DrFirst.com Assigned Patent

DrFirst.com, Inc., Rockville, MD, has been assigned a patent (10,762,232) developed by Tang, Zilong, Rockville, MD, Chen, James F., Naples, FL, and Qian, Chen, Vienna, VA, for “self-consistent structures for secure transmission and temporary storage of sensitive data.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Implementations provide self-consistent, temporary, secure storage of information. An example system includes short-term memory storing a plurality of key records and a cache storing a plurality of data records. The key records and data records are locatable using participant identifiers. Each key record includes a nonce and each data record includes an encrypted portion. The key records are deleted periodically. The system also includes memory storing instructions that cause the system to receive query parameters that include first participant identifiers and to obtain a first nonce. The first nonce is associated with the first participant identifiers in the short-term memory. The instructions also cause the system to obtain data records associated with the first participant identifiers in the cache, to build an encryption key using the nonce and the first participant identifiers, and to decrypt the encrypted portion of the obtained data records using the encryption key.”

The patent application was filed on December 13, 2018 (16/219,420).
