Smart Contract Trusted Execution Data Processing
Summary
USPTO published patent application US20260111605A1 filed by inventor Hyeong-Joon Kim on September 29, 2025 (Application No. 19344497), covering a method for processing personal information using a smart contract-based trusted execution environment on a blockchain. The system generates a TEE containing data processing code in response to a request via a smart contract, decrypts data from a generation device, processes it, and returns the result to the requesting device.
About this source
USPTO classification H04L covers transmission of digital information: network protocols, modulation schemes, wireless signal processing, coding, encryption in transit, and multiplexing. With 5G, 6G, and satellite internet driving new filings, H04L is one of the largest active patent classes. Every newly published application in H04L lands in this feed, around 215 a month. Applications publish 18 months after filing, so this feed reveals what MediaTek, Qualcomm, Ericsson, Samsung, Huawei, and dozens of smaller companies were working on in the prior year and a half. Watch this if you compete in networking hardware, advise telecoms on IP strategy, or scout acquisition targets in wireless infrastructure.
What changed
USPTO published patent application US20260111605A1, a smart contract-based method for processing personal information within a trusted execution environment (TEE) distributed on a blockchain. The application discloses generating a TEE with data processing code upon receiving a smart contract request, decrypting data from a generation device, processing the decrypted data, and providing the result to the requesting device. CPC classifications include G06F 21/6254, H04L 9/0891, and H04L 9/50.
Technology companies developing blockchain-based data processing systems, particularly those handling personal information in secure execution environments, should monitor this application for competitive intelligence on emerging smart contract privacy architectures. No compliance obligations are imposed by this publication.

METHOD AND SYSTEM FOR PROCESSING PERSONAL INFORMATION BY USING SMART CONTRACT-BASED TRUSTED EXECUTION ENVIRONMENT
Application US20260111605A1 Kind: A1 Apr 23, 2026
Inventors
Hyeong-Joon Kim
Abstract
A method for processing personal information by using a smart contract-based trusted execution environment according to an embodiment of the present invention comprises the steps in which: a data processing platform server generates a trusted execution environment including a data processing code, in response to a data processing request received from a data processing request device according to a smart contract distributed on a blockchain; the trusted execution environment decrypts first data acquired from a data generation device; the trusted execution environment processes the decrypted first data on the basis of the data processing code so as to generate a data processing result; and the trusted execution environment provides the data processing result to the data processing request device according to the smart contract.
