Signal App Protects User Privacy through Cryptography

(Last Updated on February 9, 2021)

There has been a large push towards decentralized and encryption technology for enhancing user privacy online over this past decade. Technology, like our beloved internet social media platforms, have become much more invasive and intrusive into personal privacy and user data.

An individuals right to privacy, both offline and online, will be increasingly more difficult to control as technology grows and integrates into our daily lives.

More than ever the majority of the globe is recognizing the need for privacy – especially user privacy online and over messaging platforms.

Say Hello to Privacy

Privacy is not an act of criminality or secrecy. Privacy is the ability to selectively reveal certain data about yourself – such as financial, medical, and personal information.

We know we need our privacy in our technology platforms, especially those that we communicate over.

Cryptography holds they keys to our sovereign privacy.

“Privacy in an open society also requires cryptography. If I say something, I want it heard only by those for whom I intend it. If the content of my speech is available to the world, I have no privacy. To encrypt is to indicate the desire for privacy, and to encrypt with weak cryptography is to indicate not too much desire for privacy. Furthermore, to reveal one’s identity with assurance when the default is anonymity requires the cryptographic signature.

We must defend our own privacy if we expect to have any. We must come together and create systems which allow anonymous transactions to take place. People have been defending their own privacy for centuries with whispers, darkness, envelopes, closed doors, secret handshakes, and couriers. The technologies of the past did not allow for strong privacy, but electronic technologies do.”

Eric Hughes A Cypherpunk Manifesto

Signal uses end-to-end encryption technology to ensure privacy.

The app has integrated encryption that allows the end user to independently verify their contacts and communication channel privacy. A very needed step in the world today, not only privacy for communications and data, but the ability to self-verify the integrity of the data your are using.

Message friends directly or setup group messages, completely private and can be used throughout the globe. Apps like Signal continue to empower the individual and protect privacy rights across borders and platforms.

Fast and easy setup which ties directly to your mobile phone number.

As technology evolves there will be additional needs to increase your online security and management of private data. Sophisticated methods continue to evolve and bypass generic protections to steal information such as financial accounts, identification, credit/debit card numbers, and 3rd party payment user access.

Signal gives you complete control over your account privacy – turn on or off various privacy features within the app.

All communication done through Signal app is automatically utilizing end-to-end encryption cryptography.

End to end encryption = data is only decrypted at the end point by the recipient.

All data stays encrypted during transmission and is independently verified by the recipient.

Self-verification of data integrity is huge.

Take responsibility for your own privacy and data – don’t leave it in the hands of someone else.

What can you send on the Signal app?

-> One to one and group text messages

-> One to one and group video calls

-> Files such as images, documents, voice, and media

How are you identified?

-> Mobile phone number only

Cryptography brings equality for all – but doesn’t bring funding for these companies..

Being a leader in decentralized and encrypted privacy platforms usually means you aren’t making much money in today’s business world..

Today’s corporations LIVE off user data – the whole marketing and advertising ecosystem is built off data collection.

Corporations are devouring massive amounts of user data for targeting audiences with giant advertising campaigns. The companies pushing privacy applications will have to do so with little to no outside or venture funding. They are going to need the community and users to support them.

And it won’t be easy..

Wait, so what are the other social media companies doing with our data?!

Most times your messages, communications, and all data pass through an intermediary, such as giant server databases or some cloud service like AWS. This data can be stored, indefinitely, and used per their “terms of service”.

User terms of service which are hundreds, if not thousands, of pages of complicated legal jargon that takes teams of lawyers to dissect and comprehend.

Oh and these user contracts are always changing – constantly updating and evolving as needed to skirt various user protection laws which fail to protect us.

We all have GIGABYTES of data left on servers and cloud services all around the world which can bleed out, be hacked, used for advertising, and lord knows what else.

We can continue down that path to be the victims of vicious corporate marketing campaigns and be the guinea pigs for future technologists in power.

Or we can take privacy and trust back into our own hands with services such as Signal.

Cryptography enables this.
