A patent processed by the leading telecommunications company AT&T is directed to the home subscription management using distributed accounting technology. The race for patents of blockchain technology applications now also includes this proposal designed to provide a technological solution that protects information from customers subscribed to this services. This, by the authentication codes sent to mobile devices from a processor that protects bitcoin transactions information in distributed nodes. In this way, the company aims to patent both the operating device and the functions thereof.

It is proposed that subscribers of cable TV, to name one example, make its service operations with transactions in digital currency, confirming their identity in a device that registers and encrypts user information in the blockchain to subsequently verify.

In theory, the entire system would consist of a processor and a memory for storing instructions, including to manage sending data. This operation comprises a first nonce chain, an encrypted random number to be solved in the hashing, and a second nonce chain, which communicates with the user phone or laptop.

Data sent in the first nonce can be protected by a key associated with the mobile device. This key is obtained from the processor. In response, a confirmation is sent to the distributed database device. Both the identifier code as the key are stored in the database processor, like data in the second nonce, encrypted with a private key.

By this means, the user could make service payments using bitcoin in a public blockchain. In addition, the application of distributed nodes would allow to continue service if the system were to suffer an attack, and only would be directly affected those mobile devices under the coverage of the attacked processor.
