CYBER EYE

ABSTRACT

The basic idea behind this project is to computerize the communication between

the reception section and the internal office. Security takes an important role in

almost all of the organizations. One portion of the security includes recording

information about the visitor, avoiding allowing of needless visitors etc. Cyber

Eye provides an efficient way of implementing the above security system.

Using this system, it is possible to send the information about the visitors to the

higher authority of the organization. The highlight of this project is, not only

sending a textual message, it is possible to send the snapshot of the visitor as an

image.

EXISTING SYSTEM:

The existing traditional system provides only a person-to-person

communication. The person who receives the visitor obtain information such as

name, whom to meet, coming from where and it is informed to the higher

authority. Based on the decision made by the higher authority the visitor is

allowed or not allowed. This kind of communication is still used by lower level

organizations.

PROPOSED SYSTEM:

Higher-level organizations use the intercom facility to communicate with

other portions of the organization. This system provides immediate passing and

receiving of information. In both the above cases, it is possible to pass and

record only the name and some additional information about the persons in a

text format. In addition, any bogus information given by the visitor cannot be

used for further future reference.

1. INTRODUCTION

1.1 PROBLEM

The existing traditional system provides only a person-to-person

communication. The person who receives the visitor obtain information such as

name, whom to meet, coming from where and it is informed to the higher

authority. Based on the decision made by the higher authority the visitor is

allowed or not allowed. This kind of communication is still used by lower level

organizations.

Higher-level organizations use the intercom facility to communicate with

other portions of the organization. This system provides immediate passing and

receiving of information. In both the above cases, it is possible to pass and

record only the name and some additional information about the persons in a

text format. In addition, any bogus information given by the visitor cannot be

used for further future reference.

1.2 SOFTWARE TOOL

We have used the following software tools in developing our project,

Microsoft Visual Basic.Net

Microsoft SQL Server

Microsoft Visual Basic.Net

With its release for the .NET platform, the Visual Basic language has

undergone dramatic changes.

For example:

• The language itself is now fully object-oriented.

• Applications and components written in Visual Basic .NET have full

access to the .NET Framework, an extensive class library that provides

system and application services.

• All applications developed using Visual Basic .NET run within a

managed runtime environment, the .NET common language runtime.

Visual Basic .NET is the next generation of Visual Basic, but it is also a

significant departure from previous generations. Experienced Visual Basic 6

developers will feel comfortable with Visual Basic .NET code and will

recognize most of its constructs. However, Microsoft has made some changes to

make Visual Basic .NET a better language and an equal player in the .NET

world. These include such additions as a Class keyword for defining classes and

an Inherits keyword for object inheritance, among others. Visual Basic 6 code

can't be compiled by the Visual Basic .NET compiler without significant

modification. The good news is that Microsoft has provided a migration tool to

handle the task.

Microsoft SQL server

Microsoft SQL server lets you quickly build powerful and reliable

database applications. SQL server 7.0 highly scalable, fully relational, high

performance, multi-user database server. That can be used by enterprise of any

size to manage large amount of data for client\server applications.

The major new and improved features of SQL server 7.0 include the

multi-user support Multi platform support, added memory support, scalability,

integration with MMC, Microsoft Management console and improved multiple

server management. Parallel database backup and restore. Data replication, Data

warehousing distributed queries, distributed transactions, Dynamic cocking

Internet Access, Integrated windows security, Mail integration Microsoft

English Query, ODBC Support.

SQL Server management is accomplished through a set of component

applications. SQL Server introduces a number of new and improved

management tools that are SQL Server Enterprise management, profiles, and

Query Analyzer service manager wizards.

2. PROBLEM STATEMENT

Cyber Eye can be used an alternate for the existing system. It stores the

snapshot of the visitor as an image file, along with the textual information. So, it

can be used for future reference. Based on the organization storing of

information can be customized so that information can be periodically deleted.

