-This study proposed a combination of steganography and cryptography techniques using LSB-RSA method. RSA is a popular cryptographic technique that can be applied to digital imagery. Digital image pixel values range from 0 to 255, making the keys used in RSA limited enough to be less secure. It is proposed to convert pixel image value to 16 bits so that the key used can be more varied. Experimental results prove that there is a steady increase in security and imperceptibility. This is shown by the results of PSNR 57.2258dB, MSE 0.1232dB, this method is also resistant to salt and pepper attacks. [6]. Domain spasial lebih rentan terhahap serang dan informasi pesan mudah hilang ketika terjadi manipulasi citra. Penyembunyian pesan dengan menggunakan metode LSB sangat sederhana karena hanya mengubah nilai bit terakhir dengan bit pesan. Namun, teknik ini dapat menghasilkan citra yang sangat mirip dengan citra aslinya sehingga indra penglihatan manusia tidak dapat mendeteksi perubahan pada citra dan mustahil untuk memersepsikan pesan secara langsung [5], [6].Namun, cepatnya perkembangan teknologi tidak menutup kemungkinan pihak yang tidak berkepentingan dapat mengekstraksi pesan dari citra cover. Oleh karena itu, diperlukan pengamanan lebih pada pesan yang disembunyikan. Pada beberapa penelitian sebelumnya telah banyak diusulkan kombinasi teknik steganografi dan kriptografi, seperti dalam [6]- [9]. Kriptografi sendiri adalah sebuah seni penyandian pesan dengan mengacak sebuah pesan menjadi sedemikian rupa sehingga maksud dari pesan tersebut tidak dimengerti oleh orang lain [10].

“…Steganography is a technique for hiding digital messages into other digital media, such as images, audio, video, and others so that the messages can be disguised and not directly visible to the human vision. There are two kinds of steganography by domain, i.e., spatial domain and frequency domain [7]. Least Significant Bit (LSB) is a popular method in spatial domains [8].…”

The Internet is a public network with many issues of data transfer security. Steganography is a data transmission security technique that is done by hiding the message in a container media, such as an image. The media certainly has its limited payload to accommodate the embedded data. This paper proposes a method for increasing the payload of secret messages in an image. The edge area is used to accommodate more message bits because the image edge area can better tolerate pixel value changes. In this research paper, Canny and Sobel detectors are combined to get a wider edge area. This two-detector combined method provides a larger edge area for greater payload of messages while maintaining imperceptibility of stegoimages.

“…Namely, it can be not only used to encrypt the data, but also can be used for identity authentication. Therefore, RSA signature is one of the most common digital signature methods [2]. The advancements in technology and software since the last decade made it easy to copy or alter the contents of digital images.…”

Authentication of digital media has been done with the various scheme, one of them is a digital signature. The digital signature attached by the sender to the document can be used as a tool to ensure that the submitted document is authentic or not manipulated. So research on digital signatures should be developed to improve its ability to provide security and prove the authenticity of the image. Cryptography is one of the most popular fields of study these days as it is necessary to maintain the confidentiality of the data which is sent over the network. Cryptography is the only powerful tool for achieving high levels of information security in a computer networks environment. Cryptography can support implementation of all these security services, by using various cryptographic techniques, which include among other things conventional secret key algorithms, public-key algorithms, authentication procedures, and different digital signature schemes. Each of these methods has its own shortcomings. A new scheme for evaluating the cryptographic security. so research on digital signatures should be developed to improve its ability to provide security and prove the authenticity of the image. This paper sets out to contribute to the general body of in the area of cryptography application and by a new way of implementing. This paper research a combination of three algorithms to the created digital signature, namely: Rivest -Shamir -Adleman (RSA), Vigenere Cipher and Message Digest 5 (MD 5).By combining these three algorithms, the data security level becomes stronger. This algorithm can protect from image forgery or various image manipulations.
