In the case of flash memory, the price is drastically lowered due to the development of production process technology and the increase in demand, and the digitalization of contents such as the quality and sound quality of digital movies and sound sources reaches the level of CD and DVD due to the development of various compression technologies. Is happening rapidly. However, currently used as a media medium for storing it, the physical storage time is limited and the use of cassette tape or CD and DVD, which is inconvenient compared to the MP3 player, which is widely used in the playback player. Since the storage medium has a strong analog element that is not suitable for the digitization of the content, recently popular MP3 uses an internal memory, a hard disk, or standard memory cards such as SD and MMC cards. Standard memory cards have the convenience of making it easy for a user to read / write / delete, but it is also true that copyrights such as records are severely damaged. In this respect, the new content media is based on inexpensive flash memory, and securely and non-replicatively records content data created in a variety of compressed formats, must not be erased after it has been recorded and sold, and is encrypted with a playback player. The data must be safe to play and must support both voice, video and text. Memory cards of various standards such as SD cards and memory sticks are being made, but considering the characteristics of the contents industry, play-only functions, copy protection functions, high price due to complex structure, and small size of the case make it difficult to characterize. There is a limit to replacing cassette tapes, CDs, and the like.

Therefore, the credit-sized read-only memory card (aka, “slim disk”) is implemented by optimizing the content that is patented by the present inventors so as to be able to compete with existing media in terms of reproduction-only function, copy protection function, and price. When a technique for forming a unique encryption key value using the characteristics (addresses) of a bad area generated during a flash memory manufacturing process is applied to the present invention, the present invention reads the information of such a bad area of a slim disk to obtain an encryption key value. Forming and automatically encrypting and decrypting devices that allow slim disks to be supported with minimal changes in a variety of devices that use existing flash memory, and methods and methods for implementing the methods The present invention relates to a recording medium which can be used.

That is, devices for reproducing audio and video are becoming more and more diverse, such as MP3 players / PMPs / PDAs / mobile phones / UMPCs / digital cameras / vehicle navigations, due to the remarkable development of information and communication technology. Since these devices use standard NAND flash memory, these devices are provided with an interface means for decrypting a flash memory based slim disk, so that the data of the slim disk can be automatically read and read in the same manner as the flash memory. If you can, you can easily extend the scope of your application while protecting the encryption methods and encryption key values that are most important to your content business.

That is, the present invention connects to the slim disk which records the encrypted content data, extracts the characteristic value of the bad area, and automatically decodes the specified content data corresponding to the flash memory control command of the external hardware device based on this. An interface device for automatically encrypting data that is encrypted and transferred to a control device according to a predetermined standard (flash memory interface method or various communication methods), and a computer recording the method and a program for realizing the method. The present invention relates to a readable recording medium.

The so-called Slim Disk, which has been patented by the present inventors, is uniquely calculated by a predetermined method that reads the bad area information uniquely generated for each memory like a human fingerprint due to random wafer properties and manufacturing process environment during the flash memory manufacturing process. It has a unique value, and SlimDisk has a big advantage that it is physically impossible to copy because it uses this as an encryption key value. As a technique for encrypting the content using the encryption key value, various methods (operation, logic, conversion, substitution, rotation, etc.) can be applied by the slim disk programmer, and the soft encryption key value can be added. Data can be protected from piracy. Since the encryption method is based on the physical encryption key value due to the characteristics of the bad area, it is possible to copy a disk from one slim disk to another slim disk, but since the physical encryption key values are different, playback is performed in a completely different form in the playback apparatus. Even if a pattern to be reproduced with respect to one physical encryption key value is found, it does not apply to other physical encryption key values, so it is meaningless. Of course, it is no exception that any encryption method can be decrypted when the principle of formation of all encryption key values and various methods of key value and encryption are disclosed. In this respect, the encryption methods applied as in the present invention are manufactured by using a semiconductor or the like to be automatically processed, thereby preventing any hacking and internal leakage that may occur, and easily supporting various external interface controllers provided by existing devices. To provide a slim disk support with minimal changes to existing devices.