Cyber Eye can be established and worked only in a network. It needs a

minimum of two systems that is connected through network. One system is

installed in the reception, along with Camera as an additional device. The

snapshot of the visitor is taken through the Web Camera and it is send to

another system which is usually kept on the table of the higher authority, along

with additional information about the visitor such as name, coming from where

etc. The higher authority then takes decision as per his/her willing, whether to

allow the visitor or not. The receptionist allows or not allows the person based

on the decision taken by the higher authority.

It is not only a security system, which passes information to the higher

authority. It also stores the information about the visitor for future reference.

This is a generalized project so that it can be used in any organization like

factories, offices and colleges etc.

3. METHODOLOGY

We have technology concepts to implement this project. We use crystal

reports to create reports retrieving it from the database. The inheritance

concepts for reusing the invoked methods are been implemented. Other than this

various object oriented concepts are also included. Several modules are been

developed for doing these functionalities as explained below Some of the

database storing and retrieving concepts are also included in the project

The query is put to the database and the intelligent search gives the

response perfectly to the user. The person who queries the database selects the

appropriate response and delivers to each customer.

Incremental model is the software development technique used for the

development of this project. At initial stages of the project a sample model with

the basic and primary functions was developed. Then the additional

functionalities were added and gradually the application was built. The model

was evolved stage by stage and based on the facts and view gathered from the

reviews in every incremental stage of the project. This method was adopted due

to its greater flexibility for managing dynamicity involved with the application

deployment. And this is the main objective that our methodology is all about.

4. PROBLEM DESCRIPTION

The Project entitled “Cyber Eye” has eight modules. They are

1. Login

2. User Manager

3. Dispatcher

4. Receiver

5. Visitor Information

6. User List

7. Send Message

Login

Since the system has been developed as a multi user one, only authorized

users can logon to the system. Existing users enter username and password, and

click on Login button. After verifying the information with user info table any

one of the following will occur.

If the username is “Cymin” then the Dispatcher screen must be

opened. Also the Visitor Information screen must be opened.

If the username is other than “Cyber eye” then Receiver screen

must be opened.

When a user has logged in, then his/her information such as

username, system name, login time etc must be added as a new

record in Log Details table.

In order to create new users Sign Up button must be clicked. Only

“Cymin” user can able to create new users. When clicking on Sign Up button,

after checking whether it is “Cymin” user and its password, User Manager

Screen must be opened.

9

Note that, the “Cymin” user must already exist in the table. Other users

can be created by “Cymin” user.

User Manager

Previously mentioned, only “Cymin” user can able to create new users.

By supplying the user name “Cymin” and its password the user has to click on

Sign Up button. The User Manager screen must be opened. It contains the

following process

New User Creation

Username must be unique

After supplying the other details, Submit button must be clicked.

The details must be stored in User Info table.

Also for the user, xxx Visitor Info and xxx Current Visitor table must

be created. For e.g. if the username is Rao then Rao Visitor Info and

Rao Current Visitor table must be created.

User Modification

User name must be selected from the combo box which is already

built using username field from the User Info table.

After modifying values Modify button must be clicked.

Values must be updated in User Info table.

User Deletion

User name must be selected from the combo box which is already

built using User Name field from the User Info table.

When clicking on Delete button, after confirmation from the user the

selected user details must be deleted from the table User Info and also

the related tables must be deleted.

Dispatcher

10

Used to take a snap shot image of the visitor and to send it to the

corresponding person. Used by the reception/security section. It contains the

following process

On Clicking Snap button it must receive the image of the visitor

through camera.

Other information must be filled.

From whom to meet combo box the person to meet is selected. This

combo box is already built with contents from Log Details table.

When clicking on Send button the following must be done:

1. A filename must be generated automatically to store the image. The image

file must be stored in a separate location and the path of the image must be

stored in table.

2. The information must be stored in the tables xxx Visitor Info, xxx Current

Visitor and Visitor Info. xxx stands for the name, selected from whom to

meet combo box.

3. A notification must be sent to the person whom the visitor wants to meet.

4. If the table xxx Current Visitor already has a record, then it means that the

particular used didn’t receive the previously sent information. In this case the

information must not be sent.

5. Also if the person is busy the information should not be send. It is already

identified when the person click on Disable button, from the Receiver

screen.

