Abstract

Abstract A record verification apparatus for comparing information of a block to be verified with verifying information so as to verify the former information. In the apparatus, information of the succeeding block is supplied to a first storage position of a memory to be compared with information of the preceding block having been previously verified, and information indicative of coincidence or non-coincidence therebetween is stored in a second storage position of the memory. Verifying information is compared with the information to be verified stored in the first storage position of the memory or with the coincidence or non-coincidence information stored in the second storage position of the memory to carry out the verification of the information to be verified.