Slim Disk can be made into a recording medium with a size and thickness similar to a credit card, and can be printed with various card designs according to contents, thereby maximizing the value of possession, satisfaction of ownership, portability and economy. In particular, video sources such as music videos have different capacities depending on the video compression method, but about 60 minutes of QVGA screen is provided in 128MB or less (available for educational purposes). In this case, it can be provided within 30MB. In this way, if a new read-only content recording medium and a playback-only audio / video device are made that can be used specifically for the recording medium, the low cost benefits of recording media and playback-only devices, and a variety of customized services (such as single recording) In addition to revitalizing the music video market, which has been stagnant due to the shortage of the music industry and playback players that sell music and contents, religious organizations and educational institutions put various contents into read-only memory cards according to their capacity. Application areas can be expanded, such as providing them together or providing them individually. In particular, the maximum playback time is 74 minutes for CDs and 60 minutes to 120 minutes for cassette tapes, but for MP3 (12M / hour is required for recording at 32kbps, up to 128kbps for music), about 80 hours for 1G bytes. Since it can be reproduced, a good educational tape (80 hours usually requires 80 cassette tapes) is enough for one slim disc.

The present invention has been proposed to solve the above-mentioned problems, and a slim disk containing encrypted content data in a form similar to a credit card, and various audio / video devices such as an MP3 player and a PMP specially encrypt an encryption process. Interface device that automatically encrypts / decrypts the encryption process by interfacing with the central processing unit of hardware through various interface methods such as flash memory even if not programmed, and a method and a computer recording a program for realizing the method. The purpose is to provide a readable recording medium.

Currently, in order to read and play encrypted contents of slim disks, various existing devices need to know all the encryption key values and encryption methods determined by the memory bad area of the slim disk, and soft encryption key values if necessary, and then connect and program hardware. If you go to an open platform in order to diversify terminals that support Slim Disk, all of these encryption methods should be disclosed. As public passwords are no longer ciphers, SlimDisk's encryption method, which is physically unique like fingerprints, is no exception. In this respect, various terminal developers can access the decrypted contents of the slim disk automatically through the semiconductor, the module, and the method of the present invention using a known general interface without accessing the encryption system, the method, and the key value of the slim disk. If you can, you can develop your own development platform with minimal modifications and offer a choice of flash memory interface, serial and parallel communication, or multiple communication methods such as USB and SDIO, as needed. Interface semiconductors, modules, and methods for converting such encryption schemes also receive original content in a predetermined interface method and are formatted by inspecting the state of the slim disk so that it can be used in a recording device that records contents on the slim disk. If not, the erase function may be initialized, the bad area information may be retrieved to calculate an encryption key value, and the original content may be encrypted to be written to the slim disk. A device (semiconductor, module) that supports only the read mode for converting the encrypted contents of the slim disk to its original value to an external device, and a device (semiconductor, module) that encrypts the recording device separately from the method, and the method It can also be configured independently. Most crypto devices are useless due to the incompleteness of the cryptosystem, the developer's back door, and the formalization pattern being easily recognized when creating numbers in all cases through sequence processing. If the device (semiconductor, module) and the method are provided, as in the case of the present invention, which is operated as a black box, the computer cannot determine the formalization pattern in the case of audio / video when only the backdoor of the developer is blocked. Can be completely protected from hacking since slim disks have different kit values. That is, even if the encryption pattern of one slim disk is found, this means that if the bad area information is the same slim disk (the probability that it does not exist, 1Gb class with 64k pages), the probability of equality if there are 20 bad pages 1 / (64k) ²⁰ , which is close to 0), and not equally on other slim disks.

