As the modern world going on-line for all businesses, so we need to transact with various organisation all over the world using different modes of payment obtained through various Financial Institutions.
Usually in banks manual cheques are provided. but in this paper we made e-cheques. In this e-cheque we apply three algorithms for security purpose. These three algoriths are: DSA, DES, AUDIO STEGANOGRAPHY TECHNIQUE
Using DSA for the integrity of data and identity of the signatory, DES for encryption and the last is to hide data behind the audio files(.WAVE).
The e-cheques has many advantages over manual cheques.e-checks reduce the loads over banks. A cryptography method is used for encryption-decryption for security purpose but it has some demerits over security like poor key management, non-repudiation. So in this case using steganography for higher security. Digital steganography cannot hide large amount of data that's why audio steganography is more preferable.
