Patent for transmitting sensitive data using cryptographic records
Summary
USPTO published Patent Application US20260095440A1 for methods of communicating sensitive data using cryptographic records. The application, filed December 5, 2025 by inventors Mehdi Collinge, Omar Laazimani, and Alan Johnson, describes a system where elements of information are combined with time information to generate cryptographic records for secure data transmission. The patent covers filling data fields with time-stamped information and matching cryptographic records to verify data integrity.
What changed
USPTO published patent application US20260095440A1 describing cryptographic methods for transmitting sensitive data in restricted channels. The invention involves obtaining information elements, using time information to fill first places in a data field, generating a cryptographic record, and using that record to fill second places. Upon message reception, the data field can be resolved and the cryptographic record matched to verify information correctness.
Patent applications do not create compliance obligations. Technology companies developing secure communication systems should review the published claims to assess potential overlap with their existing or planned cryptographic implementations. This is informational only—no action or deadlines apply to third parties.

Abstract
Methods of communicating information relating to an event are described. Elements of information relating to the event and contained in a data field are obtained and used to determine a cryptographic record. First places in the data field are filled by the elements with time information. The cryptographic record is used to fill second places in the data record. On reception of a message including the data field, the data field can be resolved into the first places and the second places. The time information associated with the event can be determined and used to establish elements of information that were combined with the time information to fill the first places. The established elements can be used to calculate a cryptographic record, which can be matched against the cryptographic record from the second places to determine that the elements of information are correct.
