This work is based on a research of a concept of building a menu with user access control to its elements. The menu building concept is researched in scope of an object-oriented environment, with a particular reference to an Oracle database user access. In a research of the menu building in an object-oriented environment, java programming language is used. In this environment, new classes for building a menu with an access control are implemented. Since the access control is based on data regarding users and their privileges already available in a database, Oracle database connection via java Database Connectivity - JDBC is used.

Currently, developing a multithreading Application Programming Interface (api) for special use is extensive. Defects that are the most concern are deadlocks since the deadlock causes the application developed on top of the api stops working. The deadlock detection algorithm has been developed widely. We present another deadlock detection algorithm using the concept of static analysis. The algorithm detects potential deadlocks in the source code of the multithreading api. Finally, it reports deadlock sites. The result assists the developer to be aware of code synchronization that potentially encounters deadlocks. Moreover, it is related information to find the root cause of the deadlock in the future.

Although the Android system has been continuously hardened against side-channel attacks, there are still plenty of apis available that can be exploited. However, most side-channel analyses in the literature consider specifically chosen apis (or resources) in the Android framework, after a manual analysis of apis for possible information leaks has been performed. Such a manual analysis is a tedious, time consuming, and error-prone task, meaning that information leaks tend to be overlooked. To overcome this tedious task, we introduce SCANDROID, a framework that automatically profiles the java-based Android api for possible information leaks. Events of interest, such as website launches, Google Maps queries, or application starts, are triggered automatically, and while these events are being triggered, the java based Android api is analyzed for possible information leaks that allow inferring these events later on. To assess the Android api for information leaks, SCANDROID relies on dynamic time warping. By applying SCANDROID on Android 8 (Android Oreo), we identified several Android apis that allow inferring website launches, Google Maps queries, and application starts. The triggered events are by no means exhaustive but have been chosen to demonstrate the broad applicability of SCANDROID. Among the automatically identified information leaks are, for example, the java. io. File api, the android. os. storage. StorageManager api, and several methods within the android. *** api. Thereby, we identify the first side-channel leaks in the Android api on Android 8 (Android Oreo).

Building an effective methodology to detect characters from images with less error rate is the great task. Our aim is to furnish such an algorithm that will be able to generate error free recognition of text from the given input image which will help in document digitizing and prevention to the hand written text recognition. OCR has been in the intensive research topic for more than 4 decades, it is probably the most time consuming and labor intensive work of inputting the data through keyboard. This paper discuss about mechanical or electronic conversion of scanned images, text which contain graphics, image captured by camera, scanned images and the recognition of images where characters may be broken or smeared. The optical character recognition is the desktop based application developed using java IDE and mysql as a database. We have gain 91.82% accuracy when applied on different data sets, in pre-processing we used different techniques to remove noise from the image in post processing we used dictionary for the characters which are not recognized during classification, in classification we have used the back propagation algorithm for the training of neural network, feature extraction has been performed by template matching and hamming distance. All the algorithms have been developed in java technology.

Mobile applications are being implemented in varieties of areas including mobile commerce, purchase of services and products using mobile devices, gaming, banking, information services etc. Obafemi Awolowo University is a large academic community that can benefit from a mobile information service centre. There is a large population of students who can satisfy a great deal of their information needs. Existing modes of information delivery are inefficient and in most cases not timely. There is therefore a need for the provisioning of a suitable software application framework that can meet this critical need. This paper presents a suitable software system that can deliver information services with mobile functionality to the content subscriber (students in this case). Mobile devices are prevalent amongst students and teachers, which provides the motivation for the application of mobile technologies in learning environment. The mobility provided was achieved using SMS over GSM Network with the hardware implemented on a GSM Nokia phone acting as a modem. Object-Oriented Analysis and Design (OOAD) approach with the Unified Modelling Language (UML) was employed to document the software component of the application. This system was then implemented in java programming language. The software developed include;integrated subscription, payment and billing, user profile management, efficient mobile architecture, and ease of content publishing, all loosely coupled, to allow for further extension to the service architecture.
