| 20110010756 | VIRTUAL APPLICATION PROGRAM SYSTEM, STORING DEVICE, METHOD FOR EXECUTING VIRTUAL APPLICATION PROGRAM AND METHOD FOR PROTECTING VIRTUAL ENVIRONMENT - The present invention relates to a virtual application program system, a storage device, a method of executing a virtual application program, and a method of protecting a virtual environment. The virtual application program system includes an execution control module for executing a virtual application program, and a virtual environment protection module loaded by the execution control module and configured to block non-permitted application programs from accessing a virtual environment accessed by the virtual application program. Accordingly, the virtual environment can be protected from a host application program, etc., and independency and security of a task using a virtual application program can be guaranteed. | 01-13-2011 |
| 20110010559 | METHOD FOR ENCRYPTING DIGITAL FILE, METHOD FOR DECRYPTING DIGITAL FILE, APPARATUS FOR PROCESSING DIGITAL FILE AND APPARATUS FOR CONVERTING ENCRYPTION FORMAT - 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. | 01-13-2011 |
| 20100299759 | DIGITAL INFORMATION SECURITY SYSTEM, KERNAL DRIVER APPARATUS AND DIGITAL INFORMATION SECURITY METHOD - Disclosed herein are a digital information security system, a kernel driver apparatus, and a digital information security method. The digital information security system includes a user module configured to operate in a user mode and to provide environment setting information comprising policy information about a use of digital information, and a kernel driver configured to operate in a kernel mode, to acquire information generated by an application of the user mode for the use of digital information, and to perform rights control regarding the use of digital information based on the acquired information and the policy information. Accordingly, the construction of a security system can be simplified, and the security of a security system can be improved. | 11-25-2010 |
| 20100266157 | METHOD FOR EMBEDDING WATERMARK INTO AN IMAGE AND DIGITAL VIDEO RECORDER USING SAID METHOD - The present invention relates to a method for embedding and detecting watermark wherein forgery/alternation of image can be identified and the location of forgery/alternation can be verified by embedding and detecting watermark into a digital image which is shot in real time. Watermark is generated by using a quantized coefficient after frequency transform used in the compression process. By embedding this into an image, image can be compressed simultaneously with embedding watermark. The present invention discloses a method for embedding robust watermark which embeds a random sequence circular shifted from an original pseudo random sequence by the distance d as watermark into an image. The present invention discloses a technology for generating and embedding watermark by using a DCT coefficient quantized during the process for MPEG compressing the image, wherein said watermark can be generated and embedded in a unit of macro blocks or slices. The present invention discloses a technology for generating and embedding watermark by using a wavelet coefficient quantized during the process for wavelet compressing the image. Further, the present invention discloses a digital video recorder recording the image which is shot in real time embedded with watermark in accordance with the above method for embedding watermark. | 10-21-2010 |
| 20100067807 | SYSTEM AND METHOD FOR VERIFICATING ELECTRIC DOCUMENT AND SYSTEM FOR PROVIDING ELECTRIC DOCUMENT SERVICE - A method and system for verifying an electronic document and a system for providing an electronic document service are provided. The system for verifying the electronic document includes: an image data acquisition unit acquiring an image of the electronic document by scanning the electronic document; a barcode detection unit detecting a barcode inserted into a predetermined position in the acquired image of the electronic document and acquiring first electronic document data; an image data conversion unit generating second electronic document data by converting a format of the acquired image of the electronic document into a format that can be compared with the first electronic document data; a falsification determination unit de | 03-18-2010 |