Clicking on Hide button must hide the image.

Clicking on Clear button must clear the contents of all the controls.

Clicking on New button must clear the contents and place the current

date and time on the date and in time boxes respectively.

Clicking on Send Message button opens the Send Message screen,

which is used to send message to the other users on the network.

11

Clicking on User List shows list of user information, so that

reception/security section operator can able to know the user name of

all the persons in the organization.

On clicking Logout button the Dispatcher screen must be closed. Also

after confirmation from the user the Visitor Info table contents must

be deleted.

xxx Visitor Info table is a permanent one, and used for future

reference.

xxx Current Visitor table is used to temporarily store the information.

This is used by the Receiver screen.

Visitor Info holds the visitor information only for the current day.

That is on the end of the day Visitor Info table contents must be

deleted.

Receiver

Used by the client systems, to receive information of the visitors from the

reception/security section. It contains the following process

When receiving notification from the reception/security section, the user

has to click on Receive button.

When clicking on Receive button the following must be done:

1. Information must be obtained from the xxx Current Visitor table

and placed in the specified controls. Here xxx stands for the current

Receiver screen user name.

2. Also the image file path must be obtained and the image must be

read and placed in the specific control.

3. The record from the table xxx Current Visitor must be deleted.

After typing the response, the user has to click Notify button. It must

update the necessary fields in the xxx Visitor Info and Visitor Info table.

Clicking on Hide button must hide the image.

12

Clicking on Clear button must clear the contents of all the controls.

Clicking on Logout closes the Receiver screen. When closing it must

update the Logout Time field in Log Details table.

Clicking on Waiting List button shows list of visitor waiting for meet that

person.

Clicking on Send Message button opens the Send Message screen, which

is used to send message to the reception/security section or other users on

the network.

Clicking on Disable disables receiving of visitor information from the

reception/security section, indicating that the person was busy. Also the

button caption changed to enable. When clicking on Enable it enables

receiving of visitor information and caption must be changed to disable.

Visitor Information

Used by the reception/security section, to view the visitor information. It

must display the information such as visitor name, whom to meet, in time etc

from the table Visitor Info. It contains the following process

When departure of a visitor the out time and visited (Yes/No) controls

must be filled.

Then when clicking on Update button the tables Visitor Info and xxx

Visitor Info must be updated with the values out time and visited.

Clicking on Refresh refreshes the display.

User List

Used to list of the user information. This screen is activated from the

Dispatcher screen. It contains the following process

13

When opened shows the information of users. Information is taken

from the table User Info.

Send Message

Used to send messages between the persons on the network. It contains

the following process

The recipient must be selected from the combo box whom to send. It

is already built using the table Log Details.

Message must be typed and when clicking on Send it must be send to

the particular user who is in online.

6. SYSTEM ANALYSIS AND DESIGN

6.1 DATA COLLECTION

14

We had collected various types of data that is to be used with in the

project. First we had collected the statistical data about the software to develop

the project, so that the methods and concepts involved matches with the project.

Next we had done the actual data collection for updating in the database and to

build efficient database. Data from all sort of computer related topics are been

obtained from various books and websites. We had developed our software for a

generalized purpose.

6.3 FEASIBILITY STUDY

16

Feasibility Study is conducted to sea if the proposed system is a feasible one

with all respects. Feasibility Study is lot of the system proposal according to its

workability impact of the organization, ability to meet uses need and effective use of

resources. There are three main aspects in the feasibility study.

Technical Feasibility:

Technical feasibility centers on the existing system and to the

extent it can support the proposed system. The design of the cyber eye is in such

a way that it can be easily managed. If budget is not a serious constraint then the

project is judged technically feasible.

The system is assigned to fit the available software the hard ware. Visual

Basic.NET a Graphical User Interface meets the software Requirement.

VB.NET has more controls which facilitates the creation of user-friendly

screens. VB.NET also feasible and can meet any expansion or revision of this

system in future.

