SMART SECURE

Secures your mobile device and personal data in the event of loss or theft by allowing you to

locate/track your device, helps prevent device misuse, and remotely locks your device and wipes

your data. It enables you to back up and restore your data from the device or via an easy-to-use web

portal..Android is an open source software stack operated in a heterogenic mobile environment.

Thus, hackers can more easily access, manipulate, and exploit the operating system code very easily.

As a counter suggestive remote management capabilities along with additional security solutions can

improve security substantially. If an attacker steals a device, users could protect information

remotely by turning on a defensive mechanism remotely through a SMS. The intended proposals

are:-

Data encryption: Encrypting data is an excellent way to counter private data exposure. Because

only the owner knows the key for deciphering data, the information is secure. Encrypting sensitive

data can also be handled by core applications such as SMS messaging and that will require

developing applications.

Context-aware access control: By employing context-aware access control (CAAC), users can

1. INTRODUCTION

1.1. GENERAL INTRODUCTION

SMART SECURE is the complete mobile security service that protects data on your

phone, ensures privacy in the event of theft and enhances the possibility of recovering yourphone. Android is an open source software stack operated in a heterogenic mobile

environment. Thus, hackers can more easily access, manipulate, and exploit the operating

system code very easily. As a counter suggestive remote management capabilities along with

additional security solutions can improve security substantially. If an attacker steals a device,

users could protect information remotely by turning on a defensive mechanism remotelythrough a SMS and web. The application is developed in ANDROID. The database is created

using SQLite.

1.2. STATEMENT OF PROBLEM

A statement of problem is a clear description of the issue(s), it includes a vision, issue

statement, and method used to solve the problem. The purpose of this project is to develop an

application provides user friendly interface. The existing system provides an unrealistic interface and

2. SYSTEM ANALYSIS

System analysis is a general term that refers to an orderly, structured process for identifying

and solving problems. Before designing a computer system, it is important that the nature of business

and the way it currently operates are clearly understood. The detailed examination will then provide

the design team with the specific data they requires in order to ensure that the clients requirements arefully met.

Analysis involved a detailed study of the current system, leading to specifications of a new

system. Analysis is a detailed study of various operations performed by a system and their

relationships within and outside the system. During analysis, data are collected on the available files,

decision points and transactions handled by the present system. Interviews, on-site observation andquestionnaire are the tools used for system analysis. Using the following steps it becomes easy to

draw the exact boundary of the new system under consideration:

Keeping in view the problems and new requirements Workout the pros and cons including new areas of the system

All procedures, requirements must be analyzed and documented in the form of detailed data

flow diagrams (DFDs), data dictionary, logical data structures and miniature specifications. System

2.1. EXISTING SYSTEM

In the existing system, it is difficult to trace the lost phone. The only way to track phone is by

the IMEI number. It is done by the help of security authorities and service providers. Also there is no

security for the private datas in phone like contact numbers, credit card password,personal datas etc.

It can be easily traced out by phone thief, also there is no way to store any backup of our private datas

in phone. Similarly there are no functions available for avoiding the unwanted calls/sms from

particular numbers.

2.2. DRABACK OF EXISTING SYSTEM

There exist many disadvantages in the existing system. Some of the main problems with the

conventional system are:

Difficult to trace lost phone No security for private datas in phone No way to backup data No way to avoid unwanted calls/sms

2.3. PROPOSED SYSTEM AND ITS FEATURESThe scope of this application is to provide user friendly working environment and more

Finding out whether a new system is required or not. Determine the potentials and drawbacks of the existing system Identification of user requirements and the benefits expected by the user from the

resulting system.

Finding out the various alternatives available. Knowing what should be incorporated in the new system. Define the ingredients and objectives involved in the project.

Feasibility study is conducted to test whether the system is beneficial to the organization. The

feasibility study analyses potential solutions against a set of requirements, evaluate their ability to

meet these objectives, describe a recommended solution, and offer a justification for the selection.

