In addition, the multimedia application software is stored in the read-only memory partition of the memory disk, so that the multimedia application software is in a read-only state, and the probability of virus attack of the multimedia application software is reduced. The multimedia data is stored in a hidden partition of the storage disk such that the multimedia data is invisible to the user and the multimedia data is in an encrypted state, which effectively prevents the multimedia data from being stolen. By the technical scheme, the problem that the media resources are maliciously copied and polluted by viruses is effectively prevented, and the security of media resource copyrights is improved.
In addition, in the embodiment of the application, when the multimedia data is required to be watched, the storage disk is connected with the electronic equipment, a network is not required, any application software is not required to be installed, and a complex installation process is not required, so that the problem that some operating systems are subjected to deep customization and restoration and conventional software cannot be installed and cured is solved, the flow of the user for watching the multimedia data is simplified, and the user experience is improved.
In one embodiment of the present application, a data interface, such as a universal serial bus (Universal Serial Bus, USB) interface, may be provided on the storage disk, and may be connected to a data line, where the data interface is used to connect to an electronic device in a wired manner. The storage disk is connected with the electronic equipment through the data line, and the plug and play of the storage disk is realized without additionally depending on other objects.
In one embodiment of the present application, a power supply and a wireless communication module may be provided on the storage disk. The power supply provides power for the wireless communication module, and the wireless communication module is used for the wireless connection of the storage disk and the electronic equipment.
In one embodiment of the present application, the data interface, power supply and wireless communication module may be provided on the storage disk simultaneously. Therefore, the electronic equipment and the storage disk can be connected in a wired mode or in a wireless mode, and the flexibility of connection of the electronic equipment and the storage disk is improved.
Based on the storage disk, the embodiment of the application also provides a multimedia processing method. Referring to fig. 2, fig. 2 is a schematic flow chart of a first method for multimedia processing according to an embodiment of the present application.

The description of the storage disk herein is relatively simple, with specific reference to the description of the storage disk above in FIG. 1 section. The multimedia processing method comprises the following steps.
In step 201, the multimedia application software stored in the read-only memory partition is run to generate a read path for the multimedia data stored in the hidden partition.
After the storage disk is connected with the electronic device, the electronic device reads the multimedia application software from the read-only memory partition of the storage disk and runs the multimedia application software. After the electronic device runs the multimedia application software, a path for reading the multimedia data stored in the hidden partition is generated. Here, the path of reading the multimedia data stored in the hidden partition may be simply referred to as a read path.
The above-mentioned reading path may be implemented through an SDK interface, or may be implemented in other manners, which is not specifically limited in the embodiment of the present application.
Step 202, reading the multimedia data stored in the hidden partition through the reading path.
In the embodiment of the application, after the electronic device generates the reading path, the multimedia data stored in the hidden partition is read through the reading path.
In one embodiment, the read path is implemented for an SDK interface. And the electronic equipment reads the multimedia data stored in the hidden partition into the memory of the electronic equipment in a streaming mode through the SDK interface. The streaming mode is used for transmitting the multimedia data, namely, a series of multimedia data are compressed and then sent in sections, and video and audio are transmitted in real time for viewing, so that the subsequent display of the multimedia data and the viewing of a user are facilitated.
And 203, decrypting the read multimedia data by utilizing a preset encryption algorithm and a preset key associated with the multimedia application software.

In order to facilitate the display of the subsequent multimedia data, when the electronic equipment reads the multimedia data, the electronic equipment decrypts the read multimedia data by utilizing a preset encryption algorithm and a preset key associated with the multimedia application software to obtain the plaintext data. For the data in the clear text, the electronic device can be directly displayed for the user to watch.
In one embodiment, a large amount of multimedia data is stored in the hidden partition, and if the multimedia data are read into the memory, a large amount of memory is occupied, so that normal operation of the electronic device is affected. In order to reduce occupied memory and reduce the influence on the operation of the electronic equipment, the electronic equipment reads the multimedia data into the memory of the electronic equipment after receiving a reading instruction for the multimedia data, and decrypts the read multimedia data by utilizing a preset encryption algorithm and a preset secret key associated with multimedia application software.
