    A Multi-layer Cryptosystem for Secure Data Transmission Using PRNG
    (IEEE, 2020-12) Islam, Md. Ashiqul; Md. Shourov, Sarker; Hossen, Md. Sagar; Mridul, Aunik Hasan; Hasib, Md. Abdul; Jabiullah, Md. Ismail
    Nowadays the usage of the Internet is developing day by day. One of the largest uses of the internet is to transfer data from different sources to different states. During data transfer over the internet, a major issues arises with data protection. When transferring data over the internet with security that is called data security. Two techniques are used in data protection. Cryptography and Steganography. In our proposed system Cryptography and Steganography are combine used for making the data more secure. The basic function of Cryptography is encryption and decryption. Here, the message is encrypted more than 4 Times. Basically in Cryptography method the secret message are encrypted with an encryption key. The sender uses the encryption key for sending a message. On the other hand, the receiver should know the encryption key for decrypting the message to get the original data. Instantly Steganography is the way to hides secret data using digital media cover such as Audio, Image and Video and Text. In our proposed system, Color Image has been used for embedding the secrete message. In the proposed technique mostly used random binary digit from multiple pixel instead of LSB technique after converting the stego image into a binary form. Before embedding the secret message the Robust Cryptography Algorithm Advanced Encryption Standard (AES) & Pseudorandom Number Generator (PRNG) has been used to encrypting the secret message and secure the confidential data from the unauthorized access.

    Regarding the development of modern technology, we are not only using the machine but also, we are connected with it in so many ways. For different reasons, the products which are producing from software industries is not significantly gratifying the customers. We require significant change in the context of what we currently producing. The change is essential not only in software based documentation but also in hardware, which will be effective regarding what the customer is required. Indeed, it has to be very prudent, effective, and more productive than ever before. The most sensible thing in the world today is the smartphones that we all have. The dependency towards the smartphones is incalculable, moreover, we are living our every day with it. Imagine, how fantastic it would be if a project can be developed, which would be robot based on hardware and also perform a number of intellectual tasks through the assist of a smart device. The robot would actually be able to perform the tasks through simple voice recognition system including wireless connection. This research is all about the procedure and the knowledge regarding a robot that performs Facial Recognition with a voice control mechanism by a smart device, voice controller via smartphone.
