The vast popularity and useful applications of the QR code were the incentives that encourage the research towards improving its storage capacity and performance. A colored quick response (QR) algorithm is proposed, devised and tested to expand the capacity of the black and white modules to hold colored modules that can fold as many as those available in the 8 bits red-Green-Blue (RGB) color code. Fast Multiplexing Technique (FMT) is established to improve the performance and the storage capacity of the QR color code by multiplexing the black/white QR codes into RGB color shades then folding them into the QR code Modules. Comparative experiments with the classical multiplexing technique-MUX system-proved that FMT has a much better performance, (exponentially faster), while maintaining the capacity multitude to 24 folds that of the classical QR code.

“…For this reason, the QR code was created to represent and protect data based on computer methods. Indeed, the use of web applications and electronic document integrity can be achieved and verified while maintaining user privacy by using improved QR code algorithms, which appear in multiple fields and sectors, including digital signatures, data integrity, security, authenticity, security protocols and data transfer [5]- [7].…”

This paper provides a novel method to improve the data storage of a quick response code (QR code) by applying encrypted lossless compression technology. QR codes are used in several domains, particularly when there is a need to transfer various types of text information. A key aspect of this work is to thus propose a new methodology to overcome the weaknesses of the limited size of the traditional QR code, which has long been an important issue in a wide range of areas. The proposed algorithm incorporates a clear and simple plan for overcoming this difficulty by inserting confidential information into a QR code message. The QR code is updated through the addition of levels that help to share secure messages of various sizes and to authenticate documents for verification and validation. In this work, the newly proposed QR code does not reconstruct the configuration or structure of the QR code. Rather, it provides better security because it relies on the features of the Huffman compression algorithm to reduce the size of the input data and the principles of encryption through the XOR function, which is done through a variable encryption key. The experimental results show the superiority of our method over the previous methods. The scope of this endeavour is thus wide, and there is potential for the encoding of different types of data with a high compression rate in the near future. INDEX TERMS 1D barcode, quick response code (QR code), Huffman coding, security.

“…A study of mobile phones reveal fast pace of changes paralleling spreading mobile usage, across different age groups, places, times and situations [2] this increased usage resulted in the utilization of QR codes in different services because of its speedy recognition and processing [3]. Today, many areas use QR codes such as in authentication of products [4], [5] student result mark sheets and their profile information [6], [7] and banking [8], [9].…”

The modified SHA-1 algorithm was applied in the data integrity verification process of certificates with QR code technology. This paper identified the requirements needed in the certificate verification that uses the modified SHA-1. The application was tested using legitimate and fraudulent certificates. Based on the results, the application successfully generated QR codes, printed certificates, and verified certificates with 100% accuracy. During the trial run of the application, four test cases were seen which involves correct names and QR codes, and three other possible test cases of faking certificates such as modification of the name, regeneration of QR codes using valid hash and a fake name, and modification of the QR code. Although these cases exist, the application successfully verified all thirty certificates correctly. Also, it is noticed that during the scanning, the smartphone camera should be in focus to capture the QR code clearly.