As described above, if an interface means for decrypting a flash memory-based slim disk is provided and the data of the slim disk can be automatically read and read by the same method as the flash memory, it is important to protect the contents business. It is easy to extend the application range while protecting the encryption method and encryption key value. The present invention extracts the characteristic value of the bad area by connecting to the slim disk recording the encrypted content data as described above, and decrypts the specified content data in response to the flash memory control command of the external hardware device based on this. The present invention relates to an interface device for processing automatically encrypted data delivered to an external hardware device by a memory interface or various communication methods, and a method thereof. The memory used for the so-called "slim disk" patented by the inventors of the present invention is the flash memory is the most common because the recorded content must be maintained even if the power is lost among the various memory systems (DRAM, flash, SRAM, etc.). There are many different types of flash memory, but in the case of commonly sold semiconductor packages, 48 pins are standard for NAND flash types, and NOR flash is packaged with 48 to 88 pins. When it is changed to SD, MMC, CF, or memory stick type, which is a general memory card interface type, additional parts such as a flash card controller are added to increase the unit price. ) NAND flash memory can be at least 14 pins (I / O 8-pin, CLE, ALE, RE, WE, Power, GND) even if you do not use a separate flash card controller. Smart media cards made by Japan's “Toshiba” are the same in that they do not use a separate controller. However, since they must be supported for both read / write, there are as many as 18 pin contacts. In the case of recording contents such as slim disk and selling them for record, education, and religious purposes, only the reading function of the memory card is used, and the contents recorded on the memory card must be protected because the user must pay the cost and protect the purchased contents. In order to prevent random deletion and recording, in the case of smart media card, the WP (erite protect) signal among the signals that can be controlled externally is pulled down internally to be active to prevent writing and erasing in principle. Configuring is a big difference. This category also includes the provision of pins in read-only format, in memory card format, using disposable memory such as EEPROM or on-time programmbale EPROM (OTP), as well as various other non-erasable memories. Can be. As flash memory replaces most recording media, production is rapidly increasing. In the case of flash memory, memory cell sizes are gradually decreasing with increasing memory capacity, and a bad area (bit, byte, or block) inevitably occurs. If more than a certain standard (1G bit class, 20 bad blocks of the total 1024 blocks-Samsung Electronics data book) occurs, it is classified as a single product failure. In a standard memory card, bad data cannot be used because bad data is recorded because important data or files are recorded.However, when used as a read-only audio / video according to the present invention, even if a bad area appears, it may be compressed according to a compression method (wav file format). The sound and video are transformed in a very short time, so the user can hardly notice the difference. However, even if there is more than one bit, 128K byte blocks (for small blocks, 64Kbyte Unlike current flash memory that cannot use all of them, it is read-only, so it can be configured to use only bad part and not to use the rest of the normal area in the block. It can also be offered at a lower price. The device and the method of the present invention are connected to all the terminals of a slim disk made on the basis of the flash memory, and the encryption decryption method and logic, and additionally, by checking the bad area of the slim disk and calculating a unique encryption key value. Since the soft encryption key value is recorded, when an address is input from various external methods (read command in the case of NAND flash memory interface), the data of the corresponding address of the slim disk is read and the calculated disk It is configured to automatically convert and output the original data by the selection means, and only such a function can be independently semiconductorized, or a method such as modularization or a program to a control codec of an external memory interface of a semiconductor such as a compression codec and a CPU or a DSP. It may be provided as.

If you select the method, you can make it by applying it. NAND flash memory interface method is the most powerful in consideration of communication speed and price.

For reference, if a large number of external contact terminals are provided in the slim disks to which the present invention is applied, the number of terminals should be minimized because reliability is lowered and costs are increased. In the case of applying the most widely used and inexpensive flash memory to the present invention, at least 14 It is sufficient to configure the pins (I / O 8 pin, ALE, CLE, RE, WE, Power, GND), but if additional functions are to be supported later, R / B terminal and flash memory indicating the operation status of flash memory When not in use, a CE terminal may be included in the external contact connector to enter standby mode to reduce current consumption. In this case, the write / erase prohibit terminal (WP) is provided as a pull-down internally so that external devices cannot control it arbitrarily, but a 16-pin external contact pad is included in the slim disk for ease of writing content data at the factory. to provide. Although the names of each pin are defined based on the NAND flash memory as described above, most memory means have similar functions, so the category of the slim disk has minor operation differences on the timing chart provided by the name and the memory means.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, whereby those skilled in the art may easily implement the technical idea of the present invention. There will be. In addition, in describing the present invention, when it is determined that the detailed description of the known technology related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of an interface device for automatically processing an encryption process according to the present invention.

As shown in Fig. 1, the interface device (semiconductor, module) 2 according to the present invention retrieves the bad area information of the slim disk 3 and forms encryption key value logic 6 for forming a unique unique value. Logic 8 which optionally records the soft encryption key value, decryption logic 7 which automatically performs decryption using the bad area encryption key value and optionally the soft encryption key value, and a controller ( Address and data bus processing logic 9 which connects the address, data, and command between 1) and the slim disk.

