Specialists and technologists told "Tech" that after the increase in cases of penetration of applications with smartphones, and Facebook's attempts to encrypt data, including WhatsApp data, another situation emerged that is considered a breach of the system.
However, this breach, which may put your information at risk, whether photos or videos and other materials that you exchange with friends, and retrieve them without your knowledge, relates to the user's own error, and not a weakness in protecting user data.
This error is represented in the user changing the phone number on which to rely on to use "WhatsApp", or that he creates a new account without deleting the old account, as in the event of dispensing the SIM card, and the company providing the communication service displays the same number in the markets from New This will result in the user losing their privacy. Once someone else gets the number and creates an account on WhatsApp, this person will be able to retrieve all of the conversations, photos, and videos.
To solve this problem, the user who wants to dispense with his phone number, which is used for "WhatsApp", must enter the settings and choose the account, including the option of Delete Delete, in order to delete the account from the company's servers entirely, and avoid such an occurrence.
