Data Security by Location Based Encryption for Banking Application

Abstract

The focus of this paper is to build an Android platform based mobile application to provide secure access
to critical and confidential information in banks using location based cryptography. With compare to existing banking
application which are location-independent, the paper is proposing banking application which is location dependent
means only at specified location Cipher-text from cryptography could get decrypted. Any other attempt to decrypt data
at another location, the process cannot decrypt it and cannot identify information about the plaintext. This approach
is important in real time applications like military, Cinema Theater etc. The proposed application is providing
flexibility to customer in such a way that he/ she will access his/her account from any location for completing their
tasks. However, most of the info encoding technology is location-independent. Associate degree encrypted knowledge
is decrypted anyplace. The encoding technology cannot prohibit the situation of information cryptography. So as to
satisfy the demand of mobile users within the future, a location-dependent approach, known as location-dependent
encryption formula (LDEA), is planned during this paper. A target latitude/longitude coordinate is decided first off.
The coordinate is incorporated with a random key for encryption. The receiver will solely decode the cipher text once
the coordinate inheritable from GPS receiver is matched with the target coordinate. However, current GPS receiver is
quality and inconsistent. The situation of a mobile user is troublesome to precisely match with the target coordinate. A
toleration distance (TD) is additionally designed in LDEA to extend its usefulness. The protection analysis shows that
the chance to interrupt LDEA is sort of not possible since the length of the random secret is adjustable. An image is
additionally enforced for experimental study. The results show that the cipher text will solely be decrypted beneath the
restriction of TD. It illustrates that LDEA is effective and sensible for knowledge transmission in mobile setting.
