As shown in the figure, it is used to realize data transmission between a smart mobile hard disk and an electronic device. The method for using the smart mobile hard disk includes:

[0036] 201. Acquire data to be transmitted; the data to be transmitted is located in the smart mobile hard disk or the electronic device.

[0037] Among them, in the embodiment of the present application, the data to be transmitted may include at least one of the following: video, image, text, compressed package, script file, application program, etc., which are not limited here.

[0038] In the embodiment of the present application, the data to be transmitted may be located in a smart mobile hard disk, and the data to be transmitted may be located from the smart mobile hard disk to the electronic device.

[0039] 202. Establish m data transmission channels between the smart mobile hard disk and the electronic device, where m is an integer greater than 1.

[0040] In the embodiment of the present application, the data transmission channel may include at least one of the following: a wired data transmission channel, a wireless data transmission channel, a hybrid data transmission channel, etc., which are not limited here. A wired data transmission channel is a data transmission channel established directly using a data line, a wireless data transmission channel is a data transmission channel implemented using wireless data transmission technology, and a hybrid data transmission channel is a data transmission channel implemented by both wireless data transmission technology and wired data transmission technology.

In this way, the data transmission channel obtained is a hybrid data transmission channel.

[0042] 203. Obtain attribute information of each of the m data transmission channels to obtain m pieces of attribute information.

[0043] In an embodiment of the present application, the attribute information may include at least one of the following: channel type, channel bandwidth, channel data transmission rate, channel distortion rate, channel packet loss rate, channel signal-to-noise ratio, etc., which are not limited here.

[0044] In the embodiment of the present application, the attribute information of each of the m data transmission channels can be obtained to obtain m attribute information, and the attribute information can be used to implement channel evaluation.

[0045] 204. Evaluate the data transmission rates of the m data transmission channels according to the m pieces of attribute information to obtain m data transmission rates.

[0046] In an embodiment of the present application, attribute information related to the data transmission rate can be obtained from each attribute information. The attribute information related to the data transmission rate can be preset or system default, and can be obtained based on experience. The attribute information related to the data transmission rate is then used to evaluate the data transmission rate of each data transmission channel to obtain corresponding evaluation results. These evaluation results are then weighted to obtain the data transmission rate of each data transmission channel.

[0047] 205. Evaluate security evaluation values ​​of the m data transmission channels according to the m attribute information to obtain m security evaluation values.

[0048] In an embodiment of the present application, attribute information related to security evaluation can be obtained from each attribute information. The attribute information related to security evaluation can be preset or system default, and can be obtained based on experience. The attribute information related to security evaluation is then used to evaluate the security evaluation value of each data transmission channel to obtain corresponding evaluation results. These evaluation results are then weighted to obtain the security evaluation value of each data transmission channel.

[0049] 206. Transmit the data to be transmitted according to the m data transmission rates and the m security evaluation values.

[0050] In this magical embodiment, m data transmission rates and m security evaluation values ​​determine the performance of each data transmission channel. Furthermore, the data to be transmitted can be dynamically processed based on the performance of each data transmission channel to achieve efficient and secure data transmission, which helps to improve the data transmission efficiency of the smart mobile hard disk in the case of large-scale data transmission.

[0051] Optionally, the m security evaluation values ​​include a maximum value and a second maximum value; the above step 206, transmitting the data to be transmitted according to the m attribute information and the m data transmission rates, includes:

[0052] Dividing the data to be transmitted into m parts based on the m data transmission rates to obtain m data blocks; each data transmission channel corresponds to a data block; each data block includes at least one data, and each data corresponds to a data index;

[0053] Generate an index list based on the data index of each data in the data to be transmitted;

[0054] Determine the encryption information corresponding to each of the m data transmission channels according to the m security evaluation values ​​to obtain m encryption information;

[0055] Sending the m encrypted information to the other party through the data transmission channel corresponding to the maximum value;

[0056] Sending the index list to the other party through the data transmission channel corresponding to the second largest value;

[0057] Processing the m data blocks according to the m encryption information to obtain m target data blocks;

[0058] The m target data blocks are sent to the other party, so that the other party can decrypt the m target data blocks using the m encryption information to restore the m data blocks, and splice the data in the m data blocks into the data to be transmitted based on the index list.

