MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611111908 A) filed by Krishna Institute Of Engineering & Technology Kiet on September 17, 2026, for System And Method For Detecting And Attributing Bitcoin Mixing-Service Activity In Blockchain Transactions.
Inventors include Satyam; Sahil Singh; and Dr. Sonia Deshmukh.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A processor-executed system and method are disclosed for detecting and attributing the use of a mixing service within blockchain transaction data of a cryptocurrency, such as Bitcoin. Blockchain transaction data, including addresses, timestamps and values, is obtained and preprocessed to derive a relationship between addresses. A detection stage evaluates a plurality of mixer-signature criteria, including substantially equal-value outputs, elevated input-output fan-in and fan-out, temporal correlation, and transaction volume, in combination with a machine-learning model, to flag transactions exhibiting mixing-service behaviour that would evade any single criterion or model. Addresses associated with flagged transactions are clustered into a suspicious cluster, which an attribution stage links to a probable source entity or destination entity by reference to known entity data. A risk score is generated, and a report and fund-flow visualization are output for investigative and compliance use.
