Email is the most important application when the Internet starts. SMS is the most important function when the mobile phone appears. But with the evolution of the times, people are increasingly needing instant messaging, which leads to more and more abandoned emails, and the security of mobile SMS is worrying. In the age of electronic communication, if you care about privacy, don’t want others to “sneak a peek” at your communication, what should I do?
Each chat or communication platform has varying degrees of privacy protection. Apple said on its website that encryption protects hundreds of millions of online transactions every day, including shopping, paying bills, iMessage or FaceTime or Whatsapp. Apple said that the encrypted information becomes undetectable by third parties.
This has always been a hot topic in Washington. Attorney General William Barr wrote a letter to his face asking for a change in Whatsapp’s encryption policy. Bar said: “We must find a balance between protecting public information while protecting public safety. Law enforcement agencies can also use this information to protect the public, investigate crimes, and guard against the future. It is opposed by Facebook.”
First of all: Email is not safe
Popular webmail (webmail) such as Google Gmail, Microsoft Outlook or Yahoo Mail is not encrypted, and government or corporate emails are not encrypted. So it’s easy to track. Li said.
But there are a few startups that offer encrypted email, including Proton in Switzerland, and Microsoft provides encrypted Outlook to paying users, but it is very cumbersome to use, so you must first encrypt the email and send it to the recipient a “digital key” to let him Can read.
Security comes from the right settings
Since emails are not secure enough, mobile phones and text messages are a little better. “But don’t use the company’s mobile phone.” Li said: “Because many companies have spyware, you can intercept photos of what you are doing. It is best to use a personal mobile phone.”
The Samsung Galaxy Galaxy series has a feature that encrypts information and can be stored on an external SD card. However, it should be noted that after encrypting the information, it can only be interpreted on the same mobile phone.
In addition, Apple phones have a feature that prevents law enforcement or the government from using USB devices to break into the phone and get unencrypted data. Click on “Settings”, touch the ID and password, then scroll to the USB accessory at the bottom and click “Close”. In this case, if the phone is locked for more than an hour, the USB device can no longer connect to your iPhone.
Security depends on you and the other person.
What mobile phone to use
Apple said that text messages sent between Apple phones are encrypted, so if you don’t decode them, you can’t read them. Apple said that as long as the two-factor authentication login is selected, the SMS stored on its iCloud service will also be encrypted. Please note that if the other person is not using an Apple phone, it will not be encrypted.
Encrypted chat program or best choice
Signal, Wire, Rakuten Viber and Whatsapp are popular apps for encrypted written and spoken conversations. Let’s talk about Whatsapp under Facebook. Since Whatsapp is the world’s hottest chat program with more than 1 billion users, it’s likely that the person you’re talking to is also using it. Li said that being able to communicate freely and privately is a huge bonus. The website has a detailed explanation on this, saying that the company employees do not read customer communication consultation. However, Facebook does have access to your relays and can confirm who you have been talking to. Li added.
Based on Japan, Rakuten Viber said on its website that it provides a “secret chat” feature that automatically destroys information after communication.
But privacy is only “private” in your eyes, because people on the other end of the encrypted conversation can easily take screenshots and share them with the world. However, Facebook said that this information should only be directed to the two sides of the communication: you and him, not including anyone else.