In these devices (2), the terminals connected to the slim disk (3) are based on the standard NAND flash memory interface of 16 pins (I / O 8-pin, ALE, CLE, RE, WE, Power, GND, WP, CE). Means for connecting the internal device with decryption or encryption (7), encryption key value forming logics (6, 8), etc., to the control device 1 (when implemented on the same wafer, means the interface and communication end of the wafer). For example, when the NAND flash memory interface is applied, the control device 1 is implemented to read and write the slim disk 3 as one standard NAND flash memory without understanding the encryption process. In addition to the interface method connected to the control device 1, the device 2 of the present invention can be provided in various ways in the address and data processing logic (9). Such communication methods include USB, serial communication, parallel communication, SDIO. If you select standard communication method such as CF method or CF method, you can make it by applying it.When considering communication speed, price and applicability (most CPU, CODEC, DSP etc. have built-in flash ROM controller), NAND flash memory The interface method is the most powerful.

The slim disk 3 has an input / output contact terminal that connects 8 bits into which data and address data are input / output so as to contact a connector of a playback device, and a control signal contact terminal that connects several signal lines for read-only use. And the power supply terminal and ground terminal are installed, and the control signals that can be used for read only are the most commonly used NAND flash memory to support the read mode ALE (Address Latch Enable), CLE ( Command Latch Enable), RE (Read Enable) and WE (Write Enable) are implemented as a total of 16 terminals, and these terminals are connected to the corresponding contacts of the interface device 2, respectively. The control signal for controlling the memory may be configured differently according to the memory method, but is generally similar when the address bus and the data bus are used together like NAND flash memory. Among the standard memory cards, there is no product consisting of read-only (SD card can be put in write-protection mode by sliding the locking device on the side, but it is not suitable for the purpose because it can be arbitrarily operated by the user). Although there is memory such as OTP and EEPROM that can be used only once, it has a disadvantage of high pin count because it is difficult to make high capacity (up to 1Mbit), expensive, and separate address and data bus. The memory device is basically capable of writing and reading. Except that data is maintained when power is supplied, such as DRAM and SRAM, in the case of a memory device in which data is maintained even when power is lost, WP (Write protect) is used to erase and write data. It is designed to control the terminal as shown in the figure. When this terminal is active (set to high or low depending on the terminal design), write / erase is prohibited. The slim disk 3 is produced by fixing this terminal in an active state (pull-down state in the case of flash memory), and has advantages such as inventory management (content is not recorded in the card manufacturing factory, but content is stored in the memory card in the place of content management). The WP terminal may be separately installed on the card side to record the contents, and then, if necessary, marked with tape or printing to cover the portion.

