I'm focusing on an internet site growth and development of rating site.

How do i restrict customers not create another account in the same pc?


For instance, user register to my website and may publish reviews and rate with a product. But i'm not going him/her to continuously review and rate exactly the same product over and over to avert this i restrict customers to publish only limited reviews or some think like this....(this is accomplished)

The issue is, chance of user can make another account in the same pc, in by doing this he/she will create multiple accounts... and publish reviews &lifier rate exactly the same product. With this problem I would like some mechanism to collect some unchangeable info from the user-PC therefore if he/she attempt to create another account i.e. THIS PC has already been registered with another account.

You will find some site of rating which supplies this to safeguard illegal reviews and rating... i think about MAC ADDRESS nevertheless its not the proper way i discovered!! to date

Regrettably there's not a way to 100% restrict people from making multiple accounts. You are able to at best allow it to be hard for individuals to make multiple accounts.

One particular way could be delivering out a validation sms for their mobile number having a x digit code they need to enter to accomplish registration. You can do this through various online sms gateways.

how does one determine if will still be exactly the same person on a single machine? as with a kiosk, or perhaps an internet coffee shop. let's say it had been another user who exactly the same factor - register and review? can you risk "banning" that other legitimate user simply because he/she used exactly the same PC and did exactly the same factor the prior person did?

if you would choose this, i would recommend which makes it harder to produce another account. like for instance, facebook - for just one account, a minumum of one email. and before you do stuff, validate that email first. this could require person to possess a valid email, which requires another group of sign ups - demanding!

there's not a way of stopping someone to register another account without jeopardizing the potential of another legit user. like they always say "with perseverance, that you can do anything!"

I do not think that there's a method to do that safely. Even when you can research something similar to a MAC address in javascript, the consumer could always just hack their browser to come back an incorrect value.

I'd say you need to record the ip, set a cookie, etc, that will stop an informal person.

(Another approach would be to require the consumer to go in a distinctive cell phone number that you simply send a code to - but many of people will not make use of your website if one makes it very difficult to register)
