Who is behind Babelnet?

Babelnet was created by OKsystem a.s., a private and independent software company headquartered in Prague, Czech Republic. OKsystem is constantly refining Babelnet to ensure it remains at the forefront of secure data and communication transmission technology.

How does Babelnet differ from its competitors?

  • Babelnet was primarily developed for businesses and enterprises to secure their business communication using strong cryptography protocols and end to end encryption.
  • Babelnet has a very clear, transparent and understandable license- based business model.
  • Babelnet supports enterprise level features such as LDAP / AD synchronization, API integrations, server on-premise, etc.
  • A Babelnet server can be on-premise or in the cloud to meet the various needs of our clients.
  • Babelnet is developed and produced by OKsystem, a bona-fide IT company that has been on the market for over 25 years with close to 300 employees and international partners.

Babelnet Pro on-premise and cloud are commercial products, where clients pay for licenses and support in a form of a one-time installation charge and monthly (or yearly) license payment. There are no hidden fees, advertising or spam.

Security

How strong is the encryption?

Babelnet uses end to end encryption among all the end-points, always verifying message integrity and correct sequencing. Babelnet server does not possess any of the private keys that could decrypt the messages. No data is stored on the server longer than necessary for the platform to function properly. Babelnet’s security is being continuously tested by independent 3rd party companies to ensure there are no weak spots.

Can a Babelnet server read my messages?

No. Messages are encrypted end to end, meaning that the server does not take part in the encryption process.

Are messages encrypted while stored on my device?

Yes. All messages are kept in an encrypted form in the Babelnet application.

How are my messages protected in case of a device loss or theft?

Messages are kept encrypted in the application and the device’s main encryption key is protected by your password. On the iOS platform, the application uses additional system support of data and database encryption. The mobile device must not be jailbroken or rooted. IT IS NECESSARY to use a strong password and it is RECOMMENDED to activate the remote wipe- out option.

Can anyone track my activity?

Babelnet encrypts and protects the content of your messages. The server is not hiding the fact that communication as such took place.

Is there a backdoor?

No. This is not even possible since all of the communication is end to end encrypted and not even the servers or administrators have access to the private keys used for encryption and decryption. Such keys (private keys) are generated and stored in an encrypted form on your devices only.

How is Babelnet integrated with a company’s directory services?

Babelnet servers can (if configured) import users’ accounts and phone numbers from the company’s LDAP directory (e.g., an Active Directory). This significantly simplifies Babelnet administration. Babelnet can be also configured to synchronize any changes in LDAP (creation, changes, deletion).

Using Babelnet

Why do I need to create a Babelnet Password at the very beginning?

All messages and attachments in the Babelnet application are encrypted using an encryption key, which is protected by your password. Therefore it is important to choose a strong password - as a rule of thumb we recommend using passwords that have at least 12 alphanumeric characters resistant to “dictionary attacks”.

You can enable the use of a numeric PIN or fingerprint access on your mobile devices for easier application access. Since these are weaker mechanisms, the application will ask for a strong password should the PIN or fingerprint be repeatedly unrecognized.

Verification codes do not match – what should I do?

There are 2 possibilities why this has happened.

The first and more probable reason is that you or your recipient has a new Diffie-Hellman key pair, probably due to reinstallation of the application. The new key pair will be automatically synchronized but you can always speed up the synchronization by tapping on the “synchronize” button in the server settings in your application.

A second reason could be, that somebody may be trying to perform a man-in-the-middle attack to hack into your conversation. In that case please contact your Babelnet administrator immediately.

“Next part of message has been added” - what does this mean?

In some cases long text messages (SMS) may be divided into two or more parts. If this happens, just tap the link in each message (SMS) – after you do this for all messages (regardless in which order), the divided message will be decrypted in Babelnet application.

I deleted a message but would like to read it again, is it possible?

Deleted messages are permanently deleted from one device. If you have multiple devices registered under your account, the messages are still there.

What do the Add and Block buttons mean?

Add and Block buttons were implemented to protect Babelnet users from receiving messages from unwanted contacts and appear in conversations with other users who are not currently in your Babelnet contact list.

By tapping “Add” you confirm that you wish to add the contact into your contact list and thus allow the person to send you encrypted messages via Babelnet. By tapping “Block” you place the contact into your blocklist and they will not be able to send you messages until you unblock the contact again.

How to block contacts?

Find the contact which you wish to block in your contact list and display the details. Then you can block the user. It is always possible to unblock contacts later if you go to settings – blocked users.

Why can’t I write into a conversation?

It is not possible to write into a conversation when there is one or more blocked contacts in the conversation thread. It is necessary to either unblock the contact or remove them from recipients.

Why are there exclamation marks next to some of the messages?

Should a message not be delivered to one or more of the recipients, a warning is displayed next to the message. More information can be found in the message details.

I forgot my Babelnet password - can I still see my messages?

Unfortunately no, for security reasons we do not allow password recovery as it often creates a security weak spot. Your Babelnet messages are encrypted on your device and in order to decrypt and display the messages you need to type in your password. In order to start using the application again it is necessary to reinstall the application and start over. This is part of Babelnet’s security approach.

What happens when I delete a server?

The server and all associated contacts will be deleted from your device. Conversations will remain but will be marked to let you know that the associated contact has been DELETED. If you register to the server again, the newly downloaded contacts will not synchronize with the DELETED ones (even thought it might be the same person). This is part of Babelnet’s security approach.

Why are some of my contacts displayed with their Babelnet address only and not a full name?

These contacts are unavailable or have been deleted from the server. If they become restored or available again, associated contact information will be displayed again.

What should I do if the SSL certificate in my administration console appears to be invalid?

Download a root certificate HERE and install it as a trusted certificate.

Warnings

Warning: Contact X has a new key

This is a warning displayed in a conversation when one of the recipients has changed his / her key. In most cases this is because the user has reinstalled or changed his / her device and did not transfer the old key from another device. It is advised to call that person over the phone and verify that this is the case. If not, please contact your administrator.

Warning: User has probably re-installed his / her device

This warning is displayed in conversations when a message with an invalid sequence number was sent by one of the users. This typically happens after the user has started using Babelnet on another (new) device and has transferred their old key to this device or after the user has reinstalled the Babelnet application on their device. It is recommended to call that person and verify that this is the case. If not, please contact your Babelnet server administrator immediately.

Warning: Data transfer has failed

When this error is displayed, please contact your administrator immediately, it could be due to an attack on your Babelnet server.

Troubleshoot

There are no notifications when the application is stopped.

Android

This problem is present on Android devices from several manufacturers (e.g. Huawei and Xiaomi). It is caused by the manufacturers design to prolong battery life. You need to add Babelnet to the list of protected applications on Android devices from these manufacturers.

  • Huawei

  • Xiaomi

    1) Settings -> Manage Apps' Battery Usage -> Choose Apps.
    2) Settings -> App Notifications

A problem with contacts or writing messagess

All platforms

In the Babelnet application go to Settings -> Servers -> click on the server which is causing the issue and click on "reset data" at the bottom of the screen. The application will restore all contact data from the server.
