In Mobile banking system the most important aspects are performing and data storage. These systems contain a small number of terminals be fond of ATMs, deposit machines and multimedia enquiry stations. Mobile banking system has customer based financial services and well built a strong foundation for customized, which employs a range of wireless channels of communication.An issue in security vary from one technology in the direction of other. While the time of its beginning, each type of crimes in technology the only target is the network financial services.
In mobile baking having two security zones they are Mobile operator & banking system zone, and mobile operator & user's zone. Wireless communication information security and virus attacks, hacking like information security interrelated to mobile banking are as exposed below:
Leakage, loss and distortion of information:
During the wireless networks transfer of information in mobile banking world. Digital data (0s and 1s) is used for implementation of wireless required radio network, complete modulation also convert them into radio signals. On the other hand, received radio signals are demodulated and transformed to digital data. To protect wireless data transmissions wireless technology provides extremely less number of tools. Banking transactions be confidential and may be leaked, lost or distorted throughout every day transaction devices.
Among unbalanced transmission channels and mobile devices, incomplete communications occur. Incomplete or collapse of data transfer moreover in weak wireless signal coverage region message send by the customer. From this, mobile devices guide to unfinished banking transactions in low electricity support.
The virus attacks are less in network banking while greater in mobile banking. Previous virus attacks are able to delete the data from the mobile phones. But now, a large amount can be affected into a wireless network. There are several factors which intensity the cause of virus. The wireless network in mobile phone, the fixed network terminals are infected by the sending virus is one of them.
For tacking the virus attacks the wireless networks don't have the state. The antivirus software in mobiles taking is too difficult to use in to account the power consumption. In mobile phones virus able to be spread through Bluetooth as well not only the operation system.
Mobile Banking Information Security Protection Methods:
By the beyond points, in mobile banking and network banking there is a lot of difference in security issues and as well security in mobile banking is additional challenging. So, in mobile banking we are using new security mechanisms which are dissimilar from network banking. The following part will tell regarding security tools in mobile banking.
Implementation of data Encryption:
Until at this time, the transaction layer has been applied by the security mechanism. While in mobile banking this is not sufficient as it wants secure information, confidential to be used, like PIN and password. By using Encryption technology we can overcome this problem which is furthermore used in GSM.
Initially, in mobiles having little operational capacity, the powerful security encryption wants excellent computing power also great storage capacity. In internet banking are using high quality encryption mechanisms which contain powerful computers as well as reach protection. Among less computing power of the encryption to reach advanced protection, mobiles will contain to use 2 algorithms AES & ECC which are asymmetric and symmetric respectively. Data protection increase the speed of encryption and decryption concurrently [2, 5].System and Data Integrity
Data integrity is able to ensure by the process of data transmission in constant monitoring and failure of records. The data loses its integrity because of the viruses and other malicious infections on equipments like carrier channel, gateways, and servers. The broken data caused in the transmission should be processed with tools which avoid this non-integrity. This can be done by making use of suitable provisions like firewalls, rapid recovery and intrusion detection which will ensure security of the data too. These tools must be in position to test the code's integrity which in turn assures the entire mobile banking system's integrity [2, 7].
In defence, the other security tools in mobile banking Authentication acting as a significant role. Customer Authentication will require password, phone numbers, and other identification information to sign contract with bank. In an open environment the chance of loss of mobile, easy to remember the valuable information & bank passwords accessed by the hackers. In such type of situations South Korea was developed by dynamic authentication. This system DAS4M is based on WIPI mobile platform. In screen the characters are displayed, in this, we have to utilize the equal info on the keyboard which will change the password. The security in mobile banking subsequently improves accordingly learning dynamic password system& other mechanisms from network banking [2,5].