In one embodiment of the present application, after decrypting the read multimedia data, as shown in fig. 3, the above multimedia processing method may further include the following steps.
Step 204, a play command for the multimedia data is obtained.
In the embodiment of the present application, the play instruction may be input by the user into the electronic device. For example, after the electronic device reads the multimedia data, displaying a thumbnail of the multimedia data; and after receiving clicking operation of a user on a thumbnail of the multimedia data, generating a playing instruction for the multimedia data.
The playing instruction may be generated after the electronic device reads the multimedia data stored in the hidden partition into the memory.

In the embodiment of the application, after the electronic device acquires the playing instruction, the electronic device detects the multimedia data format, and runs the playing software matched with the multimedia data format, so that the multimedia data is rendered on the display through the playing software, and further the multimedia data is played.
In the embodiment of the application, the electronic device may determine the format of the multimedia data by detecting the file name suffix of the multimedia data. For example, file name suffixes include, but are not limited to txt, bmp, jpg, png, gif, rm, rmvb, mp, mov, mtv, dat, wmv, avi, mp3, wav, and the like. If the file name suffix of the multimedia data is txt, the format of the multimedia data can be determined to be an electronic book; if the file name suffix of the multimedia data is bmp, jpg, png or gif, determining that the format of the multimedia data is a picture book; if the file name suffix of the multimedia data is rm, rmvb, mpeg-4, mov, mtv, dat, wmv or avi, the format of the multimedia data can be determined to be video; if the file name of the multimedia data is sfb or amb, determining that the format of the multimedia data is an animation book; if the file name suffix of the multimedia data is mp3 or wav, it can be determined that the format of the multimedia data is audio.
The electronic device may also determine the multimedia data format by detecting information in a header of the multimedia data.
The embodiments of the present application are not limited to the manner in which the format of the multimedia data is detected.
In one embodiment of the present application, in order to provide the latest and most accurate multimedia data to the user, the embodiment of the present application further provides an information updating method, as shown in fig. 4, which may include the following steps.
In step 401, when the electronic device is detected to be in a networking state, management software of the multimedia application software is run to generate a management path.
In the embodiment of the application, the electronic device detects the current network state in real time. If a network exists currently, that is, the electronic device is in a networking state, the electronic device can download management software for installing multimedia application software, run the management software, and then generate a management path.
The management paths may be implemented through an SDK interface, or may be implemented in other manners, which are not specifically limited in the embodiments of the present application.
Step 402, obtaining new multimedia application software and new multimedia data from a background server of the multimedia application software.
When the electronic device is detected to be in a networking state, the electronic device can acquire new multimedia application software and new multimedia data from a background server of the multimedia application software.
In one embodiment, to save network resources, when it is detected that the electronic device is in a networking state, the electronic device may acquire version information of the multimedia application software in the storage disk and identification information of the multimedia data in the storage disk, and send the acquired information to a background server of the media application software.
The background server compares the acquired version information with locally stored version information of the multimedia application software. If the obtained version information is different from the version information of the locally stored multimedia application software, the background server issues the locally stored multimedia application software (i.e. new multimedia application software) to the electronic device. If the obtained version information is different from the version information of the locally stored multimedia application software, the background server does not perform other processing.
The background server compares the acquired identification information with the locally stored identification information of the multimedia data. If the identification information of the locally stored multimedia data is different from the acquired identification information, the background server issues the locally stored multimedia data (i.e. new multimedia data) corresponding to the different identification information to the electronic equipment. If the identification information of the locally stored multimedia data does not contain identification information different from the acquired identification information, the background server does not perform other processing.
The execution order of steps 401 and 402 is not limited in the embodiments of the present application.
