Abstract:
Provided are an apparatus and method for managing digital rights. An agent unit manages application programs to which DRM is to be applied and rights to contents processed by the application programs to which DRM is to be applied, and encrypt and decrypt the contents processed by the application programs. A rights management unit authenticates a user and manages a user right to the contents processed by the application programs. A kernel API hooking unit monitors input/output of a file through hooking kernel native APIs, requests the rights management unit to verify the user right to the contents to be processed, and requests the agent unit to encrypt or decrypt the contents when the user right to the contents to be processed is verified.

Abstract:
Provided are apparatus and method for selectively decrypting and transmitting DRM contents. A policy storing unit stores information on devices allowed for decryption of contents. A policy processing unit determines whether a target device, to which an encrypted content is transmitted, is a device allowed for decryption based on the information stored in the policy storing unit. A decryption unit decrypts the encrypted content. And a control unit controls the decryption unit to decrypt the encrypted content when the target device is the device allowed for decryption.
Abstract:
Provided is an erasable and programmable read only memory (EPROM) device in which a plasma enhanced oxide (PEOX) film covers an upper surface of a floating gate in a single poly one time programmable (OTP) cell and a method of manufacturing a semiconductor device having the same. The semiconductor device comprises a substrate having an OTP cell region, on which a floating gate is formed for making an OTP cell transistor, and a main chip region, on which a gate of a transistor is formed. A PEOX film is formed on the OTP cell region and the main chip region. The PEOX film covers the floating gate in a close state and covers the gate by a predetermined distance. A silicon oxy nitride (SiON) film Is interposed between the gate and the PEOX film in the main chip region.
