Abstract

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.

Claims20

Dependent claims

A client system including a non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one processor, cause the client system to:

monitor data input by a user entering data into a data entry interface;
determine, via the monitoring, that the user has provided, via the data entry interface, data that uniquely identifies the user and a subject entity;
send, responsive to the determining, the data that uniquely identifies the user and the data that uniquely identifies the subject entity to a server;
receive, from the server, an indication that data records for the subject entity have been pre-fetched, wherein the server stores the pre-fetched data records for the subject entity in an encrypted portion of a data record, the encrypted portion being encrypted with an encryption key built from a nonce, the data that uniquely identifies the user and the data that uniquely identifies the subject entity;
and
responsive to receiving the indication, make available a control in the data entry interface, the control sending a report request to the server in response to selection of the control by the user, wherein the report request provides the data uniquely identifying the user and the subject entity and the server provides at least one of the pre-fetched data records in response to the report request.

3 more elements

A method comprising:

monitoring data input by a user entering data into a data entry interface for a data input event, the data input event occurring when the user has entered data in the data entry interface that uniquely identifies a subject entity;
sending, responsive to the data input event, data that uniquely identifies the user and the data that uniquely identifies the subject entity to a server;
receiving, from the server, an indication that a data record for the subject entity has been pre-fetched from a remote source, wherein the server stores the pre-fetched data record for the subject entity in an encrypted portion of a data record, the encrypted portion being encrypted with an encryption key built from a nonce, the data that uniquely identifies the user, and the data that uniquely identifies the subject entity;
and
responsive to receiving the indication, making available a control in the data entry interface, the control sending a report request to the server in response to selection of the control by the user, wherein the report request includes the data uniquely identifying the user and the data uniquely identifying the subject entity and the server provides, from the encrypted portion of the data record, the pre-fetched data record in response to the report request.
