摘要： The present invention relates to a method and apparatus for authenticating various types of digital certificates by using a text embedding method. The execution of the present invention is divided into two case, one case including images in the certificate and another case not including the images in the certificate, according to the characteristics of the certificate. In the former case, a text embedding method is applied to images included in the certificate to embed a series of information text (a specific number of the certificate, and issuing organization, name of a person in charge, etc.) designated by a person who issues the certificate into the images. In the latter case, there is generated an image imperceptible to the human eve but having the same color as the ground color certificate.

摘要： Provided are a watermarking method and a watermarking apparatus for a mesh mode, which are applicable to a system which requires high precision, such as a rapid prototyping system. A reference coordinate system is set using 1-ring values of vertices of a 3D mesh model. The vertices are sorted based on the set reference coordinate system, and bit-information of the watermark consisting of bit string is, respectively, embedded into each of polygonal faces of the 3D mesh model in the sorted order.The present invention is advantageous in that the shape of the model is not deformed even when watermarked, and therefore the present invention is useful in a rapid prototyping system which requires high precision for the purpose of authenticating data integrity. The present invention can be also used for the purpose of marking contents without the need for storing, and for the purpose of information hiding.

摘要： Disclosed herein are a digital file encryption method, a digital file decryption method, a digital file processing apparatus, and an encryption format conversion apparatus. The digital file encryption method includes encrypting a file using specific encryption information, storing the encrypted file in a file system, and storing the encryption information in a stream provided by the file system. Accordingly, since file lengths before and after encryption are identical to each other, an application needs not to consider a header length or perform offset correction when using an encrypted file.
