“…Not only that QR codes are also resistant to damage, because the QR code is able to correct the error up to 30%. Although some symbol of the QR code is dirty or damaged, the data can still be stored and read [10] [11]. Three square-shaped marks in three corners have a function so that the symbol can be read with the same results from any angle throughout 360 degrees [12].…”

Hospital is an organization that primarily provides services in the form of examination, treatment, medical treatment and other diagnostic measures required by each patient in the limits of the technology and the means provided by the hospital. So that patients get the maximum service, hospitals have to provide the best services, one of the services that are being highlighted is the queue system. This study proposed a queue control system at the hospital using a quick response code (QR Code) as verification of the patient's arrival that serves to speed up the administrative process and provide effective services, to facilitate the patient in terms of the queuing line (registration) at the hospital. The queue control system uses the website as a registration and database repository for patient data. This website has two kinds of display form, as a patient or a doctor. This kind of display is useful to speed up the administrative process, so that registration can be done at any time by the patient, with patient entering/filling data themselves and their complaints or medical records that are automatically available on the website, so that patients do not need to come to the hospital with a medical record. Furthermore, the website will filter the data entered by the patient as the patient's complaints, so that patients can choose the hospital that provides services for patients' illness complaints which are also showing hospital addresses to facilitate patients in finding the location of the hospital. After the administration process on the website, the system will provide a QR Code as a form of verification for patients who have registered, with their data already exists in the database. When the patient arrives at the hospital, the patient only needs to scan the QR code that already exists, without taking care of the administration back because at the time the system gives a QR Code, indicating that patients already had a hospital destination along with the queue number. It is expected that the queue control system implemented at the hospital using a quick response code (QR Code) as verification of the patient's arrival, could speed up the administrative process to be more effective and efficient.

“…However, the QR code detection is still problem at low contrast and variable illumination [15–19]. To detect the four vertex coordinates of QR code image, many effective algorithms are proposed in the literature [20–25].…”

“…QR Codes have become vastly used via the rapid growing of mobile Internet and the expansion of QR Codes applications. There are many advantages that characterize the QR Code; Firstly, it is readable very faster even under low contrast conditions and this feature allows the direct marking, also it can be scanned at any angle; Secondly, it has a high data capacity of storage since it takes minimum space; Thirdly, it can handle different kinds of data; Fourthly, the QR Codes enable powerful encoding even if up to 30 % of the data is damaged; Finally, the availability of QR Codes for everyone led to wide range of utilizations and applications [1]. Digital watermarking takes an important area due to the challenges accomplished in the efficient inclusion of the watermark bits on a limited size of image intensity values [2], [3], [4].…”

With the quick arrival of high grades of acceptance, the QR Code technology is becoming more adaptable and usable every day by more and more people. Lately, the utilization of two dimensional QR codes for the powerful encoding of information with a big capacity becomes significantly growing; especially for encoding the identity. Because the identity is private information, it requires being further authenticated. This paper firstly works on analyzing the content of the QR Code and finding the unimportant locations inside it; Then, a combination of the digital watermarking concept and QR Code technology is used to substitute the founded unimportant locations by the watermark for the purpose of increasing the authenticity for the owner of the identity. The experimental results show that the inclusion of watermark bits inside the detected unimportant locations did not affect the process of decoding and retrieving information from the QR Code.