[0059] Among them, the encryption information may include at least one of the following: whether to encrypt, encryption location, partial or full encryption, encryption algorithm, encryption algorithm control parameters of the encryption algorithm, etc., which are not limited here. The encryption algorithm control parameters of the encryption algorithm are used to control the algorithm complexity, encryption efficiency, etc. of the encryption algorithm.

[0060] In an embodiment of the present application, the data to be transmitted can be divided into m parts based on m data transmission rates to obtain m data blocks, wherein the faster the data transmission rate, the larger the memory size of the data block, and conversely, the lower the data transmission rate, the smaller the memory size of the database, wherein each data transmission channel corresponds to a data block; each data block includes at least one data, and each data corresponds to a data index, which identifies the data location and is used to smoothly splice the data into complete data after transmission to the other party.

[0061] Furthermore, an index list can be generated based on the data index of each data in the data to be transmitted, and the index list can store the data indexes of all data so that after being transmitted to the other party, it can be smoothly spliced ​​into complete data. In a specific implementation, a mapping relationship between a preset security evaluation value and encryption information can be pre-stored, and then, based on the mapping relationship, the encryption information of each data transmission channel in the m data transmission channels corresponding to each security evaluation value in the m security evaluation values ​​can be determined to obtain m encryption information.

[0062] Furthermore, the m encrypted information can be sent to the other party through the data transmission channel corresponding to the maximum value, and the index list can be sent to the other party through the data transmission channel corresponding to the second largest value. That is, the index list and encrypted information can be transmitted to the other party respectively using the two most secure data transmission channels, which not only ensures data transmission efficiency but also security. Separate transmission further ensures security.

[0063] Next, the corresponding data blocks in the m data blocks can be processed according to the m encrypted information to obtain m target data blocks. That is, since the encryption information is known, the decryption information is also easily known, that is, the decryption operation can be performed using the decryption information corresponding to the m encrypted information, and then the m target data blocks are sent to the other party, so that the other party can decrypt the m target data blocks using the m encrypted information to restore the m data blocks, and the data in the m data blocks can be spliced ​​into the data to be transmitted based on the index list. In this way, not only the security of data transmission can be guaranteed, but also it can be smoothly restored after being split, which greatly improves the data transmission efficiency.

[0064] Optionally, the above step of determining the encryption information corresponding to each of the m data transmission channels according to the m security evaluation values ​​to obtain the m encryption information may include the following steps:

[0065] Determine the encryption algorithm corresponding to each of the m security evaluation values ​​to obtain m encryption algorithms;

[0066] Obtaining encryption algorithm control parameters corresponding to each of the m encryption algorithms to obtain m default encryption algorithm control parameters;

[0067] Estimate the encryption time consumption of the m encryption algorithms and the corresponding data blocks to obtain m encryption time consumptions;

[0068] Determine the average duration of the m encryption times;

[0069] Determine the deviation between the m encryption time consumptions and the average time consumption to obtain m deviations;

[0070] Determine the optimization parameters corresponding to the m deviations to obtain m optimization parameters;

[0071] Optimizing the m default encryption algorithm control parameters according to the m optimization parameters to obtain m encryption algorithm control parameters;

[0072] The m encryption information are determined according to the m encryption algorithms and the m encryption algorithm control parameters.

[0073] In an embodiment of the present application, a mapping relationship between a preset security evaluation value and an encryption algorithm can be pre-stored, and then, the encryption algorithm corresponding to each of the m security evaluation values ​​can be determined based on the mapping relationship to obtain m encryption algorithms, that is, considering the security of different data transmission channels, the corresponding encryption algorithms are configured, wherein the lower the security, the more complex the encryption algorithm, and the higher the security, the simpler the encryption algorithm, or even no encryption.

[0074] Among them, different encryption algorithms correspond to different encryption algorithm control parameters. Each encryption algorithm can pre-set default encryption algorithm control parameters. Then, the encryption algorithm control parameters corresponding to each of the m encryption algorithms can be obtained to obtain m default encryption algorithm control parameters. Since the encryption algorithm, the default encryption algorithm control parameters and the data block are all known, the encryption time of the m encryption algorithms and the corresponding data blocks can be estimated to obtain m encryption time costs. The average duration of the m encryption time costs can also be determined. Then, the deviation between the m encryption time costs and the average time cost can be determined to obtain m deviations. Deviation = (encryption time - average time cost) / average time cost.

