Abstract
A number of problems are associated with the generation, management and security of PINs, a subset of password. The PINs may be recharge card used by GSM operators or for authentication in ATM. The problems associated with the use of these PINs range from scratching off any of the recharge PIN numbers in recharge card to loss of PIN number or entering invalid number in the case of authentication. It usually takes time for the customer service of the service provider or system administrator to provide convincing solution to these problems promptly when it occurred. PINs generation could seem like simply arranging ranges of number and feeding it into the telecommunication systems such as mobile handsets or ATM to grant access but it requires a specialized and secured way to generate, store and manage it in order to achieve prompt access. This paper focused on the development of database concept to provide solution to these problems by desiging a system by which the PINs generated can be effectively stored and managed so that userss can have immediate access to the PINs if they can provide the identification number on the card. Succintly, the paper discusses the design of a system that generates, manages and secures PINs application using Visual Basic Version 6.0 for designing the front and interface and Microsoft Access 2007 as the database. The system was implemented using real data and the result was successful.
Highlights
A password is a secret word which is characters, numbers or combination of both that is used for access approval to gain access to a resource
The primary objective of this research is to use database management system to design a fast, reliable, effective and efficient mode of generating, managing and ensuring the security of recharge card PINS to the telecommunication industry which bis capable to carry out Personal Identification Numbers (PIN) enquiry in case where customer lose any of the PIN numbers in the process of scratching the card
The VISA method takes the right most 11 digits of the Primary Account Number (PAN) excluding the checksum value, a PIN validation key index (PVKI) and the required PIN value encrypted with the PIN validation key (PVK) referenced by the PVKI
Summary
A password is a secret word which is characters, numbers or combination of both that is used for access approval to gain access to a resource. Afeni use of their resoueces by their staff and or clients/customers Global System for Mobile Communication (GSM) is a satellite based facility that largely works wirelessly with its base/terminal remotely location in order to allow effective signal transmission to the device known as handsets. It is an open, digital cellular technology used for transmitting mobile voice and data services [1] [2]. Ericsson forecasts that mobile subscriptions will reach 9 billion by 2017
