摘要
PROBLEM TO BE SOLVED: To ensure normal functions, in plotting-out (output) of CAD data, and insert digital signature information or access control information to the data.;SOLUTION: In order to make apparel CAD data normally function, signature data must be separated when outputting it. Signature data is inserted to below the CAD data operated through a general monitor, and the two layers are locked. According to this, the CAD data part can be corrected and changed, while the signature data part can be held without being deleted. The CAD data can be normally plotted out (output) by releasing the lock only in the output thereof by use of an encryption technique which reacts only to an output command.;COPYRIGHT: (C)2010,JPO&INPIT
