A CPIR (Computationally Private Information Retrieval) protocol is similar to a PIR protocol: the receiver retrieves an element chosen by him from the sender's database, so that the sender obtains no knowledge about which element was transferred. [8] The only difference is that privacy is safeguarded against a polynomially bounded sender. [14]

Automated information retrieval systems are used to reduce what has been called information overload. An IR system is a ...

The right of access, also referred to as right to access and (data) subject access, is one of the most fundamental rights in data protection laws around the world. For instance, the United States, Singapore, Brazil, and countries in Europe have all developed laws that regulate access to personal data as privacy protection.
Indexing and classification methods to assist with information retrieval have a long history dating back to the earliest libraries and collections however systematic evaluation of their effectiveness began in earnest in the 1950s with the rapid expansion in research production across military, government and education and the introduction of computerised catalogues.
