  • Patent number: 11677872
    Abstract: Apparatus and methods for enhancing security of an authentication process of a caller that initiated a call in an Interactive Voice Response (“IVR”) system are provided. The methods may include routing the call through the IVR system to a headset. After the routing, the methods may include retrieving data associated with the caller. In response to the retrieved data meeting one or more predetermined conditions, a graphical user interface of an agent computer paired to the headset may display a plurality of validation information for validating the caller. Selection by the agent of validation information may trigger methods for transmitting a request to the caller, via a caller mobile phone, to input the validation information selected by the agent. The methods may additionally include authenticating the caller based at least in part on the information input into the mobile phone.

  • Patent number: 9698975
    Abstract: There is provided a method and apparatus for resetting a password for a device or managing the device, the device having an encryption perimeter. A device shares a public/private key pair with a server, the public key being on the device and the private key being on the server. An intermediate value is encrypted on the mobile device using the public key. If the password is lost or the device needs to be managed, the server can request the encrypted intermediate value, decrypt it, and send the decrypted value to the mobile device which may then resume operations. A new password may be provided by the server or the user may set a new password once the encryption key is recreated from the decrypted intermediate value.
