ABSTRACT:
An object of the present invention is to prevent illegal use of data (digital contents), and a second object is to provide a method for processing data which ensures the collection of charges for secondary use of the data, a data reading method for reading the data processed by this processing method, and a recording medium storing programs implementing these methods.The method for processing data is such that in a method for processing a data body b which is encrypted and is decrypted on a decryption bit length basis, and thereby is reproduced, the data body b is encrypted, a part of this data body b with a bit length different from the decryption bit length is omitted, and the omitted part is closed so as to make the data continuous.