[0075] Furthermore, the mapping relationship between the preset deviation degree and the optimization parameter can be pre-stored, and then, the optimization parameter corresponding to the m deviation degrees can be determined based on the mapping relationship to obtain m optimization parameters, and the m default encryption algorithm control parameters are optimized according to the m optimization parameters to obtain m encryption algorithm control parameters. For example, the optimized encryption algorithm control parameter = (1 + optimization parameter) * default encryption algorithm control parameter, and the value range of the optimization parameter can be -0.1 to 0.1. Then, it can be ensured that the encryption time difference of each data transmission channel is within a preset range. The preset range can be pre-set or system default, and then m encryption information is determined based on the m encryption algorithms and the m encryption algorithm control parameters. In this way, the encryption algorithm control parameters of each encryption algorithm can be feedback adjusted so that the m data transmission channels can achieve synchronous data transmission, which can not only ensure the security of data transmission, but also greatly improve the data transmission efficiency.

[0076] Optionally, the following steps may also be included:

[0077] Determine the data memory size of the data to be transmitted;

[0078] When the data memory size is greater than a first preset threshold, the step of establishing m data transmission channels between the smart mobile hard disk and the electronic device is performed.

[0079] The first preset threshold may be preset or set by system default.

[0080] In a specific implementation, the data memory size of the data to be transmitted can be determined. When the data memory size is greater than a first preset threshold, it indicates that for a large amount of data transmission, the step of establishing m data transmission channels between the smart mobile hard disk and the electronic device can be executed, thereby improving the data transmission efficiency of the smart mobile hard disk for a large amount of data transmission.

[0081] Optionally, the following steps may also be included:

[0082] Determine the remaining memory space of the other party;

[0083] When the data memory size is greater than or equal to the remaining memory space size, determining a first releasable memory space of the other party;

[0084] Determine the sum of the remaining memory space size and the first releasable memory space to obtain a first free memory space;

[0085] When the ratio between the data memory size and the first free memory space is less than a preset ratio, executing the step of establishing m data transmission channels between the smart mobile hard disk and the electronic device;

[0086] When the ratio between the data memory size and the first free memory space is greater than or equal to the preset ratio, generating a prompt message, wherein the prompt message is used to prompt a user to stop transmitting the data to be transmitted;

[0087] or,

[0088] When the data memory size is smaller than the remaining memory space size, determining a second releasable memory space of the other party;

[0089] The step of establishing m data transmission channels between the intelligent mobile hard disk and the electronic device is executed, and the other party is instructed to execute a memory release operation so that the other party vacates free memory space corresponding to the first releasable memory space.

[0090] The preset ratio may be preset or set by system default, and the preset ratio is a positive number less than 1, for example, the preset ratio is 0.9.

[0091] In the embodiment of the present application, the remaining memory space size of the other party can be determined. When the data memory size is greater than or equal to the remaining memory space size, it means that the memory of the other party is insufficient. Then the first releasable memory space of the other party can be determined. For example, some cache files, zombie files, and memory fragments can be cleaned up to release memory space to obtain the first releasable memory space. For another example, some unimportant files can also be compressed to obtain the first releasable memory space. Furthermore, the sum of the remaining memory space size and the first releasable memory space can be determined to obtain the first free memory space. When the ratio between the data memory size and the first free memory space is less than the preset ratio, it means that the memory is sufficient. The step of establishing m data transmission channels between the smart mobile hard disk and the electronic device can not only ensure the security of data transmission, but also greatly improve the efficiency of data transmission. When the ratio between the data memory size and the first free memory space is greater than or equal to the preset ratio, a prompt message can be generated. The prompt message is used to prompt the user to stop transmitting the data to be transmitted, that is, it can prompt the user that the memory is full and let the user clean up the memory by himself.

[0092] In an embodiment of the present application, when the data memory size is smaller than the remaining memory space size, it indicates that the memory is sufficient, and the other party's second releasable memory space can also be determined. For example, some cache files, zombie files, and memory fragments can be cleaned up to release memory space to obtain a second releasable memory space. For another example, some unimportant files can also be compressed to obtain a second releasable memory space. Thus, more memory resources can be guaranteed, and then the step of establishing m data transmission channels between the smart mobile hard disk and the electronic device is executed, and the other party is instructing the other party to perform a memory release operation, so that the other party can free up the free memory space corresponding to the first releasable memory space. This can not only ensure the security of data transmission, but also greatly improve the efficiency of data transmission.

