The Signal app is not new, but it has recently begun expanding its services, posing a threat to WhatsApp and its owner, Mark Zuckerberg.

وأكد تطبيق التراسل “Signal”، والذي يُعتبر الأكثر أمانًا، عن استعداده لمنافسة واتساب; the app’s creator, Moxie Marlinspike, announced that

Signal will undergo several changes after being developed to make encrypted communication easy for anyone to use.

Despite WhatsApp’s advantages and popularity, some users are still looking for greater security and privacy—something that it provides.

تطبيق “Signal”.

Messaging app enthusiasts have raised a forward-looking question: Could this app take WhatsApp’s place following the potential leap

it may make in its services in the coming period? The answer will become clearer after we review the pros and cons of both apps in this article.

*Security and Privacy

.

-تشفير التطبيق

The In-App Encryption feature lets users encrypt the app itself. All messages are securely encrypted before being saved to the drive

on your Android device. A secret code set by the users themselves is used for this purpose.

.

-Metadata Encryption

The app offers users a feature called “Metadata Encryption,” which encrypts metadata, keeping the media content

you share in the app safe and encrypted.

Metadata refers to stored data such as image size, pixels, camera model, and more. The Signal app also provides complete data security.

This includes metadata, as well as strong encryption and protection against hacking.

.

-Backup Encryption

The app lets you encrypt backups using its “Backup’s Encryption” feature, making your messages more secure and preventing easy access

to your messages by hackers.

Signal also provides end-to-end encryption for messages stored in backups, ensuring that no one can view your private messages.

*Security vulnerabilities in WhatsApp

You won’t find the features mentioned above in WhatsApp. Backups of messages created in the WhatsApp app are not encrypted on

At launch, this means it can be accessed very easily by hackers, unlike Signal.

*Anyone can access your messages

WhatsApp does not support encryption for messages stored on your device, allowing anyone to access your messages if they

use your device.

As for metadata, WhatsApp still leaves metadata unencrypted, which poses a serious risk. This means that the way

Encryption for metadata is not very strong.

Simply put, the worst thing about WhatsApp is that it stores data in the wrong places, where it is easy to access and visible to all apps.

Although WhatsApp cannot access your conversations or photos, or listen to your voice recordings, it can still know

who you’re talking to, and can access your address book. It can also sync your data with its parent company, “Facebook.”

The “Signal” app works much like “WhatsApp”: you sign up with your phone number, and it shows you which of your friends are registered on the app. It also offers users the option to

automatically delete messages after a set number of minutes.