Considering the technical aspects of feasibility, the proposed system is very useful and

helpful in finding solution as soon as they come across a problem encountered. It acts as network

trouble shooting tool. It maintains computer traffics and is capable of finding whether a system is

down or not, if it is working properly or not etc. Thus it is technically feasible.

This software is user friendly. There is no need that should be technically skilled to use this


11/35


2.4.1. Technical Feasibility

The main objective of feasibility study is to test the technical, social and economic feasibility

of developing a system. Investing the existing system in the area under investigation and generating

ideas about the new system does this. Feasibility study has been done to gather required information.

Training, experience and commonsense are required for collection of the information. Data was

gathered and checked for completeness and accuracy. Analyzing the data involved identification of

the components of the system and their inter relationship and identifying the strength and weakness of

the system.

The main points that are considered to prove that the project is technically feasible are:

The present technology is sufficient to develop the project. The proposed system provides adequate response to the user. The system can be expanded and developed. The project outputs given are reliable and it is easy to access.

2.4.2. Economic Feasibility


12/35


Proposed system is economically feasible because it uses available resources rather than

special additional resources. Software development cost is much less. In the proposed system the cost

of hardware and software for the class of application of web development is less.

2.4.3. Operational Feasibility

There is no difficulty in implementing the system. The proposed system is effective, user

friendly and functionally reliable that the user in the company will find the new system reducing their

hardship. The user of the system must be completely unaware of the internal working of the system so

that the users will not face any problem running the system. The system thus reduces the responsive

time of computer thereby, the system is found to be operationally feasible.

Design is the only way that can accurately translate customer registration into finished

software or system. Without software design, the risk of building an unstable system exists. System

design provides the procedural details necessary for implementing the system recommended in the

feasibility study.

3. SYSTEM DESIGN3.1 INRTRODUCTION

System design refers to the description of a new system based on the information that

collected during the analysis phase and the process by which it is developed. It is the most creative

and challenging phase of the system life cycle. The design of the system is essentially a blue print or a

plan for a solution for the system. The primary objective in this case is to design a system which

delivers the functions required by the client in efficient message passing within an organization. Detail

design focuses on refinement to the architectural representation that lead to detail algorithm data

structure and representation of software. System design is a creative art of inventing and developing

inputs, database, file, methods and procedures for processing to get a meaningful output that satisfy

the organization objectives. Software design is considered as the main part of software engineering

process and is applied regardless of the software process model that is used. The system design

includes the database design, the requirements specification for inputs, processing and outputs. During

the system design phase the designer must design how to produce an efficient and effective system.

There are two levels of system design.

L i l d i


14/35


3.1.1. REQUIREMENT OF SPECIFICATION

System analysts talk to a variety of persons to gather details about the data transfer and their

opinions of why things as they do and their ideas for challenging the process. These can be done

through detailed investigation and observation. As the details are collected, the analysts study the

requirements data to identify features the new system should have, including both the information the

system should produce and operational features such as processing controls, response times and input-

output methods.

Requirement specification simply means, Figuring out what to make before make it. It

determines what people need before start developing a product for them. Requirement definition is the

activity of translating the information gathered into a document that defines a set of requirements.

These should accurately reflect what customer wants. It is an abstract description of the services that

the system should provide and the constraints under which the system must operate. The notations

used for requirements definition should be based on natural language, forms and simple intuitive

diagrams. The requirements fall into two categories: functional and non functional

The requirements of specification of the proposed system are as follows

Faster response time Efficient processing

represents the entire software elements as a single bible with input and output indicated by incoming

and outgoing arrows respectively.

DFD illustrates how data is processed by a system in terms of inputs and outputs. It is a

picture of system processing and flow without excessive concern for details.

The DFD showing the top level of the system is called Context Diagram. It should be an

overview including basic inputs, processes and outputs. Then it is exploded in to more detailed lower

level diagram that shows additional features of the system.

The purpose of DFD is to provide a semantic bridge between users and system developers.

The diagrams are graphical, eliminating thousands of words, logical representations, modeling what

system does; hierarchical, showing system at any level of details; and Jargon less, allowing user

interaction and reviewing.