Operational Feasibility:

An operationally feasible system is one that will be used

effectively after it has been developed. If users have difficulty with a new

system, it will not produce the expected benefits. The proposed system is found

to be operationally feasible because of the following reasons. It needs only one

person in the reception section. There is no difficulty in using the front end

which has been developed. Even the users who don’t have any knowledge in

computers the user friendliness provides them convenience and case. The

system is designed, in such a way that not only the person currently handling

this work can operate the system but a person who is new to the system with

case. Hence this system is found to be operationally feasible.

Economic Feasibility:

17

In economic feasibility cost/benefit analysis is done. Here we

determine the benefits and time savings that are expected from the system and

compare them with cost. The proposed system is economically feasible. Since

the cost of the system is only the implementation cost of the system. There is no

need spend any monthly there after. The web cam needed is available at the

least possible cost at the same time reliable. Since benefits outweigh the cost. It

is economically feasible.

6.5 DATA BASE DESIGN

18

A database is a set of related data. It provides flexibility in the storage

and retrieval of data and production of information while designing a database

there are many things to be taken care of. Data shouldn’t be redundant and it

shouldn’t be in consistent. After storing data in the database there should be any

difficulty in accessing data. The data should be secured. Above all the database

should be normalized.

NORMALIZATION:

Normalization is a process of simplifying the relationship between

data elements in a record. Through normalization a collection of the data in a

record structure is replaced by successive record structures that are simple and

more predictable and therefore move manageable.

NEED FOR NORMALIZATION:

To structure the data so that any pertinent relationships

between entities can be represented.

To permit simple retrieval of data in response to query and

report requests.

To simplify the maintenance of the data through updates,

insertions and deletions.

NORMALIZATION IN THE PROPOSED SYSTEM:

In the proposed system, normalization is achieved. The system is

normalized to first and second Normal form.

First Normal Form:

19

First normal form is achieved by removing all repeating groups. So

that a record of fixed length. The repeating group is removed and a separate file

or relation containing the repeating group is created. The original records and

the new records are interrelated by a common data item. In the proposed system

first normal form is achieved.

Second Normal Form:

Second normal form is achieved when a record is in first normal

form and each item in the record is fully dependent on the primary record key

for identification. In other words function dependency should be achieved i.e. a

data item is functionally dependent it‘s value is uniquely associated with a

specific data item. In a proposed system the data items in the relation details are

dependent on the visitor-id, which is primary key. Thus, normalization is

achieved in the proposed system. It contains the following tables

Table Design

20

Column name Data Type Length Allow Nulls

Username varchar 20 SystemName varchar 200 LoginDate varchar 15 LoginTime varchar 15 Logout Time varchar 15

Table 6.5.1 Log Details

Column Name Data Type Length Allow NullVisitorID Numeric 5 VisitorName varchar 50 Address varchar 200 Company varchar 50 Designation varchar 50 Purpose varchar 100 Remarks varchar 250 VisitorImage Image 16

Table 6.5.2 RameshCurrentVisitor

Column name Data Type Length Allow NullUserName varchar 20 Password varchar 20 FullName varchar 50 Department varchar 20 Designation varchar 50 Remarks varchar 200

Table 6.5.3 User Info

21

Column name Data Type Length Allow NullsVisitorID Numeric 9 VisitorName Varchar 50 Address Varchar 200 ContactNo Varchar 20 Company Varchar 50 Designation Varchar 50 Purpose Varchar 100 InDate Datetime 8 InTime Varchar 15 OutTime Varchar 15 Remarks Varchar 100 WhomToMeet Varchar 20 Response Varchar 100 Visited Varchar 1 VisitorImage Image 16

Table 6.5.4 Visitor Info

8. CONCLUSION AND FUTURE ENHANCEMENT

22

7.1 CONCLUSION

Thus the communication between the receptionist and the internal

officers were computerized through Cyber Eye Software. The visitor Records

are stored in the Database for future reference. The Crystal reports are generated

based on the Visitor Information.

7.2 FUTURE ENHANCEMENT

In Future we develop this software to store the conversation between the

visitor and the internal officer as a video streams and also we may change the

communication between the reception section and the internal office as a

wireless communication.
