There was a serious concern about data security for WhatsApp users.Now WhatsApp’s end-to-end encryption will assure that user’s messages,videos,photos can’t be accessed by anyone else ;now WhatsApp,not cyber criminals ,not law-enforcement agencies.This is not enough ,you may able to encrypt even calls and group chats.
Jan Koum,co-founder of WhatsApp states that company has been working for the last two years on the feature.
Koum said,”We’ve been working for the past two years to give people better security over their conversations on WhatsApp… People deserve security. It makes it possible for us to connect with our loved ones. It gives us the confidence to speak our minds. It allows us to communicate sensitive information with colleagues, friends, and others. We’re glad to do our part in keeping people’s information out of the hands of hackers and cyber-criminals.“
Users need to stay on the same versions of WhatsApp to ensure that their chats get end-to-end encrypted.If you start to chat with the recently updated version of WhatsApp you are likely to see a message saying,”Messages you send to this chat and calls are now secured with end-to-end encryption.”
You may use this feature by just simply scanning a QR code of your friends phone(the option is there at the bottom of the same page) if they are nearby,if the QR code matches ,then the chat is encrypted and a green tick appers;but unfortunately it appears an exclamation mark in red alerting a user that the chat is not encrypted if code doesnt matched.
