To protect the multimedia data, a mixed encryption algorithm together with two advanced cryptography-DES ( Data Encryption Standard ) and Blowfish based on fingerprint watermark is studied.
In the system a new method is presented for improving the information transmission security, which integrates the DS1991 ( MultiKey iButton ) key technology and simple DES ( Data Encryption Standard ) algorithm to encrypt important data.
In this article, it was adopt symmetric encryption DES ( data encryption standard, DES ) algorithm, To achieve higher security, we have developed triple DES algorithm, 3-DES is an upgrading of DES.
Methods of database encryption and its characteristics are firstly discussed. Then the method of encryption algorithm like DES ( Data Encryption Standard ) & sub-key database encryption algorithm is introduced in detail;
AES ( Advanced Encryption Standard ) is the newest standard of National Institute of Standards and Technology ( NIST ) for data encryption and is used to replace the DES ( Data Encryption Standard ), the encrypt security level of which is reduced day by day.