Step 403, updating the multimedia application software stored in the read-only memory partition to new multimedia application software through the management path, encrypting the new multimedia data by using a preset encryption algorithm and a preset key, and updating the encrypted new multimedia data to the hidden partition.
After the electronic device obtains the new multimedia application software and the new multimedia data, the electronic device updates the multimedia application software stored in the read-only memory partition into the new multimedia application software through a management path (such as an SDK interface), encrypts the new multimedia data by using a preset encryption algorithm and a preset secret key, and updates the encrypted new multimedia data into the hidden partition.
In the embodiment of the application, the multimedia application software and the multimedia data in the storage disk are maintained and updated in real time through the management path, so that the latest and most accurate multimedia data are provided for users.
In addition, in the embodiment of the application, under the condition of a network, the multimedia application software and the multimedia data in the storage disk are maintained; under the condition of no network, the storage disk provides multimedia data for users, and the storage disk can be carried with, so that the flexibility of multimedia playing is improved.
In one embodiment of the present application, to maintain the copyright interests of the enterprise, a program for performing management operations on the multimedia application software may be included in the management software. The management operation includes one or more of activation, renewal, and reset.

In an embodiment of the present application, in order to improve security of a storage disk and maintain benefits of an enterprise, the embodiment of the present application further provides a multimedia processing method. As shown in fig. 5, the multimedia processing method may further include the following steps.
And 206, sending a heartbeat message to a background server of the multimedia application software, so that the background server detects whether the running state of the storage disk is normal according to the heartbeat message, and feeds back the detection result to the electronic equipment.
In the embodiment of the application, after the electronic device runs the multimedia application software, the heartbeat message can be sent to the background server of the multimedia application software at regular time. After receiving the heartbeat message, the background server detects whether the running state of the storage disk is normal or not, that is, whether the multimedia application software and the multimedia data stored in the storage disk are tampered or not based on the heartbeat message. If the operation state of the storage disk is detected to be normal, that is, if the multimedia application software and the multimedia data stored in the storage disk are detected not to be tampered, the electronic device does not perform other processing or feeds back a detection result to the electronic device, wherein the detection result indicates that the operation state of the storage disk is normal.
If the running state of the storage disk is detected to be abnormal, namely, the multimedia application software and the multimedia data stored in the storage disk are detected to be tampered, the electronic equipment feeds back the detection result to the electronic equipment. The detection result indicates that the operation state of the storage disk is abnormal.
And step 207, repairing the multimedia application software stored in the read-only storage partition and the multimedia data stored in the hidden partition when the detection result indicates that the running state of the storage disk is abnormal.
When the electronic equipment acquires a detection result and the detection result indicates that the running state of the storage disk is abnormal, the repair of the multimedia application software stored in the read-only storage partition and the repair of the multimedia data stored in the hidden partition are started.
In one embodiment of the present application, the electronic device may prohibit use of the storage disk when the detection result indicates that the operation state of the storage disk is abnormal. When the electronic equipment is detected to be in a networking state, the electronic equipment runs management software of the multimedia application software, and a management path is generated. The electronic equipment acquires the modification data of the multimedia application software and the multimedia data from a background server of the multimedia application software, and repairs the multimedia application software stored in the read-only storage partition and the multimedia data stored in the hidden partition through a management path according to the acquired modification data.
In the embodiment of the application, when the electronic device determines that the running state of the storage disk is abnormal, that is, when the multimedia application software and the multimedia data stored in the storage disk are tampered, the storage disk is repaired, and the storage disk cannot be used in the modifying process, that is, when the running state of the storage disk is abnormal, the storage disk is forbidden to be used, and the storage disk does not provide the multimedia data for the electronic device, so that the safety of the storage disk is improved, and the benefit of enterprises is maintained.
In one embodiment of the present application, to further increase the security of the storage disk, maintaining enterprise interests, the electronic device may periodically update the preset key when it is detected that the electronic device is in a networked state.