For reference, NAND-type flash memory mainly used for slim disk has various capacities, and in principle, it is possible to design and produce inexpensively. The structure of flash memory is a cell of bits, and these bits gather to form a page, and the pages gather to form a block. In the case of a large block type flash memory, a page is composed of a total of (2048 + 64) bytes of 2048 bytes of main area and 64 bytes of free area (recording of the data state of the main area and the code area for error correction recovery). Since 64 pages are composed of one such block, the capacity of one block is (2048 + 64) x64 = (128K + 4K) bytes. In the case of small block flash memory, the page consists of 512 bytes of main area and 16 bytes of free area, which is composed of a total of (512 + 16) bytes. 16) x32 = (16K + 512) bytes. If the word is composed of 16-bit words instead of 8-bit units, each half is formed. In the case of NAND flash memory, the read / write mode is possible only in the unit of page because of the cell structure characteristics, and the erase function that needs to be performed before writing is only possible in the unit of block. <128K + 4K> bytes) will be unavailable. In case of 1G bit large block, 1024 blocks are provided.Because of this characteristic, up to 20 bad blocks are allowed in Samsung Electronics and Hynix, even 2% of the total blocks. And so on. In the flash memory, a spare area composed of the main area in page units includes bad block information, a logical sector number, a power failure status flag generated during writing, an error correction code value of the main area, and a logical sector number. Etc. are stored to ensure a certain degree of reliability and to recover from bit breaks occurring during use. That is, NAND flash memory may contain invalid blocks, but it should not store information in these blocks, the initial invalid blocks mean the original bad blocks tested before shipping and the invalid block markings 00H is written in each first page free area of the block, and additional bad blocks may occur during writing and erasing within the useful life (at least 10 years), resulting in 10% of the total capacity to prevent data loss. Set the others to a reserved area. If a bad block occurs during writing and erasing (very unlikely during reading), the original data is transferred to this storage area and recorded.However, if no additional bad block occurs during use, the storage area is not used and is discarded. Current devices that use flash memory to respond to user claims caused by data loss are mandatory. In other words, if an error occurs during writing or erasing, the block is marked as a bad block and replaced with a block in the storage area. However, when an error occurs during reading, the error correction code is reconfirmed and corrected. Compared to existing devices that use all of these read / write / erase functions, if content data is written to the flash memory once and then used as read-only, the block unit mode such as the erase function is used only in page unit mode. However, even if a bad bit occurs, memory space can be operated in units of bad pages rather than a bad block.In the case of a large block, when a bad bit occurs, all of the (128K + 4K) bytes cannot be used at present. In read-only mode, there is a big advantage (validating 98.5%) that only discards (2K + 64) bytes. Devices that use both read / write / erase functions allocate about 10% of the total capacity to the reserved area to cope with bad bits that may occur during use. When used in read mode, the probability of bad bits is generated. This extremely small advantage means that you do not have to allocate storage space separately, so you can use all of the given memory capacity. In addition, in read-only mode, a separate flash memory file management program (FAT) is not needed at the device (device) stage. When implemented in more detail, the bad area is not used but other normal areas (bad bits of the 2K byte page area) It can also be implemented in such a way that if one occurs, only one byte is valid and the 1999 byte is valid. In the case of a bad disk generated by the present inventors, when a bad bit is generated during initialization, a method in which a block to which the bit belongs is made into a bad block, and when a bad block is made in the process of erasing and writing, a method of writing a slim disk into a reserved block area is currently used. As described above, since the flash memory and the memory card used for content recording are only recorded once at the time of manufacture, a block with bad bits is determined by bad bit information found during initialization (formatting). Flash memory control characterized in that it is implemented to write data sequentially to the next normal block, so that there is no storage block area that is not needed if the bad block does not occur during use, and utilizes all the given memory space. The first advantage is that the method can be applied. In addition, since the flash memory and the memory card used for content recording in the slim disk are only written once at the time of manufacture and are configured as read-only so as not to use the basic function of erasing by block of flash memory, the initialization (formatting) is performed. Pages with bad bits are marked as bad pages or written in the header file area that stores the bad page addresses and write data sequentially to the next normal page. As a second advantage, it is possible to apply the flash memory control method that uses the space except the bad page. In addition, the address of the bad area (1 bit, 4 bit, 8 bit, 16 bit, etc.) found during the initial inspection is recorded in the header file area that records the characteristics of the flash memory in the slim disk, and the data of the flash memory is stored. When recording the data in the area and reaching the position where the bad area is found based on the header file data, the area is skipped and the data to be recorded in the bad area is subsequently recorded at the next position. Flash memory is controlled to skip the address when the address of the bad area is reached and to read the data of the later area, so that all the normal areas except the bad area are used in the bad block. As a third advantage, it can be applied. In addition, the addresses of the bad areas (1 bit, 4 bits, 8 bits, 16 bits, etc.) found during the initial inspection are recorded in the header file area for recording the characteristics of the flash memory in the slim disk, and the data area of the flash memory. Ignores the bad area and writes the data sequentially, and at the location where the bad area is found, it records the true data value corresponding to the corresponding address in the header file area, and reaches the address of the bad area when the reader reads the flash memory. If so, it skips and replaces it with a true data value corresponding to the corresponding address in the header file area, and applies the flash memory control method, which uses all remaining normal areas except the bad area in the bad block. The fourth advantage is presented.

2A and 2B are flowcharts of an embodiment of an interface method for automatically processing an encryption process according to the present invention, and a read mode and a write mode will be described, respectively.

In the method of the present invention, in order to implement a read mode, the hardware of the interface device (semiconductor and module) to be connected to the contact terminal of the slim disk, respectively, to implement the hardware, to check, read, write, Enables erasing and status checking, first checks the bad area of the flash memory in the slim disk, forms a specific encryption key value by the method (password # 1) set up on the basis of this, and based on the encryption key value, When the address is input, the data is read by assigning the address to the slim disk, and the original data is applied by applying the set decryption method (password # 2) and optionally the soft encryption key value (password # 3). Decodes the data and converts the data into a predetermined format through the address and data processing logic section 9 to the control device. To be delivered. This process is repeated while increasing the address until the control device completes the read mode.

