Abstract: Inter-device noise alerts may allow an electronic device, such as a smart phone or a smart watch, of one user to alert one or more electronic devices, such as smart phones, of one or more other users, that the noise level in a noise environment in which the electronic devices and the users are located may be unsafe for prolonged exposure. This can provide beneficial power savings by facilitating alerts from multiple devices without all of the multiple devices continuously monitoring the noise level. This also can be helpful for notifying the other users when, for example, the electronic devices of the other users are in a pocket, a bag, or another container and unable to detect the full noise level directly. The electronic devices of the other users can then provide alerts to the other users to don hearing protection or to leave the noise environment.

Abstract: The subject technology for maintaining differential privacy for database query results receives a query for a database that contains user data. The subject technology determines that the query is permitted for the database based at least in part on a privacy policy associated with the database. The subject technology determines that performing the query will not exceed a query budget for the database. The subject technology, when the query is permitted and performing the query will not exceed the query budget, performs the query on the database and receiving results from the query. The subject technology selects a differential privacy algorithm for the results based at least in part on a query type of the query. The subject technology applies the selected differential privacy algorithm to the results to generate differentially private results. The subject technology provides the differentially private results.
