In the realm of digital communication, STIR/SHAKEN represents a framework of interconnected standards, specifically Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted Information Using toKENs (SHAKEN). This framework is designed to validate the handoff of phone calls passing through the complex web of networks, enabling the receiving party's phone company to verify that a call is indeed from the number displayed on Caller ID.

​

However, not all networks are "Stir/Shaken Ready". Up to 75% of Stir/Shaken tokens are lost in transit and never reach their intended destination. There are also limitations due to GDPR, PII, legal aspects in different jurisdictions, and commercial interests of carriers.

​

CodeB has harnessed the power of blockchain technology to create Call Authentication protocols that address these limitations. While fully supporting Stir/Shaken, our technology transports the token "Out of Band" to ensure delivery. It also introduces cryptographic mechanisms for GDPR and PII compliance and to protect the commercial interests of the participating carriers.

​

Integration into existing systems is made straightforward and non-intrusive with CodeB's wide range of APIs such as CLI, REST, Web Services, and Web Sockets. An example of this is our "CodeB distributed SIP Proxy" which utilizes these APIs. You can also add support with minimal intervention into existing systems such as Asterisk.
