Abstract:
This disclosure proposes integrating the architecture named Blockchain into our Printer’s transaction protocol. Such an addition will generate a unique, immutable transaction log.
Background:
Security leaks in printer receipts can be a problem and could be reduced. Improvements are identified in the following areas:
In the description below the word “request” refers to: searches, tracking orders, sales transactions, and the like.
- Request duplicity.
- Frauds in requests.
- Request fiscalization.
- Centralized transaction log requests search system.
Description:
For each request, a blockchain transaction will be generated. That blockchain transaction will be secured and logged into an architectural component that can be queried later for secured transaction log analysis. Such transactions will have the robustness and attack resistant characteristics of blockchain.
Basic data flow covered by disclosure:
1. Sale occurs, and POS system produces a request to be submitted to the blockchain journal.
2. Customer receipt is printed as usual, but request is sent to blockchain technology system.
3. Blockchain journal will take the request and validate it.
4. Secured request is stored in a transaction log requests search system.
Please see diagrams and additional details in technical disclosure format in attachments section.
