Cloud-based secured QR code for self-service access control system at resort and hotels

Abstract

Self-service technologies (SSTs) are increasingly becoming popular with the advancement of mobile technologies, cheaper Internet prices and the growing popularity of mobile devices in daily life. Popular hotels/resorts tend to adopt SSTs to enhance their service quality standards, consumer experience, loyalty and most importantly overall customer satisfaction. The long queue in hotels and resorts has been the major problem for causing dissatisfaction for customers, especially for minors and senior citizen. Customer satisfaction has been the main criteria for the business to grow. With this goal, we propose a cloud-based secure access control for hotel and resort rooms using the QR code technique. To gain access to the hotel room, the customer needs just to scan the QR code sent from the secure cloud. The user details are encrypted using MD5 algorithm and stored as checksum in database to avoid various attacks such as phishing, malware, code injections and others possible in Web services. When the user scans the QR and decodes, it compares the checksum stored in database. In case of any discrepancies, further process is stopped and hence makes our approach more secure from other techniques. Also, cloud provides additional security for the Web services.
