Validating and securing caller identification to prevent identity spoofing

A non-transitory computer-readable medium storing instructions, the instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the one or more processors to:
• receive call information associated with a call from a first user device to a second user device,
• the first user device being associated with a first network,
• the second user device being associated with a second network that is separate from the first network, and
• the call information including a cryptographic signature associated with a caller identification;
• utilize a public key to determine whether the cryptographic signature and the caller identification are verified;
• remove the cryptographic signature from the call information when the cryptographic signature and the caller identification are determined to be verified;
• add authentication information to the call information when the cryptographic signature and the caller identification are determined to be verified;
• and
• cause the call information and the authentication information to be provided to the second network for routing to the second user device.

A method, comprising:

• receiving, by a device, call information associated with a call from a first user device to a second user device,
• the first user device and the second user device being associated with a network, and
• the call information including a caller identification and being received via an originating network device of the network;
• determining, by the device, whether the caller identification is verified;
• appending, by the device, authentication information to the call information when the caller identification is determined to be verified;
• receiving, by the device, the call information and the authentication information from a terminating network device of the network;
• determining, by the device, that no verification of the call information and the authentication information is required since the call remains in the network;
• and
• causing, by the device, the call information and the authentication information to be provided to the second user device.
