Abstract

A system and method for securely recording voice communications, comprising an authentication server, further comprising at least a software components operating on a network-capable computing device, and a database, wherein an authentication server verifies the validity of voice communications and a database stores voice communication recordings.

Claims

1. A system for securely recording voice communications, comprising:

an authentication server computer, comprising a first memory, a first processor, a first network interface, and a first plurality of programming instructions stored in the memory and operating on the processor, the programming instructions configured to;

provide a timestamping authority to generate timestamps for use throughout the system;

publish each timestamp as a zero-value block chain transaction using a distributed block chain network; and

generate hashes for use in encrypting interactions comprising voice recordings; and

a recording server computer comprising at least a second memory, a second processor, a second network interface, and a second plurality of programming instructions, the programming instructions configured to;

receive an interaction via a network comprising a voice communication;

record the interaction;

receive a timestamp and a hash from the timestamping authority;

verify the timestamp has not been tampered with by validating a block chain transaction associated with the received timestamp;

encrypt the recorded interaction with embedded timestamps using the received hash; and

store the encrypted recorded interaction with embedded timestamps in a secure database.