The goal of data flow diagramming is to have a commonly understood model of a system.

The diagram is the basis of structured system analysis. The Data flow diagram, also known as

Bubble Chart has the purpose of clarifying system requirements and identifying major

transformations that will become program in system design. The bubble represents the data

transformations and the lines represent data flows in the system.

DFD SYMBOLS

Process

A circle or a bubble represents a process that transforms incoming data flows into outgoing data

flows.

3.2. OUTPUT DESIGN

Output refers to the results and information that are generated by the system. Heredetermine information to be present, decide lat and select output medium, arrange

presentation of information in accepted format and decide how to distribute output to intend

recipients. Location characteristics and format of column headings and pagination are

specified.

Output design plays a major role in providing the user with required format. The

that should be given to the users according to the requirements. Efficient, intelligible output

design should improve the systems relationship with the user and help in decision making.

Since the reports are directing referred by the management for taking decisions and to draw

conclusions they must be designed with almost care and the details in the reports must be

simple, descriptive and clear to the user. So while designing output the following things are

to be considered.

Determine what information to present. Arrange the presentation of information in an acceptable format. Decide how to distribute the output to intend receipts Depending on the nature and future use of output required, they can be displayed on

the monitor for immediate need and for obtaining the hardcopy.

Efficient and intelligent output design should improve system relation with the user

and help in decision making that is, this makes system user friendly to be displayed or printed

as per the users choice. A quality output is one which meets the requirements of the end user

and which presents the information in a way which is clear, easy to read and visually

attractive. In order to decide on an appropriate method of presentation, and a suitable format,

Avoiding delay. Avoiding errors. Avoiding extra steps.

The input forms are designed, using GUI controls like Buttons, Images, Image

Buttons, Text Boxes, Spinners, and Last etc.

FEATURES OF INPUT DESIGN

The features of the input design are,

The input designing is done so as to have most efficient way forinteraction between the user and the system.

Measures have been taken to minimize user inputs. Extra steps are eliminated and process is made simple.

3.4. DATABASE DESIGN

A database is a collection of interrelated data stored with minimum redundancy to serve users

more quickly and efficiently. The general objective of a database is to make information access easy,

quick, inexpensive, integrated and shared by different applications and users. Database design is an

A primary key is an attribute (or combination of attributes) that uniquely identifies each

instance of an entity. A primary key cannot be null and the value assigned to a primary key should not

change over time. A primary key also needs to be efficient. For example, a primary key that is

associated with an INTEGER data type will be more efficient than one that is associated with a

CHAR data type.

A relationship is a logical link between two entities. A relationship represents a business rule

and can be expressed as a verb phrase.

The second type of relationship is the "many-to-many" relationship. In a "many-to-many"

relationship, many instances of one entity relate to many instances of the other entity. "Many-to-

many" relationships need to be resolved in order to avoid data redundancy. "Many-to-many"

relationships may be resolved by creating an intermediate entity known as a cross-reference (or

XREF) entity.

A "foreign key" exists when the primary key of a parent entity exists in a child entity. A

foreign key requires that values must be present in the parent entity before like values may be inserted

in the child entity. The concept of maintaining foreign keys is known as "

/res

This directory contains all the external resources (images, data files etc)

that are used by the android application. These external resources

(content) will be referenced in the android application.

This contains the following sub-folders

This folder also contains external resources used in the application like the /res folder. But the main

difference is that the resources are stored in raw format and can be read only programmatically.

4.3. SELECTION OF SOFTWARE

4.3.1. ANDROID

Android is a software stack for mobile devices that includes an operating system, middleware

and key applications. The Android SDK provides the tools and APIs necessary to begin developing

applications on the Android platform using the Java programming language.Android applications arewritten in the Java programming language. The Android SDK tools compile the codealong with

any data and resource filesinto anAndroid package, an archive file with an .apk suffix. All the code

in a single .apk file is considered to be one application and is the file that Android-powered devices

use to install the application.Application components are the essential building blocks of an Androidapplication. Each component is a different point through which the system can enter your application.

