<p align="center"><strong><em>Abstract</em></strong></p><p><em>There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. One of the vulnerable parts of data security is when sending data to the destination. At the time of delivery, tapping of data can occur, so that people who are not entitled to get that information can find out. Therefore, an information needs to be secured so that only people who have access rights can know or get that information. And to maintain the confidentiality of the information, one of the ways is to insert the data into other objects, so that other people do not realize if the object contains important data or information. This hiding method is also known as steganography, and cryptography is added to strengthen the security of the data, that is a science and art to maintain the confidentiality of the message by encoding it in a form that is incomprehensible. The method used in steganography is Least Significant Bit (LSB), the algorithm used in cryptography is the Advanced Encryption Standard (AES), and the software development method used is prototype.

Recently, the rate of data transfer over the internet globally has increased and this called for more data security as security of data is of great concern for individuals as well as business owners. Cryptography and steganography are two major key players for data security technique. Cryptography is use to perform encryption on the secrete message while steganography hides the secrete message in digital media, image in this regards. This paper employed these two techniques using Advanced Encryption Standard (AES) for the cryptography and Least Significant Bit (LSB) for the steganography. Combining the two algorithms ensured data integrity, data security, and flexibility. The changes in the secrete message carrier (Stego) is insignificant and is often not noticeable by the nicked eyes, thus this make the interception of the message often difficult by intruder.

There is a great research in the field of data security these days. Storing information digitally in the cloud and transferring it over the internet proposes risks of disclosure and unauthorized access; thus, users, organizations, and businesses are adapting new technology and methods to protect their data from breaches. In this paper, we introduce a method to provide higher security for data transferred over the internet, or information based in the cloud. The introduced method for the most part depends on the Advanced Encryption Standard (AES) algorithm, which is currently the standard for secret key encryption. A standardized version of the algorithm was used by The Federal Information Processing Standard 197 called Rijndael for the AES. The AES algorithm processes data through a combination of exclusive-OR operations (XOR), octet substitution with an S-box, row and column rotations, and MixColumn operations. The fact that the algorithm could be easily implemented and run on a regular computer in a reasonable amount of time made it highly favorable and successful. In this paper, the proposed method provides a new dimension of security to the AES algorithm by securing the key itself such that even when the key is disclosed; the text cannot be deciphered. This is done by enciphering the key using Output Feedback Block Mode Operation. This introduces a new level of security to the key in a way, in which deciphering the data requires prior knowledge of the key and the algorithm used to encipher the key for the purpose of deciphering the transferred text.

AbstractData security is an important factor in an electronic transaction, because the data sent must only be known to the person who is entitled to receive the information. There are several security aspects of the data that must be maintained, such as: authentication, integrity, non repudiation, authority, confidentialty, privacy and access control. Therefore we are need for a system that is capable of carrying out some of these aspects. One technique that can be used in maintaining data security is steganography with the LSB (Least Significant Bit) method. In addition, to strengthen the confidentiality of the hidden information in steganography needed Additional techniques in the form of cryptography namely RC4 (Rivest Code 4). In this research,, the researcher  used a software development model is a prototype. And for the tools used in developing this application is an Unified Modeling Language. The results of the research conducted by researchers are the application of steganography using the LSB (Least Significant Bit) method combined with RC4 cryptography (Rivest Code 4) proven to be able to hide and secure important information from people who do not have access rights to that information. Keywords: Steganography, Criptography, Data Security

Data security is a way to ensure that stored data is safe from corruption and that access to it is accordingly controlled. Data security helps to ensure privacy. It also helps protect personal data from theft. Data theft is one that often occurs on global computer networks. It includes criminal acts in the internet world. Chronology of theft is that an intruder enters a system and retrieves essential information without the owner's knowledge. Intruders use data that has been taken for various crimes. Various ways that intruders take to retrieve the data. This action is proven by the amount of internet traffic that is looking for a gap to infiltrate a system. Cryptography is needed to protect essential data. One of the classic algorithms used is Gronsfeld Cipher. This algorithm works by exchanging characters in messages using substitution tables. The key used is a number that determines the shift of plaintext and key. The resulting ciphertext is the result of plaintext substitution with the key table. This algorithm is constructive for users to secure their essential information when it will be sent through a global network.

<p>Information is a vitalthing that needs to be secured and well protected during transmission between two or more parties over the internet. This can be achieved by steganography technology. Steganography is the concealing science in which the information is concealed inside other information in a way that the concealed information cannot be detectable by the human eye. Many ways are available to hide data inside a cover media for example text, image, and audio steganography, but image steganography is the most utilized technique among the others. Secure image steganography has a high-security level than traditional technique by combining steganography with cryptography due to encrypting secret information by cryptography algorithm before embedding it into the cover media by steganography algorithm. In this paper,a systematic review has been presented about secure image steganography and its renowned types. Many researchers proposed secure image steganography by using various cryptography and steganography algorithms which have been reviewed. The least significant bit ‘LSB’ was the renowned steganography algorithm which has been used by researchers due to its simplicity, while various cryptography algorithms like advanced encryption standard (AES) and blowfishhave been used to propose secure image steganography in the reviewed papers. The comparison among the reviewed papers indicated that the LSB with hash-RSA gave a greater peak signal-noise ratio ‘PSNR’ value than the others which was 74.0189 dB.</p>
