In order to prevent copying of protected data in a WIFI flash disk, in the embodiment of the present invention, a first visible partition is set on the flash memory chip 12, where when a data transmission channel exists between the flash memory control chip 11 and a host, the first visible partition is mounted, specifically, the host mounts the first visible partition under the control of the flash memory control chip 11, where the first visible partition is in a software write protection state (where data cannot be written and stored data cannot be deleted). The data in the first visible partition can only be written and deleted through the proprietary software interface, and the data in the first visible partition is always in an anti-copy state, namely, the data in the first visible partition cannot be copied. The proprietary software interface is a proprietary command defined in accordance with the USB transmission standard that is distinct from the USB standard command. The process of writing data into or deleting data from the first visible partition through the proprietary software interface is specifically: after the WIFI flash disk is connected with the proprietary software, the software write-protection state of the first visible partition is modified into a temporary write-in state, a user writes and deletes data in and from the first visible partition through the proprietary software, and after the proprietary software is disconnected with the WIFI flash disk, the first visible partition is modified into the software write-protection state from the temporary write-in state.

If not, the current operation is judged to be normal playing of the multimedia file, and no blocking is performed.
The proprietary software is a client integrating a proprietary software interface, a proprietary command protocol defined by a standard of quasi-guard USB transmission is provided, a special interface exists between the proprietary software and the WIFI flash disk, a special identifier is stored in the WIFI flash disk, the proprietary software identifies the WIFI flash disk through the special identifier, and the WIFI flash disk is determined to support the proprietary software. It should be noted that, in some embodiments, the proprietary software may also be the client 22, and the flash control chip 11 writes the multimedia file into the first visible partition of the flash chip 11.
In order to prevent copying of protected data in the WIFI flash disk and meet the convenience of the product, the embodiment of the present invention further sets a second visible partition for the flash memory chip 12, where the second visible partition is a common partition, and a user can read and write data in the second visible partition through the host and the WIFI module chip 14. When the flash memory control chip 11 judges that the currently mounted host is a computer system, a second visible partition is mounted; when the flash memory control chip 11 determines that the currently mounted host is the playing device system, the second visible partition is not mounted.
The software operation mode of the flash memory control chip 11 will be described below.
A first visible partition, a second visible partition, and a hidden partition are provided within the flash memory chip 12. The flash memory chip 12 has capacity sizes of 4G, 8G, 16G, 32G, 64G, 128G, and the like. The software operation mode of the flash memory control chip 11 is divided into: mass production mode, write mode, disk-out mode, and read mode.
The mass production mode is to read the capacity of the flash memory chip 12 and return to the mass production tool during production, and the mass production is calculated by percentage, the number, the size, the type and the attribute of the partitions are respectively written into the flash memory control chip 11, and the flash memory control chip 11 modifies the fat table of the first visible partition to statically allocate the size of the root directory area. And writing the starting address and the ending address of the allocated root directory area into the hidden partition for storage. The size of the allocated root directory area is greater than the number of first visible partition capacity storable files.
The write mode to the first visible partition is to send data to the flash memory control chip 11 in proprietary software installed by a computer, a mobile phone, a terminal processor, or the like. When receiving the instruction of writing the multimedia file, the flash memory control chip 11 reads the start address and the end address of the root directory area of the first visible partition from the hidden partition, writes serial attribute information such as the file name, the file attribute, the creation time and the like of the multimedia file into the root directory area, and writes the data information of the multimedia file into the first visible partition normally.
The second visible partition is a common visible partition, and can be written and read normally, so that the writing mode of the second visible partition is not repeated.
The outgoing mode is treated differently by detecting the mounting instruction code sent when the host mounts the flash memory control chip 11. The method comprises the following steps: when the flash memory control chip 11 is mounted on the windows computer system, a "Read Format Capacity" instruction (the instruction code is 23H) is first sent to the flash memory control chip 11, and then a "MODE SENSE (6)" instruction (the instruction code is 1 AH) is further sent, and at this time, the flash memory control chip 11 determines that the currently mounted system is the windows computer system. When the apple computer system mounts the flash memory chip 12, a "Request Sense" instruction (the instruction code is 03H) is first sent to the flash memory control chip 11, and then a "preset/Allow Medium Removal" instruction (the instruction code is 1 EH) is sent, at this time, the flash memory control chip 11 determines that the currently mounted system is an apple computer system. When the flash control chip 11 recognizes that the mounting system is a computer system, the first visible partition and the second visible partition are mounted, and if the mounting system is not a computer system, only the first visible partition is mounted.
When the flash control chip 11 recognizes that the mounting system is a computer system, the first visible partition and the second visible partition are mounted, and if the mounting system is not a computer system, the specific implementation of mounting only the first visible partition is as follows: when the flash memory control chip 11 recognizes that the mounted system is a computer system, the computer system then sends a "Test Unit Ready" instruction (instruction code 00H) for the first visible partition to the flash memory control chip 11, which means to inquire whether the first visible partition can be normally used, and the control chip replies a "Read" instruction (instruction code 00H) which means to be used; when the computer system sends a "Test Unit Ready" instruction (instruction code 00H) for the second visible partition to the flash memory control chip 11, the control chip replies with a "Ready" instruction (instruction code 00H) to inquire whether the second visible partition can be used normally. When the flash memory control chip 11 fails to detect the mounting of the computer system, it is determined that the current system is a playing device system, and when the playing device system sends a "Test Unit Ready" instruction (instruction code is 00H) for the first visible partition to the flash memory control chip 11, the first visible partition is intended to be used normally, and the control chip replies the "Ready" instruction (instruction code is 00H), the first visible partition is intended to be used normally; when the playback device system sends a "Test Unit Ready" instruction (instruction code 00H) for the second visible partition to the flash memory control chip 11, the playback device system inquires whether the second visible partition can be used normally, and the control chip returns a "Not Ready" instruction (instruction code 01H), which means that the playback device system cannot use the second visible partition. Thus, the first visible partition and the second visible partition can be mounted on the computer. And only the first visible partition will be mounted on the playback device.
And the reading mode is that after the host computer mounts the first visible partition, the root directory entry of the first visible partition is read and displayed. If the flash memory control chip 11 receives that the sector address of the first visible partition read by the host is between the starting address and the ending address of the root directory area recorded by the hidden partition, the host is considered to read the attribute information of the multimedia file of the first visible partition, and no processing is performed at this time, and the host reads normally. When the flash memory control chip 11 receives that the sector address of the first visible partition read by the host exceeds the end address of the root directory area recorded by the hidden partition, the host is considered to be the data information of the multimedia file of the first visible partition read, at this time, the flash memory control chip 11 calculates and records the change rule of the read rate within a period of time, if several graphs of the "copy" data are satisfied, it is determined that the current operation is to copy the multimedia file, and the flash memory control chip 11 immediately terminates the access of the host to the first visible partition. If not, the current operation is judged to be normal playing of the multimedia file, and no blocking is performed.
