Published On August 23rd, 2022 Tech Talks

Are you looking for some best secure messaging apps, and want to know more on its protection strategies to protect your data?

Then this is your guide. Well, here I have put in my research study to get you what you want – From security-privacy protocols to their factors and tools, you will get to know every aspect of encryption here.

So, with no more delay let’s get started!

What is Chat Security & Why it’s Importance!

Chat messaging apps, the trending technology that has made connections and communications at everyone’s reach, making people think over security – the encryption.

Well, encryption is the process where the text data is converted into a cipher (a non-readable content), which maintains and protects the privacy of the message from any third party. 

Some of the benefits of these encrypted data includes:

  • Full Protection on Personal Information : Encryption ensures a safe transmission of any personal or business related data over the internet.
  • High Data integrity : Generally, it’s very difficult to hack any encrypted data. So, if someone tries to breach the data, the system will notify the issue instantly and avoid the theft in the first place.
  • Data Protection Across Multiple Devices –  Whatever be the device, encryption ensures a complete protection over user’s data despite of devices.

Examples of Chat Privacy Regulations

As privacy is the major priority in all terms, the government has put in many regulations and instant messaging protocols. Let’s have a look at some of them

General Data protection Regulation (GDPR)

GDPR refers to the set of rules that regulates the process of how the companies can collect, store, maintain, and share their customer’s personal data ensuring security. Here, the businesses can never neglect GDPR as they can ruin them in terms of sales and marketing activities.

Health Insurance Portability and Accountability Act (HIPAA)

HIPAA privacy rules establish national standards for the protection of patient’s health information. It is necessary for the companies that prepare the software for healthcare organizations to follow the HIPAA compliances – to store, share , manage and record the patient’s PHI (protected health information).

System and Organization Controls 2 (SOC 2)

SOC 2 is a compliance standard for service organizations, developed by American Institute of CPAs (AICPA) – This specifies the organizations as to how they should manage their customer’s data. Its standards are based on Trust Services Criteria – security, availability, processing integrity, confidentiality, and privacy.

International Organization for Standardization 270001 (ISO 270001)

ISO 270001 is an international standard that provides the requirements for an information security management system (ISMS). This permits all kinds of organizations to manage the security over their assets including financial information, employee details, and intellectual property.

Now, let’s see what are the possible ways these privacy policies can impact the trust and adoption of any user.

Impact of Chat Privacy on User’s Trust and Adoption

When it comes to any type of organizations, security is the top priority for both cloud and SaaS adoption. Moreover, it has been found that privacy concerns affect an individual’s behavior with trust in both the ways – direct and indirect.

A study with Ping Identity report, shows that for almost 43% of IT professionals security is the basic obstacle for cloud adoption, whereas 37% states SaaS adoption to be an obstacle. But, the reality is that both the end demands the same “security.”

Let’s have some further look with different apps in terms of security for more clarity.

Popular Messaging Apps with their Top Security Protocols

After a brief explanation about the impact of these security measures over some of the top apps, let’s study in detail with some other popular secure messaging apps.

1. WhatsApp

WhatsApp is one of the most popular instant messaging apps that has over two billion active users. Some of the security measures used by WhatsApp includes

  • End-to-End Encryption : WhatsApp uses end-to-end encryption protocol in their application, where the recipient has the keys to decrypt the messages sent by the senders through their app.
  • Verify Encryption – WhatsApp enables its users to confirm the calls and messages data to be fully encrypted via a verify security code screen.
  • Two-Step Verification – This allows the users to protect their account with a PIN which needs to be verified by their phone number.
  • Unstored Messages – As per WhatsApp policy, it will not retain any user’s private messages. They will be stored in the app’s server too when they are being delivered from their sender to reach the recipient.

2. Signal

Signal is one of the most secure messaging apps that uses a privacy-preserving technology to remove the risk of leakage while sharing or sending messages to any non-intended recipients. It uses end-to-end encryption as an advanced level of security over their user’s data.

Moreover, its layer of security protocol permits their users to choose their desired time frame to disappear the data. If needed they can also set this timer for every conversation in the app.

3. Telegram

Telegram is one among the top secure messaging solutions that are utilized to encrypt bulk of conversations. It provides the users with the option to perform self-destruction of messages, images, documents, and video after a certain period of time automatically.

However, sometimes it allows the users to turn on the secret chats and  forces the application to get deleted when the user is not in need of it.

4 . Pryvate

Pryvate is a secure communication platform that delivers security of military-grade encryption for all businesses and personal communication across iOS and Android devices. This includes triple-layered security that is powered by 4096-bit encryption, with AES – 256 key management and DH key exchanges. 

Moreover, it offers an independent network that does not depend on servers for their security issues instead connects the sender and recipient directly.

5. Threema

Threema is the most trusted open-source messaging app that is fully encrypted across multiple devices. Its server design allows the messages to delete permanently once delivered to the recipient. Although the server manages all the information automatically on the user’s device, this information will still be protected against all types of hacking and thefts.

Moreover, it allows the users to check for the accuracy of the encryption, without a need for email or phone number to get sign-up for security issues.

Best Chat Security Features that Turns-on User Engagement

Security is the major concern for any chat solution provider as it will directly impact the commercial side of an app’s success. So, let’s have a look at some of the chat security features

1. End-to-end Encryption

End-to-end encryption aims at providing complete security over the chat messages by encrypting them so that no third party can interrupt the message in between. 

2. Data Masking

Data masking is a process where a fake version of the original organization data is created. The main aim is to protect the sensitive data using the functional alternative, when there is a need for some real one.

3. XSS Filter

XSS filter is the type of cross-site scripting attack that’s found in web applications. It generally permits the hackers to bypass the security mechanism by inserting the malicious scripts into the web pages that have been viewed by the users.

4. Disappearing of Messages

This security feature is an extension of any security as this allows the messages to get deleted automatically after sometime of its arrival at the recipient end. This extension works across both one-on-one as well as group chat.

5. Password Security

The password security is an essential part of data security which will dismiss all the possibilities of hacking. This system involves a variety of features that include HTTPS authentication, password encryption, CAPTCHA with account lockout, and password complexity standards.

6. Cookies & Session

 They are the one that stores the information in the browser memory and will be available for the duration of the browser session. 

7. Virus & Malware Scanner

The virus and malware scanner extension allows the developer to perform a deep scanning over the uploaded files of users to prevent the malware infection. This scanning process involves multiple tools and techniques to identify the issue.

Now, let see further what are the requirements that need to be noted before planning to build any chat security features.