Not all components are actual entry points for the user and some depend on each other, but each one

exists as its own entity and plays a specific roleeach one is a unique building block that helps define

application's overall behavior.

Features

Application framework enabling reuse and replacement of components Dalvik virtual machine optimized for mobile devices Integrated browser based on the open source Web Kit engine

ANDROID ARCHITECTURE

The following diagram shows the major components of the Android operating system.

Each section is described in more detail below.


26/35


APPLICATION FRAMEWORK

By providing an open development platform, Android offers developers the ability to build

extremely rich and innovative applications. Developers are free to take advantage of the device

hardware, access location information, run background services, set alarms, add notifications to the

status bar, and much, much more.

Developers have full access to the same framework APIs used by the core applications. The

application architecture is designed to simplify the reuse of components; any application can publish

its capabilities and any other application may then make use of those capabilities (subject to security

constraints enforced by the framework). This same mechanism allows components to be replaced by

the user.

Underlying all applications is a set of services and systems, including:

A rich and extensible set of the views that can be used to build an application, including lists,grids, text boxes, buttons, and even an embeddable web browser

Content Providers that enable applications to access data from other applications (such asContacts), or to share their own data

A Resource Manager, providing access to non-code resources such as localized strings,graphics and layout files

Surface Manager - manages access to the display subsystem and seamlessly composites 2Dand 3D graphic layers from multiple applications

LibWebCore - a modern web browser engine which powers both the Android browser andan embeddable web view

SGL - the underlying 2D graphics engine 3D libraries - an implementation based on OpenGL ES 1.0 APIs; the libraries use either

hardware 3D acceleration (where available) or the included, highly optimized 3D software

rasterizer

FreeType - bitmap and vector font rendering SQLite - a powerful and lightweight relational database engine available to all applications

Android Runtime

Android includes a set of core libraries that provides most of the functionality available in the

core libraries of the Java programming language.

Every Android application runs in its own process, with its own instance of the Dalvik virtual

machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM

executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory

footprint. The VM is register-based, and runs classes compiled by a Java language compiler that have

If an activity has lost focus but is still visible (that is, a new non-full-sized or transparentactivity has focus on top of your activity), it ispaused. A paused activity is completely alive

(it maintains all state and member information and remains attached to the window manager),

but can be killed by the system in extreme low memory situations.

If an activity is completely obscured by another activity, it is stopped. It still retains all stateand member information, however, it is no longer visible to the user so its window is hidden

and it will often be killed by the system when memory is needed elsewhere.

If an activity is paused or stopped, the system can drop the activity from memory by eitherasking it to finish, or simply killing its process. When it is displayed again to the user, it must

be completely restarted and restored to its previous state.

The following diagram shows the important state paths of an Activity. The square rectangles represent

callback methods you can implement to perform operations when the Activity moves between states.

The colored ovals are major states the Activity can be in.

engine. SQLite is the most widely deployed SQL database engine in the world. The source code for

SQLite is in the public domain.

Features of SQLite

Application File Format. Rather than using fopen () to write XML or some proprietaryformat into disk files used by your application, use an SQLite database instead. To

avoid having to write and troubleshoot a parser, your data will be more easily

accessible and cross-platform and your updates will be transactional.

Database for Gadgets. SQLite is popular choice for the database engine in cellphones, PDAs, MP3 players, set-top boxes, and other electronic gadgets. SQLite has a

small code footprint, makes efficient use of memory, disk space, and disk bandwidth,

is highly reliable, and requires no maintenance from a Database Administrator.

Website Database. Because it requires no configuration and stores information inordinary disk files, SQLite is a popular choice as the database to back small to

medium-sized websites.

Stand-in for an Enterprise RDBMS. SQLite is often used as a surrogate for anenterprise RDBMS for demonstration purposes or for testing. SQLite is fast and

requires no setup, which takes a lot of the hassle out of testing and which makes
