“…Skema kriptografi visual (𝑘, 𝑛) adalah sebuah teknik kriptografi dimana citra digital dibagi ke dalam 𝑛 shares yang dilakukan dengan komputasi kriptografi dimana untuk mendekripsi citra diperlukan minimal 𝑘 buah citra hasil tersebut. Jika terdapat 𝑞 citra hasil, dimana 𝑞 < 𝑘, maka tidak ada informasi apapun yang dapat diperoleh tentang citra asli [10].…”

“…Matriks yang telah dipilih merupakan representasi dari m subpixel yang terletak pada masing-masing n transparansi. Solusi benar apabila memenuhi seluruh kondisi berikut [10]: Kriptografi visual skema ((n-1,1),n) merupakan skema kriptografi dimana (n-1) natural image digunakan sebagai input untuk menghasilkan n buah shares, angka 1 menunjukkan jumlah secret image, sementara n menunjukkan jumlah shares yang dihasilkan yaitu natural share image dan share image hasil pembentukan share. Proses pembentukan share dilakukan dengan melakukan ekstraksi fitur untuk masing-masing dari (n-1) natural image sehingga menghasilkan (n-1) natural share image, kemudian dilakukan penggabungan.…”

Skema kriptografi visual ((n-1,1),n) menggunakan (n-1) natural image untuk menghasilkan n buah shares. Skema ini dapat mengatasi ekspansi piksel dan rekonstruksi dapat dilakukan tanpa distorsi. Namun, share yang dihasilkan akan menimbulkan kecurigaan pihak lain karena bersifat acak. Untuk itu perlu dilakukan pengamplopan dengan teknik steganografi untuk menyembunyikan shares yang sudah diacak tersebut. Dalam penelitian ini dilakukan pengamplopan share dengan teknik steganografi model warna Hue-Saturation-Intensity (HSI) berbasis LSB. Kelebihan dari model HSI adalah sesuai untuk menggambarkan warna berdasarkan interpretasi manusia dan komponen intensitas tidak berkorelasi dengan komponen hue dan saturation. Lebih jauh, model HSI dapat menampung yang lebih banyak serta proses ekstraksi yang lebih rumit disbanding warna lain.??? ??? Namun, pengamanan tersebut tidaklah cukup, karena pihak yang tidak berkepentingan dapat memperoleh secret image hanya dengan melakukan konversi dan rekonstruksi. Oleh karena itu, sistem dilengkapi dengan password, sehingga tidak sembarang orang dapat membuka amplop yang berisi share. Hasil pengujian menunjukkan penyembunyian shares model warna HSI dan penambahan password dapat meningkatkan keamanan kriptografi visual. Terhadap stego image juga dilakukan serangan noise dengan empat jenis distribusi dan pengujian menunjukkan bahwa distribusi Gauss lebih tangguh disbanding yang lain.

“…In a similar manner, we can also generate n shares and out of which we will use only k significant shares in order to generate the secret image, where k <= n. Kandar and Dhara [9] proposed (k, n) secret sharing method for RGB images. Here, for a white pixel, (n − k) + 1 number of shares will have the same white pixel at the same pixel location while keeping the pixel as black for remaining shares.…”

Image encryption is one of the most promising fields of research in the conventional scientific society. Visual cryptography is a secured encryption technique which is used to encrypt a secret image based on share generation and superimposition rather than computing. This overcomes the burden of computation but the mammoth risk of attackers is superfluous to the passing of shares in sequence through the communication channel. However, this superimposing problem can be resolved by cracking some additional encryption algorithms alongside the visual cryptography. In this paper, we propose a highly secured visual cryptography scheme which uses encryption and error diffusion halftoning algorithms as intermediate steps in cryptography work. We have also done the comparative analysis in order to select the most optimum technique, among the available algorithms according to the requirement of the system. The proposed work has been tested on various formats of standard color images of varied resolutions and proven more secured than contemporary techniques.

Abstract-Visible Light is regarded as a reliable mode of communication in comparison with Radio Frequency communication. It has a great scope in 5G networks. But this visible light communication is prone to security issues like eavesdropping due to its visual nature. This paper deals with the light encryption scheme using Light Emitting Diode. Keywords: Security, Visual Cryptography, Otsu, Halftone, Lifi I.INTRODUCTION As the technology rules the world currently, security plays a very vital role in data transfer. This can be provided by means of Network security. Cryptography is a study of mathematical technique that relates the aspects of security issues like Data confidentiality, Data Integrity and Data Availability which is referred to as CIA triangle. Visual Cryptography is a new technique of providing information security using simple user algorithms. Complex, computationally intensive algorithm is not used in this technique as used in the traditional cryptographic techniques. As images are more attractive than text, they are more prone to hacking nowadays. The security should be provided for Visible Light Communication of image transmission. As far as now the security for image transmission in VLC was provided by an Otsu algorithm which has enhanced Bit Error Rate but has a limitation on computational time and image sharing scheme. This can be overcome by an Image security algorithm called halftone algorithm. The proposed idea will overcome the limitations that were mentioned above. Figure1 represents the light encryption system using laptops. The VLC signal from a LED can be received by a light encrypting device like mobile or laptops, which could be any device that has a optical receiver such as photodiode or an camera image sensor, and also having a visible LED for optical transmitter. After the visible light signal from LED is received by the light encrypted device, the image data can be encrypted by applying halftone algorithm followed by an XOR cipher. This ensures double encrypted security for the data to be sent. The above implementation could be made possible for the future VLC medium.
