Private Information Retrieval (PIR)

Private Information Retrieval (PIR) is a technology that allows users to access specific data from a server without revealing which item they are interested in. Think of it like searching for a book in a library without the librarian knowing which book you wanted. PIR ensures your query remains private, protecting your interests and privacy, especially when retrieving sensitive information or browsing confidential content. This is achieved through cryptographic techniques or distributed systems that hide your specific request while still enabling accurate data retrieval.
