Here it comes - encrypted P2P multimedia messenger. Chat, make voice, video and conference calls, send files and documents using secure P2P (Peer-to-Peer) data transfer technology.
We implemented most recent achievements and cutting-edge technologies in IT security to develop cryptographic protection mechanisms for our messenger. The level of encryption and its performance meets the most stringent banking standards
Your private or business information is totally safe and confidential when using our messenger. SafeUM eliminates any possibility of data interception and spoofing and also provides the parties' authentication. Here's more information on the technology, cryptographic systems, functionality, and features:
>> Encryption. The information is encrypted by subscriber A, stored on the server and transmitted in encrypted form. After going through communication channels it is decrypted by subscriber B. The information is open only at the end nodes - where it is encrypted – users' mobile phones or tablets. Any other equipment such as servers, switches, routers and SafeUM servers contain encrypted information. In case the user does not trust the cryptographic service provider he can use the P2P mode which eliminates the technical possibility of interception.
>> P2P mode involves direct data transfer between users bypassing our servers. The communication channel is not limited to the server capacity which distinguishes SafeUM from all other popular messengers.
>> Digital signature is another reliable way to protect data during transfer. This automatic technology authenticates the parties and ensures data integrity. Account and chat hacking, as well as spoofing, are totally eliminated.
>> Hybrid encryption scheme. A symmetric block encryption algorithm is used to increase the encryption performance. To transfer the encryption key in the data exchange process an asymmetric elliptic curve cryptography is used. It has high levels of cryptographic security with a relatively small key length. This hybrid scheme allows to "take the best" out of each system and combine into one cryptosystem with very good encryption performance and cryptographic security as well.
>> The ElGamal scheme is used for symmetric key transport. SafeUM cryptography experts implemented complex algorithmic optimization of the encryption process taking into account the stringent requirements of the banking sector. The application works fast and ensures high-quality communication without any delays. In other words - the communication quality is equal to that of the other messengers but, at the same time, it provides a very high level of security and extremely fast encryption performance.
>> Our servers have no hard drives. We use Redis in-memory database - the best option for SafeUM that allows storing all (!) the data in RAM. Third parties can only access these data after going through a complicated legal and bureaucratic procedure. And even then SafeUM can disclose only the encrypted data. Only you have the private keys which are stored on your device RAM. They are generated on the basis of the passphrase that the user must remember. We, being the providers, cannot decrypt messages stored on the server. In case you don’t trust us as providers you can activate the P2P mode. Thus the encrypted information will be transmitted bypassing the server, eliminating any technical possibility of its interception.
>> SafeUM multimedia messenger comes with an exclusive set of functionality. You can simultaneously use up to three accounts online in one messenger. No phone number is needed to sign up. What do you think about the disable chat history saving feature? How about the screen shot protection during the dialogue? And voice modification feature? SafeUM uses a system of three security PIN codes: first is used to sing in, second - to access secret contacts and chats and the third one - to deactivate the account in case of emergency.
