Two data units are selected from main information, such as MIDI data, into which additional information is to be incorporated, to calculate a difference between respective values of the two data units. A particular data segment to be incorporated into one of the MIDI data units is selected from a group of data of additional information. The size of the data segment to be incorporated into one of the data units may be either one bit or two or more bits. Substitute data to replace the content of one MIDI data unit is generated on the basis of a predetermined function using, as variables, the data-related value and a value of the particular data segment, and the content of the data unit corresponding to a predetermined one of the two MIDI data units is replaced by the generated substitute data. Thus, through such an electronic watermarking technique, any desired additional information can be incorporated into the MIDI data without changing the MIDI data format. In another implementation, data of encoding information, representative of an encoding procedure, are incorporated dispersedly into particular data units belonging to a predetermined first data group of the main information, and data belonging to a predetermined second data group of the main information are encoded by the encoding procedure represented by the encoding information.

An original signature can be verified even if a signed image data is properly altered in its portion. The digital image data is divided into a plurality of configurational elements, and each of the feature values of the elements are calculated, so that the signature is created by combining the feature values. In case the configurational elements are to be deleted, they are substituted by substitutive data, and only the feature values are stored. The verification is created by using the stored feature values as the substituted elements and by using the calculated feature values as the remaining elements, so that the signature is verified with the signature attached to the digital image data.

A reader and writer access a ring buffer without using a locking mechanism, thereby avoiding any delays attendant to using a locking mechanism when performing read operations to supply the reader with data from the ring buffer. Other measures are used to reduce delayed performance of read operations.

Any of several information processing techniques may be used in various information storage and transmission applications to prevent the occurrence of certain "forbidden" bit patterns. According to an encoding technique, a reversible coding process is used to generate an encoded representation of an information stream that cannot contain any forbidden data patterns. This may be accomplished by partitioning the information stream into segments and encoding each segment according to a respective encoding key that is selected such that the results of the coding process cannot contain a forbidden data pattern. According to one substitution technique, all occurrences of forbidden data patterns are replaced with permissible data patterns that do not otherwise occur in the information stream. This may be accomplished by partitioning the information stream into segments, identifying an unused data pattern in a respective segment, and carrying out the replacement of all occurrences of the forbidden data pattern in that segment. According to another substitution technique, all occurrences of a forbidden data pattern are replaced by any permissible data pattern. This may be accomplished by partitioning the information stream into segments, identifying occurrences of the substitution data pattern and the forbidden data pattern in a respective segment, constructing a flag for each occurrence, and replacing all occurrences of the forbidden data pattern in that segment with the substitution data pattern. Decoding keys, substitution data patterns, substitution flags or any other information needed to recover the original information is assembled with the modified information in a form that does not equal the forbidden data pattern.
