According to the query of Baidu Law Pro. Com, receiving a strange phone call will not reveal personal information, because voice and mobile phone address book and related materials are two completely different systems, and I have never heard of this technology. Even abroad, I have never heard of such technology and cases.
Pay more attention to prevent personal information from leaking: beware of phishing websites in online shopping. When buying goods through the Internet, carefully check the login website, do not easily receive and install unknown software, carefully fill in bank accounts and passwords, and beware of phishing websites to prevent economic losses caused by personal information disclosure. Properly handle documents containing personal information, such as express orders, tickets, shopping receipts, etc. The courier has the name, phone number and address of the online shopper, and the ticket and plane ticket are printed with the name and ID number of the ticket purchaser. The shopping receipt also has some information such as name, bank card number and consumption record. Inadvertently throwing it away may fall into the hands of criminals, leading to the disclosure of personal information.
