Abstract

The use of biometrics in various issues of data security, transactions, privacy has been widely used. Regarding security, surely the level of accuracy in one's self-recognition must be accurate. The palmprint is one of biometrics which has various unique characteristics. These characteristics include geometrical features such as length, width, and area of the palmprint, characteristics of main lines such as heart lines, headlines, and lifelines, tangled or weak lines, delta dot characteristics, and minus characteristics. Main lines and tangled lines, which are often referred to as line features, have several advantages over other biometric features, such as they can be obtained from low-resolution images, are difficult to duplicate, and are stable because they have experienced slight changes over a long period of time. This research introduces the method of Fermat's Spirals in the extraction of the features of the palmprint which are represented in the time series curve. Testing uses 450 palm images sourced from 50 people, each person taken 9 palmprint images where 5 images as a test image and 4 images as a reference image. The test is carried out based on the threshold value determined from the simulation results based on matching test images with reference images on the ROC graph. Based on the test results it can be concluded that the system shows high performance at a threshold value of 0.036 to get an FNMR value of 2.80%, FMR of 0.88% with an accuracy of 96.31% where the number of reference images to the test image affects the level of accuracy.

Abstract

Immigration Denpasar Office is one of the technical service units performing task and function Directorate General of Immigration. The immigration document publishing is one of the functions of the services implemented by Immigration Office Denpasar. Data security is the most important thing in document publishing activities for Indonesian. To find out the level of capability and conditions of IT governance in document publishing service for Indonesians, an IT governance analysis activity relates to service management in security and data accuracy is required. The results of the analysis are expected to produce recommendations to improve IT management related to security services, it can better support the organization’s bussiness objectives in the future. The study used capability model as a measuring tool to respondents answers related to questionnaires based on COBIT 5 domain DSS05 (Manage Security Service) framework consisting of 8 subprocesses, with total 43 statements. The result of the recapitulation show the level 3 with the status of Largely Achieved gained 83% indicates the process of information security services have done regulary implemented.
