Abstract
There is provided an information processing apparatus that generates an encrypted bit string in which a hash value calculated by using keyed hashing from a keyword for an information search is mapped into a bit string having a predetermined length, selects a predetermined number of bits from the encrypted bit string on the basis of a dynamically generated random number, inverts the predetermined number of selected bits, and sends the encrypted bit string and inverted-bit-number information to an external apparatus. The inverted-bit-number information indicates a number of bits inverted by a bit inverting unit.
