==Use-cases== | |||
<!-- Use Case (if available) analyses how practical the protocol is--> | <!-- Use Case (if available) analyses how practical the protocol is--> | ||
===Classical database=== | |||
*Location-based services (to protect user location privacy). | |||
*Queries of electronic medical records (these require decades of information confidentiality; hence security against quantum computing based attacks is necessary) or medical test reports. | |||
*Music and film streaming (user does not want his/her tastes to be revealed to the server). | |||
*Pay-per-view services, where the user should pay a fee to access every single database element. | |||
Quantum (S)PIR protocols may be preferred to their classical counterparts to: | |||
*Achieve (S)PIR with better communication complexity: this is convenient in the case of large databases. | |||
*Achieve (S)PIR with better security: for instance, to secure classical channels as in [[#References|[5]]]. | |||
