CHAPTER 1

 INTRODUCTION

• BACKGROUND OF THE STUDY

Data security is a much  wider term than hardware or a software  feature. In  the entire  environment  of security,  it is necessary to  really insure privacy. Everyone in the group must be aware of the security goals and be conscientious in achieving them.  Permission to make  digital or  hard copies  of all or part  of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page. To copy otherwise, or republish,  to post  on servers or to redistribute to lists, requires prior specific permission and/or a fee

Usually security is lost due to slip  of security guard. It must be  even  maintained  during  the disposal  of  printouts  of previously encrypted data.

As data communication is becoming more pervasive, complex and the use of digital data is becoming much  more widespread,  data security  has  become  a  wider,  complex  and  more  important problem.  Encryption  can  be  an  important  tool  to  help  in improving data security. The critical concern  in designing  an encryption algorithm is the security  of  the  algorithm  against  undesirable  attacks.  In  this project, the performance of the leading secret key algorithms has been  compared on  different  platforms, using input  data files  of varying sizes and formats.

Data  security  algorithm  can  be  used  to  avoid  hacking  of confidential  data.  Without  knowledge  of  this  software  a  third person cannot access data.  The user should know the key used for algorithms. This algorithm is most useful in e-commerce, banking, and  online  transaction  processing  applications,  small  or  large-scale  industry,  medical  imaging,  telemedicine,  and  military communication and Banking etc.

• STATEMENT OF THE PROBLEM

The level of  attacks on data and information is on the increase posing great risk and danger .Now  a  day  information  security  becomes  complex  and  more  important  problem.  Encryption/decryption  can  be  an  important tool  to  help  in  improving  data  security.  The study, developed techniques for securing data to avoid hacking as well as providing  the user with some additional features such as as key for  integrity  and  validation  of  user.  In  this  technique  one  can secure  any  type  of  files  using  Fibonacci  series.

• OBJECTIVE OF THE STUDY

The main objective of the study is  data   encryption  using  fibonacci

Key questions include

1. What are  user’s  needs  and  how  does  Data  security  system meets them?

2:  What resources  are  available  for  a given security system? Is the Problem worth solving?

3:  What  is  the  likely  impact  of  the  security  system  on  the organization

• SIGNIFICANCE OF THE STUDY

The study proffers solution to handling the various attacks been experienced on data and informations.

• SCOPE OF THE STUDY

The study focuses on data   encryption  using  fibonacci

• LIMITATION OF THE STUDY

The study was confronted with logistics  and environmental constraint

• DEFINITION OF TERMS

FIBONACCI DEFINED

The  Fibonacci series  is  an emerging  area  in data  security. The

general  idea of  the Fibonacci  series encryption is  based on  the

application  of  the  generalized  Fibonacci  matrices,  the  Qp-

matrices, for encryption of the initial message, file encryption using fibonacci series project,
file encryption using fibonacci series, fibonacci numbers cryptography, data encryption through fibonacci sequence and unicode characters, fibonacci sequence cipher, fibonacci cipher, fibonacci cipher decoder,
