“…Names, addresses of residence, birthdates, marital statusall these data should be kept in a secured way. However, to protect a printed document from unauthorized access is much harder than to ensure information security in a computer system where a document security management system can be used and both cryptography and steganography can be applied [12,13].…”

Background. Nowadays, matrix barcodes in general and QR codes in particular are widely used in multiple applications, when it is important to input data into a computer system in a fast and secure way (both error-free and protected from third parties). Their popularity was significantly increased since the era of smartphones had begun, and so consequently, new use cases and new problems have arisen. Specifically, one of the important issues is representing more information as a barcode symbol. Objective. The objective of the research is to develop a data barcoding method based on grayscale tricolor 2D barcode which enables representing more amounts of information with preservation of the area of a graphical symbol. Methods. The research is based on both the coding theory and the multicolor barcode concept, which allow to increase amounts of data that can be encoded and represented by one matrix barcode symbol. The proposed BGW barcoding method uses a combination of data transformations between several notation systems with the purpose of data compression.Results. The method of data encoding based on tricolor matrix barcodes is proposed and described. This method allows to compress input alphanumeric data and transform it into a 2D barcode symbol composed of BGW (black, gray, white) barcode patterns. Two use cases for the proposed method application are considered in the paper. The first use case concerns enhanced information input. The second one addresses the data protection issue. Conclusions. The proposed BGW barcoding method enables compact representation of a textual data. One of the benefits of the proposed method lies in a possibility to not only encode data but to compress it. Due to data compression, more information can be represented keeping the same dimensions of the graphically coded symbol. Depending on the parameters, especially barcode symbol digital capacity, compression can be up to 20-25%.

“…A hybrid encryption technique that uses permutation of text and image based on hyperchaotic scheme is proposed in [8]. Smita et al, in [9] has described a hybrid encryption technique that makes use of DES and RSA for text data. Pia Singh, in [10] has given a method to encrypt and decrypt image using blowfish.…”

Cloud Data's are vulnerable to malicious threats. Among the data that are stored in cloud, patient record stored by hospitals is profound to be sensitive. Security breaches are common in public cloud. In order to address this issue, a novel hybrid approach is provided in this paper. New round functions are introduced to increase the security level. To encrypt text data, stream cipher Chacha is utilized. Though Chacha cipher has been cryptanalyzed by many authors, still it is not feasible to attack this cipher in polynomial time. Next, to secure the scan images of the patients, two different encryption algorithms are utilized, namely, Advanced encryption standard (AES) and Blowfish. The encrypted data and images are finally stored in the cloud. It is observed that even if the adversary gets hold of the data, they cannot decipher to the original data in polynomial runtime.

Abstract-The purpose of this study is to implement and observe parameters like time and memory for implementation of multi-level encryption using the Data Encryption Standard (DES) and a modified version of the RSA Algorithm, the multi-prime RSA. The average values are calculated for each parameter after using a different number of primes and the results have been illustrated graphically and in tabular form for clarity of conclusions. The advantages and reasoning for using this approach have also been listed in the study.