As described above, a reading function is basically provided, but a method of encrypting and recording data on a slim disc is as follows. This means that the current slim discs are prohibited from recording data by individuals, but when the verification of contents protection is done, it is possible to download the data in connection with a computer and encrypt it and write it to the slim disc. Downloading and encrypting and recording it through the method of the present invention and sending the bad area information of the slim disc to a separate authentication center, the encrypted data of the content selected by the user is downloaded and the method of the present invention simply There is a way to write sequentially. The latter method is judged to be the most advantageous method because only encrypted content data is exposed even if hacking is performed, through which a blank slim disc is inserted into the playback device to authenticate the encrypted content through a separate authentication center. Calculation) and payment to provide convenience for download and use. This can be implemented in the form of a kiosk vending machine and a slim disk recording device used in factories, which are authenticated by such a network and download encrypted contents and simply record them. In this case, there is a method in which the authentication center sends only the information of the bad area and processes the encryption key value in the authentication center and calculates and sends the encryption key value. However, the authentication center is electronically configured to prevent hacking about the encryption key value generation pattern method. desirable. In the first mode of writing mode, the original contents are received from a separate control device (content database, authentication center, etc.) and encrypted (encrypted) and recorded on the slim disk. The hardware is implemented to be connected to each of the slim disk contact terminals, so that the flash memory inside the slim disk can be inspected, read, written, erased and checked, and the bad area of the flash memory in the slim disk is first examined. Based on this, a specific encryption key value is formed by the method (password # 1), and when an address and data desired to be written by an external control device are input based on the encryption key value, the address to be written to the slim disk is designated, and the data is set. Encryption method (password # 2) and optionally soft password Encrypts data by applying key value (password # 3) to form encrypted data to be used in the flash memory of the slim disk, converts it into a predetermined format through the address and data processing logic unit 9, and transmits it to the slim disk. To do that. This process is repeated while increasing the address until the controller completes the write mode. In the second mode of writing mode, a function that receives encrypted contents for the slim disk from a separate control device (content database, authentication center, etc.) and simply writes it to the slim disk is provided. The hardware is implemented to be connected to each of the slim disk contact terminals, so that the flash memory inside the slim disk can be inspected, read, written, erased and checked, and the bad area of the flash memory in the slim disk is first examined. When the information of the bad area is sent to a separate control device (content database, authentication center, etc.), the control device forms a specific encryption key value by the method (password # 1) set based on this, and the user selects it based on the encryption key value. Select the encryption method (password # 2) and the data of the content By applying the soft encryption key value (password # 3) to encrypt the data, and passing the encrypted data along with the address to the semiconductor and module for the interface to form encrypted data to be written to the flash memory of the slim disk, and The address and data processing logic unit 9 converts the data into a predetermined format and transmits the data to the slim disk. This process is repeated while increasing the address until the controller completes the write mode. At this time, instead of sending the information of the bad area to a separate control device (content database, authentication center, etc.), there may be a method of calculating an encryption key value (password # 1) in the interface method of the present invention and sending it.

First, a method of downloading unencrypted content data and encrypting and recording it through the apparatus and the method of the present invention and secondly, sending the bad area information of the slim disk to a separate authentication server 11 based on the content operation server. (11), if the user transmits the encrypted data of the content selected by the user, there is a method of simply writing the data on the slim disk sequentially in the apparatus and the method of the present invention. Here, the authentication server 11 includes only the bad area information and the encryption key value is processed by the authentication server 11 by a predetermined algorithm, and the encryption key value is calculated and sent by the controller 13.

It is provided as a function to record on the hardware. The interface of semiconductor and module for interface are implemented in hardware so as to be connected to the contact terminals of the slim disk, so that the flash memory inside the slim disk can be inspected, read, written, erased, and status checked. Firstly, the bad area of the flash memory in the slim disk is examined, and a specific encryption key value is formed by the method (password # 1) set based on this, and linked with the computer and the network connection device 12 based on the encryption key value.

In the second mode of writing mode, the encrypted content data is downloaded to the computer and the network connection device 12 through the content operation server 10 and the authentication server 11, and is provided as a function of simply recording on the slim disk. By implementing the interface of the interface semiconductor and module to the contact terminals of the slim disk, the hardware is implemented so that the flash memory inside the slim disk can be inspected, read, written, erased and checked.

Repeat the above process. At this time, the encryption key value is formed in the authentication server 11 instead of forming a specific encryption key value and sending it to the authentication server 11 by examining the bad area of the flash memory in the slim disk and setting the specific encryption key value based on the method (password # 1). The control device 13 may be implemented to simply transmit information of the bad area.
