The Design And Implementation Of The Bank Customer’s Information Management System Based On DES Encryption Algorithm

Bank is the key of safety protection unit, each person’ s circulation economy, financial reserves or livelihood development is an important part and bank, computer applications to infiltrate each perso n’s social life, the bank of the relationship to th e development of the personal life level an d platform without the involvem ent of computer application technology, and play a role in people daily in the bank transaction records are reach ed tens of m illions of in formation, this inform ation includes text, data, im age and so on som e unstructured data, how to m anage these information and explor e the hidd en treasure will becom e the Banks the winning a magic weapon. As China joined the worl d trade organization, each big bank competition is particularly fierce, so better trading patterns mining customers, trading content, and storage habit will become particularly important. This thesis is based on the current social needs and better create va lue for the bank this major requirements, design and implementation of customer management systems.Fierce competition between Banks, m ake customer information management system is particularly important, and at the same time is another major problem for violence between Banks and steal infor mation between each other, on the one hand may be traffickers use of custom er information, to the custom er caused a lot of unnecessary harm and even personal property, on the other hand for Banks, the loss of customer information will lead to both the Banks themselves and brought in the sense of loss to the customer, so the protection of information and reliance will rise greatly, therefore, the security problem became the Banks and the users of another one of the main problems, and the im portant weapon in the inform ation security has becom e obviously encryption technology, and plays a more and more im portant role. DES(Data Encryption Standard) Encryption algor ithm, has gone through a lot in the field of long.term test. Practice has proved that the DES encryption algorithm in the field is of use value and research significance.In this paper, in addition to the bank customer management system on the design and implementation, also introduces the related knowledge and principle of DES encryption algorithm, the importance of DES encryption algorithm process. On the whole, this paper im plements both for the implementation of bank custom er management system, and realized on the rese arch of the algorithm, the algorithm has a more profound understanding.
