Money transfer on internet is happening very
fast. Money applications for payment of salary have been
made on the internet. Due to which cases of fraud are
also increasing. İn this paper, we have made a little
effort to remove this fraud from the hidden markov
model. Here, we have used K-means algorithm. The Kmeans algorithm has been used for symbolic and
frequency transactions. Starting is normal behavior with
HMM account. Any transaction is considered fraudulent
if the transaction does not go through the HMM process.
Here is an example of real world bank, in which the
experiment has been validated by simulation and the
model used. İf we look at the old data, then this model
works well at low medium frequency.
