Abstract: A malware detection facility is described. In a first computer system, the facility receives from a second computer system ciphertext obtained by subjecting plaintext file contents to homomorphic encryption. In the first computer system, the facility performs a malware detection operation directly on the received ciphertext.

Abstract: A facility for performing accurate and real-time privacy-preserving biometrics verification in a client-server environment is described. The facility receives the user's biometrics data such as face, voice, fingerprint, iris, gait, heart rate, etc. The facility then processes and applies various privacy-preserving techniques to this data to complete enrollment and authenticate users, including but not limited to: encrypting data with a key using homomorphic encryption techniques and sending the encryption to the server; the server computes directly on the encryption and returns the result, which is also encrypted under the same key, to the client; the client optionally performs post-processing and decryption (in any order) and obtains the enrollment or authentication result. The facility may repeat this process to increase security level, resulting in more than 1 round trip between the client and the server.

Abstract: An airflow control system for use in a vehicle is provided. The airflow control system includes a manifold and a recirculation duct in flow communication with the manifold. The recirculation duct includes a fan and a recirculation valve. The system additionally includes a ventilation duct coupled in flow communication with the recirculation duct between the fan and the recirculation valve. The ventilation duct is in flow communication with an ambient environment surrounding the vehicle and includes at least one ventilation valve.

Abstract: An exhaust system for an aircraft galley chiller is provided. The exhaust system includes a galley having a chiller that includes an inlet, a condenser fan inlet, a condenser fan outlet proximate to chiller inlet, and a first flow of air through the condenser, an air ventilation outlet conduit that includes a second flow of air therethrough, and an ejector pump. The ejector pump includes a first airflow inlet, a second airflow inlet and an airflow outlet, wherein the first airflow inlet is coupled in flow communication with the condenser fan outlet, the second inlet is coupled in flow communication with the air ventilation outlet conduit. As the second airflow increases, the first velocity increases in a direction away from the galley chiller facilitating a decrease in temperature at the condenser fan inlet.
