How Safe is End-to-End Encryption?
In the last couple of years, the phrase “end-to-end encryption” has been appearing more often around the Internet and in the news . What exactly does it mean and how safe is it really?
End-to-end encryption is a method of secure communication that prevents third-parties from accessing data while it’s transferred from one device to another. In end-to-end encryption, the data is encrypted on the sender’s device and only the recipient is able to decrypt it. Nobody in between, whether they are the Internet service provider, application service provider or hacker, can read it or tamper with it. The cryptographic keys used to encrypt and decrypt the messages are stored exclusively on the sender and receiver’s devices.
Many mainstream communication platforms have adopted end-to-end encryption, including Apple iMessage, Whatsapp and Facebook Messenger, but how safe is this technology? Does it really protect your messages from the minute you send it till your recipient reads it?
Telegram Messenger is a communications app that offers end-to-end encryption for its users. Previously, we had learned that hackers can easily break into a Telegram messenger account by intercepting user authentication text messages. Recent news reports have revealed a bug in Telegram that any information the user copies and pastes into their Telegram chats will be logged into syslog on macOS. Hackers can then find the syslog file and see messages from user chats.
This shows that end-to-end encryption has vulnerabilities depending on the application service provider. Let’s now discuss how CoverMe has been designed to prevent these vulnerabilities:
- CoverMe does not support log-in from multiple devices, removing the possibility for the kind of user authentication texts that allowed breaking-into Telegram accounts.
- User data is never saved on CoverMe’s servers, removing the risk of hackers breaking into our servers and accessing user data.
- CoverMe has effective intruder alarm notifications to alert you when someone has tried to break-into your account. When someone enters the wrong password to try to enter CoverMe, your phone’s front facing camera will take a picture of the intruder. The photo, time of break-in and even the GPS location of the break-in will be saved in a file for you to check later.
As you can see, not all end-to-end encryption apps are built the same. CoverMe has been carefully designed by security experts to be safe, reliable and protective of your personal data.
