Cancellable biometric using matrix approaches

PhD ThesisCancellable biometrics endeavour to hide the appearance of a biometric image into a transformed template which prevents the outsider from recognising whom the biometric belongs to. Current research into cancellable biometric methodologies concentrates on the details of biometric traits. This approach has a drawback which cannot possibly be implemented with other biometric technology. To address this problem, this thesis contributes to development of a novel concept for the feature transformation of biometric technology, especially for fingerprints, by utilizing several matrix operations to provide an alternative algorithm in order to produce multi-implementation of the cancellable system. The matrix operations generate the feature element of the input fingerprint image in an irrevocable form of output fingerprint template by ignoring the type of biometric traits unique to fingerprints; thus, the cancellable algorithm can be implemented in different biometrics technologies. The implementation offers a new concept in generating a cancellable template by considering a sequential procedure for the fingerprint processing, in order to allow the authentication process to succeed in authenticating an enquired input. For example, a region of interest (RoI) step is required to provide a square form input to support the system working in a matrix domain. Meanwhile, the input fingerprints are mostly in rectangular form. This thesis contributes a new approach to selecting a certain area of a fingerprint by utilizing the density of ridge frequency and orientation. The implementation of these two enhancement steps reduces the excision process of this significant region of the fingerprint by avoiding the involvement of a non-feature area. Meanwhile, to avoid obtaining an un classified fingerprint, this thesis offers a new approach to the fingerprint image classification process entailing three requirements in classifying the fingerprint: the core point and its number, ridge frequency, and ridge direction; whilst the tented arch (TA) is only an additional requirement. The proposed idea increases both the percentage accuracy in classifying fingerprints and time consuming of the system. For Example, the accuracy of the fingerprint classification improves from less than 41 per cent of the fingerprint to 86.48 per cent in average for all of databases.Directorate General of Higher Education of the Ministry of Education and Culture of the Republic of Indonesi

CORE-POINT, RIDGE-FREQUENCY, AND RIDGE-ORIENTATION DENSITY ROLES IN SELECTING REGION OF INTEREST OF FINGERPRINT

ABSTRACT: In fingerprint recognition technology, ridge-frequency and -orientation step are utilized to identify trait pattern of ridge/valley features of the fingerprint by separating foreground and background of the fingerprint image and specifying the directional pattern of the ridges and valleys. The ability to determine the patterns help us as well to select a particular area to be utilized forth. Meanwhile, core-point is needed as a reference point in region of interest (RoI) cropping process. For example, if a desired region is a squareform area, core-point can be as a central of the RoI. Thus, we just need to lay down two diagonal side of the selecting area. In conclusion, it is obvious that the superiority of these three steps can be exploited in RoI step

Sistem Tracking Cahaya Matahari pada Photovoltaic

Umumnya solar cell yang dipasang hanya menghadap satu arah tertentu saja. Gerak semu harian matahari menyebabkan perubahan posisi matahari dari timur ke barat setiap harinya. Perubahan posisi matahari tersebut membuat modul solar cell tidak selalu mendapatkan intensitas cahaya matahari yang maksimal sepanjang hari. Salah satu cara yang dapat dilakukan supaya solar cell mendapatkan intensitas cahaya matahari yang maksimal sepanjang hari adalah dengan menempatkan modul solar cell tegak lurus mengikuti cahaya matahari. Hal tersebut yang melatarbelakangi pembuatan alat tracking cahaya matahari menggunakan komponen Light Dependent Resistor (LDR) sebagai sensor dan motor linear aktuator parabola sebagai penggerak posisi modul solar cell. Cahaya matahari yang mengenai sensor LDR membuat resistansinya berubah sehingga mempengaruhi nilai tegangan yang akan diinformasikan ke analog input mikrokontroller. Mikrokontroller mengolah informasi yang diterima dari sensor LDR dan memberi perintah untuk menggerakkan linear aktuator yang mana akan menggerakkan posisi permukaan modul solar cell dengan dua arah yaitu mengikuti orientasi gerak semu harian matahari dari arah timur ke arah barat. Pada arah timur dan barat masing-masing terdapat sebuah limit switch. Ketika malam hari  modul solar cell ini akan kembali bergerak menghadap ke arah Timur dan akan berhenti ketika limit switch Timur aktif. Alat tracking cahaya matahari ini telah dilakukan uji coba. Alat ini telah dapat  mengikuti pergerakan matahari dari timur ke barat dengan daya keluaran solar cell dari 8,71 watt mampu ditingkatkan menjadi 12,46 watt dengan konsumsi daya motor sebesar 2,08 watt.Umumnya solar cell yang dipasang hanya menghadap satu arah tertentu saja.

Alternative approach in generating cancellable fingerprint by using matrices operations

A cancellable biometric system aims to revote a biometric feature of an authorized person when his biometric information is misused by improper. In this system, an established biometric image is transformed to a different feature to distinguish it from the original one. Moreover, this revocable system can regenerate a new transformed cancellable biometric feature if the previous transformed feature is known by someone. These basic concepts are similar with the idea of inverse matrix and elementary row operation in matrices domain. Biometric image as a digital image definitely can be processed in matrices domain. It means that the image is able to be imposed by matrices operations such as inverse matrix operation, elementary row operation, and Kronecker product operation. In matrix, these operations are used for several objectives whether inverting matrix elements, changing rows or columns, or enlarging size of the matrix. On the other hand, the combination of these operations even can produce a non-inversed matrix
