Qtip: For the MaxDiff and Conjoint questions, the predicted duration may vary further due to the way these questions are typically answered by respondents.Ī quick look at a survey containing page after page of boring questions produces a response of “there is no way I’m going to complete this thing.” If a questionnaire is long, the person must either be very interested in the topic, a true bleeding heart, an employee, or paid for their time.

QR code basics: Getting started with QR codes, June 2020. The electronic passport in 2020 and beyond. We also introduce real-world applications where MurQRI can be used effectively and discuss possible methods to enhance security. To support fine-grained access control, we employ attribute-based encryption. MurQRI is designed to store up to 45 kilobytes of data and protect the stored information via biometric authentication and encryption. In this paper, we present a novel approach of employing encrypted multi-layer QR codes, MurQRI (pronounced “Mercury”), for secure user authentication and fine-grained access control in various domains (e.g., airport and hospital). Moreover, it does not provide sufficient storage capacity to employ robust encryption schemes for complex access control and authentication. However, the existing QR code standard is ineffective for security-critical applications (e.g., electronic identity management) as the stored information can be easily exposed to unauthorized parties. Quick Response (QR) codes are widely used due to their versatility and low deployment cost.
