every company faces a difficulty while protecting the data. For example, when storing the data on the cloud, many issues are encountered, they are data loss, confidentiality, integrity, availability. A variety of data security techniques are there to solve these issues. The most popular techniques are cryptography and steganography. By taking help of these techniques, this research study has proposed a new approach for providing better security and achieving high information storage capacity. The first step is to encrypt the cover image. As a result, the ciphered image will be obtained. Then, steganography will be applied for embedding the information. Two different algorithms have been used in this proposed model. Further, the proposed method will be analyzed by calculating the Peak Signal to Noise Ratio (PSNR) values and histogram.
