Image Steganography using Password Based Encryption Technique to secure e-Banking Data

摘要

e-banking is the essential financial transaction system via online. It is required to keep the financial data intact and secure from the intruder. In this paper we have applied password based encryption technique on image Steganography to secure e-Banking data. Customer should require registration through personal data along with user_Id and password to access one's account and it requires eight characters for password preparation. Image is segmented into eight non overlapping blocks for embedding secret information. Eight characters are required to form block key for eight consecutive blocks. Message bits are encrypted with block key using XOR method and embedded eight bit per pixel into RGB cover image. On the receiver side images are authenticated by password and retrieve message using XOR technique.
