| dc.description.abstract | All systems do not require security at the same level. Sensitive information such as financial transactions require higher level of security in terms of confidentiality, integrity and availability. Mobile Financial Service (MFS) is making financial transaction using mobile devices. Due to the inherent nature of MFS using wireless technology, it makes the service susceptible to different attacks. Currently, in Ethiopia mobile financial service is mostly being provided using Unstructured Supplementary Service Data (USSD) technology. This study first identified many vulnerabilities and possible attacks that can be made on the current scheme by reviewing existing literatures. On top of this, analysis of existing MFS technologies has been made. Accordingly, Subscriber Identification Module (SIM) based approach is suggested since it is more applicable for the case of Ethiopia. The newly designed framework is found to be better than the original model in terms of security (confidentiality and integrity). The study further investigated usability of the existing and newly proposed models’ user interface with a sample of 37 experts from ethio telecom and Commercial Bank of Ethiopia. Results from the experiment indicate that the current scheme took statistically significant time to complete a given task than the proposed model. The current model is preferred by participants on some of usability parameters such as learnability, satisfaction and ease of use. Overall, 94.6% of the experts involved on the experiment preferred the proposed model due to its security (better authentication using One Time PIN (OTP) code). | en_US |
