Access control to Multi-Signature and Single-Signature
cryptograms through fingerprint recognition

We have implemented an additional layer for accessing encrypted secrets: the biometrics of the rightful owner.
Cuvex BIT, as a secure cryptographic device, has a state-of-the-art biometric sensor, capable of creating the fingerprint template of authorized users, essential for securely accessing cryptograms.
Now, Multiple Signature and Single Signature users can choose to add, in addition to the password used for encryption, a biometric access control.
This functionality allows a single password to be used for encryption, even if the presence of several people is required for decryption.
The system will request, in addition to the password, each of the fingerprints of the persons required to decrypt and display the encrypted secret.

Firmware update process via USB-C cable from our Cuvex App for Smartphones.

We have eliminated the Bluetooth module installed in hardware and replaced it with a firmware update via USB-C, which allows for a faster and more secure installation, responding to our customers' requests for a crypto cold storage device.
Reasons for upgrading via USB-C:
  • Better installation time and firmware upgrade.
  • To offer our customers what they have requested.

Cuvex BIT acquires Hardware Wallet capabilities with AirGap's new PSBT signature functionality

With our new device, used in combination with our Cuvex App for Smartphones, customers will have a complete cryptocurrency Seed phrase cold storage system, allowing them to:
  • Creating a wallet seed phrase with their own entropy (Dice and Coin Process).

  • Military-grade encryption of this seed phrase, with high redundancy at the lowest cost, by making copies of the cryptogram on NFC cards.

  • A privacy-based wallet with a comprehensive Coin Control tool, tagging and documenting every transaction so that you have control over your privacy.

  • Creating transactions in the Cuvex App and signing them via AirGap PSBT on the Cuvex BIT device.