[0093] Optionally, there is at least one intermediate device between the smart mobile hard disk and the electronic device; the above step 202, establishing m data transmission channels between the smart mobile hard disk and the electronic device, can be implemented as follows:

[0094] Determine a direct wired data transmission channel between the smart mobile hard disk and the electronic device, and obtain a data transmission channels; a is a natural number;

[0095] Determine a direct wireless data transmission channel between the smart mobile hard disk and the electronic device to obtain b data transmission channels, where b is a natural number;

[0096] Determine an indirect wired data transmission channel between the smart mobile hard disk and the electronic device established by any intermediate device of the at least one intermediate device, and obtain c data transmission channels; c is a natural number;

[0097] Determine an indirect wireless data transmission channel between the smart mobile hard disk and the electronic device established by any intermediate device of the at least one intermediate device, and obtain d data transmission channels; d is a natural number;

[0098] Acquire attribute information of each of the a data transmission channels, the b data transmission channels, the c data transmission channels, and the d data transmission channels to obtain n pieces of attribute information, where n=a+b+c+d;

[0099] Evaluate each data transmission channel according to the n pieces of attribute information to obtain n evaluation values;

[0100] According to the n evaluation values, m evaluation values ​​greater than a preset evaluation value are selected, and data transmission channels corresponding to the m evaluation values ​​are obtained to obtain the m data transmission channels.

[0101] Among them, the preset evaluation value can be pre-set or system default.

[0102] In an embodiment of the present application, there is at least one intermediate device between the smart mobile hard disk and the electronic device, and the direct wired data transmission channel between the smart mobile hard disk and the electronic device can be determined to obtain a data transmission channel; a is a natural number, and the direct wireless data transmission channel between the smart mobile hard disk and the electronic device is determined to obtain b data transmission channels; b is a natural number, and the indirect wired data transmission channel between the smart mobile hard disk and the electronic device established by any intermediate device in at least one intermediate device is determined to obtain c data transmission channels; c is a natural number, and the indirect wireless data transmission channel between the smart mobile hard disk and the electronic device established by any intermediate device in at least one intermediate device is determined to obtain d data transmission channels; d is a natural number, and the attribute information of each data transmission channel in a data transmission channel, b data transmission channel, c data transmission channel and d data transmission channel is obtained to obtain n attribute information, n=a+b+c+d, and the attribute information may include at least one of the following: channel type, channel bandwidth, channel data transmission rate, channel distortion rate, channel packet loss rate, channel signal-to-noise ratio, etc., which are not limited here.

[0103] Furthermore, each data transmission channel can be evaluated according to the n attribute information to obtain n evaluation values. Specifically, according to the mapping relationship between the preset attribute information and the evaluation value, the evaluation value corresponding to each of the n attribute information can be determined based on the mapping relationship, and then these evaluation values ​​can be weighted to obtain n evaluation values. According to the n evaluation values, m evaluation values ​​greater than the preset evaluation value are selected, and the data transmission channels corresponding to the m evaluation values ​​are obtained to obtain m data transmission channels. In this way, high-quality data transmission channels can be preliminarily screened for data transmission to ensure data transmission security and efficiency.

[0104] It can be seen that the method for using the smart mobile hard disk described in the embodiment of the present application is used to realize data transmission between the smart mobile hard disk and the electronic device, and obtain data to be transmitted; the data to be transmitted is located on the smart mobile hard disk or the electronic device; m data transmission channels are established between the smart mobile hard disk and the electronic device, and m is an integer greater than 1; attribute information of each of the m data transmission channels is obtained to obtain m attribute information; the data transmission rates of the m data transmission channels are evaluated according to the m attribute information to obtain m data transmission rates; the security evaluation values ​​of the m data transmission channels are evaluated according to the m attribute information to obtain m security evaluation values; the data to be transmitted is transmitted according to the m data transmission rates and the m security evaluation values, and further, the data to be transmitted can be dynamically processed based on the performance of each data transmission channel to achieve efficient and secure data transmission, which is helpful to improve the data transmission efficiency of the smart mobile hard disk in the case of large-scale data transmission.
