Abstract: A network environment is described for securely storing data for anonymized contact tracing while an application is executing in a background state. An application can receive a message containing data while the application is executing in a background state. The data is encrypted using a public key. Next, the application can store the encrypted data in an alternate data store. Subsequently, and upon user authentication, the application can decrypt a secure data store decrypt the encrypted data. The application can then store the decrypted data in the decrypted secure data store. The application can receive user input indicating a positive test result for a communicable disease with an incubation period, and anonymously upload the data stripped of any uniquely identifying information.

Abstract: Disclosed are various embodiments for securely storing data while an application is executing in a background state. An application can receive a message containing data, wherein the message is received by the application while the application is executing in a background state. The application can then encrypt the data in the message using a public key accessible to the application to generate encrypted data. Next, the application can store the encrypted data in an alternate data store. Subsequently, the application can authenticate a user of the computing device and switch execution to the foreground in response. Then, the application can decrypt a secure data store using an application specific encryption key. Next, the application can decrypt the encrypted data using a respective private key for the public key to generate decrypted data. The application can then store the decrypted data in the decrypted secure data store.
