Abstract: PURPOSE: A device and a method for playing image records are provided to store image data according to each unit which generates authentication codes, thereby suggesting image data matched with a condition when image data is suggested as evidence. CONSTITUTION: An image input unit(310) is connected to a camera. A storage unit(350) stores inputted image data. If a control command is inputted, a blocking controller(380) monitors the inputted control command. If the control command includes storage of image data except the inputted image data, the blocking controller blocks the control command. A controller(330) detects corresponding image data among the stored image data. The controller performs an operation corresponding to the inputted control command.

Abstract: A file security system uses a security class set by an access control module. The file security system includes a disk, a kernel memory and an encryption file system. The disk includes a key file in which an encryption key corresponding to the security class is stored and a file encoded by the encryption key. The encryption key stored in the disk is loaded into the kernel memory when the file security system starts operating. The encryption file system extracts an encryption key corresponding to a security class of a file that a user intends to read or store; decodes or encodes the file by using the extracted encryption key; and then provides the decoded file to the user or stores the encoded file in the disk.

Abstract: PURPOSE: An access control system and method is provided to secure a secrecy irrespective of an openness of a system OS, and to maintain a security against a system hacking by using a daemon determining an access authority and a security kernel performing a communication with the daemon via a character process device. CONSTITUTION: The method comprises steps of generating a packet to be requested via a system call module within a security kernel(S411), inserting the packet into a request list(S412), waking up a process sleeping at a read queue of a character process queue(S413), making the process sleep at a write process queue(S414), enabling a daemon, having an access authority and sleeping at the write queue of the character process device, to receive a request from a corresponding character process device and bring a corresponding packet from the request list(S421), checking if the corresponding packet exists at the request list(S422), if the corresponding packet exists at the request list, copying the brought packet at a user mode space(S423), if it does not, sleeping at the read queue(S424), if the security kernel wakes up a process sleeping at the read queue, instantly processing the request transmitted to the packet(S425), copying a response packet from the user space to a kernel space(S426), waking up the process sleeping at the write queue, and then executing the security kernel for receiving the result(S427), and giving back an execution result to a kernel module requesting an access control approval(S415).

Abstract: PURPOSE: A method for managing and controlling an entitlement in a chargeable broadcasting system for supporting various pay-view services is provided to classify a series by setting a proper theme ID and an event ID when a qualification managing message is created. CONSTITUTION: A key ID(21) is used for a cryptography of a plurality of information(22, 23, 24, 25, 26). Mask information(22) is a value for deciding an application range of a theme ID(23) and an event ID(24). The mask information(22) is identified with the sum of sizes of two fields. EXTM information(25) indicating an expiration time is used for deleting a qualification record exceeding to the time from a memory by an interior operation of a smart card. DUR information(26) is valid only in the case of a PPP service. The information from the mask information(22) to the DUR information(26) means a watching right of each member. If the corresponding qualification is valid, the information is stored in a card memory. In the case of a PPE(pay-per-event), the total value of the theme ID(TID)(23) and an event ID(EID)(24) becomes a valid program ID. In the case of a PPS(pay-per-series), the DUR information(26) is ignored and a bit calculation logical value of the mask information(22) and the theme ID(TID)(23) become a series. In the case of a PPP(pay-per-period), a user can watch from a starting time of watching of a chargeable program to a time passed for the DUR, and if the smart card receives a qualification managing message, one's expiration time is changed into a time adding the current time to the DUR, and thus the corresponding service is possible.
Abstract translation: 目的：提供一种用于管理和控制用于支付各种付费视图服务的可收费广播系统中的授权的方法，用于通过在创建资格管理消息时设置适当的主题ID和事件ID来对一系列进行分类。 构成：密钥ID（21）用于多个信息的加密（22,23,24,25,26）。 掩模信息（22）是用于决定主题ID（23）和事件ID（24）的应用范围的值。 掩模信息（22）用两个字段的大小的和来标识。 指示过期时间的EXTM信息（25）用于通过智能卡的内部操作来删除超过存储器的时间的资格记录。 DUR信息（26）仅在PPP服务的情况下有效。 从掩模信息（22）到DUR信息（26）的信息是指每个成员的观看权。 如果相应的资格有效，则信息存储在卡存储器中。 在PPE（按付费方式）的情况下，主题ID（TID）（23）和事件ID（EID）（24）的总值变为有效的程序ID。 在PPS（按系统付费）的情况下，DUR信息（26）被忽略，并且掩码信息（22）和主题ID（TID）（23）的位计算逻辑值变为一系列。 在PPP（每期付费）的情况下，用户可以从观看可收费节目的开始时间观看到DUR所经过的时间，并且如果智能卡接收到资格管理消息，则到期时间 改变为将当前时间添加到DUR的时间，因此相应的服务是可能的。
