An information processing device encodes a plurality of documents into a first plurality of encoded documents, respectively based on first encoding information in which a plurality of words and a plurality of first codes of a first code group are associated, words included in the plurality of documents and included in the first encoding information being encoded in the plurality of encoded documents. The information processing device performs frequency counts for each of a plurality of codes in the first encoded documents encoded in the first encoding. The information processing device encodes the plurality of first encoded documents into a plurality of second encoded documents respectively, utilizing a result of the frequency counts.

Encoding apparatus and encoding method

A non-transitory computer-readable recording medium stores therein an encoding program that causes a computer to execute a process including: first creating a plurality of pieces of encoded data that are obtained by encoding a plurality of files by using a specific encoding format; second creating a plurality of encoded blocks that are obtained by dividing combined encoded data, the combined encoded data being obtained by combining the plurality of pieces of the encoded data into blocks with a fixed length; and third creating an index associated with each of the plurality of the encoded blocks.

Encoding device, encoding method, decoding device, decoding method, and computer-readable recording medium

Information processing system includes a first certification device which executes a first temporary certification, creates a first temporary certificate, transmits it to an external device, carries out a first formal certification and creates the first formal certificate, a second certification device which executes a second temporary certification based on the first temporary certification, creates a second temporary certificate, transmits it to the external device, carries out a second formal certification and creates the second formal certificate, and a processing device which verifies a validity of the first formal certificate corresponding to the first temporary certificate and a validity of the second formal certificate corresponding to the second temporary certificate from the user, in response to a information processing request from the user and determines to execute the information processing corresponding to the information processing request based on the verification result.
