In order to protect against unauthorized duplication of a library file, or the like, according to the present invention, an executable module is generated. The executable module is generated by generating, with decryption of an encrypted protective object, a protective object containing a procedure for terminating a process operation due to invalid relationship between a first protect code and a second protect code contained in the executable module, linking the resultant decrypted protective object with other object, and writing a protect code. Then, the decrypted protective object is deleted after linking with the other object.

Information processing apparatus, executable module generating method, and storage medium

Digital sound data is encrypted and recorded in a recording medium. Informationrequired for decoding the encrypted digital sound datais recorded in a programfor controlling the reproduction of sound data separately from the digital sound data. This can prevent PCM sound data recorded in the recording medium as a part of a content, from being reproduced separately from the content.

Recording medium having encrypted sound data recorded therein and information processor

Image processing means comprises image converting means for converting manipulation data inputted by a user with a manual controller or a mouse into an input pattern image, geometric shape judging means for determining a type of an input geometric shape indicated by the input pattern image based on a plurality of geometric shape judging criterion, image appearance displaying means for displaying a symbolic image corresponding to the type of the input geometric shape on the monitor, and image form determining means for determining a form of the symbolic image displayed on the monitor. The image form determining means comprises accuracy calculating means for determining accuracy of the input geometric shape based on the number of deviations from an allowable range of a judging criteria used in judgment for the determined type of the input geometric shape, and modification displaying means for modifying the form of the symbolic image displayed on the monitor based on the accuracy of the input geometric shape.
