am still hoping on some thing, the reason for the project password authentication without data base is to circumvent the security issue of password verifier being stolen on the server which can still make the adversary to implicate a rightful user i have an idea but the only problem i am having now is problem that it is still impossible for a user to be change his password if need be what i did to generate the password is that i used a message hash which will use some of the attributes summited during registration to get a password which will be given to the user user will then submit his password and also the other field when logging in the server will then try to use the fields to see if it will generate the supplied password if not it will not authenticate the user i will see to it that you will get the code later today pls i need the solution in java

Stay with the original thread, please.

hi i have a project to create an Expert System in the medical line the system should calculate Body Mass Index then check for some conditions like Under weight and Over weight and can precise treatment for the conditions.Can you help?

Of course, if you have a specific question.

the trend these days is to take whatever weight the person enters and tell them they're severely obese and need immediate treatment by the most expensive doctors they can find.
