C2Call GmbH has been developing video chat, voice calling and messaging solutions for the computing cloud since 2008. As one of the pioneers in mobile communication over Internet Protocol, we launched FriendCaller back in 2009.
Today FriendCaller has more than 12 million registered users across all popular mobile communication platforms; including Apple iOS, Android devices, Amazon Kindle, on Facebook, and on desktop web browsers.
Our SDK is available for mobile app developers free of charge. By integrating C2Call's technology into their mobile apps, developers can now have their users communicate across multiple apps, on multiple platforms. App users can then use video chat, rich media messaging, group audio and video calls and share location info with other users, all within one app
As part of our mobile life people are using messenger and VoIP clients to communicate with friends, colleagues or customers, exchanging information, doing calls and simply being socially connected.
As the recent discussion on Internet security and privacy has shown, the Internet is not a safe place and we are all sharing information day-by-day which is supposed to be private but actually isn't.
Popular messaging and calling apps have hundred millions of users. And while the communication between the Apps and the servers is typically encrypted, the actual information is stored on the servers un-encrypted and can be often accessed by all employees involved in managing theses servers.
In order close this security hole, C2Call has now introduced Public/Private Key based End-to-End encryption on its C2Call SDK and its consumer service FriendCaller.
Private & Public Key
What does that mean? Public-/Private Key encryption is an asymmetric encryption based on a Public- and Private Key pair. The owner of such key pair can publish his public key and keep his private key secret. In case somebody wants to send an encrypted message, he will use the public key of the receiver to encrypt the message. Only the receiver who owns the private key can then use the private key, to decrypt the message.
The C2Call SDK and FriendCaller are now providing such a Public/Private Key infrastructure. Every user will automatically get his personal Public/Private Key pair generated on his device.
The public key will be automatically published through the C2Call network and the private key will be kept secret on the users device only.
C2Call Secure Communication
Sending a message using the C2Call SDK or a FriendCaller client will now be automatically encrypted using the public key of the receiver. No information will be stored un-encrypted on the servers any longer. Even multimedia attachments like photos, videos, voice mails or documents (PDF, DOC, etc.) will be end-to-end encrypted and can only be read by the intendant recipient. Encryption is available for group communication as well; only the group members are able to read any messages posted to that group.
As special offer to large corporations, C2Call now offers it's secure communication client for VoIP, Video Telephony, Conferencing and Multimedia Messaging to enterprise customers as white labeled communication app.
This will ensure full privacy on corporate communication. Stop sharing corporate private information with unauthorized people on the Internet.
C2Call offers its communication client based on the C2Call SDK, similar to FriendCaller fully branded as customer client and all backend services hosted in a virtual private cloud for the customer as standard package.
