Interaction with medical data using QR-codes

Bar-codes and QR-codes (Quick Response) are often used in healthcare. In this paper an application of QR-codes to exchange of laboratory results is presented. The secure data exchange is proposed between a laboratory and a patient and between a patient and Electronic Health Records. Advanced Encryption Standard was used to provide security of data encapsulated within a QR-code. The experimental setup, named labSeq is described. Additionally, a mobile application which enables decoding and storage of the enciphered information is presented. This work is also a preliminary research in supplying electronic glasses device, eGlasses, a functionality to process data from graphical patterns. In this paper a mobile phone is used as a simulator of electronic glasses. The exchange of data between the mobile application and Electronic Health Records is based on Health Level 7 standards or using JavaScript Object Notation. This enables fast integration of data between a patient´s device and the information system used by a healthcare professional.
